For a full description of the functions delivered in CICS TS V2, refer to Functions Delivered in CICS TS V2.2 below.

A description of EJB technology and its benefits is given in the Enterprise JavaBeans — Overview section.

CICS TS V2.2 is intended for high-volume production both for customers wishing to exploit Java and EJB technology, and for those whose main emphasis is on applications based on procedural programming models. CICS TS V2.2 is the replacement for CICS TS V2.1, CICS TS V1.3, and earlier releases of CICS; it is the recommended migration target for all CICS customers. CICS TS V2.2 provides an evolutionary path, enabling customers to enhance their installations by adopting new technology at their own pace. The limitations that applied to CICS TS V2.1 do not apply with this release: CICS TS V2.2 is delivered through customized offerings; and it does not have an early discontinuance of program services.

The capabilities for Java and EJB technology in CICS TS V2.2 include support for Java SDK 1.3 and the new persistent, reusable JVM, providing enhancements to robustness and integrity. A full implementation of the EJB 1.1 security specification is delivered. Use of a Lightweight Directory Access Protocol (LDAP) server, available with the operating system, is supported for Java Naming and Directory Interface (JNDI). Standard WebSphere™ EJB deployment tooling is exploited, in place of the product-specific tools provided with CICS TS V2.1. Extensive scenario testing has been carried out to ensure the reliability of the new function meets CICS's established standards of integrity for production use of business-critical applications. There are improvements to serviceability including, for example, generating trace information at more trace points.

Euro Currency

This program is EuroReady.

For more information on the implications of the euro, visit the IBM euro Web site at:

http://www.ibm.com/euro

EuroReady Products: IBM considers an IBM product to be EuroReady if the product, when used in accordance with its associated documentation, is capable of correctly processing monetary data in the euro denomination and of respecting the euro currency formatting conventions (including the euro sign). This assumes that all other products (for example, hardware, software, and firmware) that are used with this product are also EuroReady. IBM hardware products that are EuroReady may or may not have an engraved euro sign key on their keyboards.

Currently, EuroReady status applies primarily to IBM products specific to the EMU countries. Products that are not specific to these countries are deemed to be "not ready" for euro unless otherwise stated in the product's country-specific specifications.

Product Positioning

CICS is IBM's premier transaction processor for the z/OS and OS/390 environments, enabling thousands of enterprises to run business-critical workloads totalling billions of transactions per day, with a financial value of trillions of dollars. Many of these enterprises see significant advantages in building upon their core investment in CICS skills and applications, and extending that investment to provide the basis for their new e-business solutions.

CICS TS V2 continues to provide an efficient and effective environment for applications written in COBOL, PL/I, C, C++, and other languages. This version strengthens application development capabilities, enables enhanced re-use of 3270 applications, and enables applications to manipulate XML directly.

CICS support for Java has evolved through a number of stages. With Version 2, CICS TS now provides a robust, high-performance environment for enterprise applications written in Java. Its exploitation of the innovative persistent, reusable JVM, together with an architecture providing a separate JVM for each of the transactions running in a CICS region, ensures that Java applications have a high degree of isolation from each other, while achieving execution speed which is comparable with that of procedural languages. A range of Java services enables applications to exploit the strengths of CICS via open Java Enterprise APIs. VisualAge^® for Java and WebSphere Studio may be used to develop these applications and deploy them under CICS; no special tools are needed.

By supporting EJB session beans, CICS provides another dimension for application architects. Stateful session beans may be seen as a contemporary equivalent of pseudo-conversational programs and are suitable for a wide range of applications. The technology also enables transactional peer-to-peer interoperation with WebSphere Application Server using IIOP and may be used as an advanced connector. By exploiting the WebSphere EJB Container, CICS enables construction of re-usable business logic components, which are binary portable between CICS and WebSphere and may be deployed in either environment using the same tools. Where an EJB component needs to incorporate procedural logic modules to accomplish its business function, CICS enables this mixed-language component to run in a single execution environment with good isolation from other components, improving robustness and manageability.

CICS supports those parts of the IBM Framework for e-business and the Java 2 Enterprise Edition (J2EE) specification that are appropriate to its role as a server for core transactional business logic. It provides a run-time environment optimized for business logic written as enterprise beans that can run alongside, and interoperate with, business logic written in languages such as COBOL. Both EJB applications and COBOL applications can access existing (and new) DB2, IMS™ DB, and VSAM data concurrently and with complete integrity. By allowing new enterprise beans to run simultaneously in the same managed run-time environment as, for example, traditional 3270-based applications, CICS enables the same operations personnel to support multiple styles of application.

In summary, the role of CICS TS V2 in an enterprise solution on OS/390 or z/OS is to enable:

Efficient and optimized extension and re-use of existing CICS applications and business logic
Enterprises with a strong investment in CICS skills and infrastructure to create applications using new technologies by building on those skills
Support of mixed application types and workloads within a single CICS system
Re-use of existing DB2, IMS DB, and VSAM data from Java and EJB applications

Functions Delivered in CICS^® TS V2.2

The following are the principal new functions provided in CICS TS V2.2. Some of these functions, although not previously delivered, were described in the previous announcement of March 2001. Others of these functions already described in that announcement were delivered in CICS TS V2.1; these functions are indicated by an asterisk.

Enhanced Java™ Support

CICS support for Java has been dramatically enhanced. Firstly, the level of Java supported has been upgraded to Java 2 at SDK V1.3.1 level. Secondly, CICS exploits a completely new Java Virtual Machine (JVM) specially designed to optimize performance for short running programs such as CICS transactions. Thirdly, support for Java Enterprise APIs such as JDBC, JNDI, and RMI has been significantly enhanced. Fourthly, CICS applications can now use the Common Connector Framework (CCF) client API to allow portability between CICS and non-CICS servers of Java application classes that invoke CICS programs.

CICS Support for the Persistent, Reusable JVM: Support for the JVM has moved forward in CICS TS V2.2 to the IBM Developer Kit for OS/390^®, Java 2 Technology Edition, V1.3.1, known as the persistent, reusable JVM. Note that, unlike the position with CICS TS V2.1, there is no requirement to install a special enhancement; the enhancement has been incorporated into this level of the JVM. The use of this JVM enables significant performance optimizations for any Java program running in CICS, including enterprise beans. The performance benefits accrue from two sources. Firstly, by serially reusing a JVM the initialization cost for a Java application is dramatically reduced. Secondly, by discarding all the application objects created by the Java program in one go, when the program terminates, the performance overhead of the more usual garbage collection mechanism is effectively eliminated.

The persistent, reusable JVM supports special techniques that enable system and middleware code to re-initialize the JVM before it is reused for the next Java program. This ensures that there can be no interference between the applications, or between programs running on behalf of different end users, that serially reuse the same JVM. CICS supports a set of JVM instances ready for use within each CICS address space and provides management of the pool of JVMs to optimize throughput and to allow Java classes to be replaced without requiring that CICS be restarted.

* SQLJ/JDBC Support: CICS Java applications can access DB2^® data via the Java DataBase Connectivity (JDBC) and SQLJ APIs. The JDBC API uses the dynamic SQL model; the SQLJ uses the static SQL model. Support is provided via a type2 JDBC driver provided by DB2 for OS/390 at a JDBC 1.2 API level. The DB2 support has been upgraded to support the persistent, reusable JVM. JDBC and SQLJ requests are converted by the JDBC driver into EXEC SQL requests and then routed into the existing CICS-DB2 Attachment Facility. All existing tuning and control parameters available to CICS DB2 applications can be used with CICS Java applications using JDBC and SQLJ.

* JDBC Access to IMS™: JDBC access to IMS Version 7 Database Manager (DB) data was initially provided with IMS V7, at its general availability, for Java applications running under control of the IMS Transaction Manager. This support has been extended to provide JDBC access to IMS DB data from Java applications running under CICS Transaction Server for z/OS™ Version 2. It requires IMS V7, with service applied, or IMS V8.

Java Naming and Directory Interface (JNDI): JNDI is a Java API that provides directory and naming functionality for Java applications. In CICS TS V2, the JNDI API enables an enterprise bean or other Java program to look up a name or to locate an enterprise bean, local or remote, which, if desired, can then be invoked.

The JNDI API is mapped to an external naming directory server; a suitable JNDI server is a requirement. CICS TS V2.2 introduces support for a Lightweight Directory Access Protocol (LDAP) server as a JNDI service provider. An LDAP server with a CORBA object reference schema is required; the LDAP server in the SecureWay^® Security Server, licensed as part of the base z/OS or OS/390 operating system, meets this requirement, and can provide support across a Parallel Sysplex^®. Alternatively, a CORBA Object Services (COS) naming directory server can be used. WebSphere™ Application Server, Advanced Edition for Windows NT^® V3.5, or later, meets the requirements (refer to the Software Requirements section). The use of the LDAP server available with the operating system enables simpler interoperation with WebSphere Application Server V4.0 for z/OS and OS/390, for example if using entity beans running under WebSphere, since both CICS and WebSphere can then use the same LDAP server.

* The CICS Connector for CICS TS: CICS TS V2 introduces the CICS Connector for CICS TS, providing an option for a Java program or enterprise bean to communicate with an existing (non-Java) CICS application typically running under another CICS system. The non-Java program can be written in any supported language. Communication is by means of a COMMAREA within the local system or to any CICS system that supports DPL, such as CICS/ESA^® V4.1.

The CICS Connector for CICS TS supports the Common Connector Framework (CCF) client interface, an API that provides a standard way for a Java program to interact with an application server such as CICS. The recommended method of creating an enterprise bean that uses the CICS Connector for CICS TS is by means of VisualAge^® for Java, using its Enterprise Access Builder (EAB). Alternatively, other products that provide similar function may be used.

The CICS Connector for CICS TS is compatible with CICS Transaction Gateway Version 3, and later. Command beans generated by VisualAge for Java that use the CCF interface provided by CICS Transaction Gateway are binary portable to run under CICS TS V2.2 and use the CICS Connector for CICS TS. Other beans that use the underlying Java ECI interface can also be migrated to CICS TS V2.2.

As compared to the alternative of using the JCICS classes for a similar function, the CICS Connector for CICS TS has advantages: (a) portability, in that the code can be used from a CICS or non-CICS Java environment; (b) the availability of VisualAge for Java tooling for this function.

* Enhancements to CORBA Interoperability: Support for inbound Internet Inter-ORB Protocol (IIOP) requests from CORBA clients to CICS Java applications was introduced in CICS Transaction Server for OS/390 Version 1 Release 3. This support, and the implementation of the Object Request Broker (ORB), have been enhanced in CICS TS V2 to support CORBA 2.1 and IIOP 1.1.

The new functions that have been added are:

Support is provided for outbound IIOP. This means that CORBA applications can now act as both client and server.
CICS TS V2 method invocations may participate in Object Transaction Service (OTS) distributed transactions. (Note that the OTS term "transaction" is analogous to a distributed unit of work.)
Longer values of up to 255 characters are allowed for REQUESTMODEL options MODULE, INTERFACE, and OPERATION.

These new functions provide the necessary infrastructure for enterprise beans to communicate using the Java RMI interface.

EJB Support

CICS TS V2.2 supports session beans at EJB 1.1 specification level. A description of the EJB architecture, and session beans in particular, is given below: refer to Enterprise JavaBeans — Overview . Enterprise beans run in a container. CICS uses the common WebSphere container exploiting collaborator classes that map the infrastructure services that the container needs to the underlying CICS functions. This common implementation helps ensure binary compatibility for enterprise beans deployed on any of the WebSphere application servers and on CICS TS V2.

Enterprise beans running in CICS can be developed using any application development tool that supports EJB 1.1. The enterprise beans are deployed using the standard WebSphere Application Assembly Tool. The enterprise bean developer does not need to have knowledge about the platform on which the bean will be executed and hence does not need any CICS expertise.

Enterprise beans running on CICS can use all the Java capabilities described in the previous sections as well as JCICS classes to exploit CICS functionality. Note, however, that use of the JCICS functions means that the bean will not be portable to non-CICS platforms. Use of the JCICS classes or CCF to LINK to an existing procedural program (written, for example, in COBOL) allows existing business logic to be exposed to the outside world as an enterprise bean. The client applications need not be aware that the enterprise bean's business logic is actually implemented in COBOL.

EJB Run-Time Functions

All of the above enhanced Java support capabilities may be used by those exploiting EJB technology. In addition, the following functions are specific to EJB support.

* Support for Enterprise Beans: CICS TS V2.2 supports session beans, written to the EJB 1.1 specification. It incorporates an EJB container derived from the EJB container in WebSphere Application Server. The use of this container enables binary portability of applicable enterprise beans developed with WebSphere for execution under CICS.

A session bean can also perform a JCICS link to an existing CICS transaction in COBOL or any other supported language. This allows a session bean to be effectively a wrapper of an existing procedural CICS application. It can also use the CICS Connector for CICS TS, newly introduced in this product, allowing it to communicate by a COMMAREA with a CICS application running in the same or another CICS system. The other CICS system can be any CICS system that supports DPL, such as CICS/ESA V4.1.

Support for entity beans is not provided by CICS TS V2.2. EJB applications running under CICS may, however, call entity beans hosted by other products, such as WebSphere Application Server V4.0 for z/OS and OS/390.

Data Access Beans are a practical alternative to entity beans for access to data from enterprise beans running in CICS TS V2. These enable read and write access to data in relational databases that support the Java Data Base Connectivity (JDBC) API, such as DB2 for OS/390. The Data Access Beans use a common SQL syntax, so they work both on OS/390 and on workstation platforms. In particular, the beans provided as part of VisualAge for Java professional edition may be used. There are three such beans: Select Bean, Modify Bean, and ProcedureCall Bean. VisualAge for Java includes Smart Guides that make them even easier to use. One of the Smart Guides is an SQL Assist Smart Guide, which allows the visual composition of an SQL statement.

* EJB Access to Other Resources: Also available to enterprise beans are the facilities of JCICS, which enable access to VSAM data and CICS resources. Access to DL/I data is available via a program written in, for example, COBOL, invoked by a JCICS link, or invoked using the CICS Connector for CICS TS. Refer also to JDBC Access to IMS section, above.

EJB Security: In CICS TS V2.2, the Java 2 security policy mechanism and the security specification of the EJB Version 1.1 architecture are supported. Specifically:

The getCallerPrincipal method is implemented. It returns a Principal object whose getName method returns the distinguished name of the EJB client. When the client is authenticated with an SSL certificate, the distinguished name is extracted directly from that certificate, otherwise it is generated from a user-replaceable module, DFHEJDNX.
The JVM is controlled by Java 2 security policies that can be customized by the user.
The security roles and method permissions in the deployment descriptor will be recognized and honored.

The EJB security solution in CICS TS V2.2 uses the System Authorization Facility (SAF) interface to exploit services of the SecureWay Security Server in z/OS and OS/390 (formerly the Resource Access Control Facility [RACF^®]). This support requires APARs OW46859 and OW49190 to OS/390 or z/OS. The support provides:

Method authorization checks, to determine whether a user is in a role that is authorized to execute a given method on an enterprise bean
A full implementation of the EJB 1.1 security API, isCallerInRole

A new Java-based CICS utility is introduced to ease the administrative burden of defining profiles for the SecureWay Security Server.

In addition to EJB security as described above, CICS TS V2.2 provides a capability for security authentication of users accessing CICS over IIOP, providing secure interoperability between CICS and other IBM and non-IBM systems using the SSL client authentication protocol.

Note that when used with non-EJB applications, CICS TS V2.2 has the same security and auditability features as CICS TS V1.3. CICS transaction and resource security continue to apply when the CICS API is used, including the JCICS API.

Application Development and Deployment Functions in Support of EJB

EJB Support Tools: As indicated in the initial announcement, changes have been made in CICS TS V2.2 to further simplify and to provide common solutions with the WebSphere platform.

The tools provided in CICS TS V2.1 are not shipped with this release. The CICS JAR Development Tool for EJB Technology, CICS Development Deployment Tool for EJB Technology, and CICS Production Deployment Tool for EJB Technology are no longer required.

Introduced in this release is the use of the Application Assembly Tool (AAT). This is a general tool also used by members of the WebSphere Application Server V4.0 family (but note that this is not the same tool as that referred to as the AAT in WebSphere Application Server V4.0 for z/OS and OS/390). This is a workstation-based tool running on Windows NT or Windows^® 2000; it is used to build JAR files ready for the run-time environment, and is required in order to prepare enterprise beans for installation into the CICS TS V2.2 system. The tool allows users to define the contents of the JAR file by indirectly editing the deployment descriptor, and will then produce the generated code required to run in an EJB environment. The AAT is shipped as a component of WebSphere Application Server, Advanced Single Server Edition V4.0, which is included for this purpose as an element of CICS TS V2.2. Note that V4.0.1 is the minimum required level; this is the level shipped with CICS TS V2.2.

A new tool is supplied as part of CICS TS V2.2. The resource manager for enterprise beans is a Web-based tool that gives an application developer the ability to work with EJB resources in CICS without having to use a CICS terminal. It provides access to the common functions associated with CorbaServers and DJARs, gives diagnostic information for DJARs that have not been correctly installed, and offers information about the naming server and beans that are published to it.

For use of a debugger with the JVM, the JVM in CICS supports the Java Platform Debugger Architecture (JPDA), which is the standard debugging mechanism in the Java 2 platform. This architecture provides a set of APIs that allow the attachment to a JVM of a remote debugger that conforms to JPDA, such as IBM Distributed Debugger V9.1, or later.

CICS EJB Samples: Three EJB samples are shipped with CICS TS V2.2. One is simple, and is intended for use for installation verification purposes. The second is based on the first, but includes Web components that can be installed in a J2EE Web Application Server, such as WebSphere Application Server Version 4.0.

The third is an online banking sample. It consists of an HTML form, a Java servlet plus JavaServer Pages, an enterprise bean, DB2 data tables, and two CICS server programs written in COBOL. The sample is started from a Web browser, and displays a form in which the user enters information. This invokes a servlet, which interacts with the enterprise bean. The enterprise bean uses the CCF interface of the CICS Connector for CICS TS to link to the CICS COBOL server programs, which retrieve data from the DB2 database. Information received by the enterprise bean is returned to the servlet, which uses JavaServer Pages to display it at the browser. This sample requires DB2 Server for OS/390 Version 5.1, or later, and a J2EE Web Application Server, such as the shipped WebSphere Application Server, Advanced Single Server Edition V4.0.

Systems Management Functions Supporting EJB

A number of new CICS resources have to be defined to implement support for enterprise beans. In particular a new resource, known as a CorbaServer, has to be defined to specify the properties of the container. In addition the deployed JAR files can be pre-defined or installed automatically. The enterprise beans in a deployed JAR file can be published to the JNDI namespace either explicitly or automatically by requesting the AUTOPUBLISH option on the CorbaServer definition. These resources are defined and managed using the usual CICS RDO, SPI, and CEMT functions. The method request executed by the enterprise bean runs under a CICS transaction ID and is associated with a standard CICS user ID. Hence the usual CICS security and monitoring mechanisms apply to enterprise bean invocations just as they do for procedural CICS transactions. This approach allows existing operational procedures to continue to be used when using enterprise beans and removes the need for the system programmers to have a detailed understanding of the EJB architecture.

Two new CICS-supplied transactions are introduced:

CREA gives system programmers a view of the beans and methods within a JAR file and offers them the ability to associate those beans and methods with CICS transaction IDs. The tool will take into account any installed definitions to supply default values for the transaction IDs, which the user is then free to modify. The result of the associations is the generation of an optimum list of REQUESTMODELs that will lead to incoming requests for beans within that JAR file using the transaction IDs specified using the tool. The REQUESTMODELs generated can be installed directly into CICS, written to the CSD, or both. This tool removes the need for a system programmer to derive REQUESTMODEL definitions and enter them using CEDA.
CREC is a read-only version of CREA. It offers a view of the JAR file and the associations implied by installed REQUESTMODELs. It does not offer the user the ability to change the associations or generate REQUESTMODELs.

In addition, a new Java-based CICS utility is introduced to ease the administrative burden of defining profiles for the SecureWay Security Server.

CICS Transaction Server for z/OS Version 2 incorporates a new version of CICSPlex^® System Manager. This provides major new functions, many of which are in support of EJB technology.

* CICSPlex SM Management of the EJB Server: A range of new and modified functions is provided in CICSPlex SM for its support of the EJB server. These functions are:

New operator views for CorbaServers and JAR files, and related actions PUBLISH, RETRACT, and DISCARD
Modified operator views for transaction and request models
Equivalent changes to the Web user interface for the operator view changes in the previous two points, and for beans
New Business Application Services (BAS) resource definition views for CorbaServers and JAR files
Modified BAS resource definition views for transactions and request models
Changes to the CICSPlex SM API for the support of CorbaServers, JAR files, and beans

* Workload Management for Enterprise Beans: CICSPlex SM provides dynamic workload balancing of enterprise beans executing in CICS-provided CorbaServers. This extends to enterprise beans the distributed routing program model introduced in CICS TS V1.3. All existing facilities provided by CICSPlex SM in this context, such as workload separation and application availability, are provided for enterprise bean invocation. The customer can write a user-replaceable module to customize the routing logic.

In workload balancing, the roles are:

The requester, in which the routing request originates, which, for example, can be external client code invoking the enterprise bean by an IIOP work request, or could be another logical EJB server.
The routing region, in which the decision is taken as to where the requested transaction should be run. This is normally a CICS listener region, and it must be running CICS TS V2.
The target region, in which the identified transaction is run. It must be running CICS TS V2.

In this context, a CICSplex consists of a number of cloned routing regions and cloned target regions. Each target region may run a number of CorbaServers. Note that CICSPlex SM workload management is compatible with, and complementary to, MVS™ TCP/IP connection balancing across multiple listener regions.

New Facilities for CICS Exploitation of Procedural Programming

* Integrated Translator for COBOL and PL/I Applications: Previously, development of new application programs has required that the source code should first be passed through a CICS-supplied translator that translates the EXEC CICS statements into statements in the appropriate language. Then, as a separate step, the code would be passed through the compilation process. Now, CICS TS V2 delivers an Integrated Translator for use with the new COBOL and PL/I compilers, which together perform the compilation and translation process in a single step. The major benefit of this is in the debug process, as the lines of code stepped through with the IBM Debug Tool in the compiled code exactly match the original written source file. There is no requirement for use of an intermediate listing containing the translator-generated calls. This also means that the whole process is simpler, easier, and less liable to error.

Refer to the Software Requirements section for details of the necessary levels of the COBOL and PL/I products required for this function. Lower levels of these compilers continue to be supported, but without the benefits of the Integrated Translator.

CICS COBOL and PL/I XML Application Capability: The CICS COBOL and PL/I XML Application Capability provides the capability to parse XML documents directly in CICS COBOL and PL/I applications. The XML Enabler for COBOL and PL/I can be used to enhance your existing high-performance CICS transactions written in COBOL and PL/I in a B2B environment by supporting XML document interchange. CICS supports the transmission of XML documents in the data portion of a CICS message.

This capability is being provided through COBOL and PL/I and supports CICS TS V1.3 as well. It requires IBM Enterprise COBOL for z/OS and OS/390 Version 3, or IBM Enterprise PL/I for z/OS and OS/390 Version 3. These compilers also support data encoded in the various Unicode formats, and supply methods for conversion either way between these formats and EBCDIC.

3270 Bridge Enhancements: The CICS 3270 bridge was introduced in CICS Transaction Server for OS/390 Version 1 Release 2, and enhanced in CICS TS V1.3. It was used as the basis for the CICS Web bridge, which maps the output of 3270 applications to HTML data in conjunction with the facilities of CICS Web Support. It has now been used as the basis for a LINK interface to the 3270 bridge that allows a 3270 transaction (that meets certain requirements) to be driven using client ECI, host EXCI calls, and DPL or LINK. This provides an alternative to the previous asynchronous START BREXIT interface. It means that client environments that have LINK interfaces to CICS, such as workstation-based client programs using ECI, OS/390 client programs using EXCI, and CICS systems using the local or remote (DPL) EXEC CICS LINK interface, are now supported. It may be used in conjunction with the new support for ECI over TCP/IP.

Other new functions introduced include the ability to workload balance transactions using the bridge environment in a CICSplex, the capability of renaming the bridge facility TERMID, and a new SPI for managing bridge facilities.

Load Module Scanner: The Load Module Scanner (which was made available for CICS TS V1.3 in November 2000 via the service channel but was not included in CICS TS V2.1) makes available a facility to scan a load library containing CICS application programs, and compare the EXEC CICS commands in them with those in a filter table. A filter table is provided that will determine those programs that will not work under the CICS 3270 bridge. Another filter table is provided of commands that may cause programs not to be threadsafe. This function can also employ user-defined filter tables, allowing it to be used for any other purposes required by the user.

* Enhancements to Function Shipping of Remote File Requests: The remaining differences between processing of API requests for local and remote files have been virtually eliminated. RESP and RESP2 responses (apart from SYSIDERR) are now identical to their local equivalents, so that the application programmer can be totally unaware of the location of the file.

In addition, system files, for example, the Business Transaction Services (BTS) repository, can now be shared across multiple regions without the requirement to use RLS.

* CICS Web Bridge Enhancements: A range of enhancements to the CICS Web bridge removes a number of limitations and allows it to support a larger subset of current 3270 and BMS applications. These enhancements include:

Support for dynamic changing of BMS field attributes.
Support for multiple maps. Multiple maps in a single screen image are correctly positioned; and where maps overlap, a best effort is made to generate a satisfactory image.
Retention of map to support the SEND MAP DATAONLY command.
Changes to terminal control support to improve performance and to allow BMS and terminal control commands to be mixed in the same application.
Support for the RECEIVE BUFFER command and 3270 structured fields.
Improvements to diagnostic facilities, particularly in 3270 terminal control.
Removal of the restriction that prevented a different map name from being used on a RECEIVE MAP command from that in a preceding SEND MAP.

* Additional CICS Web Support API Enhancements: The CICS Web support API is enhanced by the addition of two new CICS commands to assist Web-aware applications in retrieving HTML forms data. The commands are:

EXEC CICS WEB READ FORMFIELD
EXEC CICS WEB STARTBROWSE FORMFIELD

They work with URL-encoded forms or multipart forms; HTTP requests using the "POST" method; and HTML form INPUT elements of type TEXT, PASSWORD, CHECKBOX, RADIO, SUBMIT, HIDDEN, and FILE (but they do not provide support for "GET" or for access via the plugin).

* Web Certificate Auto-Registration Feature: The Web certificate auto-registration feature allows a Web client of CICS with an SSL client certificate to register that certificate to a user ID in the external security manager's database. Previously, it was necessary for a security administrator to register the certificate manually, using RACDCERT or a similar command. With this feature, a client can be prompted to enter a user ID and password with the HTTP basic authentication protocol, and if these are successfully validated, the client certificate is automatically registered to that user ID. Other options allow CICS to permit only registered client certificates to be used on a connection, or for HTTP basic authentication to be used for authentication regardless of whether SSL is also used.

* CICS — Language Environment^® Enhancements: A range of changes has improved the function of CICS with Language Environment, principally in the areas of usability, serviceability, and performance. Required levels of Language Environment apply to these items.

Usability enhancements include:

Language Environment and CICS diagnostics placed together in the transaction dump
Fewer trace entries caused by taking a dump, so the trace table is more useful
Formatting of some Language Environment control blocks in a CICS transaction dump
A new transaction CLER to allow CICS systems administrators to inquire upon and set values for a subset of global Language Environment run-time options

Serviceability improvements include:

Integration of Language Environment and CICS IPCS verb exits
Extensions to some CICS trace points to trace the application's register save area

Performance enhancements include:

Dynamic storage tuning controlled by a new SIT option AUTODST

VSAM Control Interval Deadlock Avoidance: An enhancement to file control is included in CICS TS V2.2 that removes the risk of unanticipated deadlocks due to access to records that reside in the same VSAM control interval.

Enhancements to Network Connectivity for e-business Enablement

Some of these enhancements may also be exploited by applications written to the EJB programming model.

ECI over TCP/IP: This function allows client applications to use TCP/IP communication with the External Call Interface (ECI) directly to CICS without the use of any intervening products. Previously, to communicate directly with CICS on System/390^®, clients have had to use SNA LU6.2, or use TCP62 (APPC over TCP/IP) support with the AnyNet^® feature of SecureWay Communications Manager for OS/390. The use of native TCP/IP directly into CICS removes the need for the AnyNet feature of SecureWay Communications Manager for OS/390, and any SNA configuration on z/OS or OS/390, and thereby simplifies the administration of large networks of clients. No change is required to the client or to the server applications.

CICS Transaction Gateway V4, CICS Transaction Gateway V3, or CICS Universal Clients V3 applications can take advantage of this capability without change.

* Enhancements to CICS Exploitation of TCP/IP Services: Enhancements are included in CICS TS V2 that provide improved services to the CICS functions that use the Sockets domain, namely the HTTP and IIOP support:

Socket management, which enables you to specify the maximum number of sockets (MAXSOCKETS) that the CICS sockets domain should have active at one time.
Functions that are used by the enhanced CORBA support:
- Outbound socket support. This allows CICS to initiate an IP connection. (The term "connection" is here being used in its IP sense, not as a set of sessions between two systems.)
- Asynchronous receive support, allowing a task that initiates a receive request on an IP connection to continue to execute concurrently.
- Shared sockets, created by one task and remaining active for a number of tasks.

These enhancements offer a range of benefits in terms of management and improved scalability and performance.

* Connection Optimization: Support for Domain Name System (DNS) registration has been extended, improving the connection optimization that was provided in CICS TS V1.3. Connection optimization uses DNS to balance IP connections and workload in a sysplex domain. This enhancement to connection optimization extends the RDO options and operator interfaces that allow CICS TCP/IP services to register with the OS/390 workload manager in order to take part in DNS connection optimization.

* CICS Support for VTAM^® LU Alias Facility: The ability has been introduced to coexist with the VTAM capability to dynamically generate an LU alias for a cross-network CDRSC (cross-domain resource). It has also been introduced for predefined LU aliases. VTAM LU alias facilities provide improved connectivity and interoperability for terminal networks. Their use facilitates the growth of SNA networks, and allows integration of the networks of multiple enterprises. The addition of this support enables CICS to use an LU alias for terminals and workstations (not APPC synclevel 2), ensuring unique names across a CICSplex comprising terminal-owning regions (TORs) and application-owning regions (AORs). CICS regions that are owned by different enterprises, and which may use the same VTAM network names (netnames), can interconnect without creating any problems because of the duplicate netnames. This facility can be beneficial, for example, for organizations that offer bureau services.

Improved Application Availability

Enhanced DB2 Facilities

CICS-DB2 Performance: The CICS-DB2 Attachment Facility is enhanced in the level shipped with CICS TS V2.2 to exploit CICS open transaction environment (OTE) function. When CICS TS V2.2 is connected to DB2 V6.1, or later, the attachment facility will execute using CICS open TCBs and will utilize DB2 function to move DB2 connections and threads between TCBs. CICS-DB2 applications coded to threadsafe standards, and defined to CICS as threadsafe, may benefit from reduced TCB switching. For threadsafe applications making heavy use of EXEC SQL, the reduced TCB switching should provide a significant performance improvement.

DB2 Group Attach: This new function allows a CICS customer to exploit the DB2 facility whereby the name may be specified as a DB2 Data Sharing Group instead of an explicit DB2 subsystem name. Each group can contain one or more DB2 subsystems. This simplifies application-owning region (AOR) cloning within a sysplex and provides a greater level of availability.

DB2 Group Attach requires DB2 Universal Database^® for OS/390 Version 7.1, with APARs PQ44614, PQ45691, and PQ45692.

DB2 Exploitation of the RMI Purge Option: A new Resource Manager Interface (RMI) purge option is introduced in CICS TS V2.2. This allows the writer of a task-related user exit (TRUE) to specify whether, before calling it, the RMI should defer purge and deactivate runaway. This offers an operational enhancement by making it easier to recover from system stall situations in CICS. The CICS-DB2 Attachment Facility uses the new RMI purge option when CICS is connected to DB2 V6 or higher; this allows applications waiting in DB2 to be purged from CICS. Previously only forcepurge, with its danger of loss of integrity, was supported.

Enhanced Support for CICS Data-Sharing Servers

* Automatic Restart of CICS Data-Sharing Servers: The three types of CICS data-sharing servers are the named counter server, the coupling facility data table server, and the temporary storage data sharing server. For all of them, automatic restart is now supported using the services of the automatic restart manager (ARM) of the operating system. In addition, the servers can now wait during startup, using an event notification facility (ENF) exit, for the coupling facility to become available in the event of failure of the initial connection.

* System-Managed Rebuild Support for Coupling Facility Structures: A facility is provided in CICS to allow the automatic rebuild, in planned reconfiguration scenarios, of coupling facility structures for the CICS coupling facility servers, namely temporary storage, coupling facility data tables, and named counter servers. This facility exploits the Cross-System Extended Services^® (XES) system-managed rebuild support included in the operating system. For OS/390 V2.10 and z/OS V1.1, OS/390 or z/OS APAR OW39892 must be installed. No APAR is required for z/OS V1.2, or later.

A further benefit enabled by this function is system-managed coupling facility structure duplexing (refer to following item).

System-Managed Coupling Facility Structure Duplexing: CICS shared temporary storage queues, coupling facility data tables, and named counters can now be protected by system-managed coupling facility structure duplexing. This means that, in the event of a failure of a coupling facility, CICS applications using these servers continue to operate. This facility requires z/OS V1.2, with an enabling PTF — refer to z/OS information.

Sign-on Retention for Persistent Sessions: Previously, when using the CICS support for VTAM persistent sessions, in the event of a failure, CICS recovered only the terminal session and not the user's sign-on status, with the result that users had to sign on again after the recovery of the session. With this new function, CICS records the sign-on status of each user in the CICS catalog at the time of sign-on and sign-off. This enables it to retain a terminal's sign-on status across a failure in either CICS or VTAM, and to sign the user on again at reconnection.

The conditions under which a user sign-on status is restored after a recovery of persistent sessions are controlled by a number of options that are similar to those in the CICS extended recovery facility (XRF).

Checking Availability of MVS Logger: The overhead in checking that the connection to the MVS logger is still available has been dramatically reduced.

Systems Management Enhancements

CICSPlex SM Remote MAS Agent for Windows: CICSPlex SM provides Remote Managed Application System (Remote MAS) agent support to allow management of CICS on the Windows NT or Windows 2000 platform in TXSeries™ Version 4.3 (delivered in WebSphere Application Server Enterprise Edition for Windows NT), or later. This provides operations, real-time analysis, BAS support for the definition and installation of FEPI resources, and the ability to target CICS for Windows NT for dynamic workload management from CICS TS V2.2.

Also introduced is a facility to enable unattended installation of a CICS for OS/2^® remote MAS Agent.

CICSPlex SM Communications Enhancements: The communication (COMS) component of CICSPlex SM is a highly sophisticated component that provides transportation of requests and their responses across the MAS/CMAS network. It is built to cope with a dynamically changing network topology across multiple protocols. Fundamental to this is the concept of a ring between two CMASs (one session outbound; one inbound). In this release, various enhancements have been made to ring initialization and termination logic to cope with normal ring activation and various failure scenarios, which will provide increased resilience of the ring and consequently enhanced availability of the COMS component.

Improvements have also been made to storage management for ring initialization: large highly interconnected CMAS networks have been exposed to the possibility of consuming storage when the entire network is simultaneously restarted, and high usage at run time can also cause this effect. Storage allocated during this process previously was held on to for the life of the CMAS, providing the potential for other tasks to go short on storage (SOS). With this release, a new dynamic storage algorithm is incorporated that will reduce the likelihood of an SOS condition in the CMAS, and provide active management of an SOS condition in the event of an SOS being experienced in the CMAS.

The appearance of the CICSPlex SM Web user interface is improved * . Usability is enhanced by preventing the main navigation icons from being lost from view on the scrolling navigation frame. This can also be advantageous when using the Web user interface on devices with short screens, such as keyboard-based PDAs with a suitable Web browser.

* CICSPlex SM Business Application Services (BAS) Integration: The previous limit of 129,000 logical connections between related resources through Association Blocks has been raised to a much larger number. To avoid problems of long initialization time or timeout abend when the count of scoped resource definitions becomes large, the Consistent Check process has been made a configurable initialization parameter, with the default set to "off."

Other Benefits of CICS TS V2.2

Monitoring and Statistics Changes: Extensive changes and additions have been made to CICS monitoring data and statistics in CICS TS V2.2. These include:

The CICS statistics utility program now provides additional resource type options that allow selection of the global types of statistics data, to reduce the size of statistics reports when an overview is required.
The CICS sample statistics program has been enhanced * to support the new functions of CICS TS V2. In addition, it is now shipped as pregenerated executable code (as well as in COBOL source code), allowing it to be installed as supplied. The program may be invoked from a 3270 terminal or from a browser (using the CICS Web Support).
New system initialization parameters allow the user to specify statistics settings during CICS startup.
New performance class data fields are added in support of Open Transaction Environment, JVM, TCP/IP support, and CICS Web support.
There are new CICS statistics for CorbaServer resources and request model resources, and new global statistics for the JVM pool, TCP/IP support, and the CICS log manager.

* Information Center: As a major enhancement to the usability of its documentation, CICS TS V2 introduces an Information Center, the objective of which is to deliver information that corresponds to the tasks that are performed by the users of CICS. For more information, refer to the Publications section.

* Advanced ClusterProven™: CICS TS V2 is registered by IBM as Advanced ClusterProven. The IBM ClusterProven program introduces new high-availability requirements that may be applied to any combination of operating system, middleware, or end-user application. CICS TS V2 satisfies and exceeds the required technical criteria for this status. More information is available on the Web at:

http://www.ibm.com/servers/clusters

Enterprise JavaBeans — Overview

There are many advantages to the use of EJB technology. It provides the benefit common to all Java development of easy portability between different platforms, and further, it allows portability between different EJB-compliant transaction management products. Such a product is called an EJB server (sometimes known as Enterprise Java Server [EJS], or Enterprise Server for Java [ESJ]). By automating the infrastructure services, EJB technology allows the programmer to concentrate solely on business logic, without any need to consider transactional or environmental factors, thus increasing programmer productivity. Another benefit of EJB architecture is that it allows customization simply by altering attributes in the deployment of an enterprise bean — customization does not require alteration to the source code of the program. EJB architecture is scalable, allowing enterprise beans, once written, to be migrated from small-scale to large-scale environments.

All functions provided by CICS TS V2 for the support of EJB are in accordance with the J2EE Enterprise JavaBeans architecture, Version 1.1, as defined by Sun Microsystems, Inc. This specification, the Enterprise JavaBeans Specification, V1.1, Final Release, may be viewed at:

http://www.javasoft.com/products/ejb

The details of the implementation are unique to the particular product that is providing the EJB support, in this case CICS TS V2.2. Many of these details are internal, and concern the mapping of the functions defined by the EJB architecture to the existing tried and tested services of CICS. CICS TS V2.2 also provides extensive facilities for integration of existing functions with new applications developed using the EJB programming model. It supports session beans compliant with this specification.

An EJB server supports the execution of an enterprise bean , which is a reusable software server component, written in Java to the Enterprise JavaBeans specification. (This is similar to the way in which, in a nontransactional environment, a JavaBean is a reusable software component, written in Java, that is intended for use in a desktop or client application.) An enterprise bean is a transactional application program, or application program component, written in Java to the EJB programming model. This contrasts with an application program written, for example, in COBOL or C, to the CICS programming model.

An EJB server contains a standard set of components that provide a standard set of services, defined by the EJB specification, for the support of the enterprise beans. These services include support for the Remote Method Invocation (RMI) interface that enterprise beans use for communication, in the case of CICS TS V2.2 using the Internet Inter-ORB Protocol (IIOP); management services, which are provided by an EJB container; a distributed transaction management service; and security services.

An EJB container is a part of any EJB server. At run time, the EJB container creates and manages enterprise bean instances, and provides the services required by each enterprise bean running in it. Any number of enterprise beans can be deployed into an EJB container. Services provided by the EJB container include:

Lifecycle. The enterprise bean does not need to itself manage process allocation, thread management, object activation, or object passivation.
State management. The enterprise bean does not need to save or restore conversational object state between method calls.
Security. The enterprise bean does not need to authenticate users or check authorization rules. These functions are performed by the container on its behalf.
Transaction management. The enterprise bean does not need to specify transaction demarcation code in order to participate in distributed transactions. The EJB container manages the start, enrollment, commitment, and rollback of transactions on its behalf.
Persistence. The enterprise bean does not need to store or retrieve persistent data using a database. The EJB container can automatically manage persistent data on its behalf. This applies only to entity beans (not directly supported by CICS TS V2.2).

Enterprise beans are deployed into an EJB server. For this to happen, in the case where CICS is the EJB server, their execution environment is known as a CorbaServer, and is configured by a CorbaServer resource definition.

In the EJB context, any outside user of the services of the enterprise bean is known as a client. Interaction by a Java client with an enterprise bean is handled through two wrapper interfaces which are generated by the container: the home interface and the remote interface . These interfaces are defined as Java Remote Method Invocation (RMI) interfaces, accessed through IIOP.

The home interface is the mechanism by which a client specifies the enterprise bean that it will use. The client can create, remove, and (for entity beans only, see below) find existing instances of enterprise beans. When an enterprise bean is deployed in an EJB container, the container can register the home interface in a namespace that can be accessed remotely. Using the API of the Java Naming and Directory Interface (JNDI), any client can locate the home interface by name.
The remote interface allows a client to access the business methods of the enterprise bean. When a client creates or finds an instance of an enterprise bean, the container returns a remote interface for that instance of the enterprise bean. The remote interface intercepts all business method calls from the client, and inserts whatever transaction, state management, persistence (where applicable), and security services were specified when the enterprise bean was deployed.

The rules defining aspects of a particular enterprise bean are defined by what is called the deployment descriptor , a document written in eXtensible Markup Language (XML). This defines the lifecycle, security, transaction management, and persistence requirements of the enterprise bean.

There are two principal types of enterprise bean: session beans and entity beans .

A session bean is created by a client, and normally persists only for the duration of a single conversation or session with the client. (Thus, it is comparable to a pseudo-conversational transaction in conventional CICS.) Its function is typically to perform operations on business data; it may or may not be transactional; and it is not recoverable. If persistence of information is required, then the writer of the session bean must implement appropriate operations in the bean class methods, such as JDBC or SQL calls. A transactional session bean can either manage its own Object Transaction Service (OTS) transactions, or use container-managed transactions.
There are two types of session beans: stateful session beans and stateless session beans . A stateful session bean is one that has a client-specific conversational state, which it maintains across methods and transactions. A stateless session bean has no client-specific nontransient state.
An entity bean (not directly supported by CICS TS V2.2) is typically an object representation of business data. Typically, the data is maintained in a store such as a database. Unlike session beans, entity beans are relatively long lived: the data normally persists beyond the life of any client instance. An entity bean can be accessed by more than one client at the same time. An entity bean is recoverable: it will survive a crash of the EJB server. It may or may not be transactional, but if it is so, its transactional functions are performed by the container; the entity bean may not manage its own OTS transactions.
There are two types of persistence management for entity beans: bean-managed persistence and container-managed persistence . In the case of bean-managed persistence, the entity bean implements its own persistence operations, such as JDBC or SQL calls, allowing it to use data stored in any file or database manager. In the case of container-managed persistence, the writer of the entity bean does not need to have any awareness of the persistence operations.

The processes required for the deployment of enterprise beans into an EJB server are performed with the aid of tools for the purpose. A Java Archive (JAR) file can contain one or more Java beans, of different sorts, including enterprise beans. Where these Java beans are enterprise beans, the JAR file is referred to as an ejb-jar. An ejb-jar file is used to transfer an enterprise bean between the development environment and the test or run-time environment. An ejb-jar has a standard format and includes the Java classes, the Home and Remote Interfaces, and a deployment descriptor written in XML. When enterprise beans are deployed to CICS, they are in a "deployed JAR file," which means they include generated code specific to the CICS EJB container added to them by an EJB support tool.

Deployment, in the EJB context, means the series of tasks that take an enterprise bean from being Java code in an ejb-jar file, the state in which it may have been created by a developer, to the state in which it is made known to, and hence runnable in, a particular EJB server.

Additional Information

CICS Transaction Gateway V4.0.1: The CICS Transaction Gateway V4.0.1 will be shipped on December 31, 2001. This includes support for the J2EE Connector Architecture 1.0 specification, previously made available as a beta. This specification is an industry standard interface, published on September 17, 2001, and derived from IBM's Common Connector Framework (CCF) which was introduced with VisualAge for Java. For more information on CICS Transaction Gateway Version 4.0, refer to Software Announcement 201-187 , dated June 26, 2001.

Service for CICS Universal Clients V3.1: As announced on October 2, 2001, program services for CICS Universal Clients Version 3.1 are extended, and will now be available until December 31, 2002. For more information, refer to this announcement as listed in the Reference Information section, above.

CICSPlex SM V1.3: Note that, as announced on August 7, 2001, CICSPlex System Manager for MVS/ESA™ Version 1 Release 3 will be withdrawn from marketing effective December 31, 2001, and its service will be discontinued effective December 31, 2002.

CICS VSAM Recovery: IBM plans to make a new version of CICS VSAM Recovery (CICSVR) available soon. Specific availability dates, ordering information, and terms and conditions will be provided when the product is announced.

CICSVR is designed to be an easy to use VSAM recovery utility which can be used to recover VSAM data sets which are lost or damaged. CICS or batch VSAM data sets can be recovered.
CICSVR will have VSAM batch logging for VSAM data. Changes made to VSAM data sets by batch applications can be logged to a z/OS or OS/390 log stream. CICSVR can use the log records to help recover the VSAM data.
Change accumulation processing will be available. Forward recovery log records can be consolidated into change accumulation data sets. CICSVR can use change accumulation data sets to help speed up forward recovery.
Complete forward recovery automation will be possible when the VSAM data set was backed up by DFSMShsm™ and/or DFSMSdss™.
VSAM Data Set selection filters on CICSVR PDF panels and Disaster/Recovery functions are two customer requirements that help enhance function and improve usability.

Technical Information

Specified Operating Environment

Hardware Requirements

Processors: The basic requirement is for a processor that supports the prerequisite operating system and has sufficient processor storage to meet the requirements of the operating system, CICS TS V2, the application programs, the access methods, and all other software being run.

This includes the IBM zSeries 900.

Virtual Storage: Requirements for virtual storage for the product with Java and enterprise beans are included in the Performance Guide.

Parallel Sysplex Support: A Parallel Sysplex environment is required by each of the data-sharing facilities supported by CICS, and by the MVS system logger's log stream merging facility. This requires one or more coupling facilities with their associated coupling links installed, an IBM Sysplex Timer^® to provide a common external time source, and sufficient DASD paths to support the number of central processor complexes (CPCs) in the sysplex. The DASD paths can be provided either by DASD controllers with enough paths to dedicate one to each CPC in the sysplex, or by an ESCON^® director to provide the paths.

CICS support for data sharing can be used to access data in IMS databases, DB2 databases, VSAM data sets, CICS temporary storage, coupling facility data tables, or named counters.

Workstation Components: For the WebSphere Application Server, Advanced Single Server Edition V4.0 and the Information Center, a workstation is required capable of running Windows NT or Windows 2000.

Katakana Terminal Devices: Because CICS has to issue certain messages in mixed-case, the product is not supported with displays or terminal emulators that are restricted to the single-byte character set (SBCS) Katakana part of code page 930.

Software Requirements

Note that the Program Directory (GI10-2543) will normally contain the latest level of information on software requirements, particularly concerning service levels of supported products.

Operating environment:

The minimum required level of operating system for CICS Transaction Server for z/OS Version 2 Release 2 is OS/390 (5647-A01) Version 2 Release 10. z/OS (5694-A01) at all release levels is also supported. Note that the product will not initialize unless the minimum prerequisite level of operating system is installed.
OS/390 APAR PQ44884 (PTF UQ50735) is required for OS/390 V2.10.
For system-managed coupling facility structure duplexing, z/OS V1.2 is required, with an enabling PTF — refer to z/OS information.
Note that the Language Environment library SCEERUN must be available to CICS during CICS initialization, by inclusion in either the STEPLIB concatenation or the LNKLIST. Language Environment services are used by a number of CICS functions.
For Java application programs or for support of enterprise beans with CICS TS V2.2, the IBM Developer Kit for OS/390, Java 2 Technology Edition, V1.3.1 (5655-D35), known as the persistent, reusable JVM, is required.
- The persistent, reusable JVM is available, at no charge, on tape or by download from:
Service updates to the operating system are required in order to run the persistent, reusable JVM. The required PTFs are listed at:

CICS TS V2.2 supports Java program objects. These are Java applications that have been compiled using the VisualAge for Java Enterprise Toolkit for OS/390 (ET/390) byte-code binder (sometimes called high-performance compiler for Java). However, for restrictions, refer to the Compatibility section.

JNDI support for enterprise beans requires either an LDAP server, such as the LDAP server provided in SecureWay Security Server and licensed as part of the base z/OS or OS/390 operating system, or a COSNaming server. If a COSNaming server is required, WebSphere Application Server, Advanced Edition V3.5, or later, may be used. (Note that the shipped WebSphere Application Server, Advanced Single Server Edition V4.0 is not recommended for this function in production use; it does not support object persistence when recycling the server.)

Compatibility

Changed Behavior of EXEC CICS SIGNON/SIGNOFF: In levels of CICS Transaction Server prior to Version 2.1, an EXEC CICS SIGNON or SIGNOFF command modified the user ID and security characteristics of the transaction issuing the command, as well as the transaction's terminal. However (as documented in the CICS Application Programming Reference), this way of handling SIGNON in a running transaction can lead to unpredictable behavior. Therefore, from CICS TS V2.1, this behavior has been changed to apply only to the terminal and not the currently executing transaction. A temporary migration aid is provided to allow customers who depend on the old behavior to restore it. For full details, refer to the CICS Transaction Server for z/OS Migration Guide . Note that: (a) this aid will be removed in a future release ; (b) should problems be encountered due to the potential inconsistencies in the old behavior, no action would be taken by IBM to correct these problems.

Java Levels: CICS TS V2.2 does not support JVM mode programs at levels of Java earlier than the IBM Developer Kit for OS/390, Java 2 Technology Edition, V1.3. Any Java programs written for use with CICS TS V1.3 using a Java 1.1 JVM must be migrated to Java 2. For information about Java application migration issues, refer to the Web site of Sun Microsystems, Inc., at:

http://java.sun.com/j2se/1.3/compatibility.html

To avoid problems with deprecated APIs, all new Java applications for CICS TS V2 should be developed using an application development environment that supports Java 2 at the SDK 1.3 level. VisualAge for Java V3.5 or V4.0 can be used. Note that they support the SDK 1.2 level, but applications developed using them can be deployed into a SDK 1.3 environment. WebSphere Studio Application Developer supports development at the SDK 1.3 level. Note also that enterprise beans developed using VisualAge for Java V3.5 or V4.0, which support the EJB 1.0 specification, need to be migrated to the EJB 1.1 specification level. This may be done using the Application Assembly Tool (AAT) supplied with CICS TS V2.2. Enterprise beans developed using WebSphere Studio Application Developer support the EJB 1.1 specification.

CICS Programs Running under the JVM: A JVM program cannot link, either directly or indirectly, to another JVM program in the same CICS region. The reason for this restriction is that CICS JVM programs run in separate, isolated JVMs as separate UNIX^® System Services (USS) processes, and USS does not allow multiple processes to run concurrently on the same TCB.

Support for Java Program Objects: Java program objects are programs compiled with the VisualAge for Java Enterprise Toolkit for OS/390 (ET/390) byte-code binder (they are compiled with the hpj command, and are sometimes referred to as compiled Java programs or as HPJ programs). In CICS TS V2.2 it is recommended that all Java programs should be run in JVM mode, rather than as Java program objects. However, to ease migration from CICS TS V1.3, CICS TS V2.2 continues to support Java program objects, which can run with or without the HOTPOOL option, except that:

IIOP applications must execute in JVM mode
Enterprise beans must execute in JVM mode
Java applications that use the CCF client interface must execute in JVM mode

If a Java program object, developed for CICS TS V1.3, that has been migrated to run in CICS TS V2 requires modification, it is strongly recommended that it be recompiled for Java 2 and run in JVM mode. If this is not possible for some reason, the Java program object can be rebuilt as for CICS TS V1.3 using appropriate application development tooling. Note that users of VisualAge for Java V3.0.2 should migrate to VisualAge for Java V3.5 or later.

Support for both IIOP and non-IIOP Java program objects will be continued in CICS Transaction Server for OS/390 Version 1 Release 3 throughout its lifetime.

CORBA Support: GenericFactory IOR files are now created during the installation of CICS resources, removing the need for the GenFacIOR utility. Note that IIOP applications are supported in JVM mode only. The VisualAge for Java Enterprise ToolKit for OS/390 bytecode binder cannot be used with IIOP applications.

Java Applications Used with the CICS Connector for CICS TS: Java applications compiled on a distributed platform for use with the CICS Transaction Gateway may be used with the CICS Connector for CICS TS in CICS TS V2.2 without recompilation; unlike the position with CICS TS V2.1, references to applids do not need to be changed to sysids.

File Control User Exits: Changes to function shipping of file control requests have affected the invocation of file control user exits. The EXEC-level exits XFCREQ and XFCREQC are now invoked only in the region where the file control command was originally issued, not in the file-owning region (FOR). A new global user exit, XFCFRIN, is introduced. This new exit is a domain level exit and will be invoked on entry to the file control component (for example, in the FOR). This exit may:

Bypass file control processing
Specify a new SYSID to enable the request to be shipped to a remote region

Destination Control Table: The removal of run-time support for the destination control table (DCT) has made the DCT system initialization parameter obsolete.

Compiler Support: For compiler support, refer to the Software Requirements section.

CICSPlex SM: The CICSPlex System Manager element of CICS TS V2 does not support the following CICS products that were supported by previous levels of CICSPlex SM:

CICS/MVS^® Version 2.1.2 (5665-403)
CICS/ESA Version 3.3 (5685-083)
CICS/VSE^® Version 2 (any release) (5686-026)
CICS Transaction Server for VSE/ESA™ Version 1 (5648-054)
CICS for OS/2 Version 2.0.1 (5648-036)

For CICSPlex SM support of these CICS products, a CMAS at an appropriate lower level may be used. Normally all communicating CMAS should be at the same level, however, the following products may be controlled from the CICSPlex SM element of this product through an appropriate lower level of CMAS:

CICS/MVS Version 2.1.2 (5665-403)
CICS/ESA Version 3.3 (5685-083)
CICS for OS/2 Version 2.0.1 (5648-036)

CICS TS V2.2 will be the last level of CICS TS V2 which includes CICSPlex SM Agent support for CICS Transaction Server for OS/2 Version 4.1 (5622-808, due for discontinuance of service January 31, 2003).

RODM: As previously announced, the function of CICSPlex SM to populate CICS resource existence and minimal state data into the Resource Object Data Manager (RODM) component of NetView is removed from CICSPlex SM in CICS TS V2.2.

Remote MAS Agents: Support has been removed in CICS TS V2.2 for remote MAS agents for CICS on the z/OS or OS/390 platform.

Migration: To convert the CICSPlex SM Web User Interface server to CICS TS V2.2, it is necessary to migrate to the new level the MAS that acts as the Web User Interface server, using the normal MAS migration procedures; to upgrade the Web User Interface CSD group; and to migrate the contents of the Web User Interface server repository (EYUWREP) to a new data set, using the repository export and import functions.

Performance Considerations

Traditional Procedural Language Workloads: Comparisons with CICS TS V1.3, using an IBM internal benchmark, show that CICS TS V2.2 has equivalent performance characteristics in terms of Internal Transaction Rate (ITR).

IIOP Workloads: The support for inbound IIOP with Java program objects (compiled with the hpj command) has been removed with CICS TS V2. IIOP applications are supported in JVM mode only. The VisualAge for Java, Enterprise ToolKit for OS/390 bytecode binder cannot be used for IIOP applications. Although these IIOP applications in CICS TS V2.2 must run in JVM mode rather than as Java program objects, the performance is similar in terms of CPU costs and response time to that achieved for the same applications in CICS TS V1.3.

CICS Support for the Persistent, Reusable JVM: CICS TS V2.2 exploits the enhancements in the persistent, reusable JVM, at its latest level. The CICS support enables serial reuse of pre-initialized JVMs which, together with new garbage collection, provides significant performance improvements over the previous JVM. In the general availability level, it is expected that the performance of applications in this new environment will be similar to, if not better than, that of Java program objects (compiled with the hpj command) in CICS TS V1.3. Performance will continue to be improved throughout the timeframe to the next release.

CICS EJB Support: CICS TS V2.2 supports EJB session beans. The performance in this environment will be dependent on many factors relating to the application design, including the transactional qualities, the implicit services used by the enterprise bean, and adherence to the EJB programming specification. Although CICS TS V2.2 is recommended as capable of use in high-volume production, care will be necessary with regard to capacity planning guidance.

Publications

Publications Overview: In CICS TS V2, there has been a move away from the traditional printed books as the default deliverable to a new concept: the primary source of user information is a new CICS Information Center with a graphical user interface, delivered with the product on a CD-ROM. This HTML-based Information Center runs inside a Web browser, and provides various alternative means of accessing the information within it. The objective of the Information Center is to make it easy for users to retrieve the information they need to perform specific CICS tasks.

At the heart of the Information Center is an HTML representation of the total CICS library (unlicensed books). Within the graphical user interface, the key documentation can be accessed via three main classes: tasks, concepts , and reference , each separately selectable. On selecting a class, the categories for that class are displayed in the navigation panel. Each of these can be expanded into a hierarchical navigation tree of topics that in turn point to the detailed information.

The Information Center can be run from the CD-ROM or can be installed onto a workstation or Web server. It runs on Windows NT or Windows 2000. Note the requirements for a browser suitable for use with the Information Center, in the Software Requirements section.

A major new focus of the documentation in CICS TS V2.2 is the implementation of EJB technology in the CICS environment. A new piece of documentation entitled "Java Applications in CICS" is the cornerstone of this information, and has been structured to reflect the tasks required to use this new technology.

The Information Center includes a powerful search capability based on IBM's NetQuestion technology. Search results can be saved for future reference.

In addition to the new methods of accessing the CICS documentation, the Information Center provides the more traditional alternative of a complete library listing of the books (detailed below), which can be viewed in both HTML and PDF formats. The latter also provides the capability to print either the whole book or some of the pages in hardcopy at a printer, using Adobe Acrobat.

One copy of the CICS Information Center CD-ROM is automatically shipped as part of the product. Further copies can be ordered, at no additional charge, by specifying the following feature:

                                                  Feature

The Information Center (without the licensed publications, which are shipped only on the Information Center CD-ROM) may also be downloaded over the Internet, from:

http://www.ibm.com/software/ts/cics/library/

The navigation frames, help information, and home information of the Information Center are translated to French, German, and Korean; these translations are included on the one common CD-ROM.

Printed Publications: In addition to the softcopy information in the Information Center, the following printed documentation is delivered as hardcopy with the product. Note that order numbers have changed from those applicable with CICS TS V2.1.
