Description

IMS V7 Transaction Manager Enhancements

  • Continuous Availability
    • Rapid Network Reconnect (RNR)

      RNR improves system availability by allowing IMS TM to automatically reconnect terminal sessions following any kind of IMS failure and subsequent restart — reduces network reconnect time after IMS, MVS™, or VTAM® failure in a Sysplex environment.

    • IMS is Advanced ClusterProven

      IMS 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. The IMS solution satisfies the S/390® platform's technical criteria and has been registered to receive ClusterProven status. Specifically, IMS has obtained the status of Advanced ClusterProven by providing significant benefits above those inherent at the ClusterProven level. More information is available on the Web at:

    • Secondary Logical Unit Program (SLUP) cold Session Termination

      This enhancement improves availability by providing a command that allows a SLUP or FINANCE type session status to be reset to a "cold" state.

    • VTAM Generic Resource (VGR) Enhancement

      The installation can choose to have VTAM, instead of IMS, manage the generic resource affinity. This means that when any session outage occurs, whether a CPC, MVS, VTAM, or IMS failure, a new terminal session can be immediately established with any available IMS system. This function is also available for Version 6 through the service process.

  • Performance/Capacity/Scalability Enhancements
    • Multiple Systems Coupling (MSC) Descriptor Limit

      The MSC descriptor limit of 50 records per descriptor is removed.

    • Queue Space Exit

      This performance enhancement informs the Queue Space Notification user exit routine of a stopped destination. By notifying the exit routine that a destination is stopped, stacked messages can be prevented — system resources are not tied up with undeliverable messages and system availability is enhanced.

    • Suppress 3270 Negative Response

      Performance and system availability are enhanced by the addition of a new execution option for suppressing the SNA exception response that is normally associated the SNA protocols used with SLU2 input error conditions.

    • Spool Enhancement

      I/O Spool performance is improved and auto scheduling prints of data sets is enabled.

  • Systems Management/Usability
    • IMS Connect

      IMS Connect, a new separately-priced feature of IMS V7, provides enhanced IMS TCP/IP support. Enhancements include SMP installability, serviceability, usability, and improved performance in TCP/IP access to IMS. Future enhancements to IMS TCP/IP support will only be provided through the IMS V7 Connect feature.

    • IMS is certified Tivoli Ready.

      Tivoli Ready products are certified for integration with Tivoli management software. These products provide instant integration with Tivoli software, and they provide the power to immediately manage new additions to an IT environment. IMS management by Tivoli will be available in the Tivoli Manager for OS/390 March, 2000. For more information on Tivoli and Tivoli Ready products, see the Tivoli Web site at:

    • Associated Printer

      Usability and availability in a shared queues environment are both improved with the addition of the associated printer function. Now, by enabling autologon to a printer, enqueued messages from a backend application can be delivered to the associated front end printer.

    • Extended Terminal Option (ETO) Enhancement

      ETO is enhanced to improve autologon and printer support, reducing the need for operator intervention and monitoring.

    • Resource Access Control Facility (RACF®) PassTicket

      This enhancement allows the terminal/system entering the /SIGN ON command with a PassTicket (instead of a password) to specify the application name used in the creation of the PassTicket.

    • USERID Clarification

      The USERID clarification enhancement provides a way for application programs and user exits to determine the content of a USERID field. The content could be a RACF USERID, an LTERM name, a PSB name, blanks, binary zeros, or some other value.

    • TM Serviceability

      The TM Serviceability Enhancements, which make it easier to maintain and debug an IMS TM system, include:

      • The ability to determine if a non-base LU is active by using the DISPLAY APPC command
      • The ability to determine the APPC/MVS level in use
      • Improved diagnostics for APPC/OTMA User Message Control Error Exit — Type 6701 records are now logged
      • Improved diagnostics for APPC calls
      • Improved diagnostics for CQS call errors — New trace records are created
    • Message Requeuer (MRQ) compatibility

      This item ensures compatibility to the IMS Message Requeuer tool for all supported versions of IMS including Version 7.

    • MSC Exit Enhancements

      Three MSC exits (Input Message Routing, Link Receive, and Program Routing) are combined into a single exit routine for ease of coding and maintenance. This provides a consistent set of routing capabilities across all exit entry points and functions of the new exit module. MSC routing exit serviceability now logs routing errors and footprints in the message to indicate which exits re-routed the message.

    • Deferred Access Control Block (ACB) Open

      This enhancement provides the option of delaying the queuing of VTAM logon requests until IMS is ready to start accepting logons. Use of this function can prevent time outs.

    • Specifying CPLOG as an IMS Execution Parameter

      This function improves system availability by allowing users to change the number of log records produced between system checkpoints without the requirement of a system generation. Users can specify the number of log records between system checkpoints using the CPLOG execution parameter. The CPLOG value can be changed via the CHANGE command.

    • IMS External Subsystem Attach Facility (ESAF) Deadlock SNAP Trace Records

      This functions provides diagnostic information for identifying the source of an External Subsystem detected deadlock condition.

    • IMS ESAF Trace Enhancement

      This function enhances diagnostic information for the IMS External Subsystem Attach Facility. Trace records are now written after an event, such as signon, occurs. To accommodate Sysplex tracing, trace entry sizes are increased to 16 words. New and modified trace records provide additional information to facilitate the diagnosis of ESAF problems.

    • Displaying the IMS System Parameters

      This usability enhancement displays to the system console and to the job log the various parameters used in the initialization of an IMS control region.

    • Base Primitive Environment (BPE) Enhancements

      BPE enhancements provide command support for BPE to allow IMS components built using BPE services to define their own commands and command processing routines. Diagnostics are improved by the addition of trace table commands. Availability is enhanced with the addition of USEREXIT commands that allow users to update exits without restarting the address space.

    • Common Queue Server (CQS) Enhancements

      CQS is enhanced to allow multiple clients (for example, IMS) to connect to a structure through a single CQS. Additional enhancements allow a client to get more information about the Cold Queue, request information that was previously only available to user exits, and control the time stamp used by CQS to compute message age for a particular object.

    • Installation Verification Program (IVP) Enhancements

      The Install/IVP panels are changed to have the same look and feel as panels for other IBM products. Support for Data Facility Storage Management Facility (DFSMS™) constructs is added to make installation easier for sites that use SMS-managed volumes.

    • Open Transaction Manager Access (OTMA) Callable Interface

      The OTMA Callable Interface function improves IMS usability by providing a high-level interface for access to IMS applications from other OS/390 subsystems. It presents an API to application programs to enable access and execution of IMS transactions through IMS OTMA facilities. With this simple and easy-to-use interface, the invoker of the APIs can submit a transaction or command to IMS from within the OS/390 environment without the necessity of understanding the technical protocols of the MVS Cross Coupling Facility (XCF) or IMS OTMA. This function is available for IMS V6 through the service process.

The description of IMS V7 Database Manager enhancements is continued in the Supplemental Information section.

Description (Continued)

IMS V7 Database Manager Enhancements

  • Continuous Availability
    • Online Recovery Service (ORS)

      ORS, a new separately priced feature for IMS, provides database recovery processing in an online, IMS environment. A command initiates database recovery and substantially improves recovery time. Multiple full function database data sets and Fast Path areas can be recovered simultaneously in a single pass of the IMS log data sets.

    • IMS is Advanced ClusterProven

      IMS 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. The IMS solution satisfies the S/390 platform's technical criteria and has been registered to receive ClusterProven status. Specifically, IMS has obtained the status of Advanced ClusterProven by providing significant benefits above those inherent at the ClusterProven level. More information is available on the Web at:

    • Database Recovery Control (DBRC) Facility's Recovery Control (RECON) Upgrade/Coexistence

      System performance is improved by allowing users to upgrade the RECON from IMS V6 to IMS V7 without stopping active subsystems.

  • Performance/Capacity/Scalability Enhancements
    • High Availability Large Databases (HALDB)

      The HALDB function delivers enhancements to capacity, availability, manageability, and usability by enabling partitioning for full function IMS DB databases. HALDB supports as many as 1,001 partitions. A single HALDB partition has the capacity of an entire full function IMS DB database from earlier releases of IMS. HALDB improves database availability because multiple partitions decrease the amount of data unavailable if a partition fails or is taken offline. HALDB partitions can be processed in parallel, greatly reducing the total time required for batch workload or utility processing. Reorganized HALDBs are immediately usable after image copies are created because Prefix Resolution or Prefix Update utility processing is no longer required. A series of ISPF panels with imbedded help screens provide an interface for creating and migrating databases.

    • Large RECON Record Support

      System performance is enhanced by providing an enhanced system of RECON record size warning messages. Users can tailor the issuance of the warnings to their operating environment.

    • Fiber Channel Connectivity (FICON™) support

      Ficon support significantly improves I/O performance. This function is also available for IMS V6 through the service process.

    • ACB Enhancements

      ACB generation is changed to avoid unnecessary automatic rebuilding of PSBs when DMBs are rebuilt. The maximum number of SENSEGs and PCBs allowed in a PSB is increased.

  • Systems Management/Usability
    • IMS is certified Tivoli Ready.

      Tivoli Ready products are certified for integration with Tivoli management software. These products provide instant integration with Tivoli software, and they provide the power to immediately manage new additions to an IT environment. IMS management by Tivoli will be available in Tivoli Manager for OS/390 March, 2000. For more information on Tivoli and Tivoli Ready products, see the Tivoli Web site at:

    • IMS ESAF Deadlock SNAP Trace Records

      This function improves diagnostic information for identifying the source of a DB2® deadlock condition.

    • IMS ESAF Trace Enhancement

      This function enhances diagnostic information for the IMS ESAF. Trace records are now written after an event, such as signon, occurs. To accommodate Sysplex tracing, trace entry sizes are increased to 16 words. New and modified trace records provide additional information to facilitate the diagnosis of ESAF problems.

    • Displaying the IMS System Parameters

      This usability enhancement displays to the system console and to the job log the various parameters used in the initialization of an IMS control region.

    • IVP Enhancements

      The Install/IVP panels are changed to have the same look and feel as panels for other IBM products. Support for DFSMS constructs is added to make installation easier for sites that use SMS-managed volumes.

    • Specifying CPLOG as an IMS Execution Parameter

      This function improves system availability by allowing users to change the number of log records produced between system checkpoints without requiring a system generation. Users can specify the number of log records between system checkpoints using the CPLOG execution parameter. The CPLOG value can be changed via the CHANGE command.

    • Remote Site Recovery Migration/Coexistence support

      This function allows users of Remote Site Recovery to migrate to IMS V7, while maintaining disaster recovery capability.

    • RECON Loss Notification

      Systems management and recovery can be automated with the addition of a new message that detects a RECON data-set loss and lists the names of the subsystems using the failed RECON data set.

    • DBRC Serviceability

      Improved diagnostic information in ABEND messages, and in trace records, and new diagnostic tools for use by IBM service personnel, enhance DBRC serviceability. The LIST.HISTORY command is enhanced to provide an at-a-glance timeline for each DBDS/Area.

    • DBRC Support for PROCOPT=L|LS

      Using DBRC, database integrity is protected by requiring an image copy of data sets immediately after the database is loaded. Also, full recovery using an image copy taken prior to a load is prevented.

    • DBRC Image Copy GENMAX

      System management is improved by no longer allowing DBRC to automatically increase the GENMAX value when a user takes more than the specified number of image copies during a specified recovery period.

    • Logger Area Changes

      Three changes to the logger area are introduced. In the logger, an option is added to enforce dual logging at all times. In batch backout, to reduce diagnostic time, the content of message DFS3294 is changed. The Batch Backout utility is enhanced to comply with the DBRC CHECK17 option.

    • Fast Path Enhancements
      • Multiple Area Data Sets (MADS) I/O timing

        This enhancement, which applies to MADS environments, provides relief to the "long busy" state situation associated with internal recovery processing by RAMAC® disk drives and slow recovery of non-RAMAC disk drives.

      • I/O Toleration

        I/O Toleration allows data to be buffered so that programs can continue to access and update data when miscellaneous timeouts and exceptional conditions are encountered by the RAMAC drives.

      • Fast Path Monitor

        The IMS Monitor is enhanced to provide monitoring of Fast Path resources. The monitoring capabilities for Full Function and Fast Path databases are also enhanced to support new constraints so that limitations can be placed on what is monitored.

      • Single Dependent Segments (SDEPs) Scan Expands Compressed Data

        This enhancement extends the current IMS compression capability to the Fast Path Scan utility so that compressed SDEP components can be processed in any environment.

    • Application Control Block Generation (ACBGEN) Time/Version for Data Entry Databases (DEDBs)

      An aid for system programmers in analyzing Fast Path database problems, the ACBGEN for Time/Version for DEDBs enhancement enables Timestamp and version information in the ACBs for DEDBs and MSDBs.

Open Blueprint

IMS™ V7 provides the hierarchical database function described in IBM's Open Blueprint®. It provides the Data Language I (DL/I) interface from IBM to facilitate open, distributed, multivendor interoperability.

IMS V7 Transaction Manager provides the set of services which include:

  • Transaction processing program execution
  • Security
  • Systems management
  • Transactional integrity
Its implementation is consistent with the Transaction Monitor function described in IBM's Open Blueprint. It provides the Information Management System (IMS) application program interface (API) from IBM to facilitate open, distributed, multivendor interoperability.

IMS V7 uses many of the Open Blueprint resource managers.

IMS V7 is written in High Level Assembler and PL/X.

Compatibility: IMS V7 is upwardly compatible from previous versions/releases, allowing existing applications and data to be used without change. Migration/Coexistence support is provided for IMS V5 and V6 with V7.

IMS V7 introduces a new combined MSC exit (DFSMSCE0). V7 is the last release to support the old MSC exits: Terminal Routing (DFSCMTR0), Input Message Routing (DFSNPRT0), Link Receive Routing ((DFSCMLR0/DFSCMLR1), or Program Routing (DFSCMPR0).

IMS V5 was the last release to support IMS Client Server Object Manager (CSobject). Customers currently using IMS CSobject support should migrate to use IMS Connect.

IMS V5 was the last release for which VTAM was optional for IMS TM. In IMS V6 and V7, VTAM is required for service changes.

IMS V5 was also the last release to support:

  • RECOVCTL option in DBRC
  • LINEGRP UNITYPE = 1050, 2260, 2265, 2770, 2980, 3741, 777 , and TWX
  • MSPLINK TYPE = BSC
  • TYPE UNITYPE = SLUTYPE4

RSR is the IMS strategic solution to customer remote site recovery requirements. Since IBM's Remote Recovery Data Facility (RRDF) has been withdrawn from marketing, IMS customers using RRDF may wish to consider migrating to RSR.

IMS V7 includes IRLM V2. IMS V5 is the last release to support IRLM V1 Release 5. Both IRLM versions provide shared update support for FP and Full Function databases for IMS V5 and IMS V6. All IMS systems sharing a database must use the same version of IRLM. For the number of OS/390 systems sharing a database to be greater than two, all IMS systems must be on IMS V5, or later, with IRLM V2 and the Coupling Facility.

OSAM buffer caching in the Coupling Facility requires that all IMS systems in the Sysplex be on IMS V6 or IMS V7.

Performance Considerations: IMS V7 provides High Availability Database (HALDB) support, which removes the current DL/I database size limitations--8GB for OSAM and 4GB for VSAM databases-- by allowing partitions and thus much larger DL/I databases.

Online Recovery Service (ORS) has made faster recovery for shared databases a reality by concurrently reading log data sets, enabling simultaneous recovery of multiple DBDSs and area recovery.

IMS V7 Monitor extends the current performance monitoring to include Fast Path DEDBs, MSDBs, EMH Queues, BALG, and IFP regions.

CQS enhancements support multiple IMS systems sharing a CQS address space in a recovery situation thus reducing system resource requirements.

More below-the-line 16M Common Storage Area usage is made available by moving modules and control blocks above the 16M line.

User Group Requirements: This announcement satisfies, or partially satisfies, the following requirements from one or more of the worldwide user group communities. Groups include Australasion SHARE/GUIDE (ASG), COMMON, COMMON Europe, Guide International, G.U.I.D.E.
