CICS Transaction Server for z/OS 4.1 detailed system requirements

Product documentation


The tables in this document contain the detailed system requirements (DSR) for the supported operating systems, hardware and software requirements, and other related information for CICS Transaction Server for z/OS (CICS TS) V4.1.


When installing CICS TS V4.1, review the
CICS TS V4.1 Program Directory for material and procedures associated with the installation of CICS TS. When upgrading to a new release of CICS, you should always review the Preventive Service Planning (PSP) information for the release of CICS you are installing.

IBM also recommends that you review the upgrading information when changing releases of CICS to determine if there are any known problems that you can avoid.

See Software developers supporting CICS TS V4.1 for a list of Independent Software Vendors (ISVs) that have indicated they support CICS TS V4.1.

CICS TS V4.1 Supported Operating System

z/OS z/OS V1.9 (5994-A01) or later is required. CICS TS V4.1 will not initialize in an environment with a lower level of operating system installed.
  • If used with z/OS V1.9, PTF UA34182 for APAR OA19565 is required.
  • Ensure that the PTFs for the following z/OS 1.9 APARs are applied: OA20352, OA20343, OA19958.
  • If used with WebSphere MQ for z/OS V6.0, then the PTFs for APARs PK38772 and PK42616 are required.

CICS TS V4.1 Hardware Requirements

  • The basic requirement is a processor that supports the prerequisite operating system and has sufficient processor storage to meet the requirements of the operating system, CICS TS V4.1, the application programs, the access methods, and all other software being run. The operating system requirement limits this to z/Architecture machines.
Parallel Sysplex support
  • 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.
  • 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.
System z cryptographic hardware
  • If you want to exploit the WS-Security capability, which relies upon the z/OS Integrated Cryptographic Services Facility (ICSF), then appropriate System z cryptographic hardware is required. For System z 800 and 900, this hardware is the Cryptographic Coprocessor Feature and the PCI Cryptographic Coprocessor. For System z 890, 990, z9 and z10, it is the CP Assist for Cryptographic Functions and the Crypto Express 2 coprocessor.
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 non-extended single-byte character set (SBCS) Katakana part of code page 930.

CICS TS V4.1 Software Requirements
Language Environment (LE)
  • IBM SDK for z/OS, Java 2 Technology Edition, V6, Service Refresh 7 (SR7) or IBM SDK for z/OS, Java 2 Technology Edition V6.0.1 (see APAR PM38397) is required if using Java application programs, enterprise beans, or the CICS Web services assistant. The IBM SDK for z/OS is available, without charge, on tape or by download from:
    Note: IBM 64-bit SDK for z/OS, Java 2 Technology Edition, V1.4 (5655-M30) is not supported. Also, IBM 31-bit SDK for z/OS, Java 2 Technology Edition, V5 (5655-N98) is not supported.
  • For developing Java programs, a suitable integrated development environment (IDE) is required, such as IBM Rational Developer for System z V7.5. A trial copy of Rational Developer for System z V7.5 is shipped with this release of CICS TS. This unsupported trial copy can be used to gain experience of the advantages of a fully functional mixed language application development environment at no additional charge. A Rational Developer for System z trial download Web site is available at:
  • For developing enterprise beans, one of the following IDEs is recommended: The packaging application (Application Server Toolkit) provided with WebSphere Application Server V6.0, or WebSphere Application Server V6.1 can also be used for the deployment of enterprise beans.

CICS Tools and Related Products The following IBM products can be used* with CICS TS V4.1:
*Ensure that the latest levels of service are applied to each IBM product listed. In some cases, the latest version of a product might be required to take advantage of new function in CICS TS V4.1.
COBOL, PL/I, C/C++, Java, and Assembler Compilers
Identity propagation
  • With the introduction of IBM z/OS V1.11, CICS TS V4.1 will support, by year end 2009, the forthcoming z/OS identity propagation capabilities that allow security identities operating in the distributed environment to be associated with security identities used on the server (z/OS user IDs). This enables CICS applications to participate in end-to-end security solutions, and therefore benefit from improved cross-platform accountability and auditing, providing an alternative to custom written identity mapping.

    For identity context propagation functions in CICS TS V4.1, z/OS V1.11 (5694-A01) is required, and also an enabling CICS PTF (the CICS APAR is not available to view yet, but the number will be PK83741 Functional enablement for support of distributed identities). For further details on IBM z/OS V1.11, refer to Software Announcement 209-029, dated February 24, 2009.
