This section briefly describes the hardware and software that is required by IMS Version 9.

Related Reading: For the complete details about the hardware and software requirements and compatibility of IMS releases with versions of the operating system and associated products, see the following release planning guides:

• IMS Version 7: Release Planning Guide

• IMS Version 8: Release Planning Guide

• IMS Version 9: Release Planning Guide

Hardware

IMS Version 9 runs on all IBM processors that are capable of running z/OS System Product Version 1 Release 4 or later. IMS Version 9 can run on either 64-bit processors or 32-bit processors.

For all system libraries and working storage space, any device that is supported by the operating system is allowed.

For IMS database storage, any device that is supported by the operating system is allowed within the capabilities and restrictions of Basic Sequential Access Method (BSAM), Queued Sequential Access Method (QSAM), Overflow Sequential Access Method (OSAM), and Virtual Storage Access Method (VSAM).

Details about the DASD storage requirements for the following items are listed in IMS Version 9: Program Directory for Information Management System Transaction and Database Servers:

• SMP/E system entries

• SMP/E data sets

• Target libraries

• Distribution libraries

• Install process

• Optional machine-readable material

Software

IMS Version 9 operates in z/OS Version 1 Release 4 (or later) configurations and requires the following minimum version, release, or modification levels:

• z/OS Version 1 Release 4 (5694-A01)

  - DFSMS*

  - SMP/E*

  - JES2*

  - JES3*

  - TSO/E*

  Note

  * These items are base elements of the z/OS operating environment that cannot be ordered separately.

  
  

  - IBM High-Level Assembler Toolkit (5696-234), a separately orderable feature of z/OS

  - RACF® (available with the IBM SecureWay® Security Server for z/OS and OS/390 RACF product) or equivalent product, if security is used

  - ISPF Version 4 Release 2 (5655-042)

  - e-Network Communications Server for z/OS, if IMS Transaction Manager is used

• IRLM Version 2.1 or later (5655-DB2), if data sharing is used

IMS Version 9 also operates in a virtual machine (VM) under the control of z/OS Version 1 Release 4. This environment is intended for use in a program development, testing, and non-XRF production environment.

CICS Subsystems Supported

IMS DB Version 9 can be connected (using the IMS Database Resource Adapter) to the following systems:

IMS TM Version 9 can be connected (using the appropriate TM interface) to the following systems:

• CICS Transaction Server for z/OS Version 2.2 (5697-E93)

• CICS Transaction Server for OS/390 Version 1.3 (5655-147)

DB2 Subsystems Supported

IMS TM Version 9 can be connected to any of the following DB2 products:

• DB2 UDB for z/OS Version 8 (5625-DB2)

• DB2 for z/OS and OS/390 Version 7 (5675-DB2)
