IMS V8 Software Prerequisites and Migration SPEs
- IMS V8 operates under OS/390 V2R10 configurations, or subsequent versions, releases and modification levels, including z/OS (5694-A01), unless otherwise stated, and requires the following minimum version, or release or modification levels:
- OS/390 V2R10 (5647-AQ1) with DFSMS (a base element of OS/390 V2R10)
- RACF (included in a separately orderable SecureWay Security Server feature of OS/390 V2R10), or equivalent, if security is used
- IBM High-level Assembler Toolkit (5696-234), a separately orderable feature of OS/390
- IMS V8 also operates in a virtual machine (VM) under control of OS/390 V2R10 and is intended for use in a customer program development, testing and non-XRF production environment with some restrictions.
- z/OS V1 R2 is required for IMS MSC Ficon CTC support.
- z/OS V1 R2 is required for Shared Queues/EMH CF Duplexing support and for System Managed Duplexing of VSO structures.
- z/OS V1R2 Communications Server Affinity enhancement can be optionally used with IMS V8 Sysplex Terminal Management for enhanced usability.
- z/OS V1R2 CF Duplexing is recommended, though not required, for IMS V8 Resource Manager and Coordinated Online Change.
- In order to take full advantage of the Coordinated Online Recovery, Sysplex Terminal Management, Single Image Operations Manager, and/or Sysplex Wide Resource Management, IMS on all the Sysplex systems involved should be on IMS V8.
- All systems involved in using APPC/OTMA Synchronous Shared Queues support need to be on IMS V8 and z/OS V1 R2 for its Multi-System Cascaded Transactions support. Resource Recovery Services must also be active on all these systems.
- IMS Java application support requiretheIBM Developer Kit for OS/390, Java 2 Technology Edition (5655-D35), with a special enhancement, referred to as the Persistent Reusable Java Virtual Machine (JVM). This is required for the IMS V8 Java Dependent Region support.
- JDBC access to IMS DB for DB2 Stored Procedures requires DB2 UDB for OS/390 and z/OS V7 (5675-DB2).
- JDBC access to IMS DB for CICS applications requires CICS Transaction Server for z/OS V2 (5697-E93).
- IMS/DB2 Coordinated Disaster Recovery Support requires the IMS V8 Remote Site Recovery (RSR) Record Level Tracking (RLT) feature.
