Software prerequisites

The following software is the minimum release level that must be installed to enable this release of OAM:

Any currently supported release of DB2 for z/OS. See "DB2 Product Lifecycle" (Under "Technical Details") at: http://www.ibm.com/software/data/db2/zos/features.html for information on the currently supported versions of DB2 for z/OS.
If the OSREQ macro is invoked from a CICS transaction, then IBM CICS Transaction Server 2.2 or higher is required:
If the OSREQ macro is invoked from an IMS application, then one of the following is required
- IBM IMS/VS Version 2
- IBM IMS/ESA® Version 4 Database Manager

Software can be ordered as soon as you have determined which, if any, of the required components must be added or upgraded. Remember to request supporting documentation when you place the software order.

If you are adding significant new system software along with OAM, consider phasing the installations. Install and test one product at a time; then, when the system is stabilized, add another product. This approach simplifies error diagnosis by limiting the number of potential problem areas.
