CICS configurations

When you use CICS® Configuration Manager to work with resource definitions, rather than referring explicitly to the CSD file or the CICSPlex® SM context that contains the resource definitions, you refer to the name of a CICS configuration. A CICS configuration is a record in the CICS Configuration Manager repository that refers to a CSD file, a context, or an export file. Using CICS configurations:

You instruct CICS Configuration Manager to copy a resource definition between any combination of two CICS configurations. For example:
  • Two CSD files
  • A CSD file and a context
  • Two contexts in different data repositories
  • Two contexts in the same data repository

CICS Configuration Manager handles underlying differences between CICS configurations, using proven updating methods:
  • To update resource definitions stored in CSD files, CICS Configuration Manager uses one of the following methods, depending on the release of CICS Transaction Server for z/OS® that the CICS Configuration Manager server is running under:
    • CICS Transaction Server for z/OS V4.1, or earlier: CICS Configuration Manager uses the CICS-supplied DFHEDAP program
    • From CICS Transaction Server for z/OS V4.2: CICS Configuration Manager uses CICS system programming interface (SPI) commands
  • To update resource definitions stored in CICSPlex SM data repositories, CICS Configuration Manager uses the CICSPlex SM application programming interface (API).

CICS configurations as offline staging areas

The CSD file or context that a CICS configuration refers to does not need to be associated with an active CICS system. It may be merely a staging area for resource definition requests from application developers. These requests may be migrated, after approval, to active test CICS systems. In this way, CICS administrators can control the definition of resources across all CICS systems.
