Before you set up a CMAS

Check your initialization values, changes between releases, release level compatibility and maintenance you might need to apply to your system.

Check the considerations for setting up CMAS, described in Designing your CICSPlex SM environment.

Check the IEASYSxx member of SYS1.PARMLIB that you use for MVS initialization and make note of the initialization values that are referenced during installation. For details about the initialization values, see Noting IEASYSxx values for CICSPlex SM.

If you are converting your CICSPlex® SM system or systems from a previous release to CICSPlex SM for CICS® TS for z/OS®, Version 5.5, read the upgrading information for your level of CICSPlex SM.

A CICSPlex SM CMAS runs only in a CICS system at the same release level. For example, a CICS TS 5.5 CMAS runs only in a CICS TS 5.5 region. During startup, the CMAS checks the CICS release level and ends with message EYUXL0142 if the releases do not match. Managed CICS systems do not have the same restriction.

For details about applying corrective or preventive maintenance to CICSPlex SM, see Applying service to CICS Transaction Server for z/OS.

Note the information in CICSPlex SM address space (CMAS) about appropriate uses of a CMAS.
