When you run the UPGRADE function of the CSD utility program
DFHCSDUP, ensure that you manually upgrade any CICS-supplied definitions
that you have modified in earlier releases.
About this task
It is important to upgrade your modified definitions to
ensure that they are defined correctly with nondefault values for
attributes that are new. If you fail to upgrade modified definitions, CICS® assigns default values to
any new attributes, and these might be inappropriate for CICS-supplied
resource definitions.
Procedure
- If you are not sure whether your CSD contains any modified
CICS-supplied definitions, use the DFHCSDUP SCAN command to compare
the CICS-supplied resource definitions with any user-modified versions. The DFHCSDUP SCAN command searches for the CICS-supplied version
of a specified resource name of a specific resource type and compares
it with any other resource definition of the same name and type. DFHCSDUP
reports any differences it finds between the CICS-supplied definition
and a user-modified version. If you have copied and changed the name
of a CICS-supplied definition, the SCAN command enables you to specify
the changed name as an alias.
- The safest way to upgrade your definitions is to copy the
upgraded CICS-supplied definitions and reapply your modifications. This action is necessary because the UPGRADE command does not
operate on your own groups or on CICS groups
that you have copied.
- If the CICS region
uses CICSPlex® SM,
manually upgrade any of the dynamically created CICSPlex SM resource
definitions that you modified in your previous release, using the
equivalents in Version 5.2. The dynamically created resource definitions and their attributes
are in the following members of the SEYUSAMP sample library:
- EYU$CDEF contains the default resource definitions for a CMAS.
- EYU$MDEF contains the default resource definitions for a MAS.
- EYU$WDEF contains the default resource definitions for a WUI server.
