CA Datacom/AD Version 15.0 Active Upgrade was successful but any subsequent attempt to access my CA product's data such as a DBUTLTY BACKUP of CA WORKLOAD AUTOMATION RESTART OPTION FOR Z/OS (aka CA-11) base 601 fails with:
The CA Datacom/AD 15.0 Multi-user (MUF) log shows...
CA Datacom/AD 15.0 Active Upgrade job INSTJCL(AXACTUPG) STEP2A assembly of the custom module DBSIDPR specified "FORCE_DSN_CXXNAME=YES".
With "FORCE_DSN_CXXNAME=YES", the CXXNAME is enforced and requires that every data set that Datacom opens has the CXXNAME as a DSN node.
With 'FORCE_DSN_CXXNAME=NO' the CXXNAME name is not enforced as a node in the DSN.
