A recently converted subsystem (RDSA) to a data sharing group with one member RDAA -
RDSA is now the DSG name.
RDSA and RDAA are both defined in SETUP00 (RDSA as group of RDAA as well) and added the RDAA member to APPLS.
Have this message when selecting a product from the home panel with SSID RDSA on the LPAR where the RDAA member is running.
Batch jobs are also failing with the same message.
Release : 20.0
Component : CA RC/Migrator for DB2 for z/OS
When converting the original member RDSA to a DSG, it was forgotten to remove the MVS system definitions from IEFSSN00.
Having removed the entries from IEFSSN00 the issue is resolved.
