Just installed CA Dynamic Capacity Intelligence (DCI) 1.5 0300 on an LPAR where no other CA Mainframe solutions are running. CA Common Services has been installed and CAIRIM started at IPL.
When the DCI Controller region is started, a S0C4 in UNKNOWN module is returned. The Controller region doesn't work and it must be cancelled.

ZDCLOGR contains the following error messages:

Verified that CAIRIM is running with a very old maintenance level.
Applied all the available maintenance for CAIRIM and the other CA Common Services functions that are applied. IPLed the LPAR, restarted DCI and the S0C4 abend no longer occurred.
