When installing the CA Common Services components you can experience a problem with the APPLY of the Tomcat part. In CSM, or via the sample JCL.

The MAXASSIZE in the BPXPRMxx was lower as the recommended 2147483647.

If it's not allowed to have such large ASSIZEMAX, it would be possible to run with a smaller ASSIZE value starting at 524288000 (500Mb).
This will override the value that's currently set as MAXASSIZE in the BPXPRMxx member.
