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

The MAXASSIZE in the BPXPRMxx was lower as the recommended 2147483647.
Changing this dynamically will not solve the problem.
Change the BPXPRMxx member and IPL.
If MAXASSIZE in the BPXPRMxx is already set to 2147483647, then it is necessary to check if the value of ASSIZEMAX is lower than the recommended value of 2147483647. If this is the case, it should be set to 2147483647.
If installing using CSM then it is necessary to set to this value the ASSIZEMAX of both the CSM userid and the technician userid. This is because during install processing CSM switches between the CSM userid and the technician userid.
Each user with an OMVS segment may have an ASSIZEMAX value, which overrides the system MAXASSIZE value. To find the value for userid involved, issue this unix command from that userid:
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.
