When starting CA 7 and it abends with a U0750 and also you will see the following error message just prior to abend:
CAL2I750E DDName IASAGENT not found
Release : 12.0, 12.1
This cause when the IAS subsystem is initializing to enable agent jobs and one of the required DD are not found in the CA 7 STC proc. The required DD statement for IAS are:
IASAGENT
IASCRYPT
IASCKPT
CA7AGNT
You will need to add the require DD and dataset to the CA 7 STC proc. In this case, it will be the IASAGENT DD.
If you are not using IAS, you will need to change the XPDEF statement in the init deck to XPDEF,AGENTJOB=NO
