Release : 15.0
Component : CCS390 - CA COMMON SERVICES FOR Z/OS
apar RO94642. This apar is for z/OS 2.3 support and will fix the s0c4 if upgrading to above z/OS 2.2
When intercepting mount messages on a z/OS 2.3 system, a S0C4 abend will
occur in the CA 1 message intercept routine when an IEF233A mount message
is issued. If DEFER is used or dynamic allocation, the mount message is
never issued and the job simply hangs.
