Installed the most recent CA Common Services 15.0 with maintenance.

When I try to start ZMSHUB, the STC runs and immediately completes with a RC=0, but the STC does not keep on executing as an address space.

Is this its normal behavior ?

The hubnode.log file shows the following errors:

Improper definition of OMVS Segment for the userid under which the ZMSHUB task is running.

Look for following messages in joblog (SYSOUT) that may be an indicator of this problem:

 JVMJZBL2999T Setting current working dir to: ""
JVMJZBL2999W Could not set current directory to:


Release : 15.0


Have your security administrator review the security setting for the userid that the task is running under.

Have a look at the documented security setup...
Configure Message Service HUB for z/OS

Make certain that the userid has a valid OMVS segment defined and that the OMVS HOME Directory is defined and accessible to the id.
