Running a regression test and received a S338 Reason Code 2390001 abend when using a //JOBLIB DD pointing to SYS1.SYSPPDSM.HTF1.PDSMAN.PDSMLINK.
The correct CA PDSMAN address space is not active.
On the system where the S338 occurs there needs to be a CA PDSMAN started task that is running with the //JOBLIB DD specified in the $DEMO job.
//JOBLIB DD DISP=SHR,DSN=SYS1.SYSPPDSM.PDSMAN.PDSMLINK
Since the $DEMO job did not fail with 'data set not found', the //JOBLIB DD data set MUST in the catalog, however, there is no CA PDSMAN started task using that data set
(from LINKLIST or a JOBLIB/STEPLB).
