In the process of upgrading R19 CA Database Management for DB2 for Z/OS suite to a new maintenance level the first job ssid0000 fails in step COMPRT in ssid0000: DB2 connection error $CTDIR LOCVER error. Request fail RC=00000008 RS=00000014.
In many previous cases with more than one PTXMAN running on different maintenance levels, Xmanager caused the problem because it was not running at the SAME maintenance level. Such a situation can cause unpredictable results like the : $CTDIR LOCVER error.
DB2 for Z/OS
The xmanager in use was already pointing to the updated CDBALOAD library. Customer has two PTXMAN's running one for current maintenance level and the other on the updated maintenance level pointing them to a different XMANID. The XSYS value was changed to XSYS=N on the updated PTXMAN level and was able to complete the ssid0000 job. Until the new maintenance level is installed in all environments this same setting should be maintained.
Stopping and Starting the Xmanager started task and changing the value of XSYS=Y to XSYS=N after making sure that the CDBALOAD library being used is the updated one often solves the problem.
