After rolling a maintenance, the following error displayed when any product is invoked:
RC=106, RCODE=0133 DB2 SSID DB3C is not defined in the CA-DB2 PARMLIB.
Release : 18.0

The problem was caused by the wrong suffix being used. Using STATUS command user was able to see the wrong SETUP. Providing the correct suffix corrected the problem.
