L2 determined the CADB2091 was issued because a RENAME of a VIEW was requested.
As of this writing, a RENAME of a VIEW is not supported in DB2 V12.1 and V13.1.
Sample exits are provided by IBM for both 12.1 and 13.1 for the RACF security exit. Neither of them are set up to handle a RENAME of a VIEW.
