Error ORA-20782 while deleting Golden Gate User

While dropping GoldenGate replicated user, I got an error.  Details are given below.

SQL> select distinct owner

     from dba_segments

     where owner in (select username

                from dba_users

                where default_tablespace not in ('SYSTEM','SYSAUX')

                ) ;

OWNER

GGTEST

drop user GGTEST cascade

ERROR at line 1:

ORA-00604: error occurred at recursive SQL level 2

ORA-20782: GoldenGate DDL Replication Error: Code :ORA-20782: Cannot DROP

object used in GoldenGate replication while trigger is enabled. Consult

GoldenGate documentation and/or call GoldenGate Technical Support if you wish to do so., error stack: ORA-06512: at line 231

ORA-06512: at line 957

Solution

Since I had run the ddl_setup.sql which created the DDL trigger for Golden Gate user schema.

So before deleting the Golden Gate replicated user, we need to drop the Golden Gate DDL trigger first.

SQL> SELECT * FROM DBA_TRIGGERS

WHERE OWNER='GGTEST';

no rows selected

SQL>  SELECT A.OBJ#, A.SYS_EVTS, B.NAME

FROM TRIGGER$ A,OBJ$ B

WHERE A.SYS_EVTS > 0

AND A.OBJ#=B.OBJ#

AND BASEOBJECT = 0;

      OBJ#   SYS_EVTS NAME
