utlrp error with ORA-04045: errors during recompilation/revalidation of GGUSER.DDLREPLICATION

CAUSE:
Goldent Gate DDL is enabled on database. Trigger sys.GGS_DDL_TRIGGER_BEFORE will be fired for utlrp, but the trigger is failed because some Golden Gate object is invalid.

Solution:
1. disable the trigger as sysdba
alter trigger sys.GGS_DDL_TRIGGER_BEFORE disable ;
2. run utlrp
@?/rdbms/admin/utlrp.sql
3. enable the trigger as sysdba
alter trigger sys.GGS_DDL_TRIGGER_BEFORE enable ;
