ORA-31626: job does not exist
ORA-31633: unable to create master table "SYSTEM.SYS_EXPORT_FULL_05"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT", line 1048
ORA-06502: PL/SQL: numeric or value error: character string buffer too small=============================================================
Note: - Master table for Data Pump job was not being created hence it was terminating the Data pump job at its initial startup. In above error we can see ORA-06502
that comes most of the time if we have not set streams_pool_size parameter value to enough
one but in my case it was sized enough set as below to perform Data Pump Operations.
NAME TYPE VALUE
------------------------------------ -------------------------------- ------------------------------
streams_pool_size big integer 128M
Further we decided to clear any data pump orphaned job
left in the database from earlier executions.

Terrible, it failed again with same error.
We then decided to re-load Data Pump packages even our Catalog status was in VALID state in database registry.
-- Decided to re-load data pump packages
1.Catproc.sql
SQL> @$ORACLE_HOME/rdbms/admin/catproc.sql
2.To recompile invalid objects, if any
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
Note :- you need to follow proper steps to run catproc.sql script in Oracle RAC database.
=============================================================
Tried to fire Data Pump Export job again but failed with same error…… L
รจ Tried to trace the data pump session to diagnose it in depth. You should try this step earlier than reloading data pump packages. We set below event tracing and fired Data Pump job again and it generated trace file for that point in time. Make sure you turn off the event after you are done with tracing.
Set event 6502 to trap ORA-6502 and dump a stack trace
SQL> alter system set events '6502 trace name errorstack level 3';
SQL> alter system set events 'sql_trace {process : pname = dw , pname =
dm} level=12';
After reviewing the trace file generated, we could see, there was a TRIGGER(MONITORING_DDL) which was causing our export job to fail at every attempt.
SQL> select owner, object_name, object_type, status from dba_objects where lower(object_name) like '%monitoring_ddl';
OWNER OBJECT_NAME OBJECT_TYPE STATUS
--------------- ------------------------------ ----------------------- -------
SYSTEM MONITORING_DDL TRIGGER VALID
SYSTEM MONITORING_DDL TABLE VALID
3 rows selected. -- We Disabled the Trigger..............
We decided to disable to trigger as it was preventing DDLs operations to be performed other than SYS and SYSTEM users.
SQL> alter trigger system.MONITORING_DDL disable;
Trigger altered.
Finally, tried to run Data Pump Export Job again and it went fine.
