ORA-31633: unable to create master table SYS_EXPORT_SCHEMA_01

The following errors occur when exporting/importing through data pump:

 ORA-31626: job does not exist
 ORA-31633: unable to create master table "USERNAME.SYS_EXPORT_SCHEMA_01"
 ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
 ORA-06512: at "SYS.KUPV$FT", line 1048
 ORA-01031: insufficient privileges


To make sure user ‘USERNAME’ to have enough privileges to do import/export.

DataPump: UDE-00008 ORA-31626 ORA-39086

The following errors occur when exporting data by using DataPump:

UDE-00008: operation generated ORACLE error 31626
ORA-31626: job does not exist
ORA-39086: cannot retrieve job information
ORA-06512: at "SYS.DBMS_DATAPUMP", line 2772
ORA-06512: at "SYS.DBMS_DATAPUMP", line 3886
ORA-06512: at line 1

Check the log which shows exporting has been successful.

Master table "SYS"."SYS_EXPORT_SCHEMA_01" successfully loaded/unloaded
Dump file set for SYS.SYS_EXPORT_SCHEMA_01 is:
Job "SYS"."SYS_EXPORT_SCHEMA_01" successfully completed at 12:08:38

So it is a bug, and this error can be ignored.

Asmcmd Pwcopy With PRCD-1163 PRCR-1071 CRS-0245 ASMCMD-9453

After standby database rebuilt, then trying to copy database password file from primary to standby ASM disk, the below errors occurred:

ASMCMD> pwcopy --dbuniquename RACTEST '/tmp/orapwractest' '+DATA/RACTEST/orapwractest'
copying /tmp/orapwractest -> +DATA/RACTEST/orapwractest
PRCD-1163 : Failed to modify database RACTEST
PRCR-1071 : Failed to register or update resource ora.ractest.db
CRS-0245: User doesn't have enough privilege to perform the operation
ASMCMD-9453: failed to register password file as a CRS resource

The password file was copied to ASM diskgroup ‘+DATA’ successfully, but the configuring  of database failed .


Rerun the same command without “–dbuniquename RACTEST” option.

ASMCMD> pwcopy /tmp/orapwractest +DATA/RACTEST/orapwractest
copying /tmp/orapwractest -> +DATA/RACTEST/orapwractest

Then use ‘srvctl’ to re-configure database as user ‘oracle’ if needed:

$srvctl modify database -d RACTEST -pwfile '+DATA/RACTEST/orapwractest';

$srvctl config database -d RACTEST

Stream pool size is too small, and there is no more memory for stream pool to increase.


Increase streams_pool_size:

SQL> show parameter streams_pool_size

NAME              TYPE        VALUE
----------------- ----------- ---------
streams_pool_size big integer 20M

SQL> alter system set streams_pool_size=128M ;

If not enough memory available:

SQL>  alter system flush SHARED_POOL;
System altered.

-- OR 

SQL> alter system flush BUFFER_CACHE;
System altered.

SQL> alter system set streams_pool_size=128M ;

For AMM or ASMM, after data pump is complete, reset the parameter to leave system to manage this parameter again.

SQL> alter system reset streams_pool_size;
