EXPORT

I have investigated the cause of L1009 datapump export failure. The
following errors reported in export log file:

ORA-31626: job does not exist
ORA-31637: cannot create job exp_OPS$IHESS\SRVORACLEBATCH for user
OPS$IHESS\SRVORACLEBATCH
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT_INT", line 600
ORA-39080: failed to create queues "KUPC$C_1_20080611182005" and
"KUPC$S_1_20080611182005" for Data Pump job
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPC$QUE_INT", line 1580
ORA-04031: unable to allocate 56 bytes of shared memory ("streams
pool","unknown object","streams pool","fixed allocation callback")
--

expdp / directory=data_pump_dir dumpfile=schema_%SCH%.nightly_dmp
logfile=schema_%SCH%.log job_name=exp_%SCH1% schemas=%SCH1%
estimate=statistics flashback_time=\"to_timestamp('%ltime%','dd-mon-yy
hh24:mi:ss')\"

Here SCH will be replaced with Schema name(OPS$IHESS\SRVORACLEBATCH,
SYSTEM, VRS_SHR_OWNER). The export of these schemas got failed due to
unable to find the jobs which mentioned at job_name parameter. These
jobs
might not be created because insufficient or unable to allocate space in
shared memory at that time.

Please advice me
