Monitor data pump expdp export script

Question:  I need to monitor a data pump export job and I want to monitor the progress of the expdp command.  What are the ways to monitor a Oracle export job?

 

Answer:  The data pump logfile is the best way to monitor the progress on a data pump export, as data pump writes it's progress on a regular basis.

From the operating system prompt, run the expdp utility to export the job_user schema. The following listing shows both the export command and the export log output:

expdp system/password schemas=JOB_USER directory=EXPORT_DIR dumpfile=JOB_USER.dmp
logfile=expdpJOB_USER.log

You can also observe v$session_longops to monitor some parts of an Oracle export job.
 

select
   round(sofar/totalwork*100,2)  percent_completed, 
   v$session_longops.* 
from 
   v$session_longops 
where
   sofar <> totalwork 
order by
   target, 
   sid;
