Query v$session to see on what your export session is waiting for.

While this should NOT be the case, do any clues exist within alert_SID.log file?

SELECT * FROM V$SESS_IO WHERE SID = <Session_ID of exp>;

issue SQL above multiple times with brief pause between them
If exp session is doing "work", one or more columns will be increasing.
If returned value never change then session is "stuck" & waiting for some other session to release object/lock/latch

Or try to restart the server, or even the power station, who knows?
To know you have to investigate and the first step is to query v$session.

Sounds like SHUTDOWN ABORT is only way to clear out the log jam.

Dear Blackswan and Michel

As per your suggestion and moral support i shutdown the database with abort option and start it again. There is no errors in alertSID.log and my export started again. Many thanks for your late night support. It is 12:30 a.m. in india and still guys you supporting. Thanks a lot again.

Expected behaviour as some are waiting then can't halt by themselves.

By the way, "is not working" is not an Oracle error, so please ALWAYS copy and paste your SQL*Plus session.

I NEVER said that and won't say it before having the result of the investigation.
Now you lose the context and are no more able to know what happened and you can be sure it will happen in the future.
