Export datapump error in Exadata RAC

in Database Utilities (MOSC) 5 commentsAnswered ✓

I have 2 exadata servers (server1 and server2) on Linux. server1 is Oracle19c and server2 is Oracle12c. I have established network_link/db_link between server1 and server2. server1 is 7 db node rac setup.

Export dump files go to NFS mounted Data Domain storage, which is mounted on server1 (all 7 db nodes) with same mount options.

Mount parameters I am using are : rw,hard,intr,nolock,nfsvers=3,tcp,rsize=1048600,wsize=1048600,bg

Export command I am using from server1 is as follows. This should export data from server2 and create the dumpfile in Data Domain storage on server1.

expdp user1/pass1 full=n schemas=user1 directory=directory1 dumpfile=dumpfile_%U.dmp logfile=logfile.log parallel=16 cluster=n network_link=network_link_name

Howdy, Stranger!
