To Take Export Of A Table To Multiple Directories In Oracle
To take Export of a table to Multiple Directories in Oracle
Create 2 directories:
SQL> create directory DIR as '/home/oracle/DIR1'; Directory created. SQL> create directory DIR2 as '/home/oracle/DIR2'; Directory created. SQL> grant all on directory DIR1 to public; Grant succeeded. SQL> grant all on directory DIR2 to public; Grant succeeded.
Note : make these physical directories on server level too.
E.g
mkdir -p /home/oracle/DIR1 mkdir -p /home/oracle/DIR2
Now take export with parallel option:
[oracle@test ~]$ expdp \'sys/Oracle1234@pdbtest as sysdba\' tables=testuser.abc directory=dir parallel=2 dumpfile=dir:test_%U.dmp, dir2:test_%U.dmp logfile=testtable1.log Export: Release 19.0.0.0.0 - Production on Sat Jul 9 18:12:34 2022 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle and/or its affiliates.

Now you can see the dump file has been created in multiple directories.
Dump file set for testuser.abc is:
/home/oracle/DIR1/test_01.dmp
/home/oracle/DIR2/test_01.dmp
If you wish to compress the size , then you can use compression=all in the expdp command.
For import also you can use the similar method.
[oracle@test ~]$ impdp \'sys/Oracle1234@pdbtest as sysdba\' tables=testuser.abc directory=dir parallel=2 dumpfile=dir:test_%U.dmp, dir2:test_%U.dmp logfile=testtable1.log table_exists_action=REPLACE Import: Release 19.0.0.0.0 - Production on Sat Jul 9 18:30:58 2022 Version 19.3.0.0.0 Copyright (c) 1982, 2019, Oracle and/or its affiliates.
