I followed the instructions at http://www.oracle-base.com/articles/10g/oracle-data-pump-10g.php to create a database export.
I used:
expdp scott/tiger@db10g full=Y directory=TEST_DIR dumpfile=DB10G.dmp logfile=expdpDB10G.log
to create the export. However I get this error message:
UDE-00008: operation generated ORACLE error 12154
ORA-01033: ORACLE initialization or shutdown in progress
How do I resolve this issue?
