Question asked by visitor abha s joshi

ORA-01033: ORACLE initialization or shutdown in progress
Cause: An attempt was made to log on while Oracle is being started up or shutdown.
Action: Wait a few minutes. Then retry the operation.

It means exactly that - the database is starting up and not yet ready or it's shutting down and will not allow you to connect. (You won't get this if the listener isn't available.)

Schedule your export to occur either before the DB shuts down or several minutes after it starts up.

I have recently encountered the same issue. However, I have been quite patient with the Oracle service (approx 1 hour) and it does not seem to start up on its own

Fortunately I am only running a local test environment, but I would be pleased to find a solution and not having to re-install Oracle and configure it again.

I hope there is someone with a solution out there.
