Hi Friends,

Can we take export backup of a production database when users are accessing same? When we import this export dump will there be any issues?

Please provide me a solution for this.

Thanks,
pavan

Yes, use "consistent=yes" and don't use SYS.
export is NOT a backup.

Yes if you didn't use "consistent=yes".

But you can also have problem during export as you must have undo segments enough to support the concurrent users activity.

Regards
Michel
