I've recently recovered a Data Guard configuration. Simple setup that syncs from primary to standby using Data Guard.
Because it's been on-line for a sustained period, some logs are missing and I need to do a full export.
From what I understand, a full export using RMAN can be accomplished on a running primary as long as the archive logs are taken in the back up.
Is this correct? are there any caveats I should be aware of?
