GGATE ABBENDED: ORA-00308: Cannot Open Archived Log

Hi all!
Ok, so this is one of the most common issues for GGate administration. How to solve it? Easy thing.

First let’s understand what it means: It means the redologs don’t have the required information (assuming integrated) and you have already deleted archivelogs the extract needs. Why? Probably because you already backed up those archivelogs and they were not needed for the database anymore.

Unfortunately we don’t have any kind of ARCHIVELOG DELETION POLICY to guarantee extracts had already read it, like we have for Dataguard. So, what can we do?

Restore the missing archivelogs.

But first let’s confirm on the errors. Some examples:
