  • manage the archive log file system so that even on the highest load of an errant program it doesn't fill up and freeze the db.
  • find enough space somewhere to keep the compressed archived logs until the next backup and make sure it doesn't blow up under the same conditions.
  • make sure the archiver works fine and doesn't let the db freeze while waiting for it.

and I can think of a few details more, mostly relevant to development and test dbs.
What do you reckon of this as a subject to talk about on a future meetup?
