Apparently I'm the in-house DBA for 5 servers (out of a total of 88 instances). Biggest database is around 300GB (so far) and growing.

There isn't an "official" DBA in this place and, like someone else already posted, my day-job is a developer but it's amazing how priorities change when something goes bang.

I'm trying to get them to hire a DBA (i.e. give me a new job) as 99% of the staff that currently "manage" the servers haven't got a clue.
