Depends on what you consider to be 'real' production issues. We get pages
for production and development, for things that really should be planned
change control, for idiot user stuff, as well as the regular db/listener
down, ora-0600 and the other standard stuff.
With most of the applications being developed in-house by folks that don't
really know anything about how Oracle really works, probably 60% is
fire-fighting. It's a lot better than it used to be however... We had a
reorg three years ago that split the then-DBA group into two sides -
Plan/Build, and Run. The Run folks were solely responsible for the pager.
Consequently, all of the Run folks quit right after I came on staff. So,
for 6 months or so it was me and two Sybase guys who were hired shortly
after me and did the crash-course route into Oracle. That was brutal.

Please respond to
ORACLE-L
Are those pages real production issues?
How much is fire fighting work?

We have 7 DBAs. 105 production databases (97 24x7), ranging from 2 GB OLTP
to 800 GB data warehouses. 395 devl/alpha/beta databases ranging in size
from very small (1 GB) to production-sized. About 1/3 of the production
databases have at least 1 (usually more) development effort going on at any
given time.
Most of our time (lives?) is spent just keeping things up and running. The
on-call guy averages between 50 to 100 pages per week (record is in the
230-range). Tuning and testing new stuff is fairly uncommon - as we have
time.

Please respond to
ORACLE-L
You are the first reply out of at least 20 (public and private) who has a
larger ratio than we do. The average seems to be somewhere around 20 so
far.
As many have pointed out, there are other factors to be considered if
you're
trying to measure the DBA's workload. I'm not trying to be that precise
though. The DB to DBA ratio is close enough for me.
BTW in case anyone is interested we have 2 DBAs managing 66 databases. 25
are dev/test. 41 are production. Of the 41, 39 are 24x7, 6 are over 100g,
one is over 1000g. These #'s are more accurate that what I reported off the
top of my head to a few in private.
