With such a large # of databases to support, how do
you divide up the work? Does everyone administer all of the databases, or are
databases assigned to a DBA? How do you handle on-call?

Well, I'll add my $00.02 worth.
I have about 15 databases, more or less. It varies depending on
what's going on. Right now it's more. :)
They are on NT, Win2k, Solaris and Linux.
Sizes range from a few gig to 450 gig.
In addition, I own IT change control ( Oh joy ), and a
few other goodies

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
We're 5 DBA including the team leader.
We have 130 Oracle DB + 40 Sql Server 2000 + 6 DB2 mainframe.
And we're doing development (data modeling ) and supposed to be involved in
architecture now.
Also, you should take in account if it's production or development work.
Are you involved in data mode
Chuck,
That's not really a good measure. It really depends on
a number of things.
* number of users
* number of apps
* size of db's
* quality of apps ( some require more work than others )
* amount of new development
* lots more I can't think of at the moment...

Chuck,
I support 17 development, 2 production oracle databases, 3 DB2/MVS databases
and 1 SQL Server. A coworker supports only 1 application and that is in
UAT/Dev environment but it is a highly active application in the
multi-Terabyte range (UDB). We have external prod. support for some of our
A simple num of databases to DBA ratio is quite meaningless.
You need to take into consideration of at least the following:
o Size of the database, transaction volume. What kind of up time your
database
needs to provide.
o Complexity of the database and application which run on top of it.
Consider yourself lucky. We've got a 71:1 ratio here.
"Chuck Hamilton"
We currently have twenty-one databases, thirteen production and eight which are
either test or development. Of the thirteen production databases five need to be up
on a 24 X 7 basis; physics experiments and or accelerator monitoring depend on them.
Nine of the production databases are Oracl
On the Oracle side there's 2 of us (myself and one other) supporting 20
databases, so that makes us 10:1.
However, in addition to this there is also the IBM mainframe/Software AG
Adabas side where it is my privilege to support the 5 legacy database
environments by myself.

I think this is a slippery argument. It may appeal to managers but can
lead to bad decisions long-term. Does anyone remember years ago when
managers would measure COBOL programmers LOC (lines of code)? Just measure
how many lines of code each programmer writes each day and vola! you know

However, there are also DBAs who support each project. That would make the

Chuck,
At this location we have a total of 5 databases and 1 DBA. Time off
without an electronic teather is a thing of the past. My last location
was 4 production databases with 1 DBA and a backup DBA from the
development arena of 2 development databases and 1 DBA.
