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...
Best thing to do is document
Chuck,
I've been convinced that rebuilding indexes is a waste of time.
In fact, it can cost you time, as rebuilding indexes can kill your
peformance while the indexes again seek their 'level'.
Check into at asktom.oracle.com. There's some good examples.
