Though I have published a script for determining indexes that need to be rebuilt, and then rebuilding them, I have to say that this is almost never necessary.
Why are you rebuilding indexes? About the only reason for ever doing so is that the BLEVEL >= 5.
go to asktom.oracle.com, and do a search on 'index rebuild'.
Currently, the third article may be of interest.

Where can I find more detail info about "frequent index rebuilds can reduce your performance" ?
Thanks.

Seema - If you analyze in conjunction with rebuilds, you could track with the LAST_ANALYZED column in USER_INDEXES table. That is all I can think of. Why do you ask? Jared has spoken eloquently about how frequent index rebuilds can reduce your performance.
