Rich,

I think you're crazy adding indexes SYS tables. I would *never* add anything to sys objects. What are you going to do the first time something goes wrong and you call Oracle support and you "mention" you added an index and they say - hey, you're on your own! Not to mention that when you perform an upgrade, that this index may either get lost or be in the way.

No, a totally bad idea.

If anything, I would copy the audit records to a local table in your schema, and then index that baby anyway I'd like. That way, the system objects are the way that Oracle inteneded them to be.

Just my 2 cents.

Hey,

Anyone have any advice on indexing SYS tables? Specifically, I've been experimenting with putting a reverse index on the TIMESTAMP# column of AUD$, since almost all of my queries against the AUD$ views end with "ORDER BY TIMESTAMP DESC". In 8.1.7.4.0 test DBs on HP/UX, the index -- created under a non-SYS DBA schema -- works great. I'm looking for pitfalls, but can't come up with any of my own...

TIA!
Rich
