Re: Oracle Reports: Temporary indexes?

The chance of the indexes you require hurting an OLTP system is vanishingly small. I would strongly suggest that you benchmark the system without the indexes, and with the indexes, and see if having them makes a detectable difference.

You don't say what operating system and platform, or how much data, or how many Tx per hour, or how many indexes of what type, so it is hard to know for sure.

But as a general rule I'd strongly advise against building temporary indexes. I've never yet seen a need to do so.
