RE: Need to Log on 2000 users

Sorry Munish, I misinterpreted your question. But Jared's suggestion is a good one. You can use orastack to set parameters to maximize memory use for your test database. And too, 128Gb sounds like a pretty large number for 2000 users!

Jeremiah,

Where do you get 128Gb?

For 2000 users that is ~65M per user, which seems like an excessive estimate.

While I probably wouldn't want to run 2k users on a single Windows server, I think you could do it for test purposes.

Use orastack to reduce the memory per thread to 500k, set small sort_area_size, etc. Don't see why not.
