LGWR strange behaviour during the performance test!

HesipesiOct 18 2013 — edited Oct 18 2013

Hi,

We are doing performance test on our new schema and during the test we see that this LGWR database process is always the highest resource taking process during the test.

I see that the Commit activity appears continiously on Grid Controller toghegher with System I/O.

I checked the Redo Logs and we have them in 5 groups each 200MB.

Any idea about what causes this? I guess the application is doing one commit after each statement, or?

Any comment about how can we improve this?

I wanted to attach the screenshot from the Grid Controller but it seems we can't do that on this Forum!

Thanks in advance for the help!
