RE: commit rate

Edward - Take a look at STATSPACK. The summary report has a statistic labeled "Transactions", which I believe is what you want. Dennis Williams

Hi Edward,

   please list, correct me if I'm wrong

    I think may be the amount of "log_file_sync" could help you too. But I think you should substract
DBWR waits on this event.

    I also think that 'user commits' statistics is independent of group commits, this statistic is updated whenever a user issues a commit and group commits is just a way LGWR can write entries from log buffer to redo logs.
