Re: Rapid Log Switching

Rich,

Thanks - Brain didn't catch up with last post there.

John,

I recall Tanel Poder making some comments about "private threads" having space reserved in the log file - do you have a very large value for the 'transactions' parameter: which would require a lot of private threads, which possibly might pre-empt a lot of space in the logs then not use it. (10.2, 64Bit - private threads can take 128Kb each, and threads = ceil(transactions / 10)
