Re: gcs log flush sync

John,

I don't discount this as an idle wait. Basically you (LMS) are/is waiting for LGWR to flush the pending redo during CR fabrication. Without going too much in to details, you can turn off the behaviour by setting _cr_server_log_flush to false.

Are you looking for the details on this wait event or having a performance problem and suspecting the wait?
