ARCH wait on SENDREQ
Database version:10.2.0.4 on Redhat linux
We have configured physical standby.
One of the batches which runs daily took 5hrs 15 mins to complete, whereas it normally takes 15mins. In the AWR reports I noticed the wait event 'ARCH wait on SENDREQ' for the duration for which the batch ran.
I found the following info from Metalink.
"ARCH wait on SENDREQ" -- This wait event monitors the amount of time spent by all archiver processes to write the received redo data to disk as well as open and close the remote archived redo log files. This wait events can lead to a slow performance.
