Home -> Community -> Mailing Lists -> Oracle-L -> Why does it take so long to write archive logs
Hello everyone,
We have an 8.1.7.4 on HP-UX 11.0 OPS database that uses 200mb archive logs with 3 archive log destinations, the first destination is local to the machine which is mandatory, the second destination is a filesystem accessible via nfs which is optional and the third destination is a remote standby database accessible via a vpn which is also optional. We have 10 archive processes to take care of the writing of the archives. Both the local destination and nfs mounted filesystems are on a HP XP256 storage device.
This morning there was a process running that would update a table that is used for a catalog of parts. The process was producing archive logs, but the archives were taking around 10 minutes to write. During the process we would see the file created with the expected byte count of the file within the first minute, but the timestamp of the file would indicate access for the next ten minutes.
We have two other 8.1.7 databases that are setup in a similar manner (that are not OPS) that have 2 destinations, one local and the other being sent to a remote standy database. We are not seeing the same type of issue with the archive logs.
Can someone point me in the direction of either information or advice about why the archives may be taking so long to write?
Is it that we have 3 destinations and it waits until all 3 destinations are taken care of?
Why does the archive log file appear to be modified even though the byte count hasn't changed?
TIA,
