too many archive logs
Date: Wed, 18 Mar 2009 04:11:33 -0700 (PDT)
I'm running 10.2.0.4 on solaris 10 (sparc 64).
I'm in archivelog mode with 3 groups of redo logs sized at 200M (at 100M I was getting checkpoint can't complete messages). I've got archive_lag_target set to 900. Watching the alert log all seems to be fine. However, when I go to /flash_recovery_area/SID/archivelog, there are thousands of archive files, mostly between 10 and 20 MB. For example, at 6:49 I see six 11MB archives. Some days there are ~ 6000 archive logs. Interestingly, they seem to get progressively smaller. At midnight the archive logs are over a 100M, by 7am they are down to 11M with occasional outliers.
This seems to be impacting my backups, which are taking 20 hours when I'd expect them to take less than 2.
Thanks in advance. Received on Wed Mar 18 2009 - 06:11:33 CDT
