Hi Ray,
There are two different fields in v$log
ARCHIVED - tells us if the log is archived or not
STATUS - tells us status of data in the log
- CURRENT - LGWR is currently writing this log
- ACTIVE - the transactions from this log aren't written to the
datafiles yet (checkpoint not complete), this log is required for instance
recovery
- INACTIVE - log could be reused
- and so on..
What'is important, you have the logs archived but not checkpointed.
this means, DBWR couldn't keep pace with your updates.
Do you have your datafiles on RAID-5? You have to distribute datafiles over
several disks (there are two main options - raid with striping, or manual
distribution) and may be consider partitioning for this table. Many
suggestions in this thread are also very reasonable. Just my $0.02

My system is in archive mode. What wonders me is that even after archive
files are created the status of the log file is in ACTIVE state.

Most of the times in an archivelog databases that happens because the arch
process is still working. If it was a noarchivelog database, it would be a
block recovering what is going on.
