Hello Experts,

i am getting new problem with one of the database running on 9.2.0.7 version. suddenly it is generating too many archive logs.
i have checked in the alert log , tablespace status, datafile status and checked for backup too. i could not able to get any useful hint from the database.

i have checked incoming transaction that is also looks normal.

i was not able to find problem. can any one help me to find the problem.

How ARCHIVE_LAG_TARGET will avoid redo generation?

One possible solution is to increase the size of redo logs.

Of course this will not reduce the size of redo logs generated just the number of archived logs.
And I think OP problem is the size not the number in itself.

If you run StatsPack / AWR then that will tell you what's running at the moment.

You could look in V$Session to see what sessions are currently active, and then look at v$sql to see what the SQL being run is.
