RE: Log Switch hangup?

Why not set the log_checkpoint_timeout to zero? If you set it to 1200 you're forcing a checkpoint every 2 minutes.

Jared :

   Thanks for the reply. I know the log switch stops because 1) it doesn't advance in v$log_history for 2 hours 2)the pplication will commit after inserting every 3000 records. When I query the table, it still has only 3000 records even after 2 hours.

   I am able to login the database and do all the queries. Since it's just a test database, it's not in archivelog mode.

   I will set log_checkpoint_timeout to 1200, how about the log_checkpoint_interval (I use 10000), do I also have to increase? The redo log file is 20m each (4 redo logs).

   The application basically has one user with one big table of 1.1m records and some other small tables. In the java application, it has 15 connections with 12 threads, has some data contension when the 12 threads insert into another table at the same time(also 1.1m records).

   Glad to have the list and learn from you about the database tuning and application tuning stuff. Thanks.
