Look in the alert logs for things such as checkpoint not complete. To resolve these problems you may try to re-size
your current redo logs are add more redo log groups

Hi!

Thanks for your reply!

1.Would Shutdown Abort command be accepted when LGWR hangs!!!

Try always the shutdown immediate. Before you try the abort, since it requires recovery.
