Re: Deadlocks

Hi,

One way to find out locks is to run the script catblock.sql (rdbms/admin) which creates two views dba_blockers & dba_waiters. They should provide you with enough info to find out who is blocking who.

Subject: Deadlocks

A monitoring tool that we use here is reporting that our database has a deadlock. We have not noticed it and there are no complaints.

I challenged the company to tell me how they determine this. They are checking the v$sysstat for the value of "enqueue deadlocks" which in this case is 1.

Is this correct? Is there a change from V7.x to 8.1.5 in how you would determine a deadlock condition?

thanks,

..tom
