RE: Database using 100% of CPU

Are you using the OEM that came with 8.1.6? I have a dim memory that the JAVA executable that powers that version of OEM had a flaw that could consume 100% of the CPU. Personally, I don't use OEM versions after 8.1.5.

It sounds like you may need more ram.

I've looked at the server. Total Commit Charge is 574968. Total Physical Memory is 523680. I can see that it's over, but what am I looking at? I understand physical memory, but the help on 'Commit Memory' in windows is less than helpful.

Do I need to reboot the box?

Thanx,
Mike

Check Task Manager | Performance tab, compare Commit Charge Total (LL corner) vs. Physical Memory Total (UR corner). You should stay below physical RAM as much as possible, because Oracle really does not like NT virtual memory.

I haven't found a cause yet either. Rebooting seems (so far) to be the only cure. If you get any replies would you please summarize to the list?

Vergara Oracle DBA Guidant Corporation (909) 914-2304 -----Original Message----- Sent: Friday, August 17, 2001 9:41 AM To: Multiple recipients of list ORACLE-L We are having a problem with our database - it is using 100% of the CPU. This has only started happening recently, and restarting the database temporarily stops it happening - it usually recurrs a few hours later. There are no jobs running, and at the moment there are no active connections. Obviously something has kicked this off, can anyone shed any light on this or suggest how to find out what is running on the db? Thanks in advance, Steven H.
