Chung Sent: Thursday, January 28, 2010 8:38 PM To: [email protected] Subject: Re: VM DB2 7.3 question Hi Bill, This means the agent wants to read a directory block from disk, but there are no available directory buffers, so the agent waits for another agent to free up a buffer. When a buffer is freed, this agent will be "un-waited" so it can try to get the buffer again. This indicates an increase in the number of Directory buffers is needed. There is also an "out of page" wait state for when page buffers are all in use. I hope this helps. ...Roland --- On Thu, 1/28/10, Bill Pettit <[email protected]> wrote: --- snipped --- -----Original Message----- From: The IBM z/VM Operating System [mailto:[email protected]<http://ca.mc881.mail.yahoo.com/mc/[email protected]>] On Behalf Of Bill Pettit Sent: Wednesday, January 27, 2010 5:20 PM To: [email protected]<http://ca..mc881.mail.yahoo.com/mc/[email protected]> Subject: VM DB2 7.3 question We encountered several slow running batch jobs last night and the only thing that stood out was the following entry when the operator command SHOW ACTIVE was entered: User Agent: 4 User ID: ONLINE is R/O APPL 2431F6FE Agent is processing and is in out of block wait. I have been searching off and on through the manuals today and I still cannot find any reference to the "Agent is processing and is in out of block wait" condition, and what it is attributed to. I suspect it has something to do with a shortage of the lock request blocks allowed and available for an active user, but I cannot find anything that actually tells me that.. Anyone have any knowledge about what this message means? Thank you Bill Pettit
