Out of private memory heap

8 New Member
Hi guys,

For last few days we are getting out of private memory error. We have a
development environment. We tried to figure out the problem but we
believe that it might be related to the OS (I am new to Windows so not
sure). We are currently bouncing the instance to overcome this error. This
generally happen at the end of business day only (So maybe memory
might be getting used up?). We have already increased the statement heap &
Application heap size. The task manager shows that only 1.8 gig out of
4 gig is being used by the entire system. So there is enough memory on
the system. Strangely db2syscs is only using 800 MB of RAM even when
memory is available & it is facing shortage of it. We first tried STMM
but later started giving fixed value to many of the parameters.

We are running DB2 9 Fix Pak 3 Express Edition on Windows Server 2003
SP2 32-bit 4 Gig RAM. The server has 1 instance which holds 2 database
and both of them get this error when the users try to log through the
application. Here is the db2diag entry:

kumarmdb2,

I added the code tags for you. Also, because of the amount of text you provided I broke it up to two different segments. This helps preserve the whitespace and make it more readable. When posting here please use the [code] [/code] tags.

Thank You,

Hi kumarmdb2,

the latter error messages seem to be caused by exhaustion of the application heap. Look for the db parameter APPLHEAPSZ, double it, restart the db and see if your sql is then working fine.

The error messages in the top just look like something is exhausting the virtual address space which is quiet restricted on 32bit systems. Perhaps the article "The DB2 UDB memory model" at http://www.ibm.com/developerworks/db...cle/dm-0406qi/ may give you a hint what's going wrong.

Hi Bernd,

Thanks for reply. I tried that but it did not helped much (it just delayed the occurence of error) but I would like to thank you from bottom of my heart for helping.

It is actually a DB2 bug which causes fragmentation of appl heap. As soon as we migrated to fix pack 4 the error stopped coming.


Cheers!

A bug? Huh, if doubling APPHEAPSZ doesn't help for long it must be. Thank you for posting this information. Btw., did you get to know which APAR fixes this bug?

Bernd
