Status: Closed |
DUMPSHM OPTION FOR DB2FODC MAY MISS MUCH OF SHARED MEMORY FOR CONFIGURATIONS LARGER THAN 4GB |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
When the new compact shared memory dump option is set
(DB2FODC="DUMPSHM=ON") and DB2 abends, DB2 dumps significant
areas of shared memory to a a binary dump file in the FODC
folder. When the configuration of a memory set is larger than
4GB (the most common case being database memory), important
portions of shared memory may be missed. This may result in
support being unable to determine the root cause for the abend. |
| Problem Summary: |
****************************************************************
* USERS AFFECTED: *
* DB2 Servers using the compact shared memory dump feature *
* (DUMPSHM=ON) are affected *
****************************************************************
* PROBLEM DESCRIPTION: *
* See Error Description *
****************************************************************
* RECOMMENDATION: *
* Diagnostic fix only - Upgrade to DB2 Version 9.7 Fix Pack 11 *
* if the compact shared memory dump feature is required. *
**************************************************************** |
| Local Fix: |
avoid using the DUMPSHM option - used in conjunction with
CORESHM=NO. Rely on the default full coredump behaviour (do not
set CORESHM=NO). |
