DB2 - Problembeschreibung

Problem IC79197 Status: Geschlossen

DB2 INSTANCE COULD HANG WHEN MESSAGE QUEUE RESOURCES ARE SCARCE

Produkt:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problembeschreibung:
In certain rare scenarios it is possible for a DB2 instance on 
UNIX/Linux to hang when the system runs out of message queue 
resources.  This type of hang is mostly commonly encountered 
while executing parallel loads.

* PROBLEM DESCRIPTION:                                         * 
* Sending messages on system message queues may block forever  * 
* when resources are scarce.  Stack traces will show threads   * 
* blocked in msgsnd.                                           * 
**************************************************************** 
* RECOMMENDATION:                                              * 
* Retry the operation.  Increase system message queue          * 
* resources in the kernel if possible.  Upgrade to DB2 v9.5    * 
* fixpack 9.                                                   * 
****************************************************************
Local-Fix:
Retry the operation with less parallelism.  If possible, 
increase the message queue resources configured in the kernel.
