Note: HP renamed the product called now HP operations manager way too many times. Also it is very inconsistent with using abbreviations. Here we will assume that the term "HP Operations manager" and abbreviations HPOM, OMU, and OVO mean the same thing :-)
In HPOM opcmsgm is message manager which receives messages from the managed nodes through the message receiver (opcmsgr). The messages can be correlated, regrouped and logged by the message manager running on the management server. The message manager is also responsible for adding annotations, triggering notifications, and forwarding the message to the trouble ticket and notification service manager for external notification and trouble ticket generation.
This problem demonstrates itself when the process opcmsgm aborts frequently with OpC40-687, OpC20-87 and OpC40-679 errors. No messages are delivered to operator GUI.
This problems is connected with the fact that There is at least one duplicated agent_id in the opc_nodes table in the Oracle database. The agent_id column holds coreIDs which must be unique. This column is updated after a certificate grant but it can be altered also manually (with the opcnode tool).
It can be caused by several different reasons:
There is HP document KM831198 ( HPOM 9: opcmsgm aborts frequently: Problem within HPOM message correlation module detected. (OpC40-679) ) from Aug-30. 2010
It provides a good method to diagnose the problem while incorrectly stating that it was resolved in patch OML_00006 (Linux) or PHSS_41175 (HP-UX):
This problem is registered as QCCR1A101191 and now solved on :
Linux by OML_00006 : Server patch 09.01.300
HP-UX by PHSS_41175 : IA-64 cons. server 09.00.250
Here are some key quotes:
Operations Manager for UNIX ( HPOM ) 9.0. The process opcmsgm aborts frequently after logging the following messages to the /var/opt/OV/log/System.txt file:
0: ERR: Wed Jan 20 10:54:13 2010: opcmsgm (23750/1): [opcmsgm.c:16121]: A severe error caused the main controller loop to abort. (OpC40-687)
0: ERR: Wed Jan 20 10:54:33 2010: opcmsgm (23750/4): [opcmsgm.c:5203]: Select failed: errno=Bad file number. (OpC20-87)
Problem within HPOM message correlation module detected. (OpC40-679)
The problem happens during a license check where opcmsgm expects a single row to be returned from an SQL (Structured Query Language) query.
They provided workaround:
The following SQL query can be used to identify nodes with duplicate coreID:
select label,node_id,agent_id from opc_nodes where agent_id in (select agent_id from opc_nodes group by agent_id having count(*)>1 and agent_id<>'000000000000000000000000000000000000');
as in the following example:
$ sqlplus opc_op@ov_net
SQL*Plus: Release 220.127.116.11.0 - Production on Mon Jan 25 18:13:58 2010
Copyright (c) 1982, 2008, Oracle. All rights reserved.
Oracle Database 11g Enterprise Edition Release 18.104.22.168.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> select label,node_id,agent_id from opc_nodes where agent_id in
(select agent_id from opc_nodes group by agent_id
having count(*)>1 and agent_id<>'000000000000000000000000000000000000');
In the example above, both nodes (node1 and node2) are cloned systems and the HPOM administrator has set the coreID of both of them using opcnode on the server.
The problem disappears after changing the coreID of one of the nodes by running this command on the node:
ovcoreid -create -force
removing the old certificates on the node (ovcert -list / ovcert -remove), requesting new certificates (ovcert -certreq) and granting them on the server.
