HP OSMS Blueprint: Database Server on HP Server Platforms with MySQL and RHEL5
Frequently Asked Questions
Q: What do I do if any of the following errors display in the OVOW console during the SPI or
instrumentation deployment phase?
• Error:Action could not be executed because the contacted managed
node is using an AgentId different to the AgentId the action server
expected
• Error:Node is already managed by another management server
A: If you are having issues with the nodeId, use the following procedure:
1. At the managed node, enter the following command:
# /opt/OV/bin/OpC/opcagt –kill
2. Delete the file /var/opt/OV/conf/OpC/agentid.
3. Open the file /var/opt/OV/conf/OpC/nodeinfo and remove the first line containing
OPC_AGENT_ID.
4. To remove the id from the server, select the node, right-click, and select
Properties→General→Advanced Configuration. You can now remove the id.
5. At the managed node, enter the following command:
# /opt/OV/bin/OpC/opcagt –start
6. Deploy the policies from the server.
This generates a new AgentId for the node.
Q: After installing the mysql5 RPM package, the following error displays:
Starting MySQLCouldn't find MySQL manager or server[FAILED].
What is the cause?
A: This error is caused by the my.cnf file that comes from mysql4 or an earlier version. To
correct the error, enter the following commands:
[root@bl30p-1 ~]# mv my.cnf my.cnf.old
[root@bl30p-1 ~]# /etc/init.d/mysql start
Q: After changing the MySQL data directory, the stop or start command was executed in
MySQL at the HP OVOW management console. The following error displayed:
MySQL manager or server PID file could not be found!..failed Starting
MySQL..done
What do I do?
A: This error is caused by an OVOW agent's config.file that has not been synchronized. To
correct this problem, perform the following procedure.
1. Enter the following commands:
# cd /var/opt/OV/bin/instrumentation/DBSPI/conf
# vi dbspi_mysql.cfg
2. In the dbspi_mysql.cfgfile, find mysql_datadir="/var/lib/mysql" and change
the directory to your MySQL data directory.
3. Save the file, exit, and restart using the following commands:
# /opt/OV/bin/OpC/opcagt -stop
# /opt/OV/bin/OpC/opcagt -start
