Tuning and Troubleshooting OVO
Solving OVO Server Problems
If Old Messages are Sent to the External Trouble
Ticket System
After a long downtime, old (no longer interesting or valid) messages are
sent to the external trouble ticket system or external notification service
when restarting the OVO management server.
Problem
Under a heavy system load, or if one instance of the trouble ticket
interface or notification service interface is already running, the
messages to be forwarded are queued in the following queue file:
/var/opt/OV/share/tmp/OpC/mgmt_sv/ttnsq
Solution
Erase ttnsq before starting the OVO management services again.
If the OVO management processes are stopped for a long time, the
pending requests are sent to the external interface after the OVO
management server is restarted, even if they are no longer of interest.
If HP OpenView Cannot Resolve a Hostname
When starting the OVO administrator GUI, the HP OpenView Windows
(ovw) Root window is created, but the following error message is
immediately displayed:
ovw: Could not resolve hostname (mgmt_server_host_name) for
licensing
Problem
HP OpenView Windows (ovw) does not have permission to look up the
name of the management server in the following file:
/etc/hosts
Hostname lookup is necessary for license checking.
Solution
Make sure that /etc/hosts is readable for user opc_op:
chmod 444 /etc/hosts
