Tuning and Troubleshooting OVO Solving OVO Server Problems 416 Solving OVO Server Problems This section explains how to solve specific OVO server problems. If the OVO Management Server Status is Corrupted The OVO management server status is completely corrupted, even after the ovstop opc and ovstart opc sequence. Problem There are many corrupted messages in the message browser. Many critical OVO error messages and OVO agents on managed nodes cannot be stopped or started. Configuration distribution does not work. Despite these symptoms, opcsv -status may report that not all OVO manager processes are operating correctly. Solution Erase all temporary files: 1. Stop all OVO GUIs that are running by exiting the OVO user interface: [File: Exit] 2. Stop the OVO management server processes: /opt/OV/bin/ovstop opc ovoacomm ovctrl 3. Erase all OVO temporary files: rm -f /var/opt/OV/share/tmp/OpC/mgmt_sv/* All pending messages (that is, messages not yet saved in the database) and all pending actions (that is, automatic actions, operator-initiated actions, scheduled actions, and command broadcast) will be lost. 4. Restart the OVO management server process: /opt/OV/bin/OpC/opcsv -start 5. Restart the OVO GUIs: opc Chapter 11
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 Chapter 11 417
