  8. Troubleshooting Process • Note the precise details of the problem • Check the Error Message Reference Manual or run opcerr • Check the VPO Administrators Reference Manual • Run itochecker • Check through the rest of this module • Use the VPO tracing option • Check the HP Web site for support information • Call the HP Response Center VPO Troubleshooting

  9. Agent/Server Installation & Runtime • Examples of problems • “The Management Server will not start” • “The Managed Node processes will not start” • “The VPO Oracle database returns errors” • “My VPO backups aren’t working” • “I keep getting communication errors to the nodes” VPO Troubleshooting

  10. Windows and Messages • Examples of problems • “My operators can’t login to Java/Motif GUI” • “A message was supposed to arrive in my browser….it didn’t!!” • “I get duplicate messages in my browser” • “Batches of old messages keep arriving in my browser” VPO Troubleshooting

  11. Distribution • Examples of problems • “A distribution error message keeps appearing in my browser” • “I distributed new config, but the messages are in the old format” • “I created a new template, did a distribution and…...nothing!!” VPO Troubleshooting

  12. Actions, Commands and Monitors • Examples of problems • “Automatic Actions keep failing” • “Some Actions will not stop running” • “Some of the operators can’t run their applications” • “My new monitor is giving me weird errors” • “One of my monitors can’t start because the previous one is still running” VPO Troubleshooting

  13. /var/opt/OV/share/tmp/OpC/mgmt_sv/trace /opt/OV/bin/OpC/install/opcinfo /opt/OV/bin/OpC/install/opcsvinfo When all else fails…..trace! Managed node Management server OPC_TRACE TRUE OPC_TRACE_AREA MSG, ACTN OPC_TRACE_TRUNC FALSE OPC_TRACE TRUE OPC_TRACE_AREA MSG, ACTN OPC_TRACE_TRUNC FALSE VPO agent processes VPO manager processes opcagt -trace or opcagt -start opcsv -trace or opcsv -start /var/opt/OV/tmp/OpC/trace VPO Troubleshooting
