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 :-)
The log files that may contain important system operation and error messages are described here for reference purposes.
On Unix location is /var/opt/OV/log. Among log files:
There are also several installation logs
If an HPOM error message has been produced, check the meaning and possible resolutions using the opcerr command. The message will start with the string OpC” and contain a body and tail as shown in the following example.

Some Oracle database error messages have two parts ORA-xxxx. When you need to gather more information about the error, use the utility program $ORACLE_HOME/bin/oerr. This program will produce useful information about the error and troubleshooting tips.

If there is a message in the message browser from the Oracle database, the message text will include the error message number. With this information, you can check the message with the oerr command as shown in the next example. Sometimes the error messages are very complex and could signal major trouble. If you are not sure what corrective action is required, report the error to your Database Administrator or support vendor.
# $ORACLE_HOME/bin/oerr ORA 01547 01547, 00000, "warning: RECOVER succeeded but OPEN RESETLOGS would get error below" // *Cause: Media recovery with one of the incomplete re//covery options ended without error. However, if the //ALTER DATABASE OPEN RESETLOGS command were attempted now, //it would fail with the specified error. The most likely //cause of this error is forgetting to restore one or more //datafiles from a sufficiently old backup before executing //the incomplete recovery. // *Action: Rerun the incomplete media recovery using dif//ferent datafile backups
