Alert log and trace file monitoring
When a new error message appears in the alert_imsdb1.log file, an event is displayed on the OEM Console, as explained in “Monitoring events” on page 24.
Operators can also observe details in alert logs and trace files as explained in the following procedure. See “Fault management” on page 8.
Alert logs and trace files are located in the bdump directory as follows:
•$ORACLE_BASE/admin/imsdb1/bdump
ATTENTION
Nortel Networks recommends that you monitor database alert logs and trace files periodically to ensure there are no errors occurring in the Database Module.
Monitoring alert logs and trace files
In a telnet window
1Login as oracle to the primary or secondary database where the error message has been reported.
2Navigate to the directory containing the database as follows: cd $ORACLE_BASE/admin/imsdb1
If there are errors, the trace files corresponding to these errors are stored in the bdump or udump directories. Alert logs are stored in the bdump directory.
3Open the file in the appropriate directory (for example,
alert_imsdb1.log) and look for any errors at the end of the file.
