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

Monitoring alert logs and trace files

In a telnet window

1 Login as oracle to the primary or secondary database where the

error message has been reported.

2 Navigate 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.

3 Open the file in the appropriate directory (for example,

alert_imsdb1.log) and look for any errors at the end of the file.

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.
