Use this command to manage the activity log
records by
date or size. The activity log contains normal activity messages generated
by the server. These messages include information about server and
client operations, such as the start time of sessions or device I/O
errors.
Activity log information
includes messages,
such as the following:
- Client session starts and ends
- Migration
starts and ends
- Diagnostic error messages
- Scheduled
administrative command output
At server installation, activity
log management is retention-based,
and the retention period is set to 30 days.
You can choose
to adjust the length of time that the activity log retains messages
to avoid insufficient or outdated data. The server automatically removes
the messages from the activity log after the retention period passes.
Alternatively,
you can choose to limit the total size of the activity log to control
the amount of space occupied by the activity log. The server will
periodically remove the oldest activity log records until the activity
log size no longer exceeds the configured maximum size allowed.
You
can issue the QUERY STATUS command to display the
current number of records in the activity log and the size (in megabytes)
that the activity log currently occupies.
Privilege
class
To issue this command, you
must have system privilege.

- Specifies
the number of days to retain messages in the activity
log when the log is managed by date, or specifies the maximum size
of the activity log when it is managed by size. With retention-based
management, a value of 1 specifies to retain the activity log records
only for the current day. With size-based management, a value of 1
specifies a maximum size of 1 MB for the activity log. You can specify
a number from 0 to 9999. A value of 0 disables activity log retention.

whether activity log management is retention-based or
size-based. This parameter is optional. The default is DATE. Possible

the server to retain activity log records for 60 days. Issue the command:
