If you have a log that is getting very large, you can manually rotate the log at any time. Rotation backs up the existing log file and creates a fresh log file.
You can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help.
Rotate the log file.
$ dsconf rotate-log-now -h host -p port log-type |
For example, to rotate the access log:
$ dsconf rotate-log-now -h host1 -p 1389 access |
