ONPARAMS - Change logical and physical log configuration
This utility allows you to add logical logs, drop logical logs, and change the location of the physical log. This utility is handy because you can do some things with it that cannot be done with ONMONITOR. It allows you to add logical logs of different sizes and locations. One common use of this is after you have set up your server, you will often want to move your logs out of the rootdbs into their own dbspaces.
onparams { -a -d DBspace [-s size] | -d -l logid [-y] |-p -s size [-d DBspace] [-y] }
-p Change physical log size and location
-y Answer YES to all questions
In order to drop a logical log, the log must be backed up and cannot contain the current checkpoint or current logical log.
