Function
This command releases free area (free page area) in the IM Configuration Management database.
If you delete a large number of hosts in the IM Configuration Management database, part of the area that was used to store that data might become used free area. This command changes used free area into unused free area so that it can be reused.
You can execute this command during operations without having to stop JP1/IM - Manager Service.
