Jim, It sounds like you want to reorganize this catalog. What you have will work, but keep in mind that a LOCK will simply not allow access to the catalog. That is, the requester receives a non-zero return code and the request fails. If the catalog has entries for any online datasets, and online needs an extent of a file, you are going to have some serious issues to deal with as the request will not 'wait' for you to release the LOCK, but will fail.
