I want to compress all the load data sets on a volume. it includes system datasets and personal datasets. I will do this in a maintanance window such that no dataset got locked by any one/system.

| If you are "not sure" whether or not your load libraries are in the link list or used by CICS or other tasks, I would suggest finding that out before proceeding further. |
