Early this week I had asked about using the CHGPGM command to remove observability and compress program sizes that all responders said to forget about. One mentioned using the Compress Object CPROBJ command to save on space usage and speed up backups. Is anyone using this command on a regular basis to reduce the size of objects that can be compressed that only get used infrequently like year-end processes? If you do run it do you only compress your own objects or do you do a system wide compress? I am considering running this CPROBJ OBJ(*ALLUSR/*ALL) OBJTYPE(*ALL) DAYS(90) every week end when system use is low. Or would CPROBJ OBJ(*ALL/*ALL) OBJTYPE(*ALL) DAYS(90) be a better choice. I did a test on our development library which has 2,915 objects. 2,901 were scanned by CPROBJ, 464 were able to be compressed and space usage for the library went from 3,924,838,912 down to 3,833,350,656. Not a big change. But, of the 464 objects that were compressed space usage went from 150,269,952 down to 58,781,696. Not bad.
