Pinned topic RDz UT 8.0.1 Config: Which PARMLIB to customize BPXPRMDB?

‏2011-12-20T00:35:33Z |
(Another) z/OS noob question...

After creating the HFS files for /tmp and /u, the RDz UT Config Guide says, "...change PARMLIB member BPXPRMDB as follows...."

Which PARMLIB is the right one to use for this? Should I edit ADCD.Z111S.PARMLIB(BPXPRMDB)? Or copy ADCD.Z111S.PARMLIB(BPXPRMDB) to USER.PARMLIB(BPXPRMDB) and edit that one?

I guessed: edit ADCD.Z111S.PARMLIB(BPXPRMDB). Will there be dire consequences?

Thanks in advance,
Larry.

    Shouldn't have any dire consequences, but I think the correct answer is to copy ADCD.Z111S.PARMLIB(BPXPRMDB) to USER.PARMLIB(BPXPRMDB) and edit that one. The idea is that you don't want to edit the system defaults, just in case you get into a situation where you have to roll back. Also, it will make it a lot easier to upgrade down the road if everything you've changed (parmlibs, proclibs, etc.) are in one spot (USER.*). In the future you can simply replace the z/OS volumes with the latest versions and with very minimal effort have your system back up again with the same configuration.

    Thanks, Scott!

    That makes sense, and I appreciate the explanation. Undoing my "guess" is no big deal - I can copy the modified one over to USER.PARMLIB and undo the edits in ADCD.Z111S.PARMLIB(BPXPRMDB).

    Thanks again,
    Larry.
