We upgraded Panvalet to 14.5 SP01 and relinked PAM. Do we need to relink PAM again when we upgrade to z/OS 1.11?
No, it should not need to be relinked for a z/OS upgrade. It only needs to be relinked when doing a Panvalet Release or SP upgrade and/or when any apply of maintenance hits PAM. The best way is to not statically link PAM in user programs and do the proper dynamic calls to PAM instead in the user program.
