Greetings.
I am in the process of upgrading a client's zOS 2.1 systems to zOS 2.3,
which means among the many other challenges, configuring a working
zOSMF. It was up for some time on the 2.1 test system, however not
until the 2.2 repackaging retro-fit was applied.
A sentence I encounter frequently is, "z/OSMF can run on a parallel
sysplex, monoplex, or XCF local mode environment." See for example,
page 4 of the IBM z/OS Management Facility Configuration Guide.
For the last two decades, most of my clients have relied on "basic
sysplex" for GRS signalling -- not being able or willing to afford a
parallel sysplex or carve out an LPAR emulating such; it has simply not
been a part of the strategic plans. What are the options, then, for
zOSMF moving forward? Can the LPARs remain a basic sysplex, with zOSMF,
say, operating in some sort of basic mode, e.g. on the test system only?
I should say, by the way, that the less fragile CA-CSM software manager
has worked very well for us since it was rolled out on the test system
at version 5. It is not used to deploy, only to upgrade and maintain CA
program products, which are then rolled to the other systems in the
basic sysplex through more familiar, traditional means.
Thanks in advance,
Tom Sims
