ick an INITSIZE value for which the default 75% value of MINSIZE could be
expressed in 1M (like 152M), you would see all the sizes displayed in 1M.

Mark,
If you can supply an example of the input (CFRM policy) and output (IXCMIAPU
report) for one of the structures that provides output in units of K instead of
M, I'll take a look.

helpful during migration, you must run it when both old and new CFs are
installed in the sysplex.

The CLUSTER support was part of what was supposed to be an over-arching
automation infrastructure that would provide a sysplex-level view of properties
and events for improved business resiliency. I don't think it ever came
together.

CFSizer will tell you what you need to know for sizing the CF structure, but
provides no information about other considerations for sizing the Logger
environment, like staging and log data sets. For that, refer to z/OS Setting
Up a Sysplex (SA23-1399)

As Peter points out, the Sizer utility, rather than CFSizer, is the tool of
choice for resizing structures in anticipation of a CFLEVEL change. CFSizer
(https://www-01.ibm.com/support/docview.wss?uid=isg3T1027062) is appropriate
when you're introducing a new workload or changing a workload for

glitches in the implementation at the new site, but we hope to get those ironed
out over the next few days.

The sample JCL in SYS1.SAMPLIB(IXCDELUT) should do what you want.

All couple data sets contain the sysplex name and can only be used in a sysplex
of that name, so they all have to be reformatted to define them with the new

can cause serious problems while it's practically impossible to go wrong by
moderately over-sizing a structure (assuming you don't exceed the CF's
