NOTICE

IBM intends to sunset the CFSizer web application in 4Q26. Its function has been incorporated into the z/OSMF Sysplex Management service’s CFRM Policy Editor beginning at z/OS V2R5, and as part of that platform the sizing function is both formally supported and more robust. IBM recommends that all CFSizer users transition to using z/OSMF for workload-based structure sizing. A discussion of the z/OSMF structure sizing support as well as documentation can be found at the following links:

Note: The sunset of the CFSizer web application will not impact the availability of the SIZER utility.
