The IBM recommendation for dump space can be found in MVS: Setting Up a Sysplex. From z/OS R12: You can define only one dump space in each coupling facility; however, that dump space can contain several structure dump tables. IBM® recommends that you specify 5% of the available storage in a coupling facility for dump space. If you do not specify any coupling facility dump space, none will be allocated and no structures in the coupling facility can be dumped. >Not only that, while IBM tries to keep CFSIZER accurate, as >I'm sure some members of this list could attest to, it has not been the most >reliable tool over the years and is not an officially supported either. Reliable as in "not available all the time" or reliable as in "gives wrong answers"? If the latter, it would be odd, as last I knew, the application behind the webpage actually asked a current CF what the right size should be given the user's input.
