How about CFSIZER and translate the storage requirements into space requirements?
-----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Lizette Koehler Sent: Tuesday, January 17, 2017 10:03 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: How to calculate the JES2 Checkpoint and Spool Space Cross posting to TSO REXX and IBMMAIN Long ago IBM Created an APAR OY44087 which provided some guidance and formula on how to calculate space for the JES2 Ckpt and Spool space. I am looking to create a REXX/ISPF function or Excel to mimic this process. However it is lacking on how some of the newer control blocks, like BERTS, would affect this calculation. Does anyone have any idea how to create a process for generating the sizing for JES2 based on the newer resources that have been added since OY44087? I know if I try to increase a resource and there is insufficient space, JES2 will prevent the change from occurring and then tell me what it needs. I think issuing the command to "see if it works" is not a really practical method. Particularly if you really did not want to change it at that time. I looking to build a "what-if" tool that could help one validate the JES2 environment will be able to handle any resource changes. And if it cannot, then what should it be raised to.
