Classification: Confidential You can create a separate JESPLEX within your sysplex. As long as you do not share CKPT/SPOOL you should be ok.

Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] I am installing z/OS 2.4 on my sandbox system and discovered I have inadvertently missed some PTFs on both 2.4 and 2.3 to resolve a JES2 downlevel condition. JES2 (in a MAS) produced errors and will not start until this issue is resolved. I've applied the fixes for both z/OS environments but need to migrate those fixes to development and production lpars that are still under z/OS 2.3 and all in the same MAS configuration. My question is this: Temporary condition: Is it okay to fire up a different JES2 spool and checkpoints on the sandbox system, removing the MAS definitions,etc. while still being part of the sysplex *and* those systems still believing that the sandbox JES2 is still part of their MAS? That will allow me to continue to work on the z/OS 2.4 implementation without waiting for our change management process to propagate the fixes across the other environments. Or do I need to IPL as a monoplex? Or do I need to wait until the fixes have been installed across the board?
