I need help with jcl issue..so a step is amending with sb37 space abend. Data class is specified jumbo 2 for the op file. And no space parameter specified. They are asking what should they give should they give cylinders or what data class

Hello.

DFSMS data classes are installation specific and, as far as I am aware, there are no standard definitions shipped with z/OS. It might be that your system has been set up be very restrictive in what you can do with storage allocation, or it might be quite lax. Either way, there's not much I can say without actually being logged on to it to see how your system is configured. You can try setting a specific space allocation and see what happens, but if you are still having problems then the best course of action would be to talk to your sysprogs/storage administrators about the most appropriate class to use for your space requirements.

Yes, I am following up with storage team but not much yet told.
