Issue/Introduction

We are in the process of migrating the JES2 checkpoint file CKPT1 from DASD to a coupling facility structure on our large parallel sysplex. CKPT2 will remain on DASD, as it is currently. We will run with DUPLEX mode on.   

Are there any MIM considerations for doing this?  This change was made on the small  test sysplex and everything worked fine with no MIM changes, but we are checking to be sure.

Environment

Release : 12.5

Component : MIM

Resolution

This change has nothing to do with the MIM product. No MIM changes or actions are required.
