JES2 initialization is unsure of the checkpoint data set definitions because it was either unable to validate that the cold start times of CKPT1 and CKPT2 match or because it was unable to read either CKPT1 or CKPT2. JES2 wants the operator to confirm that it should use the data sets listed as checkpoints. If this message follows message $HASP457, JES2 has encountered an error on the forwarded data set. JES2 wants to confirm that it should use the new (forwarded) checkpoint data set(s).
