If you suppress operator verification and you have predefined a replacement checkpoint data set, JES2 automatically forwards the checkpoint data set that experienced the I/O error. To suppress operator verification, specify OPVERIFY=NO on the CKPTDEF initialization statement or on a $T CKPTDEF command. Automatic forwarding allows you to minimize disruption to your production systems. JES2 follows your predefined instructions and forwards the checkpoint data set as specified on the CKPTDEF statement. You are not prompted to change those instructions at reconfiguration time, thereby reducing the time required to complete checkpoint reconfiguration. If you suppress operator verification (that is, if you specify
OPVERIFY=NO) and NEWCKPTn= has been specified, JES2 takes the following
default reconfiguration actions:
