Finally received your reposne :) so using the JES CKPT dialog to move CKPT2 from the structure to DASD is a non issue? just wanted to be sure using $T CKPTDEF,RECONFIG=Y then using the option to reassign CKPT2 from STRNAME= to DATASETNAME= I've defined? thanks again

That way if either fails, you should be okay. Side Note: Moving the CKPT from CF to DASD or from DASD to another DASD is very easy. We have done ours during the day time. The process is very quick. There is a SHARE presentation from 2004: JES2 Checkpoint Reconfiguration >From the z/OS JES2 Initialization and Tuning Guide SA32-0991-00 In general, to prevent a total loss of the job queue, you should use 2 checkpoints, specify CKPT DUPLEX=ON on all members, and place CKPT2 on a DASD.
