Processing control with checkpointing

To write a checkpoint while JES is processing a sysout data set, code one of the following:

   //name     OUTPUT CKPTLINE=number,CKPTPAGE=number
   //ddname   DD     SYSOUT=class
               .
               .
   //name     OUTPUT CKPTSEC=number
   //ddname   DD     SYSOUT=class

Example 1

//J2       JOB    ,MHB
//S1       EXEC   PGM=ABC
//OT2      OUTPUT CKPTLINE=60,CKPTPAGE=40
//DDB      DD     SYSOUT=C

JES writes a checkpoint every 40 logical pages. A logical page contains 60 lines.

Example 2

//J2       JOB    ,MHB
//S1       EXEC   PGM=DEF
//OT2      OUTPUT CKPTSEC=60
//DDB      DD     SYSOUT=D

JES writes a checkpoint every 60 seconds.
