If an application program coded with checkpoint/restart is writing to an output GSAM database defined as an MVS GDG, and the program abends and needs to be restarted, what needs to be changed in the JCL to run the restart?
On the initial run doing the checkpoint the GSAM GDG would look like this:
//GNFIXAOT DD DSN=TEST.GSAM.GDG.FILE.D00005(+1),
// DISP=(NEW,CATLG,CATLG),
// DCB=(DSORG=PS,RECFM=FB,BLKSIZE=0,LRECL=133),
// AVGREC=U,
// SPACE=(133,(500,100),RLSE)
If the restart will read the GSAM file to reposition the dataset, then it begins to write to the dataset, how does the DD need to look for the restart? |
