Where is the TSIDCDK utility?
This Utility can be found in the Epic install Library. If it is not found when you run the following job
CREATE CA EPIC for z/VSE DSN CATALOG ON CKD
// ASSGN SYS240,151
// DLBL IJSYSDS,'EPIC.VSE.CATALOG',99/366
// EXTENT SYS240,TSI151,1,0,3750,63
// EXEC TSIDCDK CAT=IJSYSDS
Make sure that there is a LIBDEF for the Epic Lib in the partition you are running the job.
