This Knowledge Document explains how to detect loops within a schedule issuing 'Loop Detected' or 'Limit Reached. Loop?'.
CA Jobtrac JM currently offers two methods to detect successor loops:
The 'L' line command and the (sample REXX) Imod LOOPDET as explained below.
//jobname JOB . . . your accounting data . . .
//STEP1 EXEC PGM=SRVBATCH,PARM='LOOPDET'
//STEPLIB DD DISP=SHR,DSN=your.Jobtrac.CAILIB
// DD DISP=SHR,DSN=your.GSS.CAILIB
// DD DISP=SHR,DSN=your.DATACOM.CUSLIB
// DD DISP=SHR,DSN=your.DATACOM.CAILIB
//IMOD DD DISP=SHR,DSN=your.sample.REXX.ISET.file
//JOBTRACx DD DUMMY with 'x' as your Jobtrac Token
//PARMLIB DD * ADDRESS JOBTRAC GJTRGCUU 15 MAXTASK 5 TYPE 3
//ISRVLOG DD SYSOUT=*
//OUTPUT DD SYSOUT=*
