JES3 capabilities
z/OS 2.3 provided additional support for JES3 JECL statements. TM has provided support for these statements since 1995. The table below outlines the differences. For full details on TM JES3 Support reference the JES3 Compatibility Service Guide.
JES3 to JES2 support comparison - z/OS 2.3 vs ThruPut Manager
For JES3 environments needing to convert to JES2, the chart below addresses the differences between the support currently offered by IBM and ThruPut Manager support, which has been available since 1995.
If TM detects that the IBM JES3 processing is active (INPUTDEF JES3JECL=PROCESS) then TM ignores all JES3 statements and allows IBM to process them. Additionally a message is issued to the job to indicate this. DTM11118I JES3 JECL ignored due to 'INPUTDEF JES3JECL-PROCESS'
JES3 Control Statement | IBM Support | TM Support |
