This appendix describes non-IBM software products than can assist you in the conversion of your JES3 JCL and JECL to the JES2 equivalent. These products provide functions that might allow you to run JES3 JECL and JCL unchanged on a JES2 system.

This appendix includes the following topics:

Trident Services’ z/Operating System Environment Manager (z/OSEM) offers a methodology and ISPF interface that provides dynamic controls. In addition to the dynamic controls that are offered, it facilitates JES3-to-JES2 migrations by providing a migration path from JES3 to JES2 by including most of the workload routing functionality of JES3.

It also can reinterpret JOB JCL if z/OSEM Job Classing is used to change a JOB’s CLASS to obtain JES2 default values, such as TIME.

z/OSEM also provides support for the JES2 parameter in the initialization deck JOBDEF INTERPRET=JES|INIT, JES2 Exit 59, and JES2 Exit 60.

Compuware’s ThruPut Manager Automation Edition does not run with JES3. However, it can be of invaluable assistance to an installation that is converting from JES3 to JES2 by providing equivalent functions to some of the JES3 capabilities that are otherwise lost or pose a significant challenge to such a conversion.

The support that is offered by IBM as of this writing and ThruPut Manager Automation Edition is compared in Figure F-1 on page 265.
