This section describes how to link edit the Model 204 utilities. This step must be performed whenever installing a new version of Model 204.

Many of the utility load modules are compatible across versions of Model 204; therefore, your z/OS jobs which use older versions of those load modules will continue to perform correctly when used in conjunction with the new version of Model 204, and you do not need to change the JOBLIB nor STEPLIB JCL — for example, you do not need to change any of your batch jobs which have PGM=BATCH204.

However, for some utility load modules, you must use the new version. These modules are:

  1. A few utilities are sensitive to the Model 204 journal and checkpoint format. Therefore, when you are using the following utilities, you must use the version of the utility which is the same as the version of the checkpoint or journal dataset it processes:
    AUDIT204Extract from journal, and report stats and analysis
    MERGEJMerge concurrent journal streams
    UTILCInformation from checkpoint stream
    UTILJInformation from journal stream; add EOF markers

and

  1. In addition to the above utility load modules, be sure to read the sub-section titled "Important instructions for version m.n", for the version of Model 204 you are installing; it may contain instructions for other utility load modules for which you must use a new version.
