Sample WLP Combined JCL

JCL was shown for each individual control statement in the previous examples, either WLP1 or WLP2. One job can be used to run both, but not at the same time. The following example shows the combined JCL. See also job N600 from the installation process.

The following is an explanation of the JCL statements required for executing a batch WLP run:

• EXEC Statement - Points to the WLP batch simulation program (PGM=SASSWP00) and optionally provides PARM information as control statement input.

  WLPCC DD Statement - Contains control statement information (WLP1 or WLP2). It is not required if PARM is specified on the EXEC statement.

  STEPLIB DD Statement - Points to the CA WA CA 7 Edition Load library. The Load library on which any WLB resource definitions (UCC7Rxxx indicated on RES statements) reside must be referenced by this ddname.

The following Projection report DD statements are referenced only for WLP1:

• UCC7WLP DD Statement - Points to the data set that is to contain JOB and RES statement data created by the FWLP command or produced manually. It is required for WLP1 reports and ignored for WLP2.

  INTRPT DD Statement - Hourly INIT Usage Projection Report

  TP1RPT DD Statement - Hourly TP1 Usage Projection Report

  TP2RPT DD Statement - Hourly TP2 Usage Projection Report

  CPURPT DD Statement - Hourly CPU Usage Projection Report

  RESRPT DD Statement - Resource Summary Report

The following DD statement is referenced only for WLP2:

• UCC7LOG DD Statement - Points to a standard CA WA CA 7 Edition log history/archive file. It is required for WLP2 commands, but ignored if WLP1 is specified in the control information.

The following DD statements are referenced for both WLP1 and WLP2:

• MSGRPT DD Statement - Produces error message reports reflecting control statement and data statement edit errors.

  DETRPT DD Statement - Produces the Detailed Resource Utilization and Job Summary reports.

The practice of saving the statement data sets generated by the FWLP command and concatenating pertinent ones for projection runs can enhance flexibility and increase usefulness of the WLP facility. For example, if a data file is created that contains the specifics for an existing application and it is known that a new job is to be added to this application, the effects of the new job can be tested if there is a separate data file with only that application. One way to do this would be to create a new data file with only the new job, and run it concatenated with the file that has the other jobs in the application.

This technique not only adds flexibility in usage but can also reduce runtime for projections by keeping the number of variables being exercised to a minimum.
