Generating batch-job skeletons

To ensure that all files are correctly allocated, you must generate the batch-job skeletons before creating the sample job JCL.

Several controller functions, such as daily planning, are performed by batch jobs that are submitted from the Tivoli Workload Scheduler for z/OS dialog. To generate the skeleton JCL for these jobs:

Select option 2 from the EQQJOBS main menu. This panel is displayed:

```
EQQJOBS1 ------------ GENERATE TWSz BATCH-JOB SKELETONS --------------------
 Command ===>

 Enter the name of the output library. This should be a fully qualified
 data set name without any enclosing apostrophes. This library should be
 allocated to ISPSLIB.

 Batch-job skeletons   ===> CCOPC.OPCA.JCLSKELS_____________________________ 

 The following data set names are used by one or more of the generated job
 You can specify an asterisk (*) to indicate the name of the subsystem.

 Message library name  ===> OPC.SEQQMSG0____________________________________ 
 Parameter library     ===> CCOPC.*.PARM____________________________________ 
 Member in parameter
  library              ===> BATCHOPT 
 Checkpoint data set    ===> CCOPC.*.CKPT____________________________________ 



 Press ENTER to continue
```
Batch-job skeletons

Required input. Enter the name of the library where the JCL skeletons are to be stored. Before you use the Tivoli Workload Scheduler for z/OS dialog to submit batch jobs, allocate this library to the ISPSLIB DD statement in the TSO session of dialog users.
Step 13. Setting up the ISPF environment explains how you set up the dialog. You can create a new library for the skeleton JCL members or put them in an existing skeleton-JCL library.

In the following fields, you can enter &XOPCNM. as one of the qualifiers for the data set names. This is an ISPF variable that is stored in the profile and is the same variable that you specify in option 0.1 (SUBSYSTEM NAME) in the Tivoli Workload Scheduler for z/OS dialogs. When a skeleton is then used by a dialog of the scheduler, &XOPCNM. is substituted with the name of the scheduler subsystem that is being used.

Ensure that &XOPCNM. ends with a period if it is not the low-level qualifier. For example, you could enter CCOPC.&XOPCNM..PARMLIB but CCOPC.&XOPCNM.PARMLIB results in a JCL error.

If you enter an asterisk (*) as a data set qualifier, the generated skeletons will contain &XOPCNM. in place of the asterisk.

Message library name

Required input. Enter the name of the library that contains the Tivoli Workload Scheduler for z/OS messages (SMP/E target DD name SEQQMSG0).

Parameter library

Required input. Enter the name of the library that will contain the initialization statements.

Member in parameter library

Required input. Enter the name of a member in the parameter library that will contain the BATCHOPT initialization statement. The Tivoli Workload Scheduler for z/OS batch jobs will use this member. If you have not already created the BATCHOPT statement, you can still generate the batch skeletons, but remember to create a member with the same name when you create the initialization statements.

Checkpoint data set

Required input. Enter the name of the checkpoint data set.
Press Enter, and this panel is displayed:

EQQJOBS2 ------------ GENERATE TWSz BATCH-JOB SKELETONS -------------------
 Command ===>

 Enter the following required job stream parameters:
 Non-VSAM dsn prefix ===> CCOPC.*___________________ 

 

 VSAM dsn prefix     ===> CCOPC.*V__________________                         

 Unit name           ===> 3390____      Default unit name                    

 Unit name (temp ds) ===> SYSDA___      Unit name for temporary data sets     

 Unit name (sort ds) ===> SYSDA___      Unit name for sort work data sets     

 SYSOUT class        ===> *             SYSOUT class for reports 

 The following information is optional:

 STEPLIB dsname        ===> OPC.SEQQLMD0____________________________________ 

 STEPCAT dsname        ===> ________________________________________________ 

 EQQMLOG dsname        ===> CCOPC.*.MLOGBAT_________________________________ 

 The following information is REQUIRED WITH DBCS support:

 KJSRTBL dsname        ===> ________________________________________________

 Press ENTER to generate OPC batch-job skeletons
```
Non-VSAM dsn prefix

Required input. Enter the qualifiers that prefix the non-VSAM data set names. Tivoli Workload Scheduler for z/OS adds a low-level qualifier to the prefix to uniquely identify the non-VSAM data sets. For example, it adds JTARC for the job-tracking archive data set. If the subsystem name is OPCA, the data set name will be CCOPC.OPCA.JTARC when the skeleton is used by the dialogs.

VSAM dsn prefix

Required input. Enter the qualifiers that prefix the VSAM data set names. Tivoli Workload Scheduler for z/OS adds a low-level qualifier to the prefix to uniquely identify each Tivoli Workload Scheduler for z/OS VSAM data set. For example, it adds WS for the workstation description data set. If the subsystem name is OPCA, the data set name will be CCOPC.OPCAV.WS when the skeleton is used by the dialogs.

Unit name

Required input. Enter a device name that is valid at your installation. This can be a device type, for example 3380, or a group name, for example PROD or TEST.

Unit name (temp ds)

Required input. Enter a device name that can be used for temporary data sets.

Unit name (sort ds)

Required input. Enter a device name that can be used for sort-work data sets.

SYSOUT class

Required input. Specify the SYSOUT class that you want to use for the reports that are generated by the batch jobs.

STEPLIB dsname

Optional. Enter the name of the Tivoli Workload Scheduler for z/OS load module library if the load modules are not in a data set included in an active LNKLST member.

STEPCAT dsname

Optional. Enter the name of a private catalog if one or more data sets cannot be reached via the master catalog. To customize the EQQAUDNS skeleton clist with the appropriate loadlib that should be referenced when audit/debug is invoked, you must specify the dsname.

EQQMLOG dsname

Optional. Enter the name of a message log data set if messages are not sent to SYSOUT. This must not be the same data set that is used by a tracker, controller, or standby controller.

KJSRTBL dsname

Required if you use the Japanese language feature. Enter the name of a data set that will be used when sorting fields containing DBCS data.

Press Enter. The following panel is displayed:

Note:

In controller MLOG dsn, EQQTROUT dsname, and EQQAUDIT output dsn you can use an asterisk (*) for the subsystem name. It will be replaced with the current subsystem name when the dialog is invoked.

Press Enter when you have entered the information on panel EQQJOBSA. The dialog now generates the batch-job skeleton members.
After completing this procedure, you can proceed with the creation of the sample job JCL as described in Creating the sample job JCL.

If you are not sure at this stage what some of the values will be, it does not matter. You can rerun the dialog as many times as you want to regenerate the skeletons. You can also edit the generated skeletons manually.

This table shows the JCL skeleton members that EQQJOBS generates:
