Two special types of service execution process are required to run JCL jobs. These are:
Both types of SEP have a class property. The JOB CLASS of a JCL jobstream must match the class of a batch initiator SEP in order for the SEP to run the job. The MSGCLASS or SYSOUT class must match the class of a batch printer SEP in order for the SEP to print the output.
You can either define permanent batch initiator and printer SEPs or create SEPs during a session that exist only until the end of the session.
When you define a batch printer SEP, you can specify a printer exit module, which enables you to perform additional formatting of output data before it is printed. For more information see the section Printer Exit Modules in the chapter JCL Support in your MTO Developer's Guide, if you have the development documentation available.
If you want to create a batch printer SEP that uses a printer accessed across a network, you need to have started the enterprise server from the command line or from the IDE; if you start it from ES Admin, it runs as a system service and the network printers defined on your machine are not available.
