z/OS JES2 Commands
SA32-0990-00

This describes how to:
  • Start, stop, and restart JES2
  • Control the JES2 processing environment independent of devices, jobs, and networks. Devices, jobs, and networks are discussed respectively later.

The following tables list the tasks discussed in this and provide a cross reference to the detailed descriptions of the corresponding commands.
