How to control JES2 initialization

This topic discusses initialization and configuration features of JES2. Specific considerations unique to NJE are discussed in Network job entry (NJE).

JES2 initialization is performed after JES2 is started and before JES2 begins to process jobs. To control JES2 initialization:
  1. Create a data set containing the initialization statements.
    For a description of the different methods for specifying an initialization data set, see:
  2. Select initialization statements to be entered at the console during JES2 initialization.

    For more information, see JES2 initialization control statements.

  3. Update the JES2 procedure to include definitions of the initialization data set(s). IBM® suggests using PROCLIB statements instead of JCL changes.

    For more information, see Creating the JES2 cataloged procedure.

  4. Select start options to be used during JES2 initialization.

    For more information, see Specifying the Start Options.

  5. Use the exit and scanning facilities to modify initialization processing and thus modifying or supplementing JES2 functions.

    For more information, see Controlling initialization using JES2 exits and the $SCAN facility.
