Initialization statements and parameters

This topic explains how to specify the JES2 initialization statements and parameters and how JES2 performs initialization under different conditions.

Throughout this information, an initialization statement refers to a JES2 specification that can contain further parameter specifications. For example, PRINTDEF is a statement; LINECT, DBLBUFR, and UCS are parameters on that statement. Most initialization statements contain a set of parameters that relate to a single JES2 function. For example, the SPOOLDEF statement contains several parameters used to define the JES2 spool volume environment. Some statements, however, contain no parameters (for example, DEBUG: this statement is either specified as DEBUG=YES or DEBUG=NO).

Table 1 provides an alphabetic list of the JES2 initialization statements and briefly describes the function of each. It is intended as a reference to help you decide which statements and parameters to use to initialize your JES2 member. z/OS JES2 Initialization and Tuning Reference describes each of these statements in detail and specifies their functions, formats, and default values.
