Preset Environment Concept

A preset environment is a state of initialization necessary for the execution of certain DO KSL and DO TSO statements. A preset environment is managed entirely by the procedure specified in the INITPROC subparameter in the rule definition. The procedure is either a KOA script, or a TSO command, CLIST or REXX procedure. Procedures handling KOA or TSO environments must be defined to Control-O prior to activation of the rules that call the procedures. Depending on the type of call (INIT, RESET, TERM) to the procedure, the preset environment is initialized, reset, or terminated.

• An INIT call establishes the preset environment.
• A RESET call restores the preset environment to the state it was in after initialization.
• A TERM call terminates the preset environment.

For example, for a preset environment named CICSP, a KOA script called CICSP should be defined to perform the environment functions shown in Table 195, which are passed as a parameter.

The type of server determines the instances in which each of the calls is performed.
