Parameter manager domain’s generic gate

Table 78 summarizes the parameter manager domain’s generic gate. It shows the level-1 trace point IDs of the modules providing the functions for the gate, the functions provided by the gate, and the generic format for calls to the gate.

You can find descriptions of these functions and their input and output parameters, in the topic dealing with the corresponding generic format, in Domain manager domain’s generic formats.

In preinitialization processing, the parameter manager domain reads system initialization (override) parameters from the startup job stream and, if requested, from the SYSIN data set and the console.

If a system initialization table (SIT) has been specified, that is loaded into storage. Otherwise, the default SIT is loaded. The override parameters are applied to the SIT, and related parameters are checked for consistency. Errors are reported, but no action is taken.

The parameter manager domain also provides services to other domains as they preinitialize. It informs them of the type of start (cold or auto), and supplies information as required from the SIT.

In initialization processing, the parameter manager domain waits for all the other domains to complete their initialization, and then writes a warm start record to the catalog.

The parameter manager domain does no quiesce processing or termination processing.
