Location of stored configuration parameters

Most configuration parameters are stored in KN3ENV or KN3SYSIN members, which contain environment and startup values, though some parameters are stored in other locations.

Most configuration parameters and their configured values are stored in the KN3ENV or KN3SYSIN members of the &rhilev.&midlev.&rtename.RKANPARU data set for each runtime environment, where &rhilev is the runtime high-level qualifier, &midlev is the mid-level qualifier, and &rtename is the name of the runtime environment.

The parameters that are stored in the KN3ENV member are environment variables, which determine the operating characteristics of the runtime environment in which products and components are configured. The parameters stored in the KN3SYSIN member are startup parameters, which determine the default startup values for each product or component. Some environment variables and startup parameters are stored in members other than KN3ENV and KN3SYSIN, or in data sets other than RKANPARU.

There are additional parameters that are neither environment variables not startup parameters, but must be included in the runtime libraries for the products and components to operate correctly.
