Defining the CONFIG Parameter
You can define the CONFIG parameter in the PARM field in a JCL statement to allow platform servers to submit requests to a platform server for z/OS. This is an usage of the PARM override facility.
Required Parameter
CONFIG: defines the name of the CONFIG entry within the FUSCFG configuration entry. It can contain up to 24 characters, and must match the CONFIG parameter within the FUSCFG member of the FUSCFG DD statement.
The FUSCFG CONFIG entry can be defined to communicate through TCP, SNA, or Cross Memory Services. The advantage of using these methods of communication is that all configuration data for communicating to the platform server started task is controlled within a single file. If the connectivity information for a started task changes, the FUSCFG entry can be changed so that individual batch jobs do not have to be changed.
