In order to describe the environment and resources used in an OCF network, two sets of definitions must be made tailored to your installation requirements. Additional steps must be performed to secure online access to remote Beta product subsystems.
VTAM resource definitions define the VTAM resources that will be used by the OCF network nodes.
These describe to the OCF functions the names and types of Beta product subsystems residing on the local z/OS system which are addressable via the OCF network. The OCF network definitions also describe the names of the partner OCF nodes with which the local OCF node can converse.
Finally, you must perform the same initialization steps on the local z/OS system, with the same subsystem ID, security exits, and security profiles as on the remote CPU. This is done to provide the same level of security checking on the local z/OS system as would be required on the remote z/OS system to access the resources in the Beta product started task.
Once in place, these definitions need not be reconsidered unless changes are made to the VTAM environment, or Beta product subsystems are added to the OCF network.
