Writing the resource checker

Stabilized feature: CICS® support for Open Network Computing Remote Procedure Call (ONC RPC) is stabilized. Consider exposing and orchestrating applications as API services by using z/OS Connect Enterprise Edition or CICS web services, or by writing web applications in Java or Node.js. See also Stabilization notices and discontinued functions.

Your resource checker program must be called DFHRPRSC. There can be only one resource checker in a CICS region. The resource checker allows you to check the credentials of inbound client requests.

The resource checker can check the client address, passed as an input parameter, against a list of known clients for the host on which the request has been received. The password passed to the resource checker is blank.
