The XCF Server is available to process server requests. You use the IXCREQ macro to format a server request message that can then be sent to the XCF Server on one or more systems in the sysplex through the IXCSEND macro. To send a request to the XCF Server and receive a response to the request, the requestor must do the following:

• Use the IXCREQ macro to construct an XCF Server request message. See Using the IXCREQ macro.
• Use the IXCSEND macro to send the request message to the XCF Server. See Using the IXCSEND macro.
• Use the IXCRECV macro to receive the response data from the systems that provided responses. See Using the IXCRECV macro.
• Use the mapping macro IXCYSRVR to interpret the XCF Server response data.
