Across the Boards - APPX Peer-to-Peer Communications
Cooperative Processing with APPXCooperative or client-server processing between applications on both mainframe and PC platforms is a necessity, as PC users require direct access to corporate information. An example might be a sales manager who needs to call up and/or alter customer information stored in a mainframe database. Across the Boards offers a method of intertwining applications on both platforms into a system where they co-process, enabling users to call up and manipulate database information at their convenience. This Across the Boards solution is called APPX.
Features and functions
At the request of the application programs on both the PC and mainframe ends, APPX establishes a session. In most cases, the first APPX (most often on the PC) will cause the second application to start running on the mainframe (for example, by starting a transaction in CICS). APPX then checks to see that the conversation is orderly, that is, it makes sure one peer is listening (receiving) while the other is talking (sending). The information is passed by way of logical records (any string of data with data type and length specified by the application program). The records may be up to 32K long. The transfer may include any type of information the two applications care to share; for example, the applications may take turns sending information back and forth, or one application may send a batch of records to the other.
