Application Research of IP Direct Connection to Access Mainframe Using CICS Web Support

Abstract

CICS Web Support provided some CICS services, so that users could directly invoke and access the application in CICS through web browser. Users could use web-aware program to process web request and response. The paper used a case of CICS Web Support to process non-http request, to do application research of CICS Web Support IP direct connection to access mainframe. By determining the length of received data through the global pointer in CICS Web Support, the sample program realized the two times' invocation of Analyzer. At the same time, we finished the conversion of code page, and in user program, we received the requested data transmitted from Analyzer by applying BLI interface. In CICS side we used TSQ to record the program invocation in the non-HTTP processing. The conclusion is that it is feasible for IP direct connection to access mainframe using CICS Web Support function.
