Does HostBridge execute in the CICS TOR or AOR?
In CICS TS 1.3, the architecture of the 3270 Bridge interface is such that HostBridge (which uses the interface) must run in the same region as the application which issues the SEND/RECEIVE command (the Application Owning Region, or AOR). Thus, HostBridge would need to be installed/available in each AOR. Given HostBridge’s minimal installation requirements, this should be a simple matter. Note that CICS TS 2.2 changes the rules a bit with the introduction of the “Linkable Bridge Interface”. This interface will allow a single copy of HostBridge to facility access to multiple AOR’s. There is still some code running in each AOR to facilitate this, but it’s provided with IBM as part of CICS TS 2.2. ^ Back to Top How does CICS user authentication work with HostBridge? How CICS user authentication works is determined by the transport mechanism used to exchange requests/responses with HostBridge. In all cases, however, user authentication is handled by CICS (not HostBridge). For example, the
