Defining a specific bridge facility name
If the name or netname of the 3270 terminal is important to the logic of the 3270 application, you can supply a specific name in the BRIH-TERMINAL or BRIH-NETNAME parameter on the Link3270 call and also optionally request that the autoinstall user replaceable module (URM) is called when the bridge facility is allocated.
The autoinstall URM is called if you specify the system initialization parameter AIBRIDGE=YES at CICS® startup, or use SET AUTOINSTALL to activate this option at a later time.
The AUTOINSTALL URM can accept, reject, or modify the supplied or generated terminal name and netname. See How bridge facility virtual terminals are autoinstalled for information about the autoinstall URM.
