Consider carefully the methods of defining terminals for transaction routing,
and decide which is most suitable for your network before you start to use
RDO:
- Use the shipping method, unless you use terminals that are known
by different names in different systems. For ATI to work with the shipping
method in a transaction owning system, you may need to use the XALTENF and
XICTENF global exits. See the CICS® Customization
Guide for programming information on these exits.
- Use the sharing method for systems with a shared CSD file, if you
use the same names in different systems and you do not want to use global
exits to ensure that ATI works.
- Use the duplicating method if you use terminals that are known
by different names in different systems, or if you use ATI to acquire terminals
but do not have a shared CSD file, and you do not want to use the XALTENF
and XICTENF global user exits.
You could use a mixture of methods: perhaps shipping for display terminals,
and duplicating for printers that need ATI to acquire them but without the
use of the XALTENF and XICTENF global user exits.
Before you start creating definitions for intercommunication resources,
see the CICS Intercommunication
Guide for further information. There, you can find useful examples
of the attributes you must specify for different types of links and sessions.
