7.2 APPC/IMS Programming
The Oracle Tuxedo Mainframe Adapter for SNA system supports non-transactional and transactional IMS servers using either the implicit APPC support for IMS or the explicit APPC interface using APPC/MVS calls from a user application. Any IMS program that gets messages from, and puts messages into, the IMS message queue can be used without change as either a client or server.
To use the implicit APPC capabilities of IMS, you must modify
the APPCMxx
file in the SYS1.PARMLIB
library provided with your Oracle Tuxedo Mainframe Adapter for SNA
software. The configuration parameters in this file associate the
LU with the IMS scheduler. You must identify the LU representing
the application name used by Oracle Tuxedo Mainframe Adapter for
SNA to access the IMS region and the IMS system ID which provides
scheduling for inbound requests. Be sure to discuss with mainframe
support personnel the changes you make to the APPCMxx file.
