1.4.1 z/OS CICS Concepts in a CICS Runtime Environment

Developers and administrators used to working in a z/OS CICS environment naturally want to know how concepts familiar on the source platform are implemented on the target platform.

The following table gives an overview of how the source platform notions have an equivalent on the target platform.

Table 1-1 Source Platform Notions

CICS Session	TUXEDO Session
Transaction First Program	Tuxedo Service Program associated with service
L.U.W.SYNCPOINT [ROLLBACK]	Transaction tpcommit()/ tpabort()
