Overview of APPC and LU 6.2

APPC allows application programs using APPC protocols to enter IMS transactions from LU 6.2 devices. The LU 6.2 application program runs on an LU 6.2 device supporting APPC.

APPC creates an environment that allows:

• Remote LU 6.2 devices to enter IMS local and remote transactions
• IMS application programs to insert transaction output to LU 6.2 devices with no coding changes to existing application programs
• New application programs to make full use of LU 6.2 device facilities
• Data integrity provided by IMS and in LU 6.2 environments that do not have a distributed sync-point function
