Controlling the Execution of Transaction Programs

Two types of administrative data, a TP profile and side information, help control the flow of conversations in an APPC/MVS network. A TP profile contains the scheduling and security information that might be necessary to run a TP in MVS. Side information contains the translation of a symbolic destination name used by an MVS local TP when issuing an outbound allocate request. (APPC/MVS servers can also specify symbolic destination names when registering to receive inbound conversations.)

Both types of administrative data are stored in VSAM key sequenced data sets (KSDS), with at least one VSAM file for TP profiles and only one for side information. The APPC administration utility (ATBSDFMU) maintains the TP profile and side information files; you submit batch jobs that can add, modify, retrieve, and delete entries. An interactive panel dialog version of the APPC/MVS administration utility is available.

For information about the utility, see Using the APPC/MVS Administration Utility, and for information about the dialog, see Using the APPC/MVS Administration Dialog.

This chapter discusses the following aspects of controlling the execution of TPs:
