PATHCOM

The Pathway transaction processing system enables you to create and manage

online transaction processing applications. In particular, Pathway controls the flow of

transactions between the input/output devices and the database used by an

application.

Pathway systems that use audited files must be configured to define how TMF works

with server classes and terminals, and how failures are treated. Use the Pathway

PATHCOM interactive command interpreter to configure and manage a Pathway

system. Table 1-2 lists the PATHCOM commands that have TMF-related options.

For further information about PATHCOM commands, see the Pathway PATHCOM

Reference Manual.
