Configuring and Administering Oracle TMA TCP for CICS

It is the responsibility of the Oracle Tuxedo administrator to set up the configuration file, but close coordination with the Oracle Tuxedo application developer and the CICS programmer is necessary.

The following subsections describe the Oracle Tuxedo Mainframe Adapter for TCP (CICS) (hereafter referenced as TMA TCP for CICS) Maintenance System. The Oracle TMA TCP for CICS Maintenance System is an online CICS application for use in configuring, maintaining, and administering the TMA TCP for CICS gateway. The following topics explain the Maintenance System:

zMenu Navigation

zThe Main Menu

zThe Connection Screens

zThe Requester Screens

zThe Outbound Service Information Screens

zThe User Connection ACCOUNT Screens

zThe Inbound Service Information Screens

zThe Handler Configuration Screens

zDynamically Configuring TMA TCP for CICS

zAdministering the Gateways
