The Connection Screens

The three screens available for maintaining connection instances are labeled Update, Inquiry, and Browse. The respective screens allow you to make an inquiry concerning a specific connection, to browse a list of all connections, or to disable/enable a connection.

A connection instance is an established TCP/IP connection between a remote endpoint and a Requester or a Handler. For the purposes of TMA TCP for CICS, a remote endpoint is an TMA TCP gateway gateway executing within a remote Oracle Tuxedo domain.

PF Keys

The following function keys are available on various connection screens.

Table 4-4 Function Keys

Function Key	Definitions

ENTER	Process the selection code entered

PF3	Transfer to Main Menu

PF5	Transfer to Connections Browse screen

PF7	Display the previous page of records

PF8	Display the next page of records

Note: If you enter data and press PF3 or PF5 before pressing ENTER, the current operation process is aborted and the new screen is displayed.

Update Connection Screen (C2)

Use the UPDATE CONNECTION screen to update a record from the Connection file. When the screen initially displays, the LOGICAL MACHINE NAME and TYPE fields are unprotected. Enter a valid LOGICAL MACHINE NAME (gateway ID) and TYPE and press ENTER. The screen re-displays showing the data from the record you specified and the STATUS field is unprotected. The message RECORD READY FOR UPDATE displays. You can now make changes to the record.
