Step 10: Configuring a 3270 LU for the 3270 Applet

In order to use the SNA Server 3270 Applet for 3270 terminal access to the host system a 3270 LU must be configured for use by each terminal session.

  1. In the Connections folder select the connection over which the 3270 session will be used.
  2. In the Insert menu select 3270 and then Display LU at which point the 3270 LU Properties dialog box should appear.
  3. Set the LU Number for this dependent LU. This must match the LOCADDR number as specified on the Dependent LU definition configured for use as a 3270 terminal. This is found under the PU definition for the SNA Server machine in VTAM.
  4. Enter the LU Name for the 3270 LU. This should match the name of the Dependent LU definition configured for use as a 3270 terminal. This is found under the PU definition for the SNA Server machine in VTAM.
  5. Now select the Display Model tab in the 3270 LU Properties dialog box.
  6. Set the Display Model attributes. These can usually be left to default to 2 (24x80) and Model can be overridden
  7. Click the OK button to complete the 3270 LU configuration
