Configuring TN Server
If you choose a different port number that is not in use on the TN server, you also need to con
figure that
port number on the TN3270 clients (or start the TN3270 clients using an option to specify the port number).
Port numbers above
2000 are likely to be available. Port numbers in the range 256–1023 may give slightly
better security, but are more likely to be in use.
If you want a TN3270 client to be able to use more than one LU or LU pool, de
fine multiple access records,
each with a different TCP/IP port number, so that you can identify the different LUs or LU pools by specifying
different port numbers.
Display LU assigned
The name of the LU that the TN3270 client accesses when it is active. The LU must be a dependent LU on
the local node. You can specify the name of an LU pool rather than the name of a particular LU.
Printer LU assigned
The name of the default printer LU or LU pool for clients that use this access record. This LU must be
defined as a dependent LU on the local node.
Allow access to specificLU
Specify this option to enable TN3270E and TN3287 clients to request a specific LU for a session. (This
option is not available to TN3270 clients.)
Additional Configuration
After performing the TN server access configuration, continue with the following configuration tasks:
• Configure TN server association records as described in Section 9.1.2, Configuring TN Server Association
Records.
9.1.2 Configuring TN Server Association Records
A TN server association record defines an association between a printer LU and display LU, so that the TN3270E
or TN3287 protocol can connect the two. If the access record for the client permits selection of a specific LU, this
record enables a client to select a specific printer by specifying the associated display LU.
To configure a TN server association record, use one of the following methods:
Motif administration program
Select
TN Server
from the Services menu on the Node window, then select the Association Records pane on
the TN Server window and choose
New.
Command-line administration program
Issue the following command:
define_tn3270_association
TN Server Association Record Configuration Parameters
The following parameters are required for TN server association record configuration:
Display LU
The name of the display LU (which must be defined on the local node).
Printer LU
The name of the printer LU (which must be defined on the local node). Do not specify a printer LU that has
been entered on another TN server association record.
