Conﬁguring Dependent LUs

Deﬁning LU Types 0–3

6 Conﬁguring Dependent LUs

This chapter provides instructions for conﬁguring LUs and LU pools to support user applications that use 3270,

TN3270, RJEand LUA communications. To use these, you must conﬁgure dependent LUs.

Before you can conﬁgure the resources described in this chapter, you must perform the following conﬁguration:

• Conﬁgure the node as described in Section 4.2,

Conﬁguring the Node.

• Conﬁgure connectivity as described in Chapter 5, Deﬁning Connectivity Components. For 3270, TN3270,

RJEand LUA, you must conﬁgure the link to support dependent LU trafﬁc.

You do not need to conﬁgure a direct link to the host if you are using upstream PU concentration or DLUR.

For more information, see Section 9.2, Conﬁguring PU Concentration and Section 5.3, Deﬁning DLUR PUs.

6.1 Deﬁning LU Types 0–3

You must conﬁgure dependent LUs of types 0–3 to support communication with a host system. You can use the

information in this section to deﬁne an LU to support 3270, RJE or LUA. You can also deﬁne a range of LUs, to

conﬁgure multiple LUs of the same type in a single operation.

To conﬁgure an LU of types 0–3, use one of the following methods:

Motif administration program

Select one of the following from the

Services menu on the Node window.

•

3270 and either

New 3270 display LU

New 3270 printer LU

• RJE and New RJE LU

•

LUA and New LUA LU

• TN server

and New host LU

Command-line administration program

Issue one of the following commands:

define_lu_0_to_3

define_lu_0_to_3_range

You can use the advanced dialog to restrict access to a speciﬁc SSCP, or to specify an inactivity timeout.

Note

If you are conﬁguring a 3270 display LU for use with the SNAplus2 3270 emulation

program, and users may use this LU for ﬁle transfer, the host conﬁguration for this LU

must specify DFT mode (3279 conﬁguration), and not CUT mode (screen mode). Although

there will be no difference when using the LU for 3270 emulation, SNAplus2 does not

support CUT mode ﬁle transfer. If an LU is conﬁgured at the host as CUT mode, any

attempts to transfer ﬁles on a session using this LU will fail.

Check the host logmode table entry for the LU with your host administrator. The query bit

in the PSERVIC operand of the MODEENT macro must be set to indicate a DFT mode

LU; this means that the third hexadecimal digit (upper digit of the second byte) of the

PSERVIC operand must be
