Configuring the NJE auto-start feature (optional)

BARR/NJE

This can only be used with SNA connections to a JES2 host.

The NJE auto-start feature is an optional feature for SNA connections only. At this point, your SNA administrator should have already configured the SNA gateway for the PU and you should have already configured the SNA gateway for an NJE LU. Use the following steps to configure VTAM and the SNA gateway for a local APPC Acronym for Advanced Program-to-Program Communication. A specification developed as part of IBM's SNA model and designed to enable applications programs running on different computers to communicate and exchange data directly. auto-start LU.

Complete the following steps to configure the NJE auto-start feature.

Use BARR job for the NJE auto-start configuration

Configuring VTAM for an auto-start LU

You must create an LU name in VTAM for the local APPC auto-start LU. The following line must be added to the existing PU definitions located on your host in SYS1.VTAMLST. See the Configuring VTAM topic for more information.

luname0

LOCADDR=0,USSTAB=,DLOGMOD=#INTER

Parameter	Description
luname0	Enter the LU name for the local APPC auto-start LU. This value must match the local APPC auto-start LU when you configure BARR/NJE for SNA. You will also use this value when you configure the SNA gateway (Microsoft SNA Server) in the next step.
DLOGMOD=#INTER	Names the logon mode table entry used by the auto-start LU.

To activate the VTAM PU, enter the following commands at your MVS Console:

v net,inact,id=VTAMMEMBER
v net,act,id=VTAMMEMBER

where VTAMMEMBER is the library member that contains the PU definition.

Configuring Microsoft SNA Server

Your SNA administrator has configured a Microsoft SNA Server connection for the BARR/NJE PU defined to VTAM and you have activated the PU and configured Microsoft SNA Server for an NJE LU. Complete the following steps to configure a local and remote APPC LU.

Configuring a local APPC LU

Open Microsoft SNA Manager.
Select the connection you want to configure from the list on the left side of the window.
On the menu bar, select Insert | APPC | Local LU. The Local APPC LU Properties dialog box displays.
Select the General tab and enter these values:

LU Alias – the LU name used for the APPC auto-start LU in VTAM configuration.
Network Name – the network identifier.
LU Name – the LU alias.

From the Local APPC LU Properties dialog box, select the Advanced tab.

Select Independent.
Make sure Member of Default Outgoing Local APPC LU Pool is not selected.

Configuring a remote APPC LU

Again, select the connection you want to configure. On the menu bar, select Insert | APPC | Remote LU. The Remote APPC LU Properties dialog box displays.
Select the General tab and enter these values:

LU Alias – Enter the LU name for the BARRSN Server found in Step 1 of the BARR$SN1 job instructions.
Network Name – Enter the network identifier.
LU Name – Enter the LU Alias.
Uninterpreted Name – Enter the LU Alias.

From the Options tab, select these settings:

Select Supports Parallel Sessions.
Select No Session-Level Security.
