This topic outlines the procedures necessary for configuring BARR/NJE to use 802.2, HPR/IP, and SDLC connections. These procedures are required. Your host programmer can help configure the link settings.
You must be a member of the local Administrators
group to operate the NJE Configuration Utility. If you are assigned the
Configure - NJE user
access right on the computer to which you are trying to connect, but
are not a member of the Administrators
group, the NJE Configuration Utility will operate in read-only mode.
You can also define
routing tables to route jobs from BARR/SPOOL and messages from NJE
Console to host nodes on the NJE network.
Configure the connection
Use the NJE Configuration Utility to define and configure 802.2 LLC2 connections for communicating with the host. The procedures outlined in this topic are required. Your host programmer can help configure the link settings. Complete the following steps to configure the connection.
The BARR/NJE software
with the 802.2 communications link emulates an IBM 3777 PU type 2 device
and strictly follows the IBM SNA protocol using IEEE 802.2 DLC. You must
provide a network connection that appears to the BARR/NJE device as if
it is connected by the mainframe communications device to a local or adjacent
token ring (FEP, 3172/3174, OSA, SNA gateway, or host-attached router).
You must install the DLC
protocol before you can use an 802.2 communication link.

Dedicated lines are private or leased lines, rather than public ones. or switched A standard dial-up telephone connection; the type of line established when a call is routed through a switching station.. Use a leased line for data communications. A switched link is a standard telephone line. Choose one of the following types: Leased, Switched: manual, Switched: modem-stored number, or Switched: application-stored number. The default link type is Leased.
Specify the Data rate for communications if necessary. This value can be changed only when the Leased link type is selected. All other link types will use the default setting, 9600, to issue modem commands.

AT – Select this option if you have an external AT modem that supports the standard AT command set (Hayes compatible) and can automatically dial a phone number entered in the software. You can only have one modem configuration.
If you select AT, enter the Phone number for the autodial connection. The default phone number is DT9,12345551234. You can also specify the Initialization string. The default initialization string value is AT&F&M1.
Click OK. You are now ready to configure the Barr SNA node.
You must configure the Barr SNA node using the parameters provided to you by your host programmer. Complete the following steps to configure the Barr SNA node.
From the Barr
SNA Configuration dialog box, under NJE
logical unit, in the Name
box, type the SNA LU name. This must match the luname
parameter specified during VTAM
configuration.
In the Number box, type the LU number as a decimal. This must match the LOCADDR parameter specified during VTAM configuration.
Click OK.
After you have configured your 802.2 LLC2, HPR/IP, or SDLC connection, you must configure the NJE node. You must use parameters provided to you by your host programmer. Complete the following steps to configure the NJE node.
For JES2, you can save time and configure
the NJE node to start automatically using NetView.
From the Connection
Configuration dialog box, next to NJE
Configuration, click Modify.
The NJE Configuration dialog
box displays.
Under BARR node, enter the Barr node Name. This must match the BARR/NJE node name specified during JES2, JES3, or POWER configuration. The Location box is currently unavailable.
Under Host node, enter the host node Name. This must match the host node name specified during JES2, JES3, or POWER configuration.
Select the host node Type. If you are using JES2 or JES3, select MVS/JES2. If you are using POWER, select VSE/POWER.
Click Advanced.
The Advanced Node Settings
dialog box displays.
Under Passwords, specify a Send password and a Receive password, if desired. The send password is the password sent to the host to authenticate the BARR node. The receive password is the password the BARR node expects to receive from the host to authenticate the host node. By default, the passwords are blank.
The Features
fields are set for optimal performance and are compatible with host systems.
Under Streams, configure the number of streams. This must match the number of streams specified during JES2 or POWER configuration. If you are using JES3, skip this step.
The host's receivers correspond to BARR's transmitters,
and the host's transmitters correspond to BARR's receivers. For example,
if the host is configured for 5 SYSIN transmitters, the SYSIN receivers
field must be 5.
Click OK twice, and then click Close.
When you click OK to close the NJE Configuration Utility, a message displays asking if you want to restart the BARR NJE service. Click Yes.
After you have completed configuring BARR/NJE, you must start the Barr SNA node. You will then be ready to use BARR/NJE for printing management.
Complete the following steps after the BARR NJE service has restarted.
Verify that the NJE LU is activated.
Issue the start networking command at the host console. This command differs for JES2, JES3, and POWER.
For JES2:
$SN,A=applid
where applid is the NJE LU name set in VTAM and JES2 configuration.
For JES3:
+S SNA,NODE=nodename
where nodename is the BARR/NJE node name set in JES3 configuration.
For POWER:
pstart pnet,nodename
where nodename is the BARR/NJE node name set in POWER configuration.
A message will display on the host console indicating that the node is active. If this message does not appear, use the Operator Console to diagnose the problem.
No additional configuration is needed for receiving print jobs. Once the NJE connection is operational and the node has been started at the host, jobs will automatically be received into the spool. From BARR/SPOOL, you can reroute jobs to various destinations using a header field.
To send a test print job, request that the job be submitted from the host to BARR/NJE and use the Barr node name as the destination. Anyone on the host can route their job to an NJE node using the DEST= parameter in their JCL. For example, you could specify DEST=barrnode in your JCL where barrnode is the BARR/NJE node name specified during JES2, JES3, or POWER configuration.
//SYSOUT DD SYSOUT=A,DEST=barrnode
You can also route the job to a specific printer in the Barr spooler by adding the printer name to your destination parameter. Enter the Barr node name, followed by a comma, and then the printer name. Because the DEST= parameter contains two parameters, you must use parenthesis as shown in the following example.
//SYSOUT DD SYSOUT=A,DEST=(barrnode,HPLASER)
