NJE - Configuring JES3

Configure MVS/JES3 to add an NJE node for Barr. You must also define lines and streams for the node. Later we will test to make sure the NJE node has been configured correctly.

JES3 does not support sending data to the host.

  1. Add a NJE node

  2. Review JES3 configuration example

Adding a NJE node

Define the BARR/NJE node to JES3 by adding another NJERMT in SYS1.PARMLIB(JES3IN00)and a BDT macro An instruction in a source language that points to a sequence of instructions in the same language to replace it. in SYS1.PARMLIB(BDTIN00). The following JES3 NJE definition contains statements your host programmer must enter for each Barr node. More advanced macros and parameters are documented in IBM's OS/390: JES3 Initialization and Tuning Reference.

Initial BDT installation

If this is an initial installation of BDT, you must define your host's NJE node to BDT. This is completed by defining the JES3 host node. See the following example.

SYSID,NJENAME=hostnodename,NJEAPPL=hostnodename
BDTNODE,N=hostnodename,TYPE=NJE

For SNA connectivity, add the following line.

NJERMT,NAME=hostnodename,HOME=YES

For a Barr SNA or SNA connection

NJERMT,NAME=nodename,HOME=NO,TYPE=SNA
BDTNODE,N=nodename,CS=NJEDUP,L=BARRMOD,APPL=luname,A=YES,ASR=20,TYPE=NJE

Parameter

Description

NAME=nodename

Replace nodename with the NJE node name. This is the value the BARR node will be identified as on your NJE network. It is used for routing, messages, and JCL. This value is also the Barr node name specified when configuring NJE for Barr SNA or SNA.

APPL=luname

Replace luname with the NJE LU name specified during VTAM configuration. This must also match the NJE LU name specified when configuring NJE for Barr SNA or SNA and the SNA gateway.

L=BARRMOD

Replace BARRMOD with the VTAM logmode table entry specified during VTAM configuration.

To improve efficiency, you can set other parameters such as LU, BUFSIZE, and BUFNO. See IBM's OS/390: V2R6.0 BDT Installation manual for more information.

Review JES3 configuration example

The following is a sample SYS1.PARMLIB(JES3IN00) configuration for a single host node connected to NJE.

NJERMT,NAME=JESA1,HOME=YES

 

NJERMT,NAME=BAR1NJE,HOME=NO,TYPE=SNA,STREAM=2

 

BDTNODE,N=BAR1NJE,APPL=TB201NO1,A=YES,ASR=50,TYPE=NJE,BFSIZ=4096,BUFNO=8,CS=NJEDUP,

L=BARRMOD,LU=17

Parameter

Description

JESA1

The host's NJE node.

BAR1NJE

The NJE node definition for BARR's node. It has 2 transmitters. It is an SNA connection with 17 virtual LUs and the maximum RU size.
