Configuring POWER for NJE

To configure VSE/POWER, you must add an NJE node for Barr and define streams for the node. Later we will test to make sure the NJE node has been configured correctly.

Adding a BARR/NJE node for Barr SNA or SNA

Define the BARR/NJE SNA node to POWER by adding another PNODE in your pnet settings. The following POWER NJE definition contains statements your host programmer must enter for each Barr node.

More advanced macros Instructions in a source language that point to sequences of instructions in the same language to replace them. and parameters are documented in the IBM manual, VSE/Power Administration and Operation.

Parameter	Description
NODE=nodename	Replace nodename with the BARR/NJE node name. This is the value the BARR/NJE 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 BARR/NJE for Barr SNA or SNA.
BUFSIZE=32000	Use 32000 for maximum performance. You can conserve host resources by using a lower setting. Make sure your networking equipment can handle this frame size. Older equipment, such as 3174 cluster controllers, cannot handle this large frame size; therefore, you might need to set this parameter to a smaller value, such as 1024.
applid=luname	Replace luname with the NJE LU name specified during VTAM configuration. This must also match the NJE LU name specified when configuring BARR/NJE for Barr SNA or SNA and the SNA gateway.

A POWER configuration example has been provided to show the configuration for a single host node connected to BARR/NJE.

Adding a BARR/NJE node for CTC

Define the BARR/NJE CTC node to POWER by adding another PNODE in your pnet settings. The following POWER NJE definition contains statements your host programmer must enter for each Barr node.

Parameter	Description
NODE=nodename	Replace nodename with the BARR/NJE node name. This is the value the BARR/NJE node will be identified as on your NJE network. It is used for routing, messages, and JCL Acronym for Job Control Language. A command language used in IBM OS/360 mainframe systems. JCL is used to launch applications and specifies information on running time, program size, and the program files used for each application.. This value is also the Barr node name specified when configuring BARR/NJE for CTC.
BUFSIZE=1800	Use 1800 for maximum performance. You can conserve host resources by using a lower setting.

Starting the CTC connection

The CTC device is associated with the BARR/NJE node when the networking session is started. See the IBM manual, VSE/Power Networking, for more information.

Defining streams for the node

When you define streams for the node, you can use POWER's predefined number of streams or manually activate a node's stream. These stream values will also be entered later as BARR/NJE stream numbers when you configure BARR/NJE for Barr SNA, SNA, or CTC. You can view the streams for an active node by issuing the pinquire node=nodename command once the node is active.

Specify streams using default settings

If you choose not to define the number of streams, POWER uses the following default settings.

Specify streams using the PACT command

After the command to start the node has been issued, the number of streams can be set by activating or draining streams.

Parameter	Description
nodename	Replace with the BARR/NJE node name. This is the Barr node name specified when configuring BARR/NJE for Barr SNA, SNA, or CTC.
sttype	Replace with either tri or rvi, where i is the stream number. Use tri for a transmitter and rvi for a receiver.
jobtype	Replace with either job or out. Use job for SYSIN and out for SYSOUT.
