Adding a NODE Object

After you have set all the attributes for a NODE object, you add the NODE object with

an ADD statement. For example, the following PXMCFG statements define a client and

a server NODE object:

SET NODE ROLE CLIENT

SET NODE SYSTEM \UK2

SET NODE CPUS (1:22, 3:31, 5:31, 6:8, 9:8)

SET NODE HOMETERM $OSP

SET NODE PRI 122

ADD NODE CLIENT1

SET NODE ROLE SERVER

SET NODE SYSTEM \UK3

SET NODE CPUS (1:13, 2:30, 3:9, 4:18, 5:30)

SET NODE HOMETERM $OSP

SET NODE PRI 166

ADD NODE SERVER1

Configuring the PATHMON Processes

Use the SET PATHMON statement to configure your PATHMON processes. For

example, you might need to specify a name for the well-known named PATHMON

process to be used by Pathsend requester programs, or you might want to request error

dumping.

Although there can be multiple PATHMON processes in a Pathway/XM environment,

all of them must have the same configuration. Therefore, there is no need for an ADD

statement for PATHMON processes. As with the PATHWAY object, the configuration

used is the working set of attributes effective at the end of the PXMCFG source file.

For the complete syntax of the SET PATHMON statement, including descriptions of all

the attributes you can set for the PATHMON object, refer to SET PATHMON

page 10-30.

Identifying System and CPU Resources for PATHMON Processes

In the Pathway/XM environment, the PXMCOM process starts the PATHMON

processes, creating additional PATHMON processes as needed to manage the TCPs and

server processes it creates. You use client NODE objects to define the systems and

CPUs where PXMCOM can start PATHMON processes.

You use the NODES attribute of the SET PATHMON statement to define which client

NODE objects in your configuration will be used to define the CPU resources for

running PATHMON processes. In this attribute, you provide a list of NODE object

names. For example, the following statement defines three NODE objects that specify

resources for PATHMON processes:

SET PATHMON NODES CLIENT1, CLIENT3, CLIENT4

All the NODE objects names must match NODE objects defined in your PXMCFG

sourcestatement file with ROLE set to CLIENT. In addition, in the SET PATHMON

NODES attribute you must specify one and only one NODE object for each unique
