Two Approaches to Configuring Objects
Two Approaches to Configuring Objects
You can configure your Pathway/XM environment in either of two ways:
•
Create a configuration source file by manually keying in all the statements. Then use
the PXMCFG utility to create a SuperCTL file. This is a batch-type approach.
•
Use the Pathway/XM Analyst tool, which provides an interactive approach. Based
on the information you enter on a series of interactive screens, the tool builds a
relational database on your terminal containing all the appropriate configuration
parameter values, and displays the workload and resource distributions provided by
the configuration. You can modify these values, as needed.
When you are ready, Pathway/XM Analyst generates a configuration source file
ready for you to transfer to the system in which Pathway/XM is to run. You can use
a text editor to open that file and add any other configuration statements needed.
Configured Objects
The types of objects you configure are the following:
PATHWAY object TERM objects
NODE objects PROGRAM objects
PATHMON object ROUTER objects
PLAN objects SERVER objects
TCP templates SERVICE objects
PATHWAY Object
The PATHWAY object represents the entire set of management objects in the
Pathway/XM environment. You configure it to set global parameters affecting the entire
environment.
NODE Objects
A logical node, or NODE object, defines a set of processor (CPU) resources on a
particular Compaq system and, optionally, default object attributes used for either
requesters (clients) or servers in the Pathway/XM environment. The ROLE attribute
identifies whether a NODE object is used for requesters (a client NODE object) or
servers (a server NODE object). Client NODE objects also define the systems and
CPUs used for PATHMON processes. A Pathway/XM environment includes one or
more client NODE objects and one or more server NODE objects.
One process broker (PB) process is created for each NODE object in the Pathway/XM
environment. The PB processes use the NODE specifications for automatic balancing of
the transaction workload.
A NODE object represents a logical, rather than a physical (Expand), node. However, it
is associated with a particular physical node.
