Pathway/XM Analyst Configuration Tool
When a processor is reloaded, the LCS rebalances the server processes in the system to
take advantage of the additional processor. This is done gradually over time, in parallel
with the servicing of the queue by existing server processes. The LCS deletes links to
server processes in loaded processors as their reservation expires; this action causes the
server class’s queue length to increase, triggering the creation of new processes in the
reloaded processor.
Pathway/XM Analyst Configuration Tool
Pathway/XM Analyst is a Graphical User Interface (GUI) that is installed separately on
a workstation running Microsoft Windows 95/98/NT. It provides the following:
•
A method for configuring Pathway/XM environments using a series of interactive
screens. Based on the information you enter for various fields, the tool builds a
relational database on your terminal containing all the appropriate configuration
parameter values. You can modify these values, as needed.
When you are ready, Pathway/XM Analyst generates a configuration source file
ready to transfer to the system in which the PXMCFG utility is to run. You use
PXMCFG to generate the SuperCTL file, as usual.
•
Version control that allows you to create and retain multiple versions of a given
Pathway/XM environment. This feature allows you to manage multiple
Pathway/XM environment configurations. The Pathway/XM Analyst tracks and
maintains version numbers. You can create new configuration environments by
copying existing versions then modifying the values or by entering values from
scratch. You can generate a configuration source file from any version.
•
A visual display of the workload and resource distribution generated by any
configuration you defined using this tool. After you enter configuration information,
the Pathway/XM Analyst displays the workload distribution and the distribution of
resources. The tool is especially useful for testing changes to the configuration;
when you make changes, graphs show the potential effect of these changes on a
given Pathway/XM node and on the Pathway/XM environment as a whole.
