Writing a PXMCFG Source File
Therefore, after you run PXMCFG, it is recommended that you review the last page
(summary page) of your PXMCFG output and compare it with the SYSGEN
configuration for your application system. If the number of processes per CPU in your
SYSGEN configuration is inadequate, increase the parameter value in SYSGEN.
To ensure that Pathway/XM can create as many processes as needed, you should also set
the HIGHPIN attribute to ON for all the TCP templates and SERVER objects (server
classes) in your configuration.
Writing a PXMCFG Source File
You create objects in your Pathway/XM configuration by defining their attributes with
PXMCFG statements. These attributes describe how each object relates to other objects
and how it should be managed in the Pathway/XM environment. The attributes for a
server class, for instance, specify the server-class name, the server-class type
(distributed, replicated, or direct), the relative execution priority for processes in the
server class, the name of the program the server processes run, and other characteristics.
Using the COMMENT Statement
The COMMENT statement allows you to add comment text to your source file.
A comment line begins with the text COMMENT, in any combination of uppercase and
lowercase letters, followed by a space. (The space character is required.) All text
following the word COMMENT and the space is ignored by PXMCFG when processing
the source file, as in the following example:
COMMENT This configuration was created on October 15, 1997.
Using comments in your configuration files makes them easier to understand and to
modify later as needed. For the syntax of the COMMENT statement, refer to
COMMENT on page 10-14.
Including Multiple Source Files in a Configuration
The INCLUDE statement allows you to include multiple files of PXMCFG statements
in a single Pathway/XM configuration. PXMCFG replaces an INCLUDE statement
with the contents of the specified file.
For example, the following sequence of statements results in a configuration made from
the combination of the statements in the files named $DATA.CFG.ORDRAPP,
$DATA.CFG.QUERYAPP, and $DATA.CFG.BILLING:
INCLUDE $DATA.CFG.ORDRAPP
INCLUDE $DATA.CFG.QUERYAPP
INCLUDE $DATA.CFG.BILLING
For the syntax of the INCLUDE statement, refer to INCLUDE on page 10-17.
Using the SET and ADD Statements
Whether you configure objects for a new environment or add objects to a restarted
environment, the procedure is the same, as follows:
