Specifying Process Names for Direct Server
Processes
Among the file attributes that you can specify with ASSIGN are disk extent size, access
exclusion mode, file code, and record and block size.
PARAM
PARAM assigns a string value to a parameter name, which the PATHMON process then
sends in a PARAM message to each server process as it starts. You can include multiple
PARAM specifications for a server class, just as you can include multiple ASSIGN
specifications. If the NONSTOP attribute is set to ON, the PATHMON process
automatically adds a PARAM for the backup CPU to the PARAM message.
IN and OUT
IN specifies the name of the input file passed to the server in the startup message. It can
be a DEFINE name. If you omit this attribute, spaces are passed to the server.
OUT specifies the name of the output file passed to the server in the startup message. It
can be a DEFINE name. If you omit this attribute, spaces are passed to the server.
STARTUP
STARTUP specifies a character string sent to the server in the startup message.
VOLUME
VOLUME specifies the volume and subvolume names to be passed to each server
process in the startup message. If you omit this attribute, the volume and subvolume
names passed in the startup message are determined as follows:
•
If the DEFAULT attribute is specified for the associated server NODE object, the
volume and subvolume specified in that attribute is used.
•
Otherwise, the volume and subvolume used are the defaults in effect when the initial
PXMCOM START PATHWAY command was issued.
Specifying Process Names for Direct Server Processes
When you configure a direct server class, you can use the PROCESS attribute to specify
process names for individual server processes. In the Pathway/XM environment, you
should assign such names only if you have existing processes outside the Pathway/XM
environment that need to refer to server processes by name. Otherwise, you should
allow Pathway/XM to assign all server-process names.
The PXMCOM START SERVER command does not allow you to start individual
server processes explicitly. However, if you have assigned server process names in your
configuration, PXMCOM uses these names, rather than names it assigns, when it starts
server processes in response to a START SERVER command.
Configuring Dummy Distributed Server Classes for Future Expansion
If desired, you can configure dummy SERVER objects for distributed server classes so
that you can add new server capabilities later without rerunning PXMCFG. For
