Defining TCP Attributes
You use the SET TCP and ADD TCP statements to define the TCP attributes for a TCP
template, name the TCP template, and add it to your Pathway/XM configuration.
PXMCFG assigns the specified attributes to all the TCPs it creates from that TCP
template.
Although you use an ADD statement to define a TCP template to PXMCFG, PXMCFG
does not store the TCP template definition in the SuperCTL file. Instead, PXMCFG
uses the template definition internally to configure the individual TCP processes, and
then adds the TCP processes to the SuperCTL file. PXMCFG assigns names to the TCP
processes by appending unique sequence numbers to the TCP template name.
This subsection provides brief definitions of the required and optional attributes you can
configure for a TCP template, gives an example of setting these attributes, and then
describes special considerations for some of the individual attributes.
For the complete syntax of the SET TCP statement, including descriptions of all the
attributes you can set for a TCP object, refer to SET TCP
on page 10-63. For the syntax
of the ADD TCP statement, refer to ADD TCP on page 10-12.
For all TCP templates, the PATHMON process requires you to specify the following
attributes:
In addition to specifying the required attributes, you can either specify or accept default
values for other, optional attributes. Examples of these optional attributes are:
TCLPROG specifies the object library file that the TCPs
search to locate the screen programs for its TERM
objects.
NODE Specifies the client NODE object to be used to
define CPU resources and default process
attributes for the TCPs defined by this TCP
template.
HIGHPIN Specifies whether the TCPs run at high PINs or
low PINs.
PRI Specifies the relative priority at which the TCPs
run.
MAXSERVERCLASSES Specifies the maximum number of server classes
with which each TCP can communicate
simultaneously.
