SET TCP
If you omit this attribute, the default is 2000 bytes.
A TCP uses this number and the value for the MAXTERMDATA attribute to
allocate the size of the context areas (Slot 0 and Slot 1) for its terminals.
For a TCP that runs the gateway requester program to support Pathway/iTS web
clients, specify a value of 32000.
MAXSERVERCLASSES number
specifies the maximum number of server classes with which a TCP can
communicate simultaneously.
number must be a value from 0 through 4095, where 4095 is the total allowed for
all PATHMON-controlled objects. If you omit this attribute, the default is a value
calculated by the PXMCFG process.
If TCP processes created from this template need to communicate with server
processes in other, external, Pathway/XM environments, you must set the value of
MAXSERVERCLASSES high enough to allow for these extra server classes.
MAXSERVERPROCESSES number
specifies the maximum number of links a TCP can have to all servers in all server
classes.
number must be a value from 0 through 4095, where 4095 is the total allowed for
all PATHMON-controlled objects. If you omit this attribute, the default is a value
calculated by the PXMCFG process.
If TCP processes created from this template need to communicate with server
processes in other, external, Pathway/XM environments, you must set the value of
MAXSERVERPROCESSES high enough to allow for these extra server processes.
MAXTERMDATA bytes
specifies the number of bytes that a TCP allocates for context data for each terminal.
The TCP uses this value and the value of MAXREPLY to determine the size of a
terminal’s slot areas. (Slot 0 and Slot 1 are the same size.)
The maximum value is 2147483647 bytes. The minimum value is 2804 bytes if the
NONSTOP attribute is set to 1. If you enter a value that is less than 2804 bytes and
the NONSTOP attribute is set to 1, the PATHMON process automatically increases
the value to the minimum value. There is no minimum value if the NONSTOP
attribute is set to 0.
If you omit this attribute, the default is 8000 bytes.
After running a TCP, check the PXMCOM STATS TERM display (the AREA
INFO: MAX SIZE, DATA value) to find the actual size of the context data area that
the TCP allocates for a terminal.
For a TCP that runs the gateway requester program to support Pathway/iTS web
clients, specify a value of 200000.
