Configuring TCPs for Pathway/iTS
You have two choices for naming the library object file:
•
You can name the customized library $SYSTEM.SYSTEM.PATHTCPL.
•
You can name the customized library file something other than
$SYSTEM.SYSTEM.PATHTCPL, such as $SKY.KING.USERTCPL.
If you keep the name $SYSTEM.SYSTEM.PATHTCPL for your customized library
file, you need not explicitly configure the library file name. If you use a different name,
you must use a SET TCP statement with the GUARDIAN-LIB option to name the
library file:
SET TCP GUARDIAN-LIB $SKY.KING.USERTCPL
Configuring TCPs for Pathway/iTS
If you are configuring a TCP for use with Pathway/iTS web clients, the gateway
requester program requires that you configure specific values for the following TCP
attributes:
SERVERPOOL 40000
TERMPOOL 200000
TERMBUF 32000
MAXREPLY 32000
MAXTERMDATA 2000000
If these values are not specified, the TERM object threads may be suspended at run
time.
Configuring ROUTER Objects
A ROUTER object represents a listener process that monitors a communication
endpoint of a web client application or an intelligent device socket and distributes the
incoming communication requests to the appropriate TERM objects. The router
establishes a link between the client or requester, the TCP process, and the terminal task
processing that link; thereafter, the TCP communicates directly with the terminal task.
This features supports the web clients and IDS requesters managed by Pathway/iTS.
When you configure ROUTER objects, the PXMCFG process automatically calculates
the number of TERM objects and TCP processes needed to support the configured
number of concurrent connections for each router process. The PXMCFG process also
modifies each TERM object by adding a GROUP attribute with the name of the
associated ROUTER object.
Before entering any statements to configure a router, you must first enable the router
support, using the ENABLE ROUTER statement.
Caution. Each time you install a new version of the TCP, you should add your customized
procedures to the new PATHTCPL object library file (be sure you name the new library file the
same name as the former, customized library file). Using the latest PATHTCPL object library
combined with your procedures ensures that there are no incompatibilities between the new
version of the TCP and the PATHTCPL object library.
