Terminal Control Process (TCP) Commands

SET TCP Command
These buffers, like any pool buffer, are held only for the time required to perform
the terminal I/O operation.
TERMPOOL bytes
specifies the number of bytes that the TCP allocates in its data area for all terminal
I/O buffers.
The value for bytes is the minimum number of bytes that the TCP allocates for
the pool size. If you omit this attribute, the default is 10,000.
For a TCP that runs the gateway requester program to support Pathway/iTS web
clients, set bytes to 200,000. Otherwise, calculate an appropriate TERMPOOL
value for your configuration by multiplying the number of TERM objects by the size
of the largest terminal input buffer plus the largest UMP message. For example,
with 100 TERM objects, a largest terminal input buffer of 1000 bytes, and a largest
UMP message of 1000 bytes, set the TERMPOOL value to 200,000 bytes
(100*(1000+1000)=200,000).
If you specify a smaller value for TERMPOOL than the above calculation would
provide, make sure to specify a SET TCP TERMPOOL value of at least 25 bytes
greater than the SET TCP TERMBUF value; the TCP requires the additional 25
bytes for pool management.
Considerations
•
Before adding a TCP to the PATHMON configuration file, you must define values
for all of the required attributes listed in this command.
•
If you repeat a SET TCP command with a different attribute value, PATHCOM
uses the last value entered for the TCP attribute.
•
If you specify the user library object file name, then you should make the
GUARDIAN-LIB attribute a standard part of your PATHMON environment startup
procedure; this ensures that the proper object file is always used. If you customize
your user library object file or if you install the file in a location other than
$SYSTEM.SYSTEM.PATHTCPL, then you must remember to update your library
whenever HP adds new procedures to the standard user library. Updating your
library is essential because new versions of the TCP may invoke the new
procedures in the user library.
Note. TERMBUF is not relevant to verbs (for example, the SEND MESSAGE verb) used with
the IDS facility.
Note. The pool space value allocated for TERMPOOL is the value you configure rounded up
to the next highest multiple of 4.
