Terminal Control Process (TCP) Commands

SET TCP Command
If you omit this attribute, the default is in the format $Znnn.
PROGRAM file-name
specifies the TCP object file name (usually $SYSTEM.SYSTEM.PATHTCP2).
If you do not specify a node name, the default node for file-name expansion can be
affected by several factors, including values you specify for the TS/MP CMDVOL
command and the NODEINDEPENDENT attribute of the NonStop TS/MP SET
PATHWAY command. For details, see Specifying Node Independence on page 2-5.
If you omit this attribute, the default is $SYSTEM.SYSTEM.PATHTCP2.
SENDMSGTIMEOUT { ON | OFF }
specifies whether or not the TCP should filter out 3161 timeout error messages
when the ON ERROR clause is used with a SEND MESSAGE statement.
If you omit this attribute, the default is ON.
SERVERPOOL bytes
specifies the number of bytes that the TCP allocates for I/O requests and replies
between the SCREEN COBOL programs and server processes. Space is also
allocated for receiving and sending unsolicited messages.
The value for bytes is the maximum number of bytes that the TCP allocates for a
server I/O buffer and must be at least the size of the largest predefined server
reply message.
For a TCP that runs the gateway requester program to support Pathway/iTS web
clients, set the value of this attribute to 40,000 bytes. Otherwise, the suggested
range is 10,000 to 30,000 bytes. The minimum value is 32 bytes. If you omit this
attribute, the default is 20,000 bytes.
The maximum useful value for SERVERPOOL is the length of the largest request
or reply multiplied by the number of terminals that the TCP controls. If the program
uses unsolicited message processing (UMP), add in the value of the maximum
concurrent UMP I/O operation multiplied by the maximum UMP message size.
ON The TCP does not filter out 3161 timeout messages.
OFF The TCP filters out 3161 timeout messages when the ON ERROR clause is
used with a SEND MESSAGE statement.
When the ON ERROR clause is used with a SEND MESSAGE statement, only
the first 3161 timeout encountered by each TCP configured under a PATHMON
is logged. An additional 3161 timeout is logged when the primary TCP fails and
the backup TCP takes over and encounters the timeout. The TCPs filter out all
other 3161 timeout errors. If the ON ERROR clause is not used and a 3161
timeout occurs, the corresponding terminal is suspended after the timeout is
logged.
