SET TCP
PRI priority
specifies the execution priority at which a TCP runs.
priority can be a value from 1 through 199. If you omit this attribute, the default
is the priority set for the NODE object to which this TCP is associated.
PROGRAM file-name
specifies a TCP object file name (usually $SYSTEM.SYSTEM.PATHTCP2).
Defaults for file name expansion are based on the values of the SYSTEM and
DEFAULT attributes of the associated NODE object.
If you omit this attribute, the default is $SYSTEM.SYSTEM.PATHTCP2.
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.
The suggested range for this attribute is 10000 to 30000 bytes. The minimum value
is 32 bytes. If you omit this attribute, the default is 20000 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.
For a TCP that runs the gateway requester program to support Pathway/iTS web
clients, specify a value of 40000.
STATS { ON | OFF }
specifies whether a TCP gathers resource usage and system performance statistics.
If you omit this attribute, the default is OFF.
This attribute works in conjunction with the PXMCOM STATS command, which
displays TCP, TERM, and SERVER object statistics gathered by the TCP.
Note. The pool space value allocated for SERVERPOOL is the value you configure
rounded up to the next highest multiple of 4.
ON A TCP gathers statistics.
OFF A TCP does not gather statistics.
