SET TCP
MAXINPUTMSGLEN number
specifies the maximum length in bytes of any unsolicited message that a TCP
accepts. This does not include the header length.
number can be a value from 0 through 6000 bytes. If you omit this attribute, the
default is 133 bytes. (Note that any bytes you specify in excess of the default are
taken from the terminal pool area.)
TCP processes reject messages received that exceed MAXINPUTMSGLEN.
MAXINPUTMSGS number
specifies the maximum number of unsolicited messages that each TCP using that
TCP template queues at any one time for any TERM object under its control. When
this attribute is exceeded, all arriving messages are rejected by the TCP until a
terminal issues a REPLY to process messages already in the queue.
number must be a value from 0 to 2045. If you omit this attribute, the default is 0.
The higher the value set for MAXINPUTMSGS, the greater the buffer size that is
required, therefore the fewer the number of terminals that can be configured for the
TCP. During the configuration calculation process, the higher the value set for
MAXINPUTMSGS, the more TCP processes the PXMCFG process creates.
If MAXINPUTMSGS is set to 0, terminals associated with the TCP are not able to
accept unsolicited messages. A value of 0 causes the PXMCFG process to disregard
any of the above constraints when determining the number of TCP processes.
MAXPATHWAYS number
specifies the maximum number of external PATHMON processes (other PATHMON
processes either within the same Pathway/XM environment or in different
Pathway/XM environments) that a TCP can communicate with at one time. The
value specified is the maximum PATHMON processes within this Pathway/XM
environment and in other Pathway/XM environments that need to communicate with
the TCP.
number must be a value from 0 through 4095. If you omit this attribute, the value
of MAXPATHWAY is 0 and attempts by the TCP to access a server process in
another PATHMON environment fail.
MAXREPLY bytes
specifies the maximum number of bytes permitted for an outgoing SEND message
or a server reply message. bytes must be a value from 0 through 32767.
Set the value for MAXREPLY to the larger of either:
•
The longest outgoing message (in bytes) from any SEND verb in any terminal
under control of this TCP.
•
The longest reply (in bytes) possible from any server process replying to a
SEND verb from any terminal under control of this TCP.
