UMP Configuration Parameters
UMP Configuration Parameters
The following PATHCOM configuration parameters support the processing of
unsolicited messages:
•
SET TERM MAXINPUTMSGS number
Specifies the total number of unsolicited messages that can be queued by the TCP
for a particular requester at any one time. When that number is reached, the TCP
rejects all subsequent unsolicited messages addressed to that requester until the
requester replies to one of its currently queued messages. This parameter is
particularly useful for ensuring that no single requester can consume a TCP's entire
space for unsolicited-message processing.
•
SET TCP MAXINPUTMSGS number
Specifies the total number of unsolicited messages that a particular TCP can have
queued at any one time for all its requesters. When that number is reached, the TCP
rejects all subsequent unsolicited messages until one of its requesters replies to a
currently queued message.
•
SET TCP MAXINPUTMSGLEN number
Specifies the maximum-size unsolicited message (in bytes) that the TCP will accept.
Messages that are longer than the maximum length are rejected by the TCP with an
appropriate error code. The specified length does not include the standard UMP
message header (currently 40 bytes).
The Compaq NonStop™ Pathway/iTS System Management Manual gives details about
UMP configuration parameters.
Note. The value that you specify for the SET TCP TERMPOOL parameter must be large
enough to accommodate the largest UMP message (or the largest terminal I/O operation).
