Intersystem Message
Flows
This subsection describes how to use Inter-System Routing (ISR) to manage the
message flows between computers in a network. When two computers exchange
event messages, an “ISR conversation” is said to be active.
The subsection provides instructions for these tasks:
Starting an ISR conversation
Stopping an ISR conversation
Specifying the class of messages exchanged
Allowing exchange of solicited and unsolicited messages
The subsection also includes message traffic pattern planning considerations and a
discussion of IBM Network Management Vector Transport (NMVT) message
instrumentation.
Starting an ISR
Conversation
Use the ISR ENABLE command to start an ISR conversation. The command takes the
following form:
ISR ENABLE= flow-class [ link-class ]
The flow-class operand specifies the class of messages whose flow is enabled over
the link. If you omit the flow-class operand, all message classes are allowed to
flow over the link. The link-class operand specifies an INMC link over which the
messages are exchanged. For example, to enable the ISR conversation with a link
named “RIO,” issue this command:
ISR ENABLE LINK=RIO
By default, the ISR conversation over an INMC link is enabled. No messages are
routed between the nodes until the INMC link is active. If you omit the link-class
operand, ISR conversations are started over every INMC link defined for your
NonStop NET/MASTER MS system. The conversation cannot begin until you issue
an ISR ENABLE command on both ends of the link.
Stopping an ISR
Conversation
Use the ISR DISABLE command to stop an ISR conversation. The command takes this
form:
ISR DISABLE= flow-class [ link-class ]
The flow-class operand specifies the class of messages whose flow is disabled over
the link specified by the link operand. If you omit the flow-class operand, the
flow of all message classes is disabled for the link. The link-class operand specifies
an INMC link over which messages are exchanged. If you omit the link-class
operand, the flow of messages specified by flow-class is stopped over every INMC
link defined for your NonStop NET/MASTER MS system. For example, to stop the
ISR conversation with a link named “RIO,” issue this command:
ISR DISABLE LINK=RIO
