Extension architecture for WebSphere Message Broker Exit

When configuring WebSphere Message Broker activities that are the first input node of a broker flow, no terminal can be associated to the activity touchpoint. Therefore, you do not specify a terminal for input associations for that activity in the transaction pathway.

If you specify the -out terminal in the figure below, then any transactions that go through the _failure or _catch terminals are ignored by TrueSight Middleware and Transaction Monitor. Additionally, by not identifying the specific terminal, you keep the transaction pathway in TrueSight Middleware and Transaction Monitor simple. You can identify each terminal as a starting point, but doing so would complicate the transaction pathway and require three starting points.

The following figure shows what the transaction pathway looks like in TrueSight Middleware and Transaction Monitor and what should be configured so that all transactions are monitored correctly.

 

  • WMBActivity1:
    • Activity Implementation: Configure the broker name and message flow on the Extension Details tab.
    • Activity in the transaction pathway: Configure the input association (because the transaction is entering the WMB Exit BTM Extension) and define the resource ID to match the name of the node. A terminal should not be specified.
  • WMBActivity2:
    • Activity Implementation: Configure the broker name and message flow on the Extension Details tab.
    • Activity in the transaction pathway: Configure the output association (because the transaction is leaving the WMB Exit BTM Extension) and define the resource ID to match nodein and terminal (where _node is the name of the node).

In summary, you can specify

  • for an input association:
    • the name of the input node of a flow
    • an output terminal of any node in a flow (by NodeName_terminal)
  • for an output association:
    • the input terminal of any node (except the initial input node) of the flow by NodeName_terminal.
