We have a requirement where we want to be alerted if a flow is stopped. Trying to use the event messages form broker that i have subscribed for to accomplish this.( Please let me know if there is a better way)
i get event messages like this
<Broker uuid="e16d3f10-2301-0000-0080-9b863d9b8027">
<ExecutionGroup uuid="2675a421-2501-0000-0080-fdefb974c890">
<Start>
<MessageFlow uuid="9c661823-2501-0000-0080-91534dd1247d"/>
<MessageFlow uuid="b2661823-2501-0000-0080-91534dd1247d"/>
</Start>
</ExecutionGroup>
</Broker>
how can i find the flow name from the UUID? Tried looking in the broker tables but couldnt find the flow names there.
trying to see if i can keep track of stopped flows and if there is not a consecutive start event then i will alert saying that the flow is stopped.
sounds complex but i guess i dont have a better way of doing this. |

Rather than using anything internal, the CMP will do all of this for you really easily.
Using the AdministeredObjectListener interface, you can elect to receive notifications when message flows start and stop. If necessary, you can also retrieve UUIDs from names and vice versa, but this shouldn't be necessary.
Basic flow for your scenario would be:
(1) Connect to CM (or broker in v7),
(2) get the required MessageFlowProxy object(s),
(3) call MessageFlowProxy.registerListener(), giving it your callback class,
(4) In the callback class's processModify() method, look for notifications where your message flow's 'object.runstate' becomes 'stopped'
The CMP API Exerciser will give you more information on the methods and the exact formats you need to enable this.
The DomainInfo sample (called BrokerInfo in v7) also gives you information on how to register listeners and receive notifications.
Hope this helps.
