Productions • Last Stop Time — The date and time when the production was last stopped. Table 4–1: Production Status Values Status Value Running Stopped Suspended Troubled Row Color Light green Light gray Orange Light gray Meaning When a production has been started and is operating normally, it has a status of Running. This is an acceptable state. A production acquires a status of Stopped when, at the end of the shutdown sequence, all of its queues are free of synchronous messages. This is an acceptable state. A production acquires the Suspended status if, at the end of the shutdown sequence, some queues still contain synchronous messages, waiting for a response. Depending on how the production has been designed, this may or may not indicate a problem. You may start a Suspended production. Starting the production again may permit the waiting messages to be processed. However, if you start the Suspended production, and more messages arrive while those in front of them in the queue cannot be resolved, queues may simply continue to fill. In that case you must investigate to discover why the incoming messages never complete. A production acquires a status of Troubled if Ensemble is stopped but the production did not shut down properly. This can happen if you restarted Ensemble or rebooted the machine without first stopping the production. When a production acquires a Troubled status, a Recover command appears on the Ensemble Management Portal home page (the [Ensemble] page). Click this command to clean up the troubled instance of the production so that you can run a new instance when you are ready. To the right of each entry in the Productions table are four of the following five commands: • Click Configure to display the configuration diagram. This is a graphical inventory of the business hosts in the production, organized into three columns: business services, business processes, and business operations. Each item in the diagram displays runtime status indicators. You can select individual elements to monitor and edit the details of performance and configuration. For details about this diagram, see the “Configuration” chapter. • Click Start to Start the production; offered if the production is stopped. • Click Stop to Stop the production; offered if the production is running. • Click Documentation to view or generate configuration documentation for this production in HTML format. 4.2 Starting a Production You can start an Ensemble production from various pages in the Ensemble Management Portal, including the Productions page.
