Managing Ensemble Productions - InterSystems Documentation

Ensemble Management Portal
When discrepancies such as this arise, the Update Production command becomes available on the home page. Click
it, to update the production and resolve the discrepancy. Ensemble displays a confirmation message. Click OK to return
to the [Ensemble] home page.
Alternatively, you can cause the production to update itself automatically. When you take this approach, the Update
Production command never appears. To do this:
– Start the Business Service Wizard. For instructions, see the Adding a Business Service to a Production section in
the “Business Services” chapter of Developing Ensemble Productions. When the wizard displays, choose Other,
and for the Service Class choose Ens.ProductionMonitorService. You may accept the default values for the other
settings. Click OK. This adds a production monitor service to the production.
– View the production configuration diagram on the [Ensemble] > [Productions] > [Configuration] page. Select the
new production monitor service and configure its General Settings and Specific Settings. For details, see the
“Business Service Settings” section in the “Configuration” chapter. The Call Interval setting controls how frequently,
in seconds, the production monitor service checks to see if there is a discrepancy between the production
as defined in the code, and the status of the running production. Each time it finds such a discrepancy, the production
monitor service updates the production to resolve it.
• Recover — Appears on the home page if a production has a status of Troubled due to some unexpected program error.
Click Recover to clean up the troubled instance of the production so that you can run a new instance when you are
ready.
1.4.3 Job Table
The Ensemble home page Job table displays the following data fields:
• Total Jobs Running — The number of system jobs that have been allocated to pools for use by business hosts within
this production. This number reflects a current snapshot when you refresh the home page.
Each time a business service, business process, or business operation needs to do work, it starts a system job in which
to complete its tasks. This job comes either from a private pool of jobs belonging to the business service, business
process, or business operation, or (in the case of a business operation) it may come from the public actor pool for the
production. When the task is done, the job returns itself to the pool of jobs from which it came.
A production might need to start and stop several different jobs to complete a single requests. The details depend (in
part) on whether requests are made synchronously or asynchronously. For example, if a job is required to wait, the job
returns itself to its pool during the wait time to free up that resource.
• Jobs OK, Jobs Inactive, Jobs of Other Status — The number of jobs with a status of OK, Inactive, or some other value,
respectively.
If you click the Job table title on the Ensemble home page, the [Ensemble] > [Jobs] page displays — the same result as
clicking Job on the Ensemble menu.
1.4.4 Log Table
The home page Log table displays the following data fields:
• Last Error Time — The date and time of the most recent entry in the Total Error Count.
• Total Error Count — The number of error entries that have been written to the event log since this production was last
started. Errors that were recorded during a previous run of this production or of any other production might still reside
in the event log as entries, but are not included in the Total Error Count.
