Rulerunner operation

Rulerunner is configured to monitor job queues for jobs to run in the background.

Rulerunner runs in the background as a Windows service. Although you can configure Rulerunner to work with multiple Taskmaster applications, consider the case where it is configured for one application.

Rulerunner monitors the job queue of the application that is looking for jobs it is configured to run. The Taskmaster Web client Monitor tab is used to monitor the queue. But the actual job queue is maintained in the queue table in the Taskmaster engine database. By default, the engine database is a Microsoft Access database is in the root of the application folder. For example, the engine database of the TravelDocs application is C:\Datacap\TravelDocs\TravelDocsEng.mdb.

Attention: Taskmaster supports other database types, including Microsoft SQL Server and Oracle.

Rulerunner polls the job queue every 10 seconds and looks for pending jobs. When it finds a pending job, Rulerunner processes the batch. Upon completion, the batch is ready for the next task in the workflow. In this way, you can move batches through any number of sequential background tasks automatically.
