JOC Cockpit Implementation Architecture
- JOC Cockpit can be operated in the following modes:
- single instance,
- active-passive clustered instance with a primary instance and backup instance,
- active passive clustered instance with a primary instance and any number of backup instances.
- The JOC Cluster Service
- manages a number of backend services:
- Job Streams Service: manage job starts, monitor tasks and calculate events for dependency management.
- History Service: retrieve the job execution and log output of jobs executed with Agents.
- Daily Plan Service: submit orders for the daily plan to JobScheduler Master.
- Monitor Service: check execution history for events that users should be notified about.
- operates backend services for active or passive mode:
- in active mode any of the services will perform active tasks, e.g. the Job Streams Service will start tasks,
- in passive mode any of the services will report status information about the result of active tasks.
- guarantees service execution
- for the Active JOC Cockpit instance in service active mode,
- for any Passive JOC Cockpit instance in service passive mode.
- forwards service execution requests originating from a Passive JOC Cockpit instance to the Active JOC Cockpit instance.
- manages a number of backend services:
