Tableau Server consists of multiple processes managed by TSM. When you stop Tableau Server (e.g., via tsm stop), most application processes halt, but some TSM-specific processes remain active to manage the server's infrastructure. Let's examine each:
* TSM Processes: These include the Administration Controller, Administration Agent, and License Manager, which handle configuration, monitoring, and licensing.
* Application Processes: These include VizQL Server, Backgrounder, Data Server, etc., which deliver Tableau's core functionality and stop when the server is stopped.
When tsm stop is executed:
* TheAdministration Controller(port 8850) continues running to manage TSM operations (e.g., restarts, status checks).
* TheLicense Managerremains active to validate licenses and ensure compliance, even when the server is offline.
* Application processes like VizQL Server and Backgrounder shut down, as they're tied to user-facing services.
* Option B (License Manager): Correct. It persists to handle licensing tasks, ensuring the server can restart without license issues.
* Option D (Administration Controller): Correct. It's the core TSM process, always running to accept commands and manage the server state.
* Option A (VizQL Server): Incorrect. VizQL stops, as it renders visualizations for users-an application process tied to active server operation.
* Option C (Backgrounder): Incorrect. Backgrounder stops, as it processes background tasks (e.g., extract refreshes), which halt when the server is down.
Why This Matters: Understanding which processes persist helps administrators troubleshoot and manage server lifecycle events effectively.
