System Manager executes several scheduled processes in the background. When System Manager shuts down, the system must stop the processes that System Manager runs in the background. This is to ensure that the system is stable and does not contain incomplete data in any data store when System Manager starts the next time. The system must also ensure that the background process that stops does not leave the system in an unstable state.
The shutdown process stops all running jobs and then shuts down System Manager.
Note:
You cannot cancel the process after you select the shutdown process.
To ensure that System Manager shuts down completely, the shutdown feature provides a user interface that displays all scheduled jobs that are running on System Manager and active user sessions. Based on the criticality and priority of scheduled jobs, the administrator can shut down the system immediately or wait for the scheduled jobs to complete.
If the administrator chooses to shut down the system, the shutdown service performs the following actions:
Sends the shutdown notification to active users so that users can commit or rollback the operation. The shutdown framework waits for the specified grace period that the administrator sets for active users to complete the operations.
Sends the shutdown signal to the Scheduler of System Manager to interrupt the running jobs. Scheduler service must not start any new scheduled jobs.
Blocks access to the System Manager web console during a shutdown. After the grace period, the system disallows new logins. The system stops all existing sessions when the shutdown begins and redirects the sessions to the Login page. The system displays Shutdown in progress message on Login page.
Logs an audit message indicating that a request for shutdown is made.
Makes an entry in a file about the shutdown request. The system uses the shutdown request information to display the shutdown history.
Shuts down System Manager.
If any of the steps fail, the system logs a message and performs the next step.
Administrator can shut down System Manager from the command line interface or System Manager web console.
