Pausing tasks in Talend Administration Center
Before backing up the project administration database for migration purposes, it is best practice to pause all currently active tasks.
This will prevent the Job Conductor from trying to run those tasks while the database migration process is running. Once the backup is complete, unpause all the tasks.
Procedure
- Access Talend Administration Center.
- In the Menu tree view, click Job Conductor to display the list of all currently active and scheduled tasks.
- Click Pause.
