Pausing a Task

2. In the displayed Pause Task dialog box, select Pause log capturing and click Yes.
   

   • After the task is paused, the status of the task becomes Paused.
   • After you select Pause log capturing, the DRS instance will no longer communicate with the source and destination databases. If the pause duration is too long, the task may fail to be resumed because the logs required by the source database expire. It is recommended that the pause duration be less than or equal to 24 hours.
