2.10 Troubleshooting agent failures that might affect manager processing
When you use submit jobs, you can use emergency commands to restore the system if an agent failure affects manager processing.
Using the emergency commands, you can check the job execution status if a failure occurs on an agent and take appropriate action. Because the emergency commands request job execution control over a communication path that is not used for normal commands, you can execute the commands immediately.
- Important
-
Use the emergency commands only to restore the system if an agent failure affects the processing of the manager. If you use the emergency commands frequently, JP1/AJS3 might not be able to respond to failures.
The following table describes the commands executable as emergency commands. When using a command as an emergency command, add the -em option.
