How to Restart AutoSys Agent in Linux

 ### 

AutoSys is a popular job scheduling software that helps manage and automate jobs across different platforms. Sometimes, it may be necessary to restart the AutoSys agent to apply configuration changes, troubleshoot issues, or recover from failures. This article provides a step-by-step guide on how to restart the AutoSys agent on a Linux system.

#### Prerequisites

Before restarting the AutoSys agent, ensure you have:

- Access to the Linux system where the AutoSys agent is installed.

- Sufficient permissions (typically root or an account with sudo privileges).

- The AutoSys agent's configuration file and any relevant job details at hand.

#### Steps to Restart the AutoSys Agent

1. **Open a Terminal**

   Log in to your Linux server using SSH or directly access the terminal.

2. **Check the AutoSys Agent Status**

   Before restarting, it's good practice to check the current status of the AutoSys agent. You can do this by executing the following command:

   ```bash

   autosys -v

   ```

   This command will display the version of AutoSys and confirm that the agent is running.

3. **Stop the AutoSys Agent**

   To stop the AutoSys agent, use the following command:

   ```bash

   /etc/init.d/auto_sys stop

   ```

   Alternatively, if you are using `systemd`, you can use:

   ```bash

   sudo systemctl stop autosys

   ```

   Verify that the agent has stopped by running:

   ```bash

   ps -ef | grep autosys

   ```

   If no processes related to AutoSys are returned, the agent has stopped successfully.

4. **Start the AutoSys Agent**

   Once the agent is stopped, you can start it again using the following command:

   ```bash

   /etc/init.d/auto_sys start

   ```

   Or with `systemd`:

   ```bash

   sudo systemctl start autosys

   ```

   To ensure that the agent is running correctly, execute:

   ```bash

   ps -ef | grep autosys

   ```

   You should see the AutoSys processes running.

5. **Check AutoSys Job Status**

   After restarting the agent, check the status of your jobs to ensure everything is functioning as expected. You can use the following command to see the job status:

   ```bash

   autorep -J <job_name> -q

   ```

   Replace `<job_name>` with the name of your job.

6. **Verify the Agent Logs**

   For troubleshooting and verification, check the AutoSys agent logs. Typically, logs are located in the `/var/opt/CA/WorkloadAutomationAE/` directory. Use the following command to view the log files:

   ```bash

   tail -f /var/opt/CA/WorkloadAutomationAE/logs/autosys.log

   ```

   Look for any error messages or logs indicating successful job executions.

#### Conclusion

Restarting the AutoSys agent in Linux is a straightforward process that involves stopping and starting the service. It is an essential task for maintenance and troubleshooting. Always ensure to monitor job statuses and logs after the restart to confirm that the system is functioning correctly.
