How to Update an AutoSys Job

 ### 

AutoSys is a job scheduling software used to automate processes across various platforms. Updating an AutoSys job is essential for changing job configurations, adjusting schedules, or modifying execution parameters. This article will guide you through the process of updating an AutoSys job using Job Information Language (JIL).

#### Steps to Update an AutoSys Job

1. **Identify the Job Name**

   Before updating a job, you need to know the name of the job you want to modify. Use the `autorep` command to check the current job definition and its attributes. 

   ```bash

   autorep -J <job_name>

   ```

   This command displays details about the specified job, allowing you to identify the parameters that need updating.

2. **Extract the Current Job Definition**

   You can extract the job definition to a file, which makes it easier to modify the job parameters. Use the `autorep` command with the `-q` option to create a JIL file.

   ```bash

   autorep -J <job_name> -q > job_definition.jil

   ```

3. **Edit the JIL File**

   Open the `job_definition.jil` file in a text editor. Make the necessary changes to the job definition. Common parameters you might update include:

   - **Command**: The command or script the job executes.

   - **Start Times**: When the job should run.

   - **Conditions**: Dependencies or conditions that must be met for the job to run.

   - **Notifications**: Email alerts for job failures or completions.

   For example, if you want to change the command for the job, find the line that starts with `command` and update it:

   ```jil

   update_job: <job_name>

   command: "/new/path/to/script.sh"

   ```

4. **Validate the JIL File**

   Before updating the job in AutoSys, it’s important to validate the JIL syntax to avoid errors. Use the `jil` command to validate the changes.

   ```bash

   jil < job_definition.jil

   ```

   If there are no syntax errors, the command will execute without any output.

5. **Update the Job in AutoSys**

   Once validated, you can use the `jil` command to update the job in the AutoSys database. Simply execute the JIL file again:

   ```bash

   jil < job_definition.jil

   ```

   This command will update the job with the modified parameters.

6. **Verify the Update**

   After the update, verify that the job has been updated successfully. Use the `autorep` command again:

   ```bash

   autorep -J <job_name>

   ```

   Check the output to ensure the changes have been applied correctly.

#### Example of Updating an AutoSys Job

Here’s a simple example of updating an AutoSys job named `DATA_BACKUP`. Suppose you want to change the command it executes and adjust the start time.

1. **Extract the Current Definition**:

   ```bash

   autorep -J DATA_BACKUP -q > data_backup.jil

   ```

2. **Edit the `data_backup.jil`**:

   ```jil

   update_job: DATA_BACKUP

   command: "/new/backup_script.sh"

   start_times: "12:00"

   ```

3. **Validate and Update**:

   ```bash

   jil < data_backup.jil

   ```

4. **Verify**:

   ```bash

   autorep -J DATA_BACKUP

   ```

#### Conclusion

Updating an AutoSys job involves identifying the job, extracting its current definition, making necessary modifications, validating the changes, and updating the job in the AutoSys environment. By following these steps, you can efficiently manage and adjust your job schedules to meet changing business needs. Always ensure to verify the changes to confirm the job operates as expected after the update.
