AutoSys Job Re-run with Fixed Delay

 

AutoSys Job Re-run with Fixed Delay

Introduction: AutoSys is a comprehensive job scheduling system used by organizations to manage and automate tasks across multiple platforms. One of the critical features of AutoSys is its ability to re-run jobs with a fixed delay in case of failure or other conditions. This feature ensures that jobs are retried automatically, reducing the need for manual intervention and increasing system reliability.

Understanding Job Re-runs in AutoSys: In AutoSys, jobs can be configured to re-run automatically after a failure or under specific conditions. This is particularly useful in scenarios where transient issues may cause a job to fail temporarily, and a re-run after a short delay could lead to successful completion.

Implementing Fixed Delay Re-runs: To configure a job in AutoSys to re-run with a fixed delay, you can use the max_run_alarm and alarm_if_fail attributes along with a box job or a command job. Here's how to set it up:

1. Using max_run_alarm: The max_run_alarm attribute specifies the maximum time (in minutes) that a job is allowed to run. If the job exceeds this time, it will be terminated and can be set to re-run.

2. Using alarm_if_fail: The alarm_if_fail attribute triggers an alarm if the job fails. You can combine this with an AutoSys box job that contains logic to handle re-runs.

3. Using exit_code_reposts and exit_code_eq: These attributes allow you to specify conditions under which a job should be re-run based on its exit code.

Example JIL Script: Below is an example of a JIL (Job Information Language) script that demonstrates how to set up a job to re-run with a fixed delay:

jil:

insert_job: sample_job
job_type: c
command: /path/to/your/command
machine: your_machine_name
owner: your_username
permission: gx,ge
date_conditions: 1
days_of_week: all
start_times: "08:00"
alarm_if_fail: 1
max_run_alarm: 5
max_exit_success: 0
run_window: "08:00-20:00"

# Setting up the re-run
condition: s(sample_job) & done(sample_job)
box_success: n
box_failure: y

# Adding a delay
description: "Job will re-run with a 5-minute delay if it fails."

In this example, if sample_job fails, it will trigger the alarm_if_fail attribute, and AutoSys will handle the re-run with a fixed delay as specified by the max_run_alarm attribute.

Best Practices:

• Monitor Job Failures: Ensure that you have proper monitoring in place to track job failures and re-runs. This helps in identifying patterns and potential issues in the system.
• Set Appropriate Delays: Choose a delay that is reasonable for your system. Too short a delay may cause unnecessary load, while too long a delay may result in delays in dependent jobs.
• Use Exit Codes Wisely: Customize re-runs based on specific exit codes to avoid unnecessary re-runs for non-recoverable errors.

Conclusion: AutoSys provides robust features for managing job re-runs with a fixed delay, allowing for greater automation and reliability. By configuring jobs with attributes like max_run_alarm and alarm_if_fail, you can ensure that transient issues are handled efficiently, reducing downtime and manual intervention.
