This article explains how to submit an ad-hoc job for AWS Mainframe Modernization application from AWS console.

Overview

The batch jobs and the associated programs have to be deployed as an AWS Mainframe Modernization application onto the environment to be available for submission. However, there are scenarios when the JCLs have to be modified on the fly and resubmitted on ad-hoc basic. There might be other scenarios when a new JCL (with no associated program change required) has to be submitted. In those use-cases, the Ad-hoc job submission feature of AWS Mainframe Modernization can be used.

Steps to submit an ad-hoc batch job

  1. Upload the ad-hoc job in a folder within the S3 bucket. Here adhoc-jobs is the S3 folder name and ZSORTREC.jcl.groovy is the name of the ad-hoc JCL groovy script created for the AWS Blu Age (Refactored) application. If you need sample refactored batch job, refer to the workshop.
