Mainframe, MVS and zOS Discussion

CA-11 is an Automated Rerun and Tracking System. It can be used as an effective management tool in a production environment and as an invaluable tool in a test environment. The objective of CA-11 is to improve resource use and productivity of the Data Center. CA-11 is designed to perform as a Run Handler, and as a Job Tracking System or a combination of both.

There are two types of job execution:

• 1. Production Run – which is the initial execution of a job.
  2. Rerun – which is considered to be an extension or continuation of a production run.

The Run Handler provides the means for automatically handling all MVS catalog maintenance, dataset maintenance, and GDG bias adjustments for job reruns and restarts. It handles step restarts as easily as complete job reruns. The use of step restarts by CA-11, as opposed to complete reruns, and the reduction of reruns greatly improves the productivity of the data center.
