Course Content

TWSzOS Overview
What TWSzOS is, what it does and how it does it.
Describe TWSzOS, its components and how they work together.
Discuss the link to TWS for distributed & End-to-End Scheduling.

TWSzOS Databases 1
Calendar, Period and Workstation.
Describe these databases and use in scheduling work and logically representing the data centre (includes laboratory).

TWSzOS Databases 2
Application & Job Description.
How to define work in the Application and Job Description databases (includes laboratory).

TWSzOS Planning 1
Long Term Plan.
A new Long Term Plan is created so attendees can check and correct their scheduling instructions defined in previous laboratories (includes laboratory).

TWSzOS Planning 2
Current Plan.
A new current plan is created.
Applications created and scheduled in previous laboratories start running and attendees observe/manage jobs and correct/rerun any that fail (includes laboratory).

Describe how TWSzOS work can be controlled from outside TWSzOS by changing the status of work stations or special resources, and how to add non-scheduled applications into the Current Plan (includes laboratory).

Automatic Recovery
Automatic Recovery statements.
Automatic Recovery (AR) will attempt to correct and rerun failed jobs, this topic explains how to code and use AR statements (includes laboratory).

Restart & Cleanup
Catalog management and step-level restarts.
Restart & Cleanup attempts to reset datasets ready for a job rerun and can be combined with a step level restart, this topic covers the dialog panels that manage this function (includes laboratory).

JCL Automation
