Creating and Running a z/OS Task
Before You Begin
The z/OS task allow you to run a platform-specific application on a z/OS machine. To run a z/OS task, you must first complete the following tasks:
- Install Universal Agent for z/OS on a z/OS machine.
- Launch the Agent. When the Agent connects with the Universal Controller, it automatically creates an Agent resource definition in the database.
- Optionally, customize the Agent heartbeat and log levels, as described in z/OS Agent Details Field Descriptions.
Built-In Variables
The following built-in variables can be used in a z/OS task to pass data where appropriate:
