z/OS Guest Consoles

If you intend to use CA Automation Point to manage a z/OS session that runs as a guest under z/VM, you may need to configure the z/VM BREAK key to ensure that the z/VM console session operates smoothly. The BREAK key allows you to toggle between the z/VM console and the z/OS console.

You cannot send a key operation intended for z/OS using the key configured as the z/VM BREAK key because z/VM intercepts the key first. CA Automation Point requires that the BREAK key be set to Clear, which neither CA Automation Point nor the operator uses.

Note: The default z/VM BREAK key is PA1, which CA Automation Point does not use; however, a z/OS operator can use the PA1 key to retrieve and reissue the previous z/OS command when the console is under manual control. IBM suggests setting the z/VM BREAK key to a less commonly used key, such as PA2; however, the CA Automation Point MCS console scripts use the PA2 key to reset the console if an error state occurs.
