Use SET AUTOPOLL to control how <strong>CP</strong> detects changes to virtual autopolling<br />

channel programs:<br />

v The system itself tests for the change<br />

v Your virtual machine notifies the system of the change.<br />

Note: In general, the guest operating system issues the notifying comm<strong>and</strong> without<br />

your intervention.<br />

ON<br />

OFF<br />

controls whether <strong>CP</strong> tests for changes to virtual autopolling channel programs.<br />

ON indicates that your virtual machine must notify <strong>CP</strong> when a change is made<br />

to a virtual autopolling channel program. OFF indicates that <strong>CP</strong> tests for<br />

changes to virtual autopolling channel programs.<br />

1. Do not enter this comm<strong>and</strong> arbitrarily. If you enter the comm<strong>and</strong> while a guest<br />

operating system is running, you may cause the system to stop or to end<br />

abnormally.<br />

2. If SET AUTOPOLL ON is required for your virtual machine, the operating<br />

system running in your virtual machine is using DIAGNOSE X'28' to notify the<br />

system whenever a virtual autopolling channel program has been modified.<br />

3. SET AUTOPOLL OFF is required if the operating system running in your virtual<br />

machine does NOT use the DIAGNOSE X'28' interface.<br />
