Advanced Configuration and Power Interface (ACPI)

Windows supports the Advanced Configuration and Power Interface (ACPI) standard. This enables Windows users with ACPI enabled hardware to stop and restart channels when the system enters and resumes from suspend mode.

Use the ACPI IBM® MQ properties page from the IBM MQ Explorer to specify how IBM MQ is to behave when the system receives a suspend request.

Note that the settings specified in the ACPI IBM MQ properties page are applied only when the Alert Monitor is running. The Alert Monitor icon is present on the taskbar if the Alert Monitor is running.

DoDialog= Y | N: Displays the dialog at the time of a suspend request.
DenySuspend=Y | N: Denies the suspend request. This is used if DoDialog=N, or if DoDialog=Y and a dialog cannot be displayed, for example, because your notebook lid is closed.
CheckChannelsRunning=Y | N: Checks whether any channels are running. The outcome can determine the outcome of the other settings.

The following table outlines the effect of each combination of these parameters:

DoDialog

DenySuspend

CheckChannels Running

Action

Accept the suspend request.

Deny the suspend request.

If any channels are running deny the suspend request; if not accept the request.

Display the dialog (see Note ; accept the suspend request). This is the default.

If no channels are running accept the suspend request; if they are display the dialog (see Note ; accept the request).

Display the dialog ( Note ; deny the suspend request).

If no channels are running accept the suspend request; if they are display the dialog ( Note ; deny the request).

Note: In cases where the action is to display the dialog, if the dialog cannot be displayed (for example because your notebook lid is closed), the DenySuspend option is used to determine whether the suspend request is accepted or denied.
