Advanced Configuration and Power Interface (ACPI)

Windows 2000 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 WebSphere MQ properties page from the WebSphere MQ Explorer, to specify how WebSphere MQ is to behave when the system receives a suspend request.

Note that the settings specified in the ACPI WebSphere MQ properties page are applied only when the Alert Monitor is running. The Alert Monitor icon is present on the task bar 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 laptop 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
N N N Accept the suspend request.
N N Y Accept the suspend request.
N Y N Deny the suspend request.
N Y Y If any channels are running deny the suspend request; if not accept the request.
Y N N Display the dialog (see note below; accept the suspend request). This is the default.
Y N Y If no channels are running accept the suspend request; if they are display the dialog (see note below; accept the request).
Y Y N Display the dialog (see note below; deny the suspend request).
Y Y Y If no channels are running accept the suspend request; if they are display the dialog (see note below; deny the request).

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