After configuring application monitoring you may want to perform routine maintenance tasks on those applications. These tasks may or may not involve stopping the application but may temporarily affect the state of the applications and its dependent components. If there is any change to the application status, Cluster Server (VCS) may try to restore the application state. This may potentially affect the maintenance tasks that you intend to perform on those applications.
If stopping the application is not an option, you can suspend application monitoring and create a window for performing such maintenance tasks. When application monitoring is suspended, VCS freezes the application configuration.
The

During the time the monitoring is suspended, Veritas high availability solutions do not monitor the state of the application and its dependent components. The Veritas High Availability view does not display the current status of the application. If there is any failure in the application or its components, VCS takes no action.
