The Symantec High Availability tab lets you define and modify settings that control application monitoring with Veritas Cluster Server (VCS). You can define the settings on a per application basis. The settings apply to all systems in a VCS cluster, where that particular application is configured for monitoring.
The following settings are available:
: When you click the or , or links in the Symantec High Availability tab, VCS initiates an application start or stop, respectively. This option defines the number of seconds that VCS must wait for the application to start or stop, after initiating the operation. You can set a value between 0 and 300 seconds for this attribute; the default value is 30 seconds.
If the application does not respond in the stipulated time, the tab displays an alert. The alert states that the operation may take some more time to complete and that you must check the status after some time. A delay in the application response does not indicate that the application or its dependent component has faulted. Parameters such as workload, system performance, and network bandwidth may affect the application response. VCS continues to wait for the application response even after the timeout interval elapses.
If the application fails to start or stop, VCS takes the necessary action depending on the other configured remedial actions.
: This setting defines the number of times that VCS must try to restart a failed application. The value of App.RestartAttempts may vary between 0 and 5; the default value is 0. If an application fails to start within the specified number of attempts, VCS fails over the application to a configured failover system.
: This setting lets you specify an easy-to-use display name for a configured application. For example, Payroll Application. VCS may internally use a different application name to uniquely identify the application. However, the internal string, for example OraSG2, may not be intuitive to understand, or easy to recognize while navigating the application table.
Moreover, once configured, you cannot edit the application name, while you can modify the application display name as required. Note that the Symantec High Availability tab displays both the application display name and the application name.
