MCCS에서 리소스를 다루기 위한 명령은 관리 콘솔에서 왼쪽 뷰의 리소스를 선택한 후에 마우스의 오른쪽 클릭으로 생성된 팝업 화면에서 선택할 수 있습니다.
또 다른 곳은 그룹을 선택한 후에 '리소스 의존성' 탭에서 해당 리소스에 마우스의 오른쪽을 클릭하면 리소스와 같은 팝업 화면을 생성시킬 수 있습니다.
이 외에도 콘솔의 메뉴 항목이나 툴 바 메뉴에서 명령을 내릴 수 있으며 CLI 로도 가능합니다If you want to use the resource handling commands in MCCS, go to the management console and select the resource in the left view and right click with your mouse button to launch the pop up window.
Alternatively, select group and right click with your mouse button on the resource in the 'Resource Dependency' tab to launch the same pop up as resource.
Also, you can use the commands in the console menu or tool bar. CLI can be used as well.
Enable Resource
This can be checked by checking of there is a enabled check mark in front of the command. This can also be checked by checking on the Enabled value in the Resource Attribute. If the resource is disabled, resource state cannot be monitored.
If the attribute value is incorrect, this will be failed. For example, when type a wrong path name in the process of application, monitoring whether it is online or offline is impossible. Therefore, whenever this is failed, attribute value should be checked first.
