An application is similar to Process resource, but it is more flexible and can be managed by batch script which contains multiple processes.
The reason why program is executed using batch script is because it will make it possible managed by MCCS even when the name of starting program and running program is not the same. Besides this, it not only monitors the existence of process but also monitors the response of process with this.
For these reasons, batch script will provide more detail monitoring and flexibility and an application agent manages this.
Same as process, application is basically executed with the system account, but is can be executed with particular user by using attributes of User, Password, Domain.

Status

The following table explains the status switching of the MCCS resource caused by a user's command and the status.
The command assumes that it is generated by a user

Application agent: It manages general application items.
It provides a more complex, wider expandability than processes to manage applications and services.

Status	Agent command	Description
Online MonitorProcesses에 등록된 모든 프로세스들이 실행 중이고 MonitorProgram이 '0'을 반환하는 상태입니다.	Offline	StopProgram 속성에 등록된 스크립트를 실행합니다.
	Monitoring	MonitorProgram 속성에 등록된 스크립트를 실행합니다. 스크립트로 감시할 경우에는 종료값이 0 일 경우 성공, 그 외의 경우에는 실패를 의미합니다. MonitorProcesses 속성에 등록된 프로세스 목록으로 감시할 경우 리스트에 등록한 모든 프로세스가 구동 중일 경우 성공, 그렇지 않으면 실패를 의미합니다. 프로세스 목록과 스크립트를 모두 등록할 경우에는 2 가지 조건을 모두 만족해야만 성공을 의미합니다. 프로세스 목록이 없거나 스크립트가 성공이 아니라면 실패로 간주하게 됩니다.
Offline MonitorProcesses에 등록된 프로세스 중에서 하나라도 종료되었거나 감시 프로그램이 '0'이 아닌 값을 반환할 때는 오프라인 상태로 판단합니다.	Online	StartProgram 속성에 등록된 스크립트를 실행합니다. StartProgram 속성은 배치 스크립트를 사용하여 기본 응용 리소스보다 유연하게 프로그램을 실행할 수 있습니다. 잘못된 경로를 입력한 경우에는 MCCS가 에러 로그를 출력하고 리소스를 사용할 수 없게 합니다.
	Monitoring	위에 모니터링 명령 참조
Trouble 리소스가 온라인 상태에서 에이전트의 종료 명령을 거치지 않고 오프라인 상태로 변경되었을 경우에 장애 상태로 판단합니다.	Online	위에 온라인 명령 참조
	Offline	StopProgram 속성에 등록된 스크립트를 실행합니다.
