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 | Note |
|---|---|---|---|
Online All the processes registered in MonitorProcesses are running and MonitorProgram returns '0'. | Offline | Runs the script registered in the StopProgram attributes. | |
| Monitoring | Runs the scripts registered in the MonitorProgram attributes. | ||
Offline If any one of the processes registered in MonitorProcesses is terminated or the monitoring program returns a non-zero value, it is deemed as offline. | Online | Runs the script registered in the StartProgram attribute. | |
| Monitoring | Refer to the description of monitoring as above. | ||
Trouble When the online resource is switched to offline without using the agent termination command, it is defined as the trouble state. | Online | Refer to the above online command. | |
| Offline | Runs the script registered in the StopProgram attributes. |
