The application resource is the resource where MCCS can start or terminate the program and monitor the status.
It is similar to the process resource. But, it can achieve more complex process and combination by using scripts beside general process execution. In addition, the application resource can set the execution path for starting, terminating or monitoring.
We execute the programs by using the batch scripts because we can handle everything even if the name of start program is different from the name of running process as in the case of service applications.
Sometimes, in the list of running processes, we need to monitor (response test) whether the process is providing proper service as well as monitoring the existence of process (existence test). To process such tasks flexibly, we can use the batch scripts.
In the application resource, you can enter the scripts. Just like the process resource, the applications can basically run on the root account, but by using User attributes, you can run it on a specific user account.

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. |
Attribute

MonitorProgram | Enter the path for the program or batch script used to monitor status | FILE | O | ||
StartProgram | Enter the path for the batch script or program to run when starting the resource. | FILE | O | ||
StartupDirectory | It is the working directory where the program starts. If there is no input, it means $MCCS_HOME. | DIRECTORY | (.) | O | |
StopProgram | It is the path for the batch script or program to run when terminating the resource. | FILE | O | ||
