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.

StatusAgent commandDescriptionNote

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.
When the scripts are used for monitoring, the final value of 0 means success and other value means failures.
When you use the list of processes registered in the MonitorProcesses attributes for monitoring, then if all the processes registered in the list are running, it is success. If not, it is failures.
When both the process list and script are registered, meeting both the conditions means success, and if there is no process list or the script is not successful, it is regarded as a failure.

 

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.
StartProgram attributes allow you to use the batch scripts to run the program in a more flexible way than the process resource.
If the wrong path is entered, MCCS will display an error log and the resource cannot be used.

 
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.

 
OfflineRuns the script registered in the StopProgram attributes.
