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.

    2. The default user for running the basic app is the user that runs the MCCS process.
      If the process needs to run for another user other than the default user, then you must designate an execution account as follows.

The deleted resource will immediately disappear from the management web console.


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, if all the processes registered in the list are running, it is success.
If not, it is failures. When you register both the process list and the script, both the conditions should be met to be success.
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  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.
