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.

Adding

Add the complex application resource to a group.

Adding in Group

  1. Select a group → right click → 'Add Resource'.

  2. Select 'Application' from Resource Type lists and click 'Next' button.

  3. 리소스 이름, 시작 프로그램, 종료 프로그램, 감시 프로그램 혹은 감시대상 프로세스 목록을 입력합니다Enter the name of resource and the program for start, termination and monitoring, or the process lists for monitoring target.
    In the start, terminate or monitoring program, click the Image Modified'File' button to select each script file
    or, click the Image Modified'Edit' button to create a script file.

    Info
    1. 감시 프로그램과 감시대상 프로세스 목록이 모두 입력이 될 경우 감시 프로그램의 성공여부와 감시대상 프로세스 목록의 여부까지 모두 확인합니다.
    2. 기본응용 프로그램을 실행 할 사용자의 기본값은 MCCS 프로세스를 실행하는 사용자입니다.
      만약 기본값이 아닌 다른 사용자로 프로세스를 실행해야 한다면 다음과 같이 실행계정을 지정해 주시기 바랍니다If all of the monitoring programs and the process lists for monitoring target are entered, check whether the monitoring program is successful or whether there are process lists for monitoring target.
    3. 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.

  4. Click 'Finish' to see that the complex application resource is created as follows.
    You can immediately check the result in the management web console. 



Deleting

Select resource type → right click → delete resource.
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.

...

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.
