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.

- When add a resource from a group name, select a group → right click → "Add Resource". Or select "Edit(E)" from the main menu bar → select "Add Resource". Or select "Add Resource" icon from the tool bar.
- Select "Application" from Resource Type lists and click "Next" button. When add a resource from the Application resource type name, this step will be skipped.
- Enter the resource name and the pre-scripted file name for start, stop and monitoring with full path or click theÂ
 to browse the file, or click the 
 to create user defined script file. Enter the process name where listed in task manager of Windows O.S for monitoring target into MonitorProcesses box.
- You can enter the value into MonitorProgram or MonitorProcess to monitor whether the application runs properly. You should enter the value in at least one of them.
- When all the value of MonitorProgram and MonitorProcesses are entered the process lists for monitoring target are entered, MCCS checks whether the monitoring program is properly work and whether processes which is monitoring target are exist.
- The default Execution Account of the process is Account running MCCS. If the resource runs specified account, you can select Specify Account and enter account informations such as domain, user account and password.

State
The following table explains the state of application resource.
Applications agent: Manages applications. It is more complex than single-process one, and provides wider extensibility so that it can manage applications and services and others.
| State | Agent command | Description | Note |
|---|---|---|---|
Online All the processes into MonitorProcesses are running properly and MonitorProgram returns '0'. | Offline | Runs a script registered on the StopProgram attribute. | |
| Monitoring | Runs a script registered for the MonitorProgram attribute. In the case of monitoring with a script, the "0" results indicates success and the others means failure. In the case of monitoring with a list of processes registered for the MonitorProcesses attribute, the situation that all the processes in the list are operating indicates success, otherwise, means failure. In the case that both a processes' list and a script have been registered, it indicates success if both of each success case are satisfied, the others means failure. It is considered as failure if any process included in a list does not appear or a script does not run well. | ||
Offline When one of the process into MonitorProcesses is at least offline or 'MonitorProgram' does not return in '0'. | Online | Runs a script registered on the StartProgram attribute. The StartProgram attribute helps with more flexible running of a program than single-process resource by using a batch script. It limits to use of a resource with outputting an error log from MCCS if inputting a wrong path. | |
| Monitoring | Refer to the Monitoring item above. | ||
Fault When an onlined application has not taken offline through offline command, it is defined as fault. | Online | Refer to the Online item above. | |
| Offline | Runs a script registered on the StopProgram attribute. |
Attribute
Show the specified attribute of application resource.
Attribute | Description | type | Default | Edit | Note |
Domain | It specifies domain of user account. | STRING | O | ||
MonitorProcesses | It is the list of the process to be monitored. | STRING | O | At least either MonitorProcesses or MonitorProgram should be input. It is available to input values of both attributes all; and it is essential to satisfy with both attributes in order to online. | |
MonitorProgram | It is program or script based file for monitoring an object. | FILE | O | ||
Password | It is the password defined by the user.  | PASSWORD | O | ||
StartProgram | It is a program to bring online the Application in each node. | FILE | O | ||
StartupDirectory | It is a work directory. it means %MCCS_HOME if it does not have a value. | DIRECTORY | (.) | O | |
StopProgram | It is a program to take offline the Application of each node. | FILE | O | ||
User | It is a user name which has received the permission to use the application. | STRING | System Account | O |
Specified attribute values are normally entered when add the resource, This value can be edited or viewed through 'Specified Attribute' table in the Resource Attributes tab on the detailed information panel.
MCCS has function to limit input values against user's input field, and it provides function detects automatically data which is input wrong by user's mistake.
