In the previous step, Unit Testing the Batch Application, you used the Bankdemo enterprise server. You are going to use it again for online testing. 
	 
 
  
 
	 As with JCL, execution of the jobs requires a previously configured 
		Micro Focus enterprise server. 
	 
 
	 Important: You need 
		
Enterprise Developer or 
		
Enterprise Developer for z Systems to execute the application as running applications is not supported in 
		
Enterprise Developer Connect. 
	 
 
 
	 Starting the Bankdemo enterprise server
 
		 
		If the enterprise server is not yet started, you need to start it as follows: 
		
 
		 
		  - Click the Server Explorer tab. 
			  If the tab is not visible, click 
				. Select 
				Micro Focus > Server Explorer and then click 
				OK. 
			  
-  In the Server Explorer window, right-click the Bankdemo server and then click 
			 Start. 
			 Wait until the server has started. In the list of servers in Server Explorer, BANKDEMO still has a red square next to it. This is a refresh delay. 
			  
- In Server Explorer window, right-click 
			  and click 
			 Refresh to confirm the server has started. 
		  
Executing the CICS application 
 
		 
		The CICS application requires that you use a 3270 terminal emulator. The installation of 
		  Enterprise Developer includes the 
		  Micro Focus Rumba emulator. Rumba is available as a standalone application, Rumba Desktop, and is also available as a TN3270 Mainframe Display embedded within the IDE. As part of this tutorial, you are going to use the embedded display to run the application. 
		
 
	 Configuring the TN3270 settings in the IDE
 
		 
		To check the IDE preferences and ensure that the embedded Rumba display is selected: 
		
 
		 
		  - In the IDE, click 
			 Window > Preferences. 
		  
- Expand 
			 Micro Focus > Enterprise Server, and click 
			 TN3270. 
		  
- Ensure that 
			 Enable display, 
			 Rumba (Embedded) and 
			 Connect automatically are all selected. 
		  
- Click 
			 OK. 
		  
Starting the 
		  Rumba Mainframe Display view
 
		 
		 
		  - Right-click the BANKDEMO server in Server Explorer, and click 
			 Show TN3270 Display. 
			 This opens the 
				Rumba Mainframe Display view and automatically establishes a 3270 terminal connection to the BANKDEMO server. You can see the starting page of the ES/MTO region BANKDEMO. 
			  
- You can drag the 
			 Rumba Mainframe Display view to reposition it. 
		  
Executing the Enterprise Server Demonstration
 
		 
		 
		  - Press 
			 Ctrl+Shift+Z to clear this window. 
		  
- Type in the transaction id 
			 BANK and press 
			 Enter to navigate to an application logon window. 
		  
- Type your logon details and press 
			 Enter. 
			 A suitable 
				User Id is 
				b0001. You can type anything as a 
				Password - the field must not be empty though. 
			    
 
- Type 
			 / against 
			 Display your account balances and press 
			 Enter to see the details for this customer. 
			   
   
 
- You can explore this application further if you wish or press 
			 F3 to terminate it. 
		  
If the Rumba Mainframe Display view disconnects from the server, you can connect again manually as follows: 
		
 
		 
		  - Click the 
			 New Rumba Mainframe Display button, 
			  , in the toolbar of the Rumba Mainframe Display view. , in the toolbar of the Rumba Mainframe Display view.
- Specify the host name and the TN3270 port number for the Bankdemo server as follows: 
			   
 
- Click 
			 Connect. 
			 This connects the display to the Bankdemo server and loads the start screen of the application. 
			  
- Follow the steps described earlier in this topic to execute the application in the Rumba Mainframe Display view. 
		  
Stopping the enterprise server
 
		 
		You can stop the Bankdemo server from within Server Explorer. You can leave it running though, if you wish to continue this tutorial. 
		
 
		Note: In production, enterprise servers are long-running processes that are usually run for many months without stopping and starting.
