Enterprise Server comes with a pre-configured enterprise server named ESDEMO. However, it is not configured for Mainframe Subsystem Support (MSS). Therefore, you must create a new enterprise server instance configured for MSS for the CICS application. 
	 
 
	  
		- Start Visual Studio. 
		
- Open Server Explorer. 
		  If it is hidden, choose 
			 View > (Other Windows >) Server Explorer. 
		   
-  Right-click 
		  Micro Focus Servers and choose 
		  Administration from the context menu. 
		   This opens the home page of Enterprise Server Administration. 
		   Alternatively, you can start Enterprise Server outside of the IDE in a browser. Enter the following URL in the address bar: 
			 http://localhost:86. 
		   
- On the Enterprise Server Administration home page, click 
		  Add. 
		
- In the 
		  Server Name field, type 
		  CICSEXT. 
		
- Make sure the 
		  Working Mode is set to 
		  32-bit. 
		
- Click 
		  Next. 
		
- In the 
		  Server Type group, click 
		  Micro Focus Enterprise Server with Mainframe Subsystem Support. 
		
- Click 
		  Next. 
		
- In the 
		  Startup Options group, set the 
		  Service Execution Processes to 
		  3. Because the service interface is a screen-based CICS service, at least 3 SEPs are required for the service to run smoothly. 
		
- In the 
		  Creation Options group, be sure that 
		  Create TN3270 listener is checked. 
		
- In the 
		  using port field to the right of the checkbox, type 
		  9004. 
		  Note: If port 9004 is already in use on your system, specify another free port instead. 
		   
 
- In the 
		  Description field, type a description of the new enterprise server, for example, 
		  CICS Screen Tutorial. 
		
- Click 
		  Add. 
		
This displays the Enterprise Server Administration Home page with your new CICSEXT server on the list of the available enterprise servers.
