After you have done the preparation work, you can activate EE to receive benefits provided by EE.

Perform the following steps to start EE:

1. Enable z/OS® Communications Server to accept or initiate EE connections by activating the EE XCA major node:
   • The first line activated in the EE XCA major node establishes a VTAM® connection to the TCP/IP stack supporting Enterprise Extender. When this communication is established, the following messages appear on the console:

     EZZ4313I INITIALIZATION COMPLETE FOR DEVICE IUTSAMEH       
     EZZ4324I CONNECTION TO 9.67.1.3 ACTIVE FOR DEVICE IUTSAMEH

   • For the first line activation associated with each unique static VIPA address (IPADDR or HOSTNAME), VTAM registers this VIPA address with the TCP/IP stack for EE communications. Any other line you activate from a group results in a new message that indicates VIPA activation. The following message appears on the console:

     EZZ4324I CONNECTION TO 9.67.1.5 ACTIVE FOR DEVICE IUTSAMEH
     EZZ4324I CONNECTION TO 9.67.1.7 ACTIVE FOR DEVICE IUTSAMEH

     Each message signifies that EE is registering the new static VIPA address with the TCP/IP stack and that the VIPA is ready to use.

2. Establish outbound EE connections by configuring a predefined EE network. Perform the following actions:
   • Activate the EE switched major node.
   • Dial the associated switched PU.

        V NET,DIAL,ID=SWIP2A1       
                                         
     	   IST097I VARY ACCEPTED                                           
     	   IST590I CONNECTOUT ESTABLISHED FOR PU SWIP2A1 ON LINE LNIP1     
     	   IST1086I APPN CONNECTION FOR NETA.SSCP2A IS ACTIVE - TGN = 21   
     	   IST241I VARY DIAL COMMAND COMPLETE FOR SWIP2A1                  
     	   IST1488I ACTIVATION OF RTP CNR00002 AS PASSIVE TO NETA.SSCP2A   
     	   IST1488I ACTIVATION OF RTP CNR00001 AS ACTIVE TO NETA.SSCP2A    
     	   IST1096I CP-CP SESSIONS WITH NETA.SSCP2A ACTIVATED

     If the partner is ready to accept connections, connections will be established. To establish connections using EE connection network, see Configuring the EE connection network.

3. Accept inbound EE connections by activating a switched PU to receive inbound connections. Use one of the following methods to identify the switched PU that will receive the EE connection.
   • Activate a switched PU to receive the incoming connection.
   • Specify DYNPU=YES on a GROUP within the XCA major node to indicate that a dynamic PU should be created when inbound connections arrive. Optionally, specify a model to be used for creation of dynamic physical units for incoming calls by activating a model major node containing a PU statement with DYNTYPE=EE specified.
