Hello, 
&nbsp;  
&nbsp; Exactly, which method would I need to use to enable or disable a server from load balancing? 
&nbsp;  
&nbsp; thanks

Look at the LocalLB::PoolMember::set_session_enabled_state() method.  
    
   struct IPPortDefinition {  
    String address;  
    Long port;  
  };  
    
  enum EnabledState {  
    STATE_DISABLED = 0, // The object is disabled.    
    STATE_ENABLED = 1   // The object is enabled.    
  };  
    
  struct MemberSessionState {  
    IPPortDefinition member  
    EnabledState session_state  
  };  
    
  void LocalLB::PoolMember::set_session_enabled_state(  
    in String[] pool_names,  
    in MemberSessionState[][] session_states  
  );  
    
  You call this with an array of pools that you want to manipulate in the pool_names variable and then pass the members for each of the pools you want to change in the session_states variable.  
    
  If you want to disable all access to a given Node, you can can also set the session state at a global address level using the LocalLB::NodeAddress::set_session_enable_state() method  
    
  void LocalLB::NodeAddress::set_session_enabled_state(  
    in String[] node_addresses,  
    in EnabledState[] states  
  );

I've been using LocalLBNodeAddress.set_session_enabled_state and it doesn't appear to do anything on the node. I inserted some debugging into my code to try to break down what it's doing: 
&nbsp;  
&nbsp; lbNode.set_session_enabled_state( new string[] { "1.2.3.4" }, new LocalLB9.NodeAddress.CommonEnabledState[] { STATE_ENABLED }) ) 
&nbsp;  
&nbsp; After it's done, the 1.2.3.4 node's enabled_status continues to be ENABLED_STATUS_DISABLED.

NodeAddress::set_session_enabled_state will set the configuration setting that allows new sessions to be established to the node addresses. 
&nbsp;  
&nbsp; NodeAddress::get_session_enabled_state will retrieve the configuration setting that got set above. 
&nbsp;  
&nbsp; However, to find out the effective session status of the node address after calling set_session_enabled_state, you'll have to call NodeAddress::get_session_status. 
&nbsp;  
&nbsp; The same goes for LocalLB's Pool and PoolMember interfaces.

How would I completely disable a node such that it does not take anymore connections? 
&nbsp;  
&nbsp; thanks

Also, what are the pros\cons of using LocalLB::NodeAddress::set_session_enable_state() over LocalLB::PoolMember::set_session_enabled_state() to enable\disable DIPs?
