set_availability

You've found a difference in the enums for AvailabilityState and EnabledState.

 

 

For the set_state() method is defined as the following:

 

 

enum EnabledState {     
        STATE_DISABLED = 0, // The object is disabled.        
        STATE_ENABLED = 1 // The object is enabled.        
    };     
        
    void ITCMLocalLB::Node::set_state(     
        in IPPortDefinition[] node_defs,     
        in EnabledState state     
    );

 

 

And for set_availability():

 

 

enum AvailabilityState {     
        AVAILABILITY_UNCHECKED = 0, // The node has not been checked for availability.        
        AVAILABILITY_DOWN = 1, // The node is not available.        
        AVAILABILITY_UP = 2, // The node is available.        
        AVAILABILITY_CHECKING = 3, // The node is currently being checked for  availability.        
        AVAILABILITY_FORCED_DOWN = 4, // The node has been forced down manually.        
        AVAILABILITY_ADDR_DOWN = 5, // The node address for a node server is down.        
        AVAILABILITY_UNKNOWN = 6, // An unknown, undecipherable state has been received for the node. 
        AVAILABILITY_MAINT = 7, // Maintenance mode.        
        AVAILABILITY_ENABLED = 8, // The node is enabled.        
        AVAILABILITY_DISABLED = 9, // The node is disabled.        
        AVAILABILITY_ADDR_DISABLED = 10, // The node address is disabled.        
        AVAILABILITY_PORT_DISABLED = 11 // The node service is disabled.        
    };     
        
    // Sets the availability state for the specified nodes.   
    //Only AVAILABILITY_UP and AVAILABILITY_DOWN should be set.     
    void ITCMLocalLB::Node::set_availability(     
        in IPPortDefinition[] node_defs,     
        in AvailabilityState state     
    ); 

 

 

You'll notice that the enums are different. For set_state(), the EnabledState has valid values of 0 (STATE_DISABLED) or 1 (STATE_ENABLED), while the set_availability() method, as stated in the documentation, only allows the values of 1 (AVAILABILITY_DOWN) or 2 (AVAILABILITY_UP).

 

 

You'll need to change your code to the following:

 

 

    
    If intSwitch = 1 Then     
        state = 2 ' AVAILABILITY_UP     
      Else     
        state = 1 ' AVAILABILITY_DOWN     
      End If     
      objNode.set_availability(node_defs, state) 

 

 

This was introduced in version 1.0 of the SDK and we haven't been able to change the order of the enum values due to avoiding breaking existing applications.

 

 

The error you are receiving of InvalidArgument is actually correct for when you are passing in a value of 0 because that is an invalid argument per the documentation.
