Method to disable/enable a server?

Hi,

 

 

When looking at the LocalLBNode perl example, I was wondering if there is a method to disable/enable a server, or do you have to loop through all the nodes on a server?

 

 

Thanks

    Yes, there are methods to enable/disable individual pool members and node addresses. For example, in v9.x:

     

     

    - LocalLB::PoolMember/NodeAddress::set_session_enabled_state - if set to TRUE, will disallow new sessions from establishing, while still allowing existing sessions to go through, essentially used to bleed off the existing connections.

     

     

    - LocalLB::PoolMember/NodeAddress::set_monitor_state - if set to TRUE, will bring the pool member or node address down immediately.

     

     

    Please refer to the SDK for the signatures and descriptions of these methods.

    By "Server" do you mean "Virtual Server" or a single Node Address. There are several ways to disable services.

    1. Disable service on a specific node:port (Node Server). 

    void ITCMLocalLB::Node::set_state( 
     in IPPortDefinition[] node_defs, 
     in EnabledState state 
 );

    2. Disable service on all services for a given node (Node Address). 

    void ITCMLocalLB::Node::set_node_address_states( 
     in String[] node_ips, 
     in EnabledState[] states 
 );

    3. Disable an entire Virtual Address 

    void ITCMLocalLB::VirtualServer::set_state( 
     in IPPortDefinition[] virtual_servers, 
     in EnabledState state 
 );
