Syntax
<Result> = HClusterDeleteNode(<Coordinator> , <Password> , <Node>)
<Result>: Boolean - True if the addition was successful,
- False otherwise. To get more details on the error, use ErrorInfo.
<Coordinator>: Character string DNS name of computer where the cluster coordinator is installed. <Password>: Character string Password used to connect to the coordinator. This password was given when installing the cluster. <Node>: Character string DNS name of the node to disable. Remarks Operating mode of the nodes in a cluster The address of the cluster coordinator is written into the configuration file of each one of the nodes when they are installed. Therefore, when starting the HFSQL Server service, the node is automatically connected to the cluster. When a node is enabled by HClusterAddNode, this node synchronizes its databases with the ones of the other nodes and it processes the connection requests from the clients. When a node is disabled by HClusterDeleteNode, this node stops synchronizing its databases and it does no longer accept any connection from the client applications.
