Clues
Writing resource DLL is only part of the application or service that can be perceived by the cluster. Clusters can perceive applications, especially databases, and may implement a Custom Resource DLL specific to the application to manage database resources. The same application can use other resource DLL (disk resources, IP addresses, and so on) to obtain high availability and other functions provided by cluster services. Applications can use cluster APIs and other cluster-related functions (such as cluster control code) to make themselves more aware of clusters. Finally, the cluster can perceive that the application should use the cluster management extension DLL to provide management functions, so that the application can be easily installed and configured in the cluster environment.
Using appropriate tools, such as Microsoft's Visual C ++ and platform SDK, to compile resource DLL is simple and straightforward. Based on the important suggestions in the guidance and documentation, applications, clusters, and resources can interact more efficiently, ensuring the high availability of cluster resources across all applications and systems.
