The cluster database management functions allow a cluster-aware application or resource DLL to access and update the cluster database. The cluster database management functions provide one way to access the cluster database. The other way is through the control code functions of the Cluster API:
It is recommended that applications and resource DLLs use the control code functions to access the cluster database. The cluster database management functions should only be used when the control code functions are inadequate. Never use the Win32 registry functions. Although the registry functions are similar to the cluster database management functions, they are unsupported in the cluster environment because they do not support data replication or logging.
The following functions can be used to manage the cluster database:
| Function | Description |
|---|---|
| ClusterRegCloseKey | Releases the handle of a cluster database key. |
| ClusterRegCreateKey | Creates a specified cluster database key. If the key already exists in the database, ClusterRegCreateKey opens it without making changes. |
| ClusterRegDeleteKey | Deletes a cluster database key. |
| ClusterRegDeleteValue | Removes a named value from a cluster database key. |
| ClusterRegEnumKey | Enumerates the subkeys of an open cluster database key. |
| ClusterRegEnumValue | Enumerates the values of an open cluster database key. |
| ClusterRegGetKeySecurity | Returns a copy of the security descriptor protecting the specified cluster database key. |
| ClusterRegOpenKey | Opens a cluster database key. |
| ClusterRegQueryInfoKey | Returns information about a cluster database key. |
| ClusterRegQueryValue | Returns the name, type, and data components associated with a value for an open cluster database key. |
| ClusterRegSetKeySecurity | Sets the security attributes for a cluster database key. |
| ClusterRegSetValue | Sets a value for a cluster database key. |
| GetClusterGroupKey | Opens the root of the cluster database subtree for a group. |
| GetClusterKey | Opens the root of the cluster database subtree for a cluster. |
| GetClusterNetInterfaceKey | Opens the root of the cluster database subtree for a network interface object. |
| GetClusterNetworkKey | Opens the root of the cluster database subtree for a network. |
| GetClusterNodeKey | Opens the root of the cluster database subtree for a node. |
| GetClusterResourceTypeKey | Opens the root of the cluster database subtree for a resource type. |
