are responsible for providing access to the underlying data presented by the server. The data may be stored locally in an embedded database, remotely in an external system, or generated on the fly (for example, calculated from other information that is available). ds-cfg-local-backend ds-cfg-backend Specifies the fully-qualified name of the Java class that provides the backend implementation. org.opends.server.api.LocalBackend ds-cfg-java-class Specifies the behavior that the backend should use when processing write operations. Allows write operations to be performed in that backend (if the requested operation is valid, the user has permission to perform the operation, the backend supports that type of write operation, and the global writability-mode property is also enabled). Causes all write attempts to fail. Causes external write attempts to fail but allows writes by replication and internal operations. ds-cfg-writability-mode
