    摘要: A method and apparatus for sharing state information among a plurality of servers is provided. A first server receives a request to perform a file operation, such as a NFS file system operation. Thereafter, the first server updates state information to reflect a change in state associated with processing the request. The first server then causes state update information, which identifies the change in state that was made at the first server, to be propagated to a second server. The second server updates state information, stored at the second server, to reflect the change in state associated with processing the request at the first server. Advantageously, a client may send a series of stateful file operations to either the first server or the second server, even if processing any one of the stateful file operation requests requires knowledge of the state of processing prior requests in the series of requests.

    摘要: A method and apparatus for performing file system operations involving a link is provided. A request to perform a file system operation involving a link is received from a client at a database server. The link may establish a relationship a source resource has to a target resource. The source resource and the target resource may be stored within a repository implemented by a storage medium, such as a database. The database server may perform the file system operation by storing, in the database, one or more link records that identifies the link between the first resource and the second resource. File system operations, such as a NFS file system operation, which involve links may be performed at a database management system.

    摘要: A method and apparatus for performing an action in response to a file system event is provided. According to one aspect, sets of “event listeners” are associated with a file hierarchy and/or the nodes thereof. Each event listener contains a set of “event handlers.” Each event handler corresponds to a separate type of event that may occur relative to the file hierarchy's nodes. When an event is going to occur relative to the hierarchy or a node thereof, all event listeners that are associated with that hierarchy/node are inspected to determine whether those event listeners contain any event handlers that correspond to the event's type. Those event handlers that correspond to the event's type are placed in an ordered list of event handlers to be invoked. As the event handlers in the list are invoked, programmatic mechanisms that correspond to those event handlers are executed to perform customized user-specified actions.

    摘要: Techniques are provided for accessing and storing files within a virtual folder. A virtual folder is a folder that is logically a part of a hierarchical folder structure of a file system repository, but the contents of the virtual folder are not physically stored in the file system repository. A client may issue, to an access mechanism, a request to perform a file operation on a file in a virtual folder. The access mechanism, which may be a database server or a component therein, may perform the file operation on the file in the virtual folder as if the file was stored in a particular folder within the hierarchical folder structure implemented by the file system repository. Advantageously, files may be physically stored outside of the file system repository, but still be a part of the hierarchical folder structure implemented by the file system repository.

    摘要: A mechanism is used to improve the efficiency of performing resource-to-path resolution. A hierarchical link structure contains entries and/or records (“link entries”) that each defines a parent-child link within an information hierarchy. A certain linking entry may have data that refers to another link entry representing a link to the parent—a link in which the parent is a child. This data allows resource-to-path resolutions to be performed more efficiently.
