A system and method using inheritance for the configuration, management, and / or monitoring of computer applications and devices via a computer network are disclosed. The method generally comprises determining a hierarchical tree structure based upon locations of devices in a network topology, each device being a node in the hierarchical tree structure, determining policies for each node in the hierarchical tree structure to be enforced by an agent corresponding to each node, the agent being in communication with the device and the resources corresponding to the device, and communicating the policy to the corresponding agent, wherein the policies corresponding to the resources of each device are selectively inherited along the hierarchical tree structure of the network directory.

An intelligent network client has the capability of accessing a first network server in accordance with a first high-level file access protocol, and responding to a redirection reply from the first network server by accessing a second network server in accordance with a second high-level file access protocol. For example, the intelligent network client can be redirected from a CIFS / DFS server to a NFS server, and from an NFSv4 server to a CIFS server. Once redirected, the intelligent network client performs a directory mounting operation so that a subsequent client access to the same directory goes directly to the second network server. For example, the first network server is a namespace server for translating pathnames in a client-server network namespace into pathnames in a NAS network namespace, and the second network server is a file server in the NAS network namespace.

The improved DBMS system of the present invention can be used to realize an improved Data Warehouse for supporting on-line analytical processing (OLAP) operations or to realize an improved informational database system, operational database system, or the like.

A system and method for updating a replicated destination file system snapshot with changes in a source file system snapshot, facilitates construction of a new directory tree on the destination from source update information using a temporary or “purgatory” directory that allows any modified and deleted files on the destination active file system to be associated with (e.g. moved to) the purgatory directory if and until they are reused. In addition, an inode map is established on the destination that maps source inode numbers to destination inode numbers so as to facilitate building of the destination tree using inode / generation number tuples. The inode map allows resynchronization of the source file system to the destination. The inode map also allows association of two or more destination snapshots to each other based upon their respective maps with the source.

An efficient write-watch mechanism and process. A bitmap is associated with the virtual address descriptor (VAD) for a process, one bit for each virtual page address allocated to a process having write-watch enabled. As part of the write-watch mechanism, if a virtual address is trimmed to disk and that virtual address page is marked as modified, then the corresponding bit in the VAD is set for that virtual address page. In response to an API call (e.g., from a garbage collection mechanism) seeking to know which virtual addresses in a process have been modified since last checked, the memory manager walks the bitmap in the relevant VAD for the specified virtual address range for the requested process. If a bit is set, then the page corresponding to that bit is known to have been modified since last asked. If specified by the API, the bit is cleared in the VAD bitmap so that it will reflect the state since this time of asking. If the bit is not set, to determine if the page was modified, the page table entry (PTE) is checked for that page, and if the PTE indicates the page was modified, the page is known to be modified, otherwise that page is known to be unmodified since the last call. One enhancement uses page directory tables to locate a series of trimmed pages, sometimes avoiding the need to access the PTE.

A switched file system, also termed a file switch, is logically positioned between client computers and file servers in a computer network. The file switch distributes user files among multiple file servers using aggregated file, transaction and directory mechanisms. The file switch supports caching of a particular aggregated data file either locally in a client computer or in the file switch in accordance with the exclusivity level of an opportunistic lock granted to the entity that requested caching. The opportunistic lock can be obtained either on the individual data files stored in the file servers or on the metadata files that contain the location of each individual data files in the file servers. The opportunistic lock can be broken if another client tries to access the aggregated data file. Opportunistic locks allows client-side caching while preserving data integrity and consistency, hence the performance of the switched file system is increased.

A method for searching a document directory hierarchy which partitions a user-initiated search. The document directory hierarchy comprises a plurality of document directories stored in a tree data structure. Each of the plurality of document directories corresponds to a category within a class hierarchy and stores at least one document. A user query comprising one or more search terms is accepted from an input device. If the user query includes a user-selected category, a directed search is performed. However, if the user query does not include a user-selected category, an undirected search is performed. The directed search confines the search to one of the plurality of document directories corresponding to the user-selected category, and returns relevant documents within the user-selected category. The undirected search is performed within each of the plurality of document directories within the document directory hierarchy, and returns relevant categories corresponding to document directories within the document directory hierarchy.

Preferably for use in a directory enquires system, the invention provides a method and system for processing user records to determine common entries therebetween. When two user records are determined to store common information then link data is generated (18) and stored in each user record (22) indicating a link between the two records. This link information is then used in subsequent searching (20) of the user records to determine the most likely result from a list of possible results obtained from a search of the user records. In a directory enquiries system (14) the user records contain user ID and telephone number details as well as address book data of each user's friends, family, or other acquaintances. The address book data is used to determine whether a link between user records should be formed.

A namespace server translates client requests for access to files referenced by pathnames in a client-server namespace into requests for access to files referenced by pathnames in a NAS network namespace. The namespace server also translates between different file access protocols. If a client supports redirection and is requesting access to a file in a file server that supports the client's redirection, then the namespace server may redirect the client to the NAS network pathname of the file. Otherwise, the namespace server forwards a translated client request to the file server, and returns a reply from the file server to the client. A file server may redirect a redirection-capable client's access back to the namespace server for access to a share, directory, or file that is offline for migration, or for a deletion or name change that would require a change in translation information in the namespace server.

A system and related techniques provide a seamless, peer-to-peer file synchronization capability for sharing files, folders, directories or other stored content between machines. According to embodiments of the invention in one regard, a sync engine or other file management logic may be integrated into the operating system or other resources of a user's desktop, laptop, network-enabled cellular device or other computer, client, machine or other hardware. The sync engine may accept user designations of files, folders, directories or other contents which they wish to share, sync or roam between two or more selected machines, on an automatically consistent basis. The sync engine or other control logic may maintain a file system log to record the state of files which have been designated for sharing, to indicate for example whether a transmission of the file has been made, to which target machine or machines it has been transmitted, and other variables regarding the state of file or other content. According to embodiments of the invention in one regard, the sync engine may apply version management logic when files located on a target or destination machine, may, for example, reflect newer or more complete content than the file which is designated for roaming to that machine, or other under conditions. A user may therefore readily and with a comparative minimum of configuration effort select and effectuate the sharing of a set of frequently used or otherwise desired files to an arbitrary set of machines which they own or use, without a need to invoke a remote server or other control or storage to back up and synchronize that content.

A harvester is disclosed for harvesting metadata of managed objects (files and directories) across file systems which are generally not interoperable in an enterprise environment. Harvested metadata may include 1) file system attributes such as size, owner, recency; 2) content-specific attributes such as the presence or absence of various keywords (or combinations of keywords) within documents as well as concepts comprised of natural language entities; 3) synthetic attributes such as mathematical checksums or hashes of file contents; and 4) high-level semantic attributes that serve to classify and categorize files and documents. The classification itself can trigger an action in compliance with a policy rule. Harvested metadata are stored in a metadata repository to facilitate the automated or semi-automated application of policies.

An interface for enabling different contact information for a plurality of different contacts to be aggregated from numerous data stores into a single contact management system includes a window frame for displaying the contact information in a variety of rich views that graphically illustrate patterns existent within the contact information. Some of the available views include hierarchical, organizational, chronological, social, geographical and operational views of the contact information. The interface also enables a user to search through the aggregate contact information by search term and by filter. The interface also includes another window frame for displaying exploded, detailed, or additional information about selected directories and contacts.

The invention provides a method and system for correct interoperation of multiple diverse file server or file locking protocols, using a uniform multi-protocol lock management system. A file server determines, before allowing any client device to access data or to obtain a lock, whether that would be inconsistent with existing locks, regardless of originating client device or originating protocol for those existing locks. A first protocol enforces mandatory file-open and file-locking together with an opportunistic file-locking technique, while a second protocol lacks file-open semantics and provides only for advisory byte-range and file locking. Enforcing file-locking protects file data against corruption by NFS client devices. A CIFS client device, upon opening a file, can obtain an "oplock" (an opportunistic lock). When a client device issues a non-CIFS protocol request for the oplocked file, the file server sends an oplock-break message to the CIFS client device, giving the CIFS client device the opportunity to flush any cached write operations and possibly close the file. Allowing NFS and NLM requests to break oplocks ensures that file data remains available to NFS client devices simultaneously with protecting integrity of that file data. A CIFS client device can obtain a "change-monitoring" lock for a directory in the file system, so as to be notified by the file server whenever there is a change to that directory. The file server notes changes to the directory by both CIFS and non-CIFS client devices, and notifies those CIFS client devices with "change-monitoring" locks of those changes.

A switched file system, also termed a file switch, is logically positioned between client computers and file servers in a computer network. The file switch distributes user files among multiple file servers using aggregated file, transaction and directory mechanisms. The file switch ensures consistent and atomic behavior of the switched file system by aggregating in a deterministic way the transactions initiated by the client of multiple independent file switches so that only one of the multiple concurrent transactions attempted on the same aggregated data file may succeed, or so that the transactions are serialized so as to be performed as a sequence of atomic operations. In addition, the integrity of the aggregated data file is safeguarded by issuing locking requests on behalf of certain client applications that do not observe locking mechanism consistently.

A Web Interface and Method for Accessing Directory Information is disclosed. A Web Interface for Accessing Directory Information comprises a request mapper that links directory data to a template file in response to a directory request, and a friendly name mapper that correlates an abbreviated name to a non-abbreviated name. The abbreviated name refers to at least one entry of said directory data. A method for accessing directory information in accordance with the invention comprises the following steps: (1) receiving a request for directory data; (2) determining whether the request is a distinguished name request, wherein the distinguished name request is a request for a distinguished name; (3) in response to a determination that the request is not a distinguished name request, retrieving a directory resource corresponding to the request; (4) in response to a determination that the request is a distinguished name request, determining whether the distinguished name is mapped; (5) in response to a determination that the distinguished name is not mapped, retrieving an object class of the distinguished name and finding a template using the object class; and (6) in response to a determination that the distinguished name is mapped, finding a template using the distinguished name.

A method and system that reduces the length of time required to complete antivirus scans. An enhanced journal file system (JFS) includes an antivirus utility function, which utilizes a low level log of the JFS to store a history of transactions that occur since a previous scan operation. The log is immune from normal purge operations by the JFS and cannot be circumvented without driver level access. Thus, a virus that changes the timestamp on the file or otherwise attempts to hide its viral activity does not affect the log. When the antivirus scanning utility initiates an antivirus scan of the system, the antivirus scanning utility obtains the history since the last scan from the persistent log. The antivirus scanning utility “replays” the log and carries out the antivirus scan on all files, directories, etc. associated with any transactions that occurred since the last scan.

An electronic data system comprises memory storage having stored data, file system software, and a transaction file. The transaction file is maintained by the file system software, and includes a plurality of transaction records corresponding to transactions that have been or are to be executed on one or more files and / or the or more directories of the file system. The file system software operates to organize and maintain the stored data in the files and directories and also to coalesce multiple transaction records meeting one or more criteria into fewer coalesced transaction records. The physical memory space required by the transaction file is reduced by the transaction record coalescing. The coalesced transaction records may be constructed so that they represent a logical result of applying each transaction record of a transaction record set in chronological order. Once the coalesced transaction records have been committed in the file system, the physical memory used by the original transaction records in the set may be reclaimed for further use (e.g., to store further transaction records) or may be otherwise removed from further use (e.g., when the physical memory is located in a block of memory in a flash-like memory device that has reached its maximum number of write and / or erase cycles).

A method and system is disclosed for providing storage services to Virtual Machines (VMs) and the Hypervisor Platforms that host them. NAS referrals are used to control selection of NAS proxy servers that are optimized for the support of VMs and the Hypervisor Platforms accessing directories that are exclusively used in conjunction of a single VM. Referrals are dynamically controlled in a manner specific to the target environment to provide an optimal combination of local and network storage in support of VMs. A method of using named attributes allows referrals to subsets of a directory. The overhead of using a NAS proxy is tailored to the smallest set of accesses required to gain beneficial result from the use of local storage, and using direct access to shared network storage when local storage is not allocated. Most of the new suggested techniques are transparent to the existing NAS clients; some techniques may require modification of the NAS client software.

Image data gathered by a scanner portion is stored into an image file, and stored into a hard disc. A client terminal requests a copy server to send management information of the image files in the hard disc. A control portion that receives the file management information request reads out file management information on the image files in a requested directory, from the hard disc, and sends it to a client terminal. An operator selects an image file on the basis of the management information, and the copy server is requested to down load a corresponding image file.

A system and method of operating a filesystem for managing filesystem objects is disclosed. The filesystem objects are characterized by metadata parameters included in a global directory object arranged in a plurality of global directory object (GDO) pages. Responsive to receiving a request for creating a new filesystem object, a parent key is obtained. The parent key is indicative of an identifier of a direct parent directory requested for hosting the new filesystem object. A target page that corresponds to the parent key is located within the plurality of GDO pages. The target page further includes a direct parent directory metadata record associated with the direct parent key and includes metadata parameters related to the direct parent directory. An object key is created as corresponding to the same target page, thereby enabling accommodation of an object metadata record, related to the new filesystem object, on the target page.

A system and method for automatically saving the contents of volatile memory in a data processing device on power failure. A secondary power supply is provided, which upon failure of the primary power supply supplies power long enough for all modified information stored in volatile memory to be written to a non-volatile memory device such as NAND flash in an AutoSave procedure. In the preferred embodiment modified sectors in volatile memory are flagged, and only modified sectors with a directory list are written to non-volatile memory during the AutoSave procedure.

In a machine translation environment, a context-specific domain directory must sometimes be selected to provide a proper translation in context. A database for trigger patterns associated with specific domains is prepared. When a resource is to be translated, appearances of the pattern within the resource are detected. If appearance frequency for at least one domain exceeds a threshold value, the appearance frequency for that domain is compared to the appearance frequency for other domains. If the appearance frequency for the one domain is found to be significantly higher, the dictionary for that domain is selected for the translation.
