Abstract: An apparatus and a method operating on data at a server node of a data grid system with distributed cache is described. Data is copied to a network cloud of storage services remotely coupled to a server node with an asynchronous input output interface. The asynchronous input output interface is configured to asynchronously communicate with the network cloud of storage services. Confirmation that the data has been copied on the network cloud of storage services is received at the server node.

Abstract: A storage system has a primary storage device for storing data from host devices, and first and second secondary storage devices. When either the primary storage device or the first secondary storage device is in the process of maintenance and a failure occurs in the other secondary storage device data received from the host device is not lost, and the processing continues from the relevant data. The host device processor makes the first and second secondary storage devices perform a resync processing with reference to a relevant trigger that the respective status of the primary device and the first secondary storage device are both changed to the Suspend status. Then an I/O control unit copies the differential data between the copy data of the first secondary volume and the second secondary volume and transfers the data from the first secondary storage devices to the second secondary storage device.

Abstract: A method and system for controlling an application server in order to provide application services to clients while maintaining synchronization between records of tables of a database server. An application server retrieves records of tables and stores them locally on the application server. When a client requests some fields of a record of a table, the application server generates a bookmark that uniquely identifies the record. The bookmark may contain a table identifier and a record identifier or a query identification and an identifier of a record within the query result. The bookmark is opaque to the client and only the application server need know how to interpret its contents. When the application server provides the requested fields of the record to the client, it also provides the record bookmark to the client. When the client wants to identify the record, it uses the bookmark provided by the application server.

Abstract: To ensure data consistency for a new data replica created for a computing system, the transmission and receipt of messages altering the data are monitored and replication of the data is permitted when all changes to the data that have been transmitted to the data have been received.

Abstract: A storage area network (SAN) license validator manages data collection policies (DCPs) in deployed SAN agents by identifying data collection policies corresponding to unlicensed features, and disabling the DCPs for the unlicensed features. Thus, the agents need not expend computational and memory resources to gather data for unlicensed features that will not be queried. Agents receive a set of data collection policies (DCPs) for licensed features for which the corresponding data will be gathered and reported to the MODB. DCPs for unlicensed features are disabled in the agents that would have executed them, either by removing or canceling from an active DCP list or by omitting the unlicensed DCPs from the startup sequence of the agent. In this manner, agents operate with only the DCPs for licensed products and corresponding features, and need not gather extraneous data.

Abstract: An exemplary system enabling credential roaming among a plurality of different computing devices may include an event handler to receive event notifications such as, e.g., a client logon. The event handler may invoke a management service in response to receiving an event notification.

Abstract: Changes such as write operations on a replication source comprising a hierarchically-indexed file system and associated data store are tracked and aggregated over a point-in-time image replication interval and communicated to a replication target. The replication target receives the changes, conducts operations to make the changes on a target volume or portion thereof, and conducts a point-in-time image replication operation to synchronize the replication target with the replication source. In the present invention the advantages of replication techniques developed for log-structured file systems are provided to systems with conventional hierarchical file systems. The invention also facilitates maintaining point-in-time retrievable images of a volume or portion thereof on a target volume while reducing the bandwidth and processing burden associated with replication.

Abstract: Systems and methodologies are provided that employ an allocation lock, which permits only a single transaction to acquire space on a particular page at any one time. The allocation lock of the present invention facilitates operations of concurrent transactions at a subpage level (e.g., a row level), and in conjunction with a heap manager can enforce a set of conditions such that prior to a commit stage of a transaction, a space availability for a particular page can be typically assured (e.g., that transactions operating on various copies of the page do not consume all of storage space on that page), and reorganization of data around the page is mitigated (e.g., that a transaction need not move data around the page for purpose of merging various copies.

Abstract: Systems and methods for synchronizing verification data in a distributed database including client and server databases.

Abstract: Systems and methods for managing the processing of the same pieces of information, e.g., messages, by multiple consumers, in a prescribed order, without causing the degradation of any consumer's performance because of other consumers' access to the same information. A single information queue contains pieces of information to be accessed by multiple consumers. Each piece of information is stored in the information queue along with an information identifier that uniquely identifies the piece of information. A separate table is used to keep track of and identify the pieces of information in the information queue that have been accessed by respective consumers. This separate table is decoupled from the information queue, and, thus, each consumer's access of a piece of queued information does not impact any other consumer's access of the same piece of information.

Abstract: When a storage device initiates a change in its file system, it locally stores it for future update of the file system. When the host device sends a command to the storage device, the storage device responds to it by commencing a synchronization process during which the two parties coordinate the update of the file system with the stored change. If there are no file system changes pending in the host device, the storage device gets permission from the host device to update the file system with the change and, then, the host device reads the updated file system from the storage device. If there are file system changes pending in the host device, the host device updates a representation of the file system residing in the host device, causes the storage device to make the same changes, and then the storage device initiated change, in the file system. Lastly, the host device receives information from the storage device regarding the changes initiated by the storage device.

The request routing module is capable of providing optimal routing based on the network resources.

Abstract: A large message can be stored by separating the message into an envelope portion containing information such as headers, protocols, and addresses, and a payload portion containing items such as file attachments. The envelope portion can be stored in local storage, while the payload can be stored to a persistent store. The message can be processed incrementally, such that the entire message is never in system memory. Once the envelope portion is processed, the payload portion can be read in increments without being processed, and those increments written directly to the persistent store. Alternatively, the payload can be streamed to the persistent store. A pointer in the envelope can then be used to locate and retrieve attachments from persistent storage. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.

Abstract: Techniques are described for replicating data from one to one or more heterogeneous data processing or communication devices for the purpose of remote backup, redundancy, content distribution, communications, observations or measurements. In a first phase, the attributes of the data that are modified or created on a device or that are passing through the device are tracked and journaled in volatile or non-volatile storage in real-time. In a second phase, the attributes that match patterns pre-specified in a configuration are used to determine which data to replicate and which modifications to make the devices. In a third phase, the data is replicated. In a preferred embodiment, the described techniques comprise an application that runs on a host device or is embedded in a logic or memory device. The described invention is designed to be transparent for system redundancy and error recovery processes such as error correction, re-transmission on links, and raid configuration.

Abstract: A method and system for fast synchronization of computer databases using coverage status. First coverage information of a first database and second coverage information of a second database are accessed. Using the coverage information from the two databases, it may be determined which data elements from the second database are more recent than corresponding data elements from the first database. Data elements from the second database that are more recent than corresponding data elements of the first database may be transferred to the first database. In this novel manner, synchronization of two databases may take place without comparing corresponding data elements between the two databases in order to determine if a data element has been modified. By this exchange of coverage information, it is possible to transfer only changed records, in one direction, allowing for a consistent synchronization method that is typically faster than prior art methods.

Abstract: Disclosed is a data synchronization service for use in a peer-to-peer computing environment. Selected data objects are copied onto selected computing devices. A service running on each device monitors data objects for changes. When a change is detected, the service sends a change notification to the other devices so that they can update their copies of the data object. A user can access a data object from any device, knowing that he will retrieve the latest version of the data object. Instead of incurring the costs of storing a large file on every device, a user “ghosts” the file on some devices. A ghosting device stores only metadata about the file rather than the entire file. The user accesses the file through the ghost: access requests are sent to a device that holds the actual contents, and those contents are presented to the user as if they were stored locally.

Abstract: An apparatus, system, and method are disclosed for cache synchronization within a multi-tier system having multiple client-server relationships. The apparatus includes a pre-synchronization module, a locking module, and a synchronization module. The pre-synchronization module receives a pre-synchronization call from an upstream node coupled to a first downstream node. The locking module locks a first cache coupled to the first downstream node in response to a synchronization call from the upstream node. The synchronization module synchronizes source data on the upstream node with cached data on the first cache. The apparatus also may include a post-synchronization module to perform any necessary cleanup activities. Advantageously, the apparatus, system, and method reduce the likelihood of a system deadlock due to premature locking of the first downstream cache, which prevents a subsequent downstream cache from synchronizing with the first cache.
