  • Publication number: 20140032964
    Abstract: Techniques for recovering from session failures between clients and database servers are described herein. A session may be established between a client and a first database server to handle a database query for the client. A command of the session may be received by the first database server from the client. Data requested by the command may be retrieved. Prior to responding to the command, the data is spooled to a session state stored in a repository of the first database server, and the session state is replicated to one or more additional database servers. The session state stored in the repository of the first database server enables the first database server and client to recover from a failure of the session. The replicated session state enables the additional database server(s) to reestablish the session and respond to the command, instead of the first database server, if the session fails.

    Abstract: In one example, a method for implementing recovery segments includes sending an application message from a parent process executed by a first computing device to a child process executed by a second computing device and identifying a dependency created by the application message. This identified dependency is included in a dependence set of the child process and saved. A checkpoint is generated by the parent process and a checkpoint message that includes dependency information is sent from the parent process to the child process. The child process modifies the dependence set according to the dependency information and generates a second checkpoint that is saved in nonvolatile memory of the second computing device. Upon occurrence of a failure of the parent process, the child process reverts to a most recent checkpoint generated by the child process that does not include the effects of processing an orphan message.

    Abstract: An approach to providing auto recovery of data sets in volumes. When an error condition results from an attempt to access an unintentionally deleted data set, an event is generated and sent to other systems with access to the volume in which the data set existed. The volume is also locked to prevent corruption during the recovery process. A system that has the unintentionally deleted data set open retrieves location information for the data set from control blocks in the system's memory. This location information is used to build a new entry for the data set in the VTOC for the volume. When the data set is thus recovered, the data set is validated, the lock removed, and the data set is made available to the systems sharing the volume.

    Abstract: Described are embodiments directed at persistent handles that are used to retain state across network failures and server failovers. Persistent handles are requested by a client after a session has been established with a file server. The request for the persistent handle includes a handle identifier generated by the client. The server uses the handle identifier to associate with state information. When there is a network failure or a server failover, and a reconnection to the client, the handle identifier is used to identify replayed requests that if replayed would create an inconsistent state on the server. The replayed requests are then appropriately handled.

  • Publication number: 20120297248
    Abstract: A memory device recognizes that data corruption is present in a block. In response, rather than skip the block and continue write operations into a different uncorrupted block, the memory device continues to write data into the corrupted block. The memory device may write data on the basis of logical groups. The logical groups may be smaller than a block and larger than a page, but other sizes are also possible. In response to write corruption in the block (e.g., from power loss during a write operation), the memory device may skip certain parts of the block and continue writing into the block. For example, the memory device may skip the remainder of the page range in which the logical group was going to be written when data corruption occurred, and instead write that logical group into the block from the start of the next logical group unit, the next available page, or any other boundary.

  • Publication number: 20120254652
    Abstract: The monitoring by a monitoring node of a process performed by a monitored node is often devised as a tightly coupled interaction, but such coupling may reduce the re-use of monitoring resources and processes and increase the administrative complexity of the monitoring scenario. Instead, fault detection and recovery may be designed as a non-proprietary service, wherein a set of monitored nodes, together performing a set of processes, may register for monitoring by a set of monitoring nodes. In the event of a failure of a process, or of an entire monitored node, the monitoring nodes may collaborate to initiate a restart of the processes on the same or a substitute monitored node (possibly in the state last reported by the respective processes). Additionally, failure of a monitoring node may be detected, and all monitored nodes assigned to the failed monitoring node may be reassigned to a substitute monitoring node.

    Abstract: Storage servers use a fast, non-volatile or persistent memory to store data until it can be written to slower mass storage devices such as disk drives. If the server crashes before a write can complete, the data remains safely stored in non-volatile memory. If the data cannot be committed to disk when the server reboots (e.g. because the destination mass storage device is unavailable), it is stored in a file. When the disk reappears, the data in the file may be used to restore a file or filesystem on the disk to a consistent state.

    Abstract: A backup image generator can create a primary image and periodic delta images of all or part of a primary server. The images can be sent to a network attached storage device and a remote storage server. In the event of a failure of the primary server, the failure can be diagnosed to develop a recovery strategy. Based on the diagnosis, at least one delta image may be applied to a copy of the primary image to generate an updated primary image at either the network attached storage or the remote storage server. The updated primary image may be converted to a virtual server in a physical to virtual conversion at either the network attached storage device or remote storage server and users may be redirected to the virtual server. The updated primary image may also be restored to the primary server in a virtual to physical conversion. As a result, the primary data storage may be timely backed-up, recovered and restored with the possibility of providing server and business continuity in the event of a failure.

    Abstract: A method for fast and efficient data downloading in wireless communications. The method includes ways to download file data of a large size from a server (access point) to a user's client (mobile device) at high speed and efficiency by using both mmWave wireless communication and conventional wireless communication (WiFi, 3G, etc.). A server transmits packetized file data to a client. The file data is transmitted as data packets via mmWave. In parallel, the server transmits check packets (roll-call packets) corresponding to the data packets. As a test at the time of establishing links, the latency for each communication line is measured. The receiver side, upon completion of receiving the check packets, checks whether their corresponding mmWave packets have arrived. If any corresponding mmWave packet has not arrived, it is determined that the mmWave packet has been lost and a retransmission request is immediately returned to the server via WiFi.

  • Publication number: 20120210163
    Abstract: Embodiments of the present invention provide backup and restoration functions for a storage device of a PCI-Express (PCI-e) type that support a low-speed data processing speed for a host. Specifically, embodiments of this invention provide backup and restoration functions for one or more (i.e., a set of) semiconductor storage devices (SSDs). In general, the present invention provides an alarm unit and a secondary power supply coupled to a backup controller. The backup controller is coupled to a backup storage device. When a primary power supply is deactivated (e.g., fails), an alarm unit and the secondary power supply is activated. In response to this activation, the backup controller will backup any data stored on any SSDs of the storage system (as well as any data stored in main memory of the storage system or in main memory of any host server connected thereto).

  • Publication number: 20120198268
    Abstract: Embodiments enable recovery of push notification channels via session information associated with user identifiers. A proxy service creates session information describing push notification channels (e.g., subscriptions) for a user and associates the session information with a user identifier. The session information is stored in a cloud service or other storage area separate from the proxy service. After failure of a user computing device or the proxy service, the session information is obtained via the user identifiers and the push notification channels are re-created with the session information. In some embodiments, the proxy service enables delivery of the same notification to multiple computing devices associated with the user identifier.

  • Publication number: 20120179934
    Abstract: A method and non-transitory computer-readable medium are disclosed for extending a hold timer that binds an application-layer session when a transport-layer out-of-order message queue includes an out-of-order message for the application-layer session. An application receives an application-layer message from transport protocol logic that is configured to deliver in-order application-layer messages to the application. The received application-layer message is a next in-order application-layer message for an application-layer session that is bound by a hold timer. After an amount time has passed, the application detects an expiration of the hold timer. In response, rather than immediately tearing down the application-layer session, the application inspects an out-of-order queue of the transport protocol logic. The hold timer is extended when the out-of-order queue includes an out-of-order application-layer message for the application-layer session.

  • Publication number: 20120117419
    Abstract: This disclosure provides apparatus, methods and systems for error correction in multi processor systems. Some implementations include a plurality of computing modules, each computing module including a processor. Each processor may include processing state. In some other implementations, each computing module may also include a memory. Upon receiving a signal to perform a partial re-synchronization, a hash of each processor's state data may be performed. In some embodiments, a hash of at least a portion of each computing module's memory data may also be performed. The hashes for each processor are then compared to determine majority hashes and possible minority hashes. Upon identifying a minority hash, the computing module that produced the minority hash may receive new processing state data from one of the computing modules that produced a majority hash.
