  • Publication number: 20140082415
    Abstract: A quick buffer validity check can optionally be performed when a potential invalidity of the content of a buffer is identified. The identifying of the potential invalidity condition can include determining that a most recent lifecycle management event timestamp is more recent than a most recent buffer validity check timestamp for the buffer. To determine whether the buffer contents need to be refreshed, a list of the last changed timestamps for the constituent elements of the buffer can be compared to a new list. If the new list and the old list are not identical, the buffer can be rebuilt.

  • Publication number: 20130339787
    Abstract: Aspects of the present invention provide a tool for analyzing and remediating an update-related failure. In an embodiment, a failure state of a computer system that has been arrived at as a result of an update is captured. A semantic diff that includes the difference between the failure state and at least one of an original state or a completion state is then computed. This semantic diff is transformed into a feature vector format. Then the transformed semantic diff is analyzed to determine a remediation for the update. Failure and/or resolution signatures can be constructed using the semantic diff and contextual data, and these signatures can be used in comparison and analysis of failures and resolutions.

  • Publication number: 20130311823
    Abstract: A resiliency system detects and corrects memory errors reported by a memory system of a computing system using previously stored error correction information. When a program stores data into a memory location, the resiliency system executing on the computing system generates and stores error correction information. When the program then executes a load instruction to retrieve the data from the memory location, the load instruction completes normally if there is no memory error. If, however, there is a memory error, the computing system passes control to the resiliency system (e.g., via a trap) to handle the memory error. The resiliency system retrieves the error correction information for the memory location and re-creates the data of the memory location. The resiliency system stores the data as if the load instruction had completed normally and passes control to the next instruction of the program.

    Abstract: Disclosed is a microcomputer such that even when a program cannot be executed in a CPU of the microcomputer due to an external noise, an unstable power-supply voltage, and other causes, and an fatal error such as runaway occurs, returning to the original state is possible within an extremely short time while preferably avoiding initialization of the entire system. During execution of normal software processing, an interrupt signal and a reset signal are output at an arbitrary time, and if it is determined that a CPU of a microcomputer gets into a runaway state, data which has been stored in a RAM as recovery information is read out, and the CPU is recovered to the state before the runaway. Because such recovery from a fatal error occurs within a short time, software which is being executed can continue its processing as if the fatal error had not occurred.

    Abstract: Processing for file system volume error detection and processing for resultant error correction are separated to support system availability and user satisfaction. File system volumes for storing data structures are proactively scanned while the volumes remain online to search for errors or corruptions thereon. Found errors are scheduled to be corrected, i.e., spot corrected, dependent on the severity of the identified errors, error correction scheduling and/or at the determination of a file system administrator and/or user, to assist in maintaining minimal user and file system impact. When spot correction is initialized, one file system volume at a time is taken offline for correction. Spot correction verifies prior logged corruptions for the offline volume, and if independently verified, attempts to correct the prior noted corruptions. Volumes are retained offline only for the time necessary to verify and attempt to correct prior noted volume corruptions.

  • Publication number: 20120005529
    Abstract: A system and method can support a compensation work. The system includes one or more compensation functions that use a process state to realize the compensation work associated with a forward work, wherein the compensation work is executed at a different runtime from an execution time of the forward work, and wherein the process state contains data needed to execute the compensation work. The system also includes a process execution engine that can dynamically manage process state to make the state available to the compensation functions. The process state is retrieved based on a closure data structure that holds an expression and an environment of variable bindings, in which the expression is to be evaluated.

  • Publication number: 20110296241
    Abstract: A method, system, and computer usable program product for accelerating recovery in an MPI environment are provided in the illustrative embodiments. A first portion of a distributed application executes using a first processor and a second portion using a second processor in a distributed computing environment. After a failure of operation of the first portion, the first portion is restored to a checkpoint. A first part of the first portion is distributed to a third processor and a second part to a fourth processor. A computation of the first portion is performed using the first and the second parts in parallel. A first message is computed in the first portion and sent to the second portion, the message having been initially computed after a time of the checkpoint. A second message is replayed from the second portion without computing the second message in the second portion.

  • Publication number: 20110296238
    Abstract: The re-encryption of data can be performed with independent cryptographic agents that can automatically encrypt and decrypt data in accordance with cryptographic regions, such that data within a single cryptographic region is encrypted and decrypted with the same cryptographic key. An “in-place” re-encryption can be performed by reading data from a chunk in an existing cryptographic region, shrinking the existing cryptographic region past the chunk, expanding a replacement cryptographic region over the chunk, and then writing the data back to the same location, which is now part of the replacement cryptographic region. An “out-of-place” re-encryption can be performed by reading data from a chunk in an existing cryptographic region and then writing the data back to a location immediately adjacent that is part of a replacement cryptographic region. After the re-encrypted data is “shifted”, the cryptographic regions can be expanded and contracted appropriately, and another chunk can be selected.

  • Publication number: 20110246825
    Abstract: An image forming apparatus includes a storage part, an error detection part, a connection detection part, a determination part and a data transfer part. The storage part stores data. The error detection part detects whether data transfer between the storage part and an external storage device failed. The connection detection part detect whether an external storage device is connected. The determination part determines whether the external storage device whose connection is detected by the connection detection part is coincident with the external storage device which failed in the data transmission. When the determination part determines the coincidence, the data transfer part transfers the transfer failed data between the storage part and the external storage device whose connection is detected by the connection detection part.

  • Publication number: 20110214015
    Abstract: A method of detecting a network hang and restoring an application that communicates on a connection giving rise to the network hang. A user experience may be improved by providing the user with an option to restore the hung application without losing unsaved data or state information. The network hang may be detected when the user tries to terminate the application. The method may include determining whether the network hang is recoverable, which may involve diagnosing a type of the hang. If recoverable, a network connection reset mechanism may be triggered by instructing a network stack of the computer to terminate the network connection.
