20120144227AUTOMATIC CORRECTION OF PROGRAM LOGIC - An approach to detection and repair of application level semantic errors in deployed software includes inferring aspects of correct operation of a program. For instance, a suite of examples of operations that are known or assumed to be correct are used to infer correct operation. Further operation of the program can be compared to results found during correct operation and the logic of the program can be augmented to ensure that aspects of further examples of operation of the program are sufficiently similar to the examples in the correct suite. In some examples, the similarity is based on identifying invariants that are satisfied at certain points in the program execution, and augmenting (e.g., “patching”) the logic includes adding tests to confirm that the invariants are satisfied in the new examples. In some examples, the logic invokes an automatic or semi-automatic error handling procedure if the test is not satisfied. Augmenting the logic in this way may prevent malicious parties from exploiting the semantic errors, and may prevent failures in execution of the programs that may have been avoided.06-07-2012

20100318833METHOD FOR THE SECONDARY ERROR CORRECTION OF A MULTI-PORT NETWORK ANALYZER - A method for the error correction of a vectorial network analyzer, where a primary system calibration is initially implemented using a calibration kit. Following this, a first, secondary error correction is implemented on at least two one-port networks of the vectorial network analyzer. After this first, secondary error correction of the one-port networks of the vectorial network analyzer, a second, secondary error correction is implemented, where either two one-port networks are through-connected in an ideal manner or a measurement is implemented on a reciprocal two-port network. The corrected system-error values from the first, secondary error correction are used even in this further measurement, and overall, a high-precision, calibrated multi-port network analyzer is obtained.12-16-2010
20100318832HANG RECOVERY IN SOFTWARE APPLICATIONS - Various embodiments provide a guard mechanism that is configured to prevent transmission of synchronous function calls to hung application components. In at least some embodiments, the guard mechanism receives a synchronous function call that is intended for an application component. Before permitting the synchronous function call to be transmitted to the application component, the guard mechanism determines whether the component is hung. Responsive to determining that the component is not hung, the guard mechanism permits the synchronous function call to be transmitted to the component. If, however, the guard mechanism determines that the application component is hung, a hung component recovery process is initiated.12-16-2010

A number of processors in a self-contained network services module may execute a number of separate network service application instances associated with providing network services to the network. State information for each network service application instance may be stored within a shared memory, and a fault in one of the network service application instances may be identified based on the stored state information. The identified fault may be dynamically remedied in the one of the network service application instances.07-18-2013
20130185587Controlling a Solid State Disk (SSD) Device - A mechanism is provided for controlling a solid state disk. A failure detector detects a failure in the solid state disk. Responsive to failure detector detecting a failure, a status degrader sets a degraded status indicator for the solid state disk. Responsive to the degraded status indicator, a degraded status controller maintains the solid state disk in operation in a degraded operation mode.07-18-2013
20130191680HANDLING OF MESSAGES IN A MESSAGE SYSTEM - A messaging system comprises a message source, a message receiver and a message service. The message service is intermediate of the message source and message receiver, and a compensation component is established at the message source. A one way message is transmitted from the message source, where the one-way message is part of a plurality of one way messages of an overall business transaction. The message is received at the message service and is transmitted to the message receiver, which processes the received message. The message receiver transmits a communication indicating success or failure of the processing of the message. The system causes compensation logic defined by a compensation component to execute responsive to receiving an indication of a failure of part of the overall business transaction despite the communication from the message receiver indicated that processing of the particular one way message succeeded.07-25-2013
