48 results about "Core dump" patented technology

In computing, a core dump, crash dump, memory dump, or system dump consists of the recorded state of the working memory of a computer program at a specific time, generally when the program has crashed or otherwise terminated abnormally. In practice, other key pieces of program state are usually dumped at the same time, including the processor registers, which may include the program counter and stack pointer, memory management information, and other processor and operating system flags and information. A snapshot dump (or snap dump) is a memory dump requested by the computer operator or by the running program, after which the program is able to continue. Core dumps are often used to assist in diagnosing and debugging errors in computer programs.

Locating and altering sensitive information in core dumps

A core dump is processed to locate and optionally alter sensitive information. A core dump copy is created from at least a portion of an original core dump. Also, at least one input parameter is provided that corresponds to select information to be identified in the core dump copy and address information associated with the core dump copy is defined that corresponds to at least one of addresses where the select information can be altered and addresses where the select information should not be altered. Each occurrence of the select information located within the core dump copy is identified and optionally replaced with predetermined replacement data if the occurrence of the select information is within the addresses where the select information can be altered.

Managing process state information in an operating system environment

A technique for managing process state information involves pushing process state information from the kernel space to the user space in the event of an application crash and generating a core file at the user level instead of at the kernel level. Handling the process state information at the user level instead of at the kernel level provides more flexibility in the generation and management of a core file as compared to systems that use kernel code to generate and manage the core file. A core dump application at the user level can be programmed to forward the core file to another system that has permanent storage capacity available. Additionally, the core dump application can be programmed to compress the process state information and / or to extract only certain information from the process state information while generating the core file.

Core dump privacy during application failure

Embodiments of the present invention address deficiencies of the art in respect to core dump generation during application fault handling and provide a method, system and computer program product for privacy preservation of core dump data during application fault handling. In an embodiment of the invention, a method for privacy preservation of core dump data during application fault handling can be provided. The method can include receiving a crash signal for an application and generating a core dump with object data for the application. The method further can include obfuscating the object data in the core dump and writing the core dump with obfuscated object data to a file. In this way, the privacy of the object data in the core dump can be preserved.

Failure Detection and Fencing in a Computing System

A method, computer program product, and system for detecting and fencing off a failed entity instance so that failover time in the computing system is reduced. Upon detection of a failed entity, for example a failed process, a signal handler invokes an operating system interface to fence off the failed instance from modifying its persistent state, so that the entity may be re-instantiated prior to termination of the failed instance. This approach reduces failover time and eliminates split-brain problems without compromising access to the failed instance to obtain diagnostic information, core dumps, and the like.

Method and apparatus for generating dynamic microcores

A method of generating a microcore file, which is a subset of a full core dump, for a networked storage system includes generating a microcore file according to a microcore specification, and dynamically defining the microcore specification at runtime of the network storage system. The microcore specification is dynamically defined with information provided by results of an event that triggers the generation of the microcore file. After the microcore specification is defined, a region of a system memory is identified according to the microcore specification. The method further includes dumping the data from the region of the system memory into the microcore file.

Method for capturing core dump of a service module

A bootstrap program is loaded into an area of memory previously occupied by a run time program in a service module. The bootstrap program is loaded after the service module is reset due to an error. The service module does not have a persistent storage. The bootstrap program captures a memory image of the memory. The captured memory image of the memory is compressed and transferred to a control module to be stored in a persistent storage of the control module. The control module receives captured memory images from one or more service modules.

System and method of selection and communication of a disk for storage of a coredump

This invention provides a system and method for selecting and communicating a single disk (a “coredump disk”) for use in a coredump procedure by a failed file server (or filer). A selection method on the failed filer determines the “best candidate” coredump disk according to a predetermined set of criteria. For example, the available disks that can receive coredump data are located and ordered so as to prefer disks that best match the coredump data size requirement, are least likely to be needed for normal service by the server; and require the least preparation to receive coredump data. Appropriate attributes on the selected coredump disk are written to indicate that a coredump is in progress, and the location of the coredump data. Upon reboot of the failed filer (or takeover by a cluster partner), the coredump disk is identified and the coredump data recovered by reading back appropriate attributes.
