Abstract: A congestion and failure detector and localizer running on a storage array locally monitors ports of the storage array for IO failures and local link errors and remotely monitors ports of host initiators and host-side and storage array-side switches for link errors. Based on whether the local link error rate is increasing at any ports, whether IO failures are associated with a single host initiator port, and whether link error rate is increasing on both the host initiator and initiator-side switch, the congestion and failure detector and localizer generates a flag indicating either a physical link problem between the storage array and adjacent switch, ISL physical issue or spreading congestion, host initiator-side physical link problem, or path congestion. The flag identifies the storage array port, issue type, link, fabric name, and host initiator.

The dynamic configuration may be defined per method, argument, variable, and/or data structure. The dynamic configuration may be initially deployed with default heuristics defined in the client library.

Abstract: A server implementing a service receives a request from a client computing system and stores the request in a cache, along with a correlation identifier. The server returns a response to the request, along with a correlation identifier (ID). When a trigger input is received, indicating that a problem has been encountered at the client computing system, a diagnostic data generation system on the service accesses the cache and generates diagnostic data for the request corresponding to the correlation ID. The diagnostic data corresponding the correlation ID is then provided to a support data storage system where it can be combined with diagnostic data from the client computing system, to be accessed by a support computing system. This reduces consumption of computing resources, such as processing time, memory initialization and/or network bandwidth.

The host sends the first ownership change command to the storage subsystem then determines whether the storage subsystem responded with an error message. Upon responding to a determination that the storage subsystem responded with the error message, the host determines whether the storage subsystem indicated an error associated with an ownership change.

Upon receiving a list of logical unit number associations from the storage subsystem, the host responds to receiving a list of logical unit number associations. The host performs a second ownership command to determine whether the list of logical unit number associations matches an ownership defined in the ownership change command.

Abstract: During software development, both before and after release, information may be collected and stored that may provide insight to developers as a generalized service. For example, data from past debugging sessions, source code in various repositories, bug repositories, discussion groups, and various documents may provide relevant information for software developers to fix current problems when this information is coherently matched with the problem. Using various sources, a system may mine the stored data to give the current developer information related to past code development, and reveal why the code changed throughout previous development. Using sophisticated analyses to identify similar code patterns across multiple large software projects, discovering patterns in normal and abnormal uses of particular software interfaces, and employing other mining techniques, a developer may find domain-specific information to facilitate ongoing software development.

Abstract: Data stored in relational databases can be retrieved using a relational database query language, while data stored in a multidimensional database is typically retrieved using a multidimensional database query language. However, most users do not have a functional working knowledge of multidimensional database query languages, which leaves large amounts of data inaccessible. Further, while some relational database query languages may be translated into a multidimensional database language, the information generated by such translations is often unusable, or returns large numbers of errors. In order to obtain effective translation of a relational database query language to a multidimensional database query language effective translation and filtering needs to occur. Using effective mapping and retrieval of database metadata along with effective, customizable business logic filtering of query components, more effective and reliable results may be achieved.

Abstract: A mechanism for isolating failures in a digital system is provided. In one embodiment, a fault table is defined for each unit in the system. Related faults are ordered within the table to reflect the time-order in which the faults would be activated during operation of the associated unit. When multiple related faults are reported for a given unit in the system, the fault that is first located when a linear search of the corresponding fault table is conducted is considered the source of the failure within the unit. If faults are reported for multiple units, the source of the failure for the system is identified using at least one of primary and second priority values assigned to the faults, timestamps obtained when the faults are reported, and an order in which the faults are logged.
