Abstract: A first computer receives a first and a second test sample. The first computer executes the first and second test sample. The first computer determines that the value exposed by a first parameter in the second test sample is different from the value exposed by the first parameter in first test sample.

The first computer determines the value exposed by the second parameter in the second test sample is different from the value exposed by the second parameter in the first test sample and the value exposed by the second parameter in the second test sample is equivalent to the value exposed by the first parameter in the second test sample. The first computer adds the second parameter to the first value driven equivalence class and creates a generalized test case, including at least the first value driven equivalence class.

Abstract: A method, for handling partially inconsistent states among members of a cluster in an erratic storage network that responds to requests from a client, includes assigning a unique commit identifier corresponding to each successive modification of state of the cluster when an update request has been successfully completed and correlating an incoming request to a given member of the cluster with any commit identifiers necessary to satisfy the request. The method further includes detecting, on the incoming request to the given member of the cluster, whether the commit identifiers necessary to satisfy the request have been applied to the given member, and processing the incoming request based on whether the commit identifiers necessary to satisfy the request have been applied to the given member. Operation of the members can be asynchronous.

Abstract: Aspect methods, systems and devices may be configured to create/capture checkpoints without significantly impacting the performance, power consumption, or responsiveness of the mobile device. An observer module of the mobile device may instrument or coordinate various application programming interfaces (APIs) at various levels of the mobile device system and constantly monitor the mobile device (via a low power process, background processes, etc.) to identify the normal operation patterns of the mobile device and/or to identify behaviors that are not consistent with previously computed normal operation patterns. The mobile device may store mobile device state information in a memory as a stored checkpoint when it determines that the mobile device behaviors are consistent with normal operation patterns, and upload a previously stored checkpoint to a backup storage system when it determines that the mobile device behaviors are not consistent with normal operation patterns.

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.

A first weight factor is determined from a first quantile distribution representation based on a value of the diagnostic parameter, where the first quantile distribution representation represents a quantile distribution of values of the diagnostic parameter of a set of known failed disks.

A third weight factor is determined for the diagnostic parameter for the target storage disk based on the first weight factor and the second weight factor and a probability of potential disk failure of the target storage disk is determined based on the third weight factor.

According to one embodiment, diagnostic parameters are received which are collected from a set of known working disks and a set of known failed disks of a storage system. For each of the diagnostic parameters, a first quantile distribution representation is generated for the set of known working disks, and a second quantile distribution representation is generated for the set of known failed disks. The first quantile distribution representation and the second quantile distribution representation of each of the diagnostic parameters are then compared to select one or more of the diagnostic parameters as one or more disk failure indicators for predicting future disk failures.

Abstract: Embodiments provide systems and methods having an engine that gives stateless applications attributes of a ‘stateful’ process. To accomplish this end, a ‘snapshot’ of a transaction at a given point is taken and persisted until receiving confirmation that the transaction is completed. The snapshot may be a snapshot of data flowing in a stateless messaging system. The snapshot is maintained until confirmation that all intended recipients to which the transaction relates to have completed the steps they need to for the given transaction. The snapshot may be formed into a message and reflowed to an intended recipient to ensure that the recipient receives the message in the event that the initial delivery is unsuccessful.

Abstract: Approaches for problem determination and resolution process cross communication are provided. Embodiments provide cross communication of a problem determination and resolution among similar data center devices. Specifically, symptoms of an error condition encountered for one data center device are captured by a first enterprise group, along with an associated resolution solution, and made available to an another enterprise group managing a commonly configured data center device, which may be faced with a similar error condition. The error signature and resolution steps captured by the first enterprise group are subsequently made available within and across multiple management domains operating within a common model (e.g., a publication-subscription system). Within this model, both the originator of the error determination and resolution (i.e., publisher), and one or more commonly configured data center devices susceptible to the same error condition (i.e.
