Abstract: A method, a system and a computer program product for resolving conflicts between data for database integration. Data is integrated from first and second data sources to produce integrated data, and the presence of a conflict is determined between data from the first data source and data from the second data source, where one or more sets of prioritized policies for resolving conflicts is associated with data of the first and second data sources. A policy is selected from the set of prioritized policies associated with the conflicted data, where the selected policy is appropriate to resolve the conflict and includes the greatest priority. The selected policy is applied to resolve the conflict and to produce a resulting data value for the integrated data.

Abstract: Data is often populated into Configuration Management Databases (CMDBs) from different sources. Because the data can come from a variety of sources, it may have inconsistencies—and may even be incomplete. A Normalization Engine (NE) may be able to automatically clean up the incoming data based on certain rules and knowledge. In one embodiment, the NE takes each Configuration Item (CI) or group of CIs that are to be normalized and applies a rule or a set of rules to see if the data may be cleaned up, and, if so, updates the CI or group of CIs accordingly. In particular, one embodiment may allow for the CI's data to be normalized by doing a look up against a Product Catalog and/or an Alias Catalog. In another embodiment, the NE architecture could be fully extensible, allowing for the creation of custom, rules-based plug-ins by users and/or third parties.

Abstract: The present invention relates to an apparatus and method for analyzing building auditing information to identify irregular usage patterns and incorrect audit information. The auditing information, such as energy consumption, is analyzed using presence information at room or zone level. Based on pre-selected expectations, clustering is applied to data sets. By using different criteria, the clustering results are examined within every cluster and among clusters to find irregular information. Furthermore, through cross-checking with other background information, irregular usage pattern can be found and incorrect audit information can be identified, so that succeeding energy prediction and decision-support algorithms can work on a reliable set of profiles.

Abstract: Disclosed are methods and apparatus for processing correlated metadata (e.g. programmatic metadata relating to one or more episodes of a television show). Mappings, or correlations, between chunks of metadata that originated from a particular data source and metadata clusters may be determined. Inconsistencies in the correlated metadata may then be detected by a processor. An inconsistency may be an incorrect mapping, the mapping of more than one of the metadata chunks that originated from the same data source to the same metadata cluster, or that one or more of the metadata chunk have not been mapped to a metadata cluster. The mappings may then be edited so as to remove detected inconsistencies by the processor.

Abstract: A computing device detects a synchronization conflict between two versions of a file. In particular, the file may comprise a digital photo. The computing device may characterize a nature of a difference between metadata fields as immutable, mergeable, or subsumable. Core metadata fields may be defined such that a nature of a difference, or conflict, is categorized as immutable. Non-core metadata fields may be defined such that a nature of a difference, or conflict, is characterized as either mergeable or subsumable. A conflict between corresponding mergeable non-core metadata fields may be resolved by merging values of the corresponding non-core metadata fields. A conflict between corresponding subsumable non-core metadata fields may be resolved by replacing a value of a non-core metadata field of an older of the two versions of the file with a value of a corresponding non-core metadata field of a younger of the two versions of the file.

Abstract: Network security is enhanced in a multi-tenant database network environment using a query plan detection module to continually poll the database system to locate and raise an alert for suspect query plans. Security also can be enhanced using a firewall system sitting between the application servers and the client systems that records user and organization information for each client request received, compares this with information included in a response from an application server, and verifies that the response is being sent to the appropriate user. Security also can be enhanced using a client-side firewall system with logic executing on the client system that verifies whether a response from an application server is being sent to the appropriate user system by comparing user and organization id information stored at the client with similar information in the response.

Abstract: Guarded file access operations are provided for creating and using guarded file descriptors, which can detect and prevent erroneous file access operations in computer programs. A file descriptor can be associated with a guard identifier to create a guarded file descriptor. The association can be established when the file is opened, and can be maintained independently of the computer program, which ordinarily maintains its own association between files, file descriptors, and guard identifiers. Subsequent file operations using the guarded file descriptor check that the guard identifier previously associated with that file descriptor is presented, and generate errors without performing the requested file operations if the correct guard identifier is not presented. This check serves as a validation of the computer program's use of file descriptors. An error and stack trace can be generated for use in analyzing a cause of the guard violation.

Abstract: Calendar repair using a standard message may be provided. Calendar events, such as appointments and meetings, may be created and copied to a plurality of attendee calendars.

If so, a standard meeting request message comprising the correct value may be sent to update the out-of-sync property.

Abstract: A method begins by a processing module retrieving at least a threshold number of error coded data slices of a set of error coded data slices from storage units of a dispersed storage network (DSN) and identifying, based on an intentional error pattern, error coded data slices that were intentionally altered to produce identified error coded data slices. The method continues with the processing module decoding the set of error coded data slices to produce a recovered data segment and encoding the recovered data segment using an altered dispersed storage error encoding function to produce a test set of error coded data slices for comparing with corresponding error coded data slices. When the test set of error coded data slices substantially match the corresponding error coded data slices, the method continues with the processing module indicating that the recovered data segment has not been corrupted.

The information in the HDFS is taken as ground truth and any meta table or assignment problems that are inconsistent with the HDFS is deemed wrong and removed.

Abstract: A computer cluster can be divided into a plurality of failure scopes and a voting constraint can be enforced. The voting constraint can allow a portion of the cluster to provide the service if a majority of health votes from cluster members is obtained by that portion. A loss of connectivity between a first failure scope, which has a majority of cluster members in the cluster, and one or more other failure scopes in the cluster can be detected. The loss of connectivity can be such that the first failure scope does not have connectivity to a member in any other failure scope in the cluster. In response to detecting the loss of connectivity, a split brain situation in the cluster can be automatically protected against by preventing the first failure scope from providing the service.

A storage stores two or three higher-order layers within a domain ontology (DO) layer including specs of the equipment class and the properties, a meta-ontology (MO) layer including specs of metadata of the class and the properties, and an axiomatic ontology (AO) layer including the metadata specs. An access controller controls access to the smart grid ontology so that access is allowed only from a database (DB) or an adapter of a lower-order layer existing in a limited number of specific nodes for a higher-order node. An updater updates the DO layer so that the DO layer is consistent with the MO layer.

Abstract: Systems and methods for performing data replication are disclosed. Determining whether to update replicated data typically involves comparison of readily obtainable attributes of a given source file and its corresponding replicated file. Such attributes can be obtained from, for example, metadata. In certain situations, an additional assessment of the source and replicated files can be beneficial. For example, if integrity of an existing replicated file's content is maintained, one may not want to re-replicate the corresponding source file. For large source files, such a decision can provide substantial reductions in expenditures of available computing and network resources. In certain embodiments, a threshold for identifying such large files can be based on one or more operating parameters such as network type and available bandwidth. In certain embodiments, replication file's integrity can be checked by calculating and comparing checksums for the replication file and its corresponding source file.

Abstract: Presented herein are methods of continuously verifying data and repairing errors introduced during replication. In a particular embodiment, a primary data store sends out information sufficient to create a checkpoint together with a checksum for the data being verified at that checkpoint. At the secondary data store, a checkpoint is created in accordance with the checkpointing information, and a checksum is calculated over the indicated data at the created checkpoint. If the calculated checksum disagrees with the received checksum, additional checksums are calculated over subranges of the indicated data and compared with corresponding checksums over the data at the primary data store. The checksums at the primary data store may be requested from the primary data store or calculated locally based on the received overall checksum. Once an erroneous entry is identified, it can then be re-replicated from the primary data store to restore data consistency.
