Abstract: A method and apparatus are provided for pre-allocating non-initialized blocks of data in a file system. Each file contains a primary i-node to maintain file metadata. A secondary i-node is created and associated with the primary i-node. The secondary i-node contains non-initialized data blocks, and the primary i-node contains valid and initialized data blocks. A write operation to a non-initialized data block in a pre-allocated range stored in the secondary i-node directs the data block from the secondary i-node to the primary i-node.

Abstract: A management system has a reconciliation engine that reconciles information describing resources from a computer network service and stores reconciled information in a database. An editing engine or server is used to access and search reconciled information in the database based on at least one search criterion. Preferably, the search criterion is user-entered. The editing engine is then used to create at least a portion of a service model of the computer network service using reconciled information obtained through accessing and searching the database. Preferably, creating the service model is done with a graphical user interface application that enables a user to graphically build and modify aspects of the service model. When the service model is created or updated, a publishing engine or server is used publish at least a portion of the service model to one or more impact managers of the computer network service.

Abstract: Some aspects include reception of a plurality of search results, selection of a graphical format in which to present the search results from a plurality of graphical formats based on metadata of the plurality of search results, and presentation of the plurality of search results in the selected graphical format.

Abstract: A method for online propagation of data updates, the method including initiating a record update process for any of a plurality of records in a system responsive to a modification of a trigger data item, where the process is performed while the system is online, creating an update process timestamp indicating a time at which the record update process is begun, and determining if a last-modified timestamp associated with any of the records indicates an eariler time than the update process timestamp, and, if so updating the record to reflect the modification to the trigger data item, and modifying the last-modified timestamp to reflect a time that is later than the update process timestamp.

Abstract: A method for validating SRS registry transaction data includes receiving OLTP transaction data from a first database, parsing the OLTP transaction data, and comparing the parsed OLTP transaction data to one or more of a set of profiles. Each of the one or more of the set of profiles includes metadata in XML files. The method also includes caching the parsed OLTP transaction data in a first data cache, receiving log data associated with the OLTP transaction data; and caching the log data in a second data cache. The method further includes correlating the parsed transaction data cached in the first data cache with the log data cached in the second data cache.

Abstract: The subject disclosure relates to querying of column based data encoded structures enabling efficient query processing over large scale data storage, and more specifically with respect to complex queries implicating filter and/or sort operations for data over a defined window. In this regard, in various embodiments, a method is provided that avoids scenarios involving expensive sorting of a high percentage of, or all, rows, either by not sorting any rows at all, or by sorting only a very small number of rows consistent with or smaller than a number of rows associated with the size of the requested window over the data. In one embodiment, this is achieved by splitting an external query request into two different internal sub-requests, a first one that computes statistics about distribution of rows for any specified WHERE clauses and ORDER BY columns, and a second one that selects only the rows that match the window based on the statistics.

Abstract: A method, system, and computer-readable storage medium are disclosed for recovering a backup catalog from replicated data. A set of catalog metadata may be stored in a metadata object on a first storage device. The set of catalog metadata may describe a plurality of files stored in an archive. The metadata object and the archive may be copied to a second storage device, thereby generating a replicated metadata object and a replicated archive on the second storage device. The set of catalog metadata may be imported from the replicated metadata object into a destination backup catalog. The destination backup catalog describes the plurality of files stored in the replicated archive.

Abstract: Systems and methods for storing and accessing data. A query language statement may reference a plurality of data sets and a plurality of algebraic relations between the data sets may be composed from the query language statement. The algebraic relations may be used to define new data sets and to optimize access to data sets. A store of algebraic relations may be accumulated over time. Alternative collections of algebraic relations may be generated and evaluated to determine an optimized collection of algebraic relations to use in calculating and providing a requested data set. The optimization may be performed using the algebraic relations rather than retrieving underlying data sets from storage. As a result, optimization may be performed at processor speeds to minimize the amount of time required for data to be retrieved from slower storage.

Abstract: An encrypted file storage solution consists of a cluster of processing nodes, external data storage, and a software agent (the “File System Watcher”), which is installed on the application servers. Cluster sizes of one node up to many hundreds of nodes are possible. There are also remote “Key Servers” which provide various services to one or more clusters. The preceding describes a preferred embodiment, though in some cases it may be desirable to “collapse” some of the functionality into a smaller number of hardware devices, typically trading off cost versus security and fault-tolerance.

Abstract: A method and system for migrating source data from one or more databases to a destination database, wherein the destination database is selected based on power consumption of the destination database. A data migration server determines which destination database should be selected by selecting a number of candidates and comparing the power consumed, the available space and the maximum monthly power consumption limit. A user intervention policy is created to evaluate which data should be moved to a destination database. A “payback period” is calculated to determine the amount of time that will elapse before savings are realized.
