Systems and methods for managing data, such as metadata. In one exemplary method, metadata from files created by several different software applications are captured, and the captured metadata is searched. The type of information in metadata for one type of file differs from the type of information in metadata for another type of file. Other methods are described and data processing systems and machine readable media are also described.

Methods And Systems For Managing Data

A system comprising a plurality of path computation elements (PCEs) configured to communicate with an ingress node, jointly compute a core tree for an inter-domain point-to-multipoint (P2MP) tree across a plurality of network domains, and independently compute a plurality of sub-trees in at least some of the network domains, wherein the core tree connects the ingress node to a boundary node (BN) in each one of the network domains that have a destination node and each sub-tree connects the BN to a plurality of destination nodes in one of the network domains that have a destination node.

Systems and methods for providing a user interface including earlier versions of data. In one implementation, computer program product is provided. The computer program product generates a user interface. The user interface includes a view display area for presenting a current view and a history view display area for presenting a history view associated with the current view. The history view includes one or more first visual representations of corresponding earlier versions of the current view. The user interface also includes an input control for initiating a restoration of the current view according to at least a portion of an earlier version of the one or more earlier versions.

User interface for backup management

Systems and methods are provided for storing and restoring digital data A method includes receiving, a first user input requesting that a backup interface be displayed, displaying the backup interface, the backup interface including a display area for presenting at least a first visual representation of an earlier version of a current view and a visual representation of the current view, the earlier version including a first element, receiving, while the backup interface is displayed, a second user input requesting that the current view be modified according to the earlier version, at least with regard to the first element, animating the modification of the first element as moving from the visual representation of the earlier version to the visual representation of the current view, and modifying, in response to the second user input, the current view according to the earlier version, at least with regard to the first element

Replicated instances in a database environment provide for automatic failover and recovery. A monitoring component can periodically communicate with a primary and a secondary replica for an instance, with each capable of residing in a separate data zone or geographic location to provide a level of reliability and availability. A database running on the primary instance can have information synchronously replicated to the secondary replica at a block level, such that the primary and secondary replicas are in sync. In the event that the monitoring component is not able to communicate with one of the replicas, the monitoring component can attempt to determine whether those replicas can communicate with each other, as well as whether the replicas have the same data generation version. Depending on the state information, the monitoring component can automatically perform a recovery operation, such as to failover to the secondary replica or perform secondary replica recovery.

Failover and recovery for replicated data instances

Approaches described herein may be used for provisioning of databases that requires a bulk transfer of data within a distributed computing environment, such as a grid. The approaches do not require the manual intervention of a DBA to, for example, transfer a tablespace between the file systems of operating systems. Instead, the tablespaces may be provisioned automatically and dynamically by a grid computing system whenever it determines the need to dynamically provision a database. In addition, as copies of tablespaces are provisioned, synchronization mechanisms can also be automatically provisioned to keep the tablespaces and their copies in sync.

Automatic and dynamic provisioning of databases

Direct memory accessed is used to perform database operations between two or more machines. Data is read from a first buffer located on a first machine. The data was written into the first buffer in response to the data being written into a second buffer at a second machine. In one embodiment, based, at least in part, on whether the data represents a partial read, a determination is made as to whether to transmit, to the second machine, an explicit acknowledgement that the data was read from the first buffer. In another embodiment, based on whether the amount of unacknowledged data received by the first machine from the second machine exceeds a threshold quantity, a determination is made as to whether to transmit, in response to the data being read from the first buffer, any acknowledgement that the data was read from the first buffer.

Transmitting acknowledgements using direct memory access

Direct memory accessed is used to perform database operations between two or more machines. A first segment of memory is allocated for a second machine, where at least one of the first machine and second machine is a database server. During performance of a database operation that involves the transfer of data from the second machine to the first machine, data in the first segment of memory is buffered in response to the second machine writing the data to a second segment of memory on the second machine.

Using direct memory access for performing database operations between two or more machines

A distributed code development environment includes baseline code that is logically divided into a plurality of labels, each including a plurality of transactions authored by respective developers. A computer-implemented method for identifying intermittent errors in the baseline and determining whether errors generated by a test of transactions are intermittent or consistent may include steps of providing the baseline code and providing the plurality of transactions, each of the plurality of transactions including code authored by a developer. A selected test may be carried out on a selected one of the plurality of transactions, the selected test generating an error that represents an unsuccessful completion of the selected test. The generated error may then be compared against errors generated by the selected test on other transactions or labels. The generated error may be identified as intermittent with respect to the transaction and spurious in the baseline if a selected number of errors generated by the selected test on the other transactions or labels are identical or similar to the generated error, according to a selected metric.
