Appl. No.:

12/133193

International Classification:

G06F 17/30

US Classification:

707637

Abstract:

Methods, systems and apparatus, including computer program products, for propagating data across shards of a database system are described. According to one method, a first request that includes instructions to place a second request in a queue of a second shard is placed in a queue of a first database shard, and the change is committed to the records of the first shard. A queue processor polling the queue fetches and dispatches the first request, placing the second request in a queue of a second database shard. The second request includes instructions for making the change to the second shard. A queue processor of the second database shard polls the queue of the second database, fetches the second request, and dispatches it to make the change on the second database shard.

International Classification:

G06F 9/44

US Classification:

717135

Abstract:

An analysis tool analyzes a software system by simulating runtime binding in order to identify function-level code dependencies. The tool receives a list of one or more entry point functions and identifies other functions that can be invoked if the entry point functions are executed. The tool generates a tracker graph having tracker nodes representing classes that can be instantiated from the entry points. Each tracker node identifies functions/methods in that class that can be invoked from the entry points. If the software system uses an object-relational mapping to a database, the tracker graph also identifies the portions of the database that can be accessed from the entry points. The tool can be used to partition the functionalities of the software system into core and non-core functionalities in order to support upgrading while maintaining high-availability.

Abstract:

One or more requests are received from a first system. The requests are queued in a queue. A serialization group is determined for a request and the request is associated with the determined serialization group. At least a subset of the requests from the queue is transmitted to a second system if the second system is available, including transmitting requests in a respective serialization group to the second system serially in accordance with an ordering of the requests within the respective serialization group.

US Classification:

713320, 713300

Abstract:

A method of operation of a data storage system includes: providing a standby power source; detecting activity on a communication channel with an upstream re-driver powered with the standby power source; generating a signal-detect output from the upstream re-driver based on the activity; determining a link status with a power control unit based on the signal-detect output, the power control unit powered with the standby power source; and generating a power output from a power supply unit based on the link status, the power supply unit controlled by the power control unit.
