Oracle Assigned Thirteen Patents

Executing conditional command on object stored in storage
Oracle International Corporation, Redwood Shores, CA, has been assigned a patent (10,860,534) developed by Sawhney, Aditya, Erie, CO, for “executing a conditional command on an object stored in a storage system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Each object is associated with one root metadata record and one or more version-specific metadata records, each corresponding to a version of object data. A conditional command may be conditioned upon whether an object is stored in a storage system. Whether the condition is satisfied is determined based on whether a root metadata record of the object exists. If the condition is satisfied, then metadata is updated to reflect execution of the conditional command. A conditional command may be conditioned upon whether a data version identifier or a metadata version identifier equals a particular value. A conditional command execution engine retrieves the relevant version identifier from a version-specific metadata record, and performs a check on whether the condition is satisfied. If the condition is satisfied, the engine ensures that the version-specific record has not been modified during the check, and updates metadata to reflect execution of the conditional command.”

Oracle International Corporation, Redwood Shores, CA, has been assigned a patent (10,831,666) developed by Shi, Jia, Campbell, CA, Zhang, Wei, Foster City, CA, Nagarajan, Vijayakrishnan, Redwood City, CA, Huang, Shih-Yu, Mountain View, CA, and Umamageswaran, Kothanda, Sunnyvale, CA, for a “secondary storage server caching.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Techniques related to failover to the secondary storage server from a primary storage server of a database server without degrading the performance of servicing storage requests for client applications are provided. In an embodiment, the secondary storage server receives, from the database server, an eviction notification indicating that a set of data blocks has been evicted from a cache. The secondary storage server’s memory hierarchy includes a secondary cache and a secondary persistent storage that stores a second copy of the set of data blocks. The secondary storage server persistently stores a copy of data, which is also persistently stored on the primary storage server, which includes a first copy of the set of data blocks. In an embodiment, upon receiving the eviction notification, the secondary storage server retrieves the second copy of the set of data blocks from the secondary persistent storage of the secondary storage server and loads the second copy of the set of data blocks into the secondary cache. After an interruption event, the secondary storage receives a request for a subset of the set of data blocks based on a request for data, at the database server. Upon receiving the request for the subset of the set of data blocks, the second storage server retrieves the subset of the set of data blocks from the second copy of the set of data blocks stored on the secondary cache of the secondary storage server without retrieving any of such data blocks from the second copy of the set of data blocks stored on the persistent storage of the secondary storage server. The second storage server sends the subset of the set of data blocks to the database server.”
