Data replication conflict detection and resolution for a multi-tenant identity cloud service
Oracle International Corporation, Redwood Shore, CA, has been assigned a patent (11,165,634) developed by Medam, Venkateswara Reddy, Modesto, CA, Ho, Fannie, Shih, Kuang-Yu, Fremont, CA, Balu, Balakumar, Dublin, CA, and Srinivasan, Sudhir Kumar, San Jose, CA, for “data replication conflict detection and resolution for a multi-tenant identity cloud service.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Embodiments include a multi-tenant cloud system with a first data center and a second remote data center. The first data center authenticates a first client and stores resources that correspond to the first client, and is in communication with the second data center. The second data center authenticates the first client and replicates the resources. The first data center receives a write request for the first client, writes the write request and generates change event messages in a first order. The first data center pushes the change event messages to the second data center via REST API calls. In response to receiving the change event messages, the second data center is configured to write the change event messages in the first order to its local database.”

The patent application was filed on August 22, 2018 (16/108,315).

Consistently enforcing I/O resource constraints for workloads on parallel-access storage
Oracle International Corporation, Redwood Shore, CA, has been assigned a patent (11,132,131) developed by Kumar, Kishy, Redwood City, CA, Shah, Akshay, and Umamageswaran, Kothanda, Sunnyvale, CA, for “consistently enforcing I/O resource constraints for workloads on parallel-access storage devices.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “The techniques described herein limit client utilization of a parallel-access storage device. Specifically, client utilization of a particular storage device is estimated using I/O cost metrics to estimate the costs of I/O requests from the client to the particular storage device. The I/O cost metrics are determined based on calibration-based system performance data, which represents a system-wide measure of storage device performance for a system in which the particular storage device resides. The calibration-based system performance data includes one or both of composite throughput data and composite IOPS data for multiple parallel-access devices in the system. The cost estimates for I/O requests issued from a client to a parallel-access device are tracked in a total cost estimate for the client. Client utilization of the storage device, as tracked by the total cost estimate for the client, is limited to a percentage of the total estimated bandwidth of the storage device.”

The patent application was filed on December 30, 2019 (16/730,608).

Storing derived summaries on persistent memory of storage device
Oracle International Corporation, Redwood Shore, CA, has been assigned a patent (11,086,876) developed by Meiyyappan, Krishnan, Fremont, CA, Ustimenko, Semen, Sunnyvale, CA, Ng, Adrian Tsz Him, Redwood City, CA, and Umamageswaran, Kothanda, Sunnyvale, CA, for “storing derived summaries on persistent memory of a storage device.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Region summaries of database data are stored in persistent memory of a storage cell. Because the region summaries are stored in persistent memory, when a storage cell is powered off and data in volatile memory is not retained, region summaries are nevertheless preserved in persistent memory. When the storage cell comes online, the region summaries already exist and may be used without the delay attendant to regenerating the region summaries stored in volatile memory.”

The patent application was filed on September 29, 2017 (15/721,328).

Efficient incremental backup and restoration of file system hierarchies with cloud object storage
Oracle International Corporation, Redwood Shore, CA, has been assigned a patent (11,074,221) developed by Maybee, Mark, Boulder, CO, Kremer, James, Longmont, CO, and Gibson, Gavin, Westminster, CO, for “efficient incremental backup and restoration of file system hierarchies with cloud object storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface. In certain embodiments, file system functionality may be layered on cloud object interfaces to provide cloud-based storage while allowing for functionality expected from a legacy applications. For instance, POSIX interfaces and semantics may be layered on cloud-based storage, while providing access to data in a manner consistent with file-based access with data organization in name hierarchies. Various embodiments also may provide for memory mapping of data so that memory map changes are reflected in persistent storage while ensuring consistency between memory map changes and writes. For example, by transforming a file system disk-based storage into cloud-based storage, the file system gains the elastic nature of cloud storage.”

The patent application was filed on September 12, 2019 (16/568,672).

Consistent file system semantics with cloud object storage
Oracle International Corporation, Redwood Shore, CA, has been assigned a patent (11,074,220) developed by Maybee, Mark, Boulder, CO, Kremer, James, Longmont, CO, and Latushkin, Victor, Superior, CO, for “consistent file system semantics with cloud object storage.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Techniques described herein relate to systems and methods of data storage, and more particularly to providing layering of file system functionality on an object interface.

Automatic disaster recovery mechanism for file-based version control system using lightweight backups
Oracle International Corporation, Redwood Shore, CA, has been assigned a patent (11,068,352) developed by Lopez, Jonathan Lopez, San Mateo, CA, and Vimberg, Juan Ignacio, Foster City, CA, for an “automatic disaster recovery mechanism for file-based version control system using lightweight backups.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “In one implementation, lightweight incremental backups are created by a data recovery tool, which provides an extra layer of protection against data loss, and also provides a way of moving repositories between databases without the need of copying each of the repositories. Implementations include backing up a distributed cluster of services providing a simple, safe, and convenient way of instantiating files system repositories in a database, thereby avoiding the performance and scalability issues of using a database repository itself. In other implementations, a lightweight backup object is created that includes a threshold amount of compressed information. The lightweight backup objects may be configured to provide the differences between revisions, and/or may be configured to replicate or rebuild the repository from scratch. Implementations may be configured to backup and restore any single or revision set in any repository state either online or offline.”

The patent application was filed on February 16, 2017 (15/434,475).

Replication of resource type and schema metadata for a multi-tenant identity cloud service

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Embodiments operate a multi-tenant cloud system with a first data center. At the first data center, embodiments authenticate a first client and store resources that correspond to the first client, the first data center in communication with a second data center that is configured to authenticate the first client and replicate the resources. In response to upgrading global resources at the first data center to a new version, embodiments generate a manifest file including a listing of global resource types and schemas that are modified or added in response to the upgrading. Embodiments further upgrade global resources based on the manifest file and write the upgraded global resources to a first global database and generate change event messages corresponding to the upgraded global resources.”

The patent application was filed on June 27, 2019 (16/454,483).

Write protecting portions of magnetic tape storage media
Oracle International Corporation, Redwood Shore, CA, has been assigned a patent (11,056,144) developed by Hostetter, David G., Louisville, CO, and Herron, John Steven, Arvada, CO, for “system and method for write protecting portions of magnetic tape storage media.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A non-transitory computer readable storage medium includes a tape having a plurality of partitions configured for storing data, and a plurality of read-only partition identifiers, each read-only partition identifier associated with one of the plurality of partitions and readable by a tape drive having a processor and memory for writing and reading tape data. Each read-only partition identifier selectively designates a corresponding one of the partitions as read-only to prevent data from being written to the designated read-only partition by the tape drive.”
