Patent number: 11971869Abstract: A shared-nothing database system is provided in which parallelism and workload balancing are increased by assigning the rows of each table to “slices”, and storing multiple copies (“duplicas”) of each slice across the persistent storage of multiple nodes of the shared-nothing database system. When the data for a table is distributed among the nodes of a shared-nothing system in this manner, requests to read data from a particular row of the table may be handled by any node that stores a duplica of the slice to which the row is assigned. For each slice, a single duplica of the slice is designated as the “primary duplica”. All DML operations (e.g. inserts, deletes, updates, etc.) that target a particular row of the table are performed by the node that has the primary duplica of the slice to which the particular row is assigned. The changes made by the DML operations are then propagated from the primary duplica to the other duplicas (“secondary duplicas”) of the same slice.Type: GrantFiled: October 26, 2022Date of Patent: April 30, 2024Assignee: Oracle International CorporationInventors: Jesse Kamp, Allison L.

Patent number: 11966356Abstract: Systems and methods for reducing latency of probing operations of remotely located linear hash tables are described herein. In an embodiment, a system receives a request to perform a probing operation on a remotely located linear hash table based on a key value. Prior to performing the probing operation, the system dynamically predicts a number of slots for a single read of the linear hash table to minimize total cost for an average probing operation. The system determines a hash value based on the key value and determines a slot of the linear hash table to which the hash value corresponds. After predicting the number of slots, the system issues an RDMA request to perform a read of the predicted number of slots from the linear hash table starting at the slot to which the hash value corresponds.Type: GrantFiled: December 23, 2022Date of Patent: April 23, 2024Assignee: Oracle International CorporationInventors: Tinggang Wang, Shuo Yang, Hideaki Kimura, Garret F.

Publication number: 20240003959Abstract: In an insulation inspection method for detecting creeping discharge that occurs in a coil in an armature, a predetermined impulse voltage is applied to the coil, and an electrical current value of a current that flows to a current detector that is connected to the coil is detected. The detected electrical current value is analyzed to acquire a relationship between a frequency and an electrical current value spectrum in the detected electrical current value. Based on the acquired relationship, a total sum of electrical current value spectrum areas in a high-frequency band is calculated as a high-frequency spectrum area. The high-frequency band differs from a predetermined low-frequency band in which partial discharge that occurs in a portion of a thin coating of the wire configuring the coil can be detected. Based on a magnitude of the calculated high-frequency spectrum area, creeping discharge that occurs in the coil is detected.Type: ApplicationFiled: June 27, 2023Publication date: January 4, 2024Applicants: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN CORPORATIONInventors: Yuki KOSAKA, Hideyuki SATOU, Hideaki KIMURA

Patent number: 11709784Abstract: Techniques are described for offloading remote direct memory operations (RDMOs) to “execution candidates”. The execution candidates may be any hardware capable of performing the offloaded operation. Thus, the execution candidates may be network interface controllers, specialized co-processors, FPGAs, etc. The execution candidates may be on a machine that is remote from the processor that is offloading the operation, or may be on the same machine as the processor that is offloading the operation. Details for certain specific RDMOs, which are particularly useful in online transaction processing (OLTP) and hybrid transactional/analytical (HTAP) workloads, are provided.Type: GrantFiled: March 26, 2021Date of Patent: July 25, 2023Assignee: Oracle International CorporationInventors: Hideaki Kimura, Garret F.

Publication number: 20230179509Abstract: In the flush of an FDB, as the number of user bases increases, more SWs are required to flush, and an influence on another user also increases due to flooding. The lapse of an aging time causes long-time communication interruption depending on network specifications and apparatus settings. In order to complete transmission of a user frame from the base after an accommodation change, it is necessary not only to do work of a communication carrier side but also to enter a user base. The present disclosure is a communication apparatus including a signal reception unit that receives a signal, a signal transmission unit that transmits a signal, and a frame generation unit that generates a control frame for updating a forwarding database (FDB) of a relay network on the basis of FDBs of apparatuses connected to the relay network. The signal transmission unit transmits the control frame generated by the frame generation unit to each of the apparatuses connected to the relay network.Type: ApplicationFiled: May 22, 2020Publication date: June 8, 2023Applicant: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yuhei KAWAKAMI, Hideaki KIMURA, Akihiro MORITA
