Patent number: 11652892Abstract: Disclosed is a method, a computer program product, and a computer system for implementing automatic connection load balancing of database connections between instances of a cluster. Load imbalances are detected globally in the cluster, and can be corrected autonomously by the local instances. The local controller/orchestrator detects the imbalance, computes a target for the instance, and makes any necessary adjustments on the instance, where a server marks the connections to redistribute, and then implements draining and/or planned failover to move sessions.Type: GrantFiled: September 30, 2020Date of Patent: May 16, 2023Assignee: Oracle International CorporationInventors: Chandrajith Ramachandran Unnithan, Michael Ullrich Zoll, Wai Shun Wilson Chan, Tak Fung Wang, Carol Lyndall Colrain, Troy Anthony

Patent number: 10585881Abstract: A method and apparatus is provided for dynamically generating data to dataset mappings and dataset to logical instance mappings and distributing these mappings to subscribers for the purpose of routing work. An advisory engine updates the mappings of data to data sets based at least in part on changing demands and patterns of access to data, and updates the mappings of datasets to logical instances based at least in part on anticipated capacity and change in conditions of the database servers. The subscribers receive and store the mapping information that maps the data to dataset identifiers, and dataset identifiers to logical database instances. The subscribers may also receive information that describes the current availability conditions of database instances, which are used to override the mapping of logical database instances to physical database instances. Subscribers may use the data to dataset mapping to map data identified from in an incoming database request to a dataset.Type: GrantFiled: January 7, 2016Date of Patent: March 10, 2020Assignee: Oracle International CorporationInventors: Carol Lyndall Colrain, Michael Ullrich Zoll, Vladimir Begun, Rajkumar Arockia Irudayaraj, Logan O'Sullivan Bruns

Patent number: 9242317Abstract: A method for producing piston for an internal combustion engine which has a piston head that has a circumferential cooling channel as well as a combustion bowl having a circumferential bowl wall that makes a transition into a piston crown by way of a bowl edge region. The combustion bowl is formed at least in part by a piston base body and the bowl wall is formed at least in part from an insert. The insert is connected with the piston base body by means of beam welding. A lower weld seam is configured in the bowl wall, which seam encloses an acute angle with the piston center axis (M) and ends in the lower half of the cooling channel. An upper weld seam runs from the cooling channel ceiling to the piston crown and is disposed centered or radially offset toward the outside, with reference to the clear width of the cooling channel.Type: GrantFiled: January 24, 2014Date of Patent: January 26, 2016Assignee: MAHLE International GmbHInventors: Rainer Scharp, Peter Kemnitz, Michael Ullrich
