Patent number: 11341159Abstract: In-stream data load in a replication environment includes extracting source data from a source data store that is in a replication relationship with a target data store. A replication facility replicates to a target system changes made to the source data store. The replication facility includes a replication engine that reads a replication log into which the replication facility records the changes and sends the changes to the target system for application to the target data store. The extracting is performed by an extract utility separate from the replication engine. The in-stream data load also includes injecting, by the extract utility, the extracted source data into the replication log in-line with the changes recorded in the replication log by the replication facility and according to a format such that the replication engine can read and send the source data to the target system.Type: GrantFiled: August 22, 2019Date of Patent: May 24, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Austin Willoughby, Gregg Andrew Upton, Paul M.

Patent number: 11176118Abstract: Provided are a computer program product, system, and method for performing conflict analysis of replicated changes among nodes in a network A first node and a second node include a first instance and second instance of a data set, respectively. The second node receives a first transaction replicated from the first node, applied to the first instance of the data set. The second node determines a conflict that would occur between the replicated first transaction and a second transaction applied to the second instance of the data set. A conflict policy is applied at the second node to perform a first action in response to determining the conflict. The conflict policy is applied to the first node to perform a second action at the first node to handle the conflict when the first node receives a replication of the second transaction to the second instance of the data set.Type: GrantFiled: May 30, 2019Date of Patent: November 16, 2021Assignee: International Business Machines CorporationInventors: Paul M.

Patent number: 11030216Abstract: A mechanism is provided for replicating non-supported data types using an existing replication format supported by an existing replication system. Responsive to detecting an application writing data to a local storage that is to be replicated to the secondary site, the input/output (I/O) operation being performed by the application is intercepted. Data of the I/O operation in a non-supported format is converted to a format supported by the existing replication system. A replication log record is generated for the data in the format supported by the existing replication system. The data described by the replication log record for the data is then stored in a storage device at the secondary site.Type: GrantFiled: January 8, 2018Date of Patent: June 8, 2021Assignee: International Business Machines CorporationInventors: Paul M.
