Publication number: 20160283328Abstract: A snapshot of selected objects in a source repository is created in response to the user-initiated replication. The snapshot is designated as a snapshot replication job. Unsynchronized objects in a target destination are detected by comparing a state of the selected objects in the snapshot with a current state of the target destination at the time of execution of the snapshot replication job. One of the selected objects is retrieved in an ordered manner from the snapshot. An object identification (ID) and a state ID are sent to the target destination and used to locate and compare the selected object with a current state of the selected object in the target destination.Type: ApplicationFiled: June 7, 2016Publication date: September 29, 2016Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay AKIRAV, Yariv BACHAR, Ron EDELSTEIN, Asaf LEVY, Oded SONIN

Patent number: 9430542Abstract: A snapshot of selected objects in a source repository is created in response to the user-initiated replication. The snapshot is designated as a snapshot replication job. The snapshot replication job is added to the end of a replication queue to await execution for the synchronized object replication. Unsynchronized objects in a target destination are detected by comparing a state of the selected objects in the snapshot with a current state of the target destination at the time of execution of the snapshot replication job. The unsynchronized objects in the target destination are synchronized based upon the comparison of the state of the selected objects in the snapshot with the current state of the target destination at the time of execution of the snapshot replication job.Type: GrantFiled: June 5, 2012Date of Patent: August 30, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Shay Akirav, Yariv Bachar, Ron Edelstein, Asaf Levy, Oded Sonin

Patent number: 9396027Abstract: For resource allocation of resources for a dual activity system, each of the dual activities may be started at a static quota and is allocated its respective static quota of resources, and determining which of the dual activities is a demanding dual activity. The resource boundary may be increased for a resource request for at least one of the dual activities until a resource request for an alternative one of the at least one of the dual activities is rejected. A reduced actual resource boundary for the demanding dual activity based on a multiplicative decrease of the dual activity's actual resource boundary is calculated, and the resource boundary for the at least one of the dual activities may be reduced, and a wait after decrease mode may be commenced until a current resource usage is one of less than and equal to the reduced resource boundary.Type: GrantFiled: February 26, 2014Date of Patent: July 19, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yariv Bachar, Ron Edelstein, Oded Sonin

Publication number: 20160203161Abstract: A unique file-system node identification (ID) is created for each newly created node in a file system repository by combining a grid identification (ID), a repository identification (ID), and a node identification (ID) to form the unique file-system node ID. The unique file-system node ID is associated with a unique association identification (ID) thereby linking the node from a source repository to a target repository to form an association when performing a replication operation between the source repository and the target repository. Upon removing the association, the unique association ID is unlinked from a replication policy in a source repository, where an initiated replication operation is disabled.Type: ApplicationFiled: March 22, 2016Publication date: July 14, 2016Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yariv BACHAR, Aviv CARO, Asaf LEVY, Oded SONIN

Patent number: 9305004Abstract: A unique file-system node identification (ID) is created for each newly created node in a file system repository by combining a grid identification (ID), a repository identification (ID), and a node identification (ID) to form the unique file-system node ID. The unique file-system node ID is associated with a unique association identification (ID) for creating an association for linking the node from a source repository to a target repository when performing a replication operation between a repository and another repository. The different replication instances of the node in the file system repository are distinguished by the unique association ID assigned to each of the replication instances.Type: GrantFiled: June 5, 2012Date of Patent: April 5, 2016Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yariv Bachar, Aviv Caro, Asaf Levy, Oded Sonin
