Patent number: 8549168Abstract: A method includes receiving active application messages that are part of an active message stream in a subscribing client device from an active feed adapter. Each active application message is characterized by an active source stream identifier, an active source stream sequence number, and an active message sequence number. The method includes receiving, in response to a failover from the active feed adapter to a backup feed adapter, backup application messages in the subscribing client device from the backup feed adapter. Each backup application message is characterized by a backup source stream identifier, a backup source stream sequence number, and a backup message sequence number. The method includes administering, by the subscribing client device, the backup application messages in dependence upon the active stream source identifier, the active stream source sequence number, the backup stream source identifier, and the backup stream source sequence number.Type: GrantFiled: January 4, 2012Date of Patent: October 1, 2013Assignee: International Business Machines CorporationInventors: Kenneth W.

Patent number: 8428065Abstract: A group communication service maintains synchronization limiting the group to the processing entities that receive a plurality of source message streams from sources outside the group and transmit delivery message streams to destinations that are outside the group. Synchronization of message ordering and other state synchronization directives are communicated from a leader exclusively to other group members. Once having declared themselves to be synchronized and active by a reply protocol message, which is an opaque object and is interpreted by an application layer, the processing entities independently process the source message streams in accordance with the order specified in the directives, without requiring additional sequencing information from another processing entity.Type: GrantFiled: June 18, 2007Date of Patent: April 23, 2013Assignee: International Business Machines CorporationInventors: Eliezer Dekel, Gidon Gershinsky, Avraham Harpaz, Alexander Krits, Benjamin Mandler, Nir Naaman, Idan Zach

Patent number: 8285924Abstract: A cache control system is disclosed for use with data storage apparatus having a movably mounted storage element, such as a magnetic or optical disk and solid-state cache memory, in which the storage element is not at operating speed when data access has not occurred during a predetermined time period, comprising means arranged to access data stored on the storage element if a read or write request cannot be satisfied via access to the cache memory and a cache replacement mechanism for transferring data between the cache memory and the storage element to maintain consistency of data therebetween. The system is characterized in that the cache replacement mechanism performs data transfers between the cache memory and the storage element only while the storage element is at operating speed after a read or write request has given rise to an access to the storage element.Type: GrantFiled: December 27, 1994Date of Patent: October 9, 2012Inventors: Oded Cohn, Eliezer Dekel, Michael Rodeh
