20110060939 | HIGH AVAILABILITY VIA DATA SERVICES - Application-level replication, the synchronization of data updates within a cluster of application servers, may be provided by having application servers themselves synchronize all updates to multiple redundant databases, precluding the need for database-level replication. This may be accomplished by first sending a set of database modifications requested by the transaction to a first database. Then a message may be placed in one or more message queues, the message indicating the objects inserted, updated, or deleted in the transaction. Then a commit command may be sent to the first database. The set of database modifications and a commit command may then be sent to a second database. This allows for transparent synchronization of the databases and quick recovery from a database failure, while imposing little performance or network overhead. | 03-10-2011 |
20110173489 | CONTROL METHOD FOR PROTECTING FAILURE RECOVERY OF ETHERNET RING AND ETHERNET RING NODES - The present invention discloses a method for controlling failure recovery of Ethernet loop protection and an Ethernet loop node. The method comprises: when a node adjacent to a failed link detects recovery of the link, blocking a port just recovered, setting the port to be in a pre-forwarding state and starting a timer, and releasing the port temporarily blocked if the node adjacent to the failed link has not received a control protocol message sent by a master node during a timing period of the timer, and transferring the port from the pre-forwarding state to a forwarding state. The present invention allows a port of a node adjacent to a recovered link to enter into a forwarding state from the pre-forwarding state as early as possible on the premise that a corresponding control protocol message is unable to be received in time. | 07-14-2011 |

20150301880 | PROVIDING BOOT DATA IN A CLUSTER NETWORK ENVIRONMENT - A computer cluster includes a group of connected computers that work together essentially as a single system. Each computer in the cluster is called a node. Each node has a boot device configured to load an image of an operating system into the node's main memory. Sometimes the boot device of a first node experiences a problem that prevents the operating system from loading. This can affect the entire cluster. Some aspects of the disclosure, however, are directed to operations that determine the problem with the first node's boot device based on a communication sent via a first communications network. Further, the operations can communicate to the first node a copy of boot data from a second node's boot device. The copy of the boot data is sent via a second communications network different from the first communications network. The copy of the boot data can solve the first boot device's problem. | 10-22-2015 |

The switch includes one or more ports, a persistent storage module, a restoration module, and a retrieval module. The persistent storage module stores configuration information associated with the switch in a data structure, which includes one or more columns for attribute values of the configuration information, in a local persistent storage. The restoration module instantiates a restoration database instance in the persistent storage from an image of the persistent storage. The retrieval module retrieves attribute values from a data structure in a current database instance and the restoration database instance in the persistent storage. The restoration module then applies the differences between attribute values of the restoration database instance and the current database instance in the persistent storage to switch modules of the switch, and operates the restoration database instance as the current database instance in the persistent storage. | 06-30-2016 |
