Abstract: A method for switching over a virtual application two-node cluster in a cloud environment, including: sending an association state of a shared EBS volume to the standby virtual machine; receiving a request for removing an association between the active virtual machine and the shared EBS volume; removing the association between the active virtual machine and the shared EBS volume; receiving a request for associating the shared EBS volume sent by the standby virtual machine; and associating the standby virtual machine with the shared EBS volume. A brain-split problem can be completely solved using the method and an apparatus disclosed in the embodiments of the present invention. In addition, dependence on a reference active node is no longer required, which can simplify deployment of an application two-node cluster and improve reliability of the application two-node cluster.

Abstract: Jobs submitted to a primary location of a service within a period of time before and/or after a fail-over event are determined and are resubmitted to a secondary location of the service. For example, jobs that are submitted fifteen minutes before the fail-over event and jobs that are submitted to the primary network before the fail-over to the second location is completed are resubmitted at the secondary location. After the fail-over event occurs, the jobs are updated with the secondary network that is taking the place of the primary location of the service. A mapping of job input parameters (e.g. identifiers and/or secrets) from the primary location to the secondary location are used by the jobs when they are resubmitted to the secondary location. Each job determines what changes are to be made to the job request based on the job being resubmitted.

Abstract: An embodiment of the invention is associated with a virtualized environment that includes a hypervisor, client LPARs, and virtual servers that each has a SEA, wherein one SEA is selected to be primary SEA for connecting an LPAR and specified physical resources. A first SEA of a virtual server sends a call to the hypervisor, and in response the hypervisor enters physical adapter capability information, contained in the call and pertaining to the first SEA, into a table. Further in response to receiving the call, the hypervisor decides whether or not the first SEA of the virtual server should then be the primary SEA. The hypervisor sends a return call indicating its decision to the first SEA.

Abstract: A method for network controller initialization that includes identifying a controller connected to a network as a primary controller that manages switches in the network. One or more other controllers connected to the network are identified as secondary controllers. A failover priority table is created. The failover table indicates an order that the one or more other controllers will replace the controller as the primary controller in the event that the controller enters a failure mode. The failover priority table is broadcast to the switches in the network.
