    Abstract: Replicated instances in a database environment provide for automatic failover and recovery. A monitoring component can obtain a lease enabling the component to periodically communicate with, and monitor, one or more data instances in the data environment, where the data instance can be a replicated instance including a primary and a secondary replica. For a large number of instances, the data environment can be partitioned such that each monitoring component can be assigned a partition of the workload. In the event of a failure of a monitoring component, the instances can be repartitioned and the remaining monitoring components can be assigned to the new partitions to substantially evenly distribute the workload.

    Abstract: The present invention relates to a switching center server comprising: -a blade cluster with a plurality of blades (110), -a plurality of pooled resources accessible by said plurality of blades (110) for handling a call, and -a master (112) provided on one of the blades centrally coordinating the usage of the pooled resources, the master as a central instance being responsible for allocation, de-allocation and maintenance of the pooled resources. At outage of one or more blades, the invention provides mechanisms to keep impacts on ongoing calls to a minimum and to keep pooled resources available to the remaining blades.

    Abstract: In a computing device supporting a failover in an event stream processing (ESP) system, an event block object is received. A first status of the computing device as active or standby is determined. When the first status is active, a second status of the computing device as newly active or not newly active is determined. Newly active is determined when the computing device is switched from a standby to an active status. When the second status is newly active, a last published event block object identifier that uniquely identifies a last published event block object is determined. A next event block object is selected from a non-transitory computer-readable medium accessible by the computing device. The next event block object has an event block object identifier that is greater than the determined last published event block object identifier. The selected next event block object is published to an out-messaging network device.
