摘要： When multiple backup database instances most recently experienced an update is determined. If a most recently updated backup database instance was updated within a defined time period of one or more other backup database instances, a source instance for cloning is selected as the backup database instance that satisfies at least one of a physical or logical proximity criteria relative to a designated database instance. If a difference in update times is greater than the defined time period, e.g., for the two most recent backup database instances, the source instance for cloning is selected to be the most recently updated backup database instance. Cloning to a target instance is performed using the selected backup database instance as a source instance as long as preparatory operations all pass. If not, the source databases are used for the cloning while still being accessible to clients.

摘要： Disclosed are methods, apparatuses and systems for collecting transactional and dimensional data. One implementation includes a configuration management database, a first data collection agent operating on a first monitored server to collect metadata associated with the first monitored server from the configuration management database using the first data collection agent, collect metric data from the first monitored server regarding operation of the first monitored server, wherein the metric data includes at least one metric collected from at least one application executing on the first monitored server; and assemble the collected metric data and at least part of the collected metadata into a packet for transmission from the first monitored server to a message bus; and a distributed database configured to receive the packet from the message bus and to store the collected metric data and metadata included in the packet.

摘要： Implementations of a system, method and apparatus described herein execute a discovery process to identify a plurality of computing devices within a computer network and a respective configuration associated with each of the plurality of computing devices. Upon discovery of a first computing device configured by an agent, configuration management of the computer network is searched for a definition used by the agent to configure the first computing device, and the discovery process for the first computing device is modified based on the definition to identify a first plurality of configuration items associated with a current configuration of the first computing device. Finally, a service model database is updated with the first plurality of configuration items.

摘要： A failure resistant distributed computing system includes primary and secondary datacenters each comprising a plurality of computerized servers. A control center selects orchestrations from a predefined list and transmits the orchestrations to the datacenters. Transmitted orchestrations include less than all machine-readable actions necessary to execute the orchestrations. The datacenters execute each received orchestration by referencing a full set of actions corresponding to the received orchestration as previously stored or programmed into the computerized server and executing the referenced full set of actions. At least one of the orchestrations comprises a failover operation from the primary datacenter to the secondary datacenter. Failover shifts performance of task from a set of processing nodes of the primary datacenter to a set of processing nodes of the secondary datacenter, such tasks including managing storage accessible by one or more remote clients and running programs on behalf of remote clients.

摘要： Implementations of a system, method and apparatus described herein receive, for a configuration item in a configuration management database, status indicating an operational state and an automation state associated with the configuration item, and determine whether a conflict will occur with at least one of the operational state or the automation state of the configuration item as a result of a process affecting the configuration item. When the conflict will not occur, a change is made to at least one of the operational state or the automation state of the configuration item in accordance with the process. Upon a conclusion of the process, the change is removed. If the conflict will occur, the process not allowed to continue.
