Abstract: 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.

Abstract: In one aspect, the present approach provides functionality to allow a customer to rename a client instance utilized by the customer without having to provision a new instance. In such an implementation, data may be kept or maintained within the renamed instance. In a further aspect, a virtual internet protocol (VIP) address may be migrated to address load conditions. In accordance with aspects of the approach, multiple VIPs and the instances using the VIPs may be migrated at one time and without downtime to the customer.

Abstract: A mobile power source includes an upper cover, a charging battery, a circuit board, a group of charging input metal contacts and a lower cover. The upper cover and lower cover match to form a mobile power source case, and the charging battery and group of charging input metal contacts are respectively electrically connected to the circuit board. The charging battery and circuit board are accommodated in the mobile power source case, and the group of charging input metal contacts are exposed outside of the mobile power source case.

Abstract: In a distributed computing system, cloning operations determine when each of multiple backup database instances most recently experienced an update. If a most recently updated backup database instance was updated within a prescribed time period of one or more other backup database instances, a source instance for cloning is deemed to be one of these database instances satisfying a prescribed proximity criteria relative to a designated database instance. If a difference in update times is greater than the prescribed time period for the two most recent backup database instances, the source instance for cloning is deemed to be the most recently updated backup database instance. The control center conducts cloning to a target instance using the selected backup database instance as a source instance.
