Abstract: A database storage system provides replication capability that allows data from a source database and application specific data from a source application to be replicated respectively to a target database storage system and a target application, thereby creating a virtual database and a virtual application. The database storage system generates a plurality of snapshots of the virtual database at a corresponding plurality of time points and a plurality of snapshots of the virtual application at the corresponding plurality of time points. The database storage system associates the plurality of snapshots of the virtual database with the plurality of snapshots of the virtual application at the corresponding plurality of time points so as to generate a historical time-sequence of concurrent modifications to both the virtual database and the virtual application at the one or more development environments, thereby allowing concurrent read/write and rollback, of data and applications.

Abstract: Allocation of resources across multiple consumers allows efficient utilization of shared resources. Observed usages of resources by consumers over time intervals are used to determine a total throughput of resources by the consumers. The total throughput of resources is used to determine allocation of resources for a subsequent time interval. The consumers are associated with priorities used to determine their allocations. Minimum and maximum resource guarantees may be associated with consumers. The resource allocation aims to allocate resources based on the priorities of the consumers while aiming to avoid starvation by any consumer. The resource allocation allows efficient usage of network resources in a database storage system storing multiple virtual databases.

Abstract translation: 跨多个消费者分配资源可以有效利用共享资源。 消费者随时间间隔观察资源的用途，用于确定消费者的资源总量。 资源的总吞吐量用于确定后续时间间隔内资源的分配。 消费者与确定其分配的优先级相关联。 最低和最高的资源保证可能与消费者有关。 资源分配旨在根据消费者的优先事项分配资源，同时旨在避免任何消费者的饥饿。 资源分配允许在存储多个虚拟数据库的数据库存储系统中有效地使用网络资源。

Abstract: An application development system allows developers of a software system to manage infrastructure resources during the development and testing process. The application development system allows users to define application containers that comprise components including source code, binaries, and virtual databases used for the application. An application container can be associated with policies that control various aspects of the actions taken using the application container including constraints and access control. The application development system enforces the policies for actions taken by users for the application containers. The encapsulation of policies with the application containers allows users of the application containers to take actions including creating virtual databases, provisioning virtual databases, and the like without requiring system administrators to manage resource issues.

Abstract: Virtual databases are provisioned using point-in-time copies of a source database. Transaction logs received from the source database are applied to a point-in-time copy of the source database to create recovery milestones comprising database blocks that can be used to provision virtual databases. The recovery milestones are created in advance of receiving a request to provision a virtual database. Each recovery milestone is validated to determine that a consistent database snapshot can be created using the recovery milestone. If a problem is identified that prevents creation of a consistent database snapshot, the problem is fixed before creating the next recovery milestone. In response to receiving a request to provision a virtual database corresponding to a point in time, a recovery milestone is identified and transaction logs applied to the recovery milestone to create a database snapshot corresponding to the requested point in time.

Abstract: Information from multiple databases is retrieved and stored on a database storage system. Multiple point-in-time copies are obtained for each database. A point-in-time copy retrieves data changed in the database since the retrieval of a previous point-in-time copy. A virtual database (VDB) is created by creating a set of files in the data storage system. Each file in the set of files created for a VDB is linked to the database blocks on the database storage system associated with a point-in-time copy of the source database. The set of files associated with the VDB are mounted on a database server allowing the database server to read from and write to the set of files. Workflows based on VDBs allow various usage scenarios based on databases to be implemented efficiently, for example, testing and development, backup and recovery, and data warehouse building.

Abstract: File system backups are performed by copying information describing changes in the file system since a previous point in time. To restore data, a virtual restored file system (VRFS) structure is created corresponding to a snapshot of data copied from the file system that is stored in the backup file system. A client can read the data stored in the backup file system pointed at by the VRFS structure as well as write to the backup file system. Multiple clients can share blocks of data stored on the backup file system via the same VRFS structure or via multiple VRFS structures. If a client writes to a data block pointed at by a VRFS, a copy of the data block is made to which the client makes changes so that the data in the original data blocks is saved for other clients.

Abstract: A storage system maintains copies of a source database to allow virtual databases to be provisioned. Transaction logs received from the source database are applied to database blocks stored in the storage system to update the database blocks. The storage system checks if there are defect in the transaction logs of the source database. If a defect in transaction logs is detected, the storage system obtains a latest copy of the source database. The storage system matches database blocks of the received copy with database blocks already available in the storage system to determine whether a corresponding database block is already available in the storage system. If a received database block is different from database blocks already available at the storage system, the received database block is stored in the storage system. The database blocks may be matched using a hash value of the database blocks.
