Abstract: A computer system for mounting a replica of a database. The computer system includes a first instance of a database operating in a first environment. The first instance has allocated to it a first amount of a resource. A replica of this first instance is created and a second instance of the database is created from this replica. The second instance is created in a second environment and has allocated to it a second amount of the resource. The second amount of the resource is different from the first amount of the resource.

Abstract: A computer system for mounting a replica of a database. The computer system includes a replica of a first instance of a database and is operated to create from that replica a second instance of the database. In response to a request to create the second instance, the system automatically accesses the replica. The replica has a parameter that specifies allocation of a first resource to the first instance of the database, which has a first value for the first instance. The second instance is mounted using at least a portion of the replica, but a second value for the parameter, giving the parameter a value different from the first value when the second instance is automatically mounted.
