Abstract: A plurality of storage subsystems and a plurality of storage devices are maintained, and wherein each storage subsystem includes at least one storage device of the plurality of storage devices. A plurality of storage groups is generated, wherein each storage group includes one or more storage devices selected from the plurality of storage devices, and wherein the one or more storage devices selected in each storage group are included in at least two different storage subsystems. The plurality of storage groups is adjusted based on: (a) usage statistics of the data, wherein the usage statistics are stored in a log file; and (b) properties and organization of the data stored in a plurality of data structures.

Abstract: A method, system, and computer program product for implementing Serviceability Level Indicator Processing (SLIPs) for storage alterations in a computer system is provided. A plurality of storage release requests is analyzed to identify an address monitored by a storage alteration slip. Upon identification of the address, the storage alteration slip is disabled and an initialization slip is re-enabled.

Abstract: A method, system and computer-readable medium for emulating an application in a non-production computer system are presented. In a preferred embodiment, the method includes the steps of: receiving a first input that selects an application from all applications on a production computer system; receiving a second input that selects specific control files and data files that are to be utilized in an emulated version of a selected application on a non-production computer system; migrating a copy of instructions file from the selected application from the production computer system to the non-production computer system; migrating a copy of the specific control files and data files from the production computer system to the non-production computer system; and executing the copy of instructions files, while using the copy of the specific control files and data files, in the non-production computer system.
