Abstract: A method which prioritizes the subgroups in a consistency group by usage and/or business process. Thereafter, in case of abnormal operation of the process for copying the consistency group from primary storage to secondary storage, only a portion of the subgroups of the consistency group are copied from primary storage to secondary storage.

Abstract: A method is provided for facilitating data replication in a storage system. A logical volume of a first storage array of a replicated pair is preconfigured with one or more logical volume attributes, which include a compressible configuration bit that indicates whether data blocks to be stored to that logical volume are compressible during replication. Subsequently, with receipt of a data block at the first storage array to be stored to the logical volume, a check of the compressible configuration bit is made to determine whether the data block is compressible during replication, and if so, the data block is compressed for replication. The compressible configuration bit is placed into the payload region of the data packet being replicated to the second storage array. At the second storage array, the compressible configuration bit is used to determine whether to uncompress the replicated data block.

Abstract: Embodiments of the present invention provide a method, system and computer program product for software requirements extraction from external sources for software development. In an embodiment of the invention, a method for software requirements extraction from external sources for software development includes retrieving content from over a computer communications network pertaining to a product. The content can include by way of example, a Web page, e-mail message, instant message, blog posting or social network posting, to name only a few. Within the content, a modal verb can be identified and text extracted that is proximate to the modal verb. Thereafter, a requirement can be generated for a revision of the product based upon the extracted text. Optionally, the requirement can be ranked according to the modal verb, for example, an imperative modal verb can correspond to a higher ranking than a suggestive modal verb.

Abstract: Using an authentication server to discover one or more additional authentication servers and to dynamically establish a trust relationship with the one or more additional authentication servers. The authentication server searches for the one or more additional authentication servers to discover one or more sources of authentication tokens, and inspects an incoming authentication request from the one or more additional authentication servers to determine if the request is carrying one or more authentication tokens from a newly discovered realm. Once the authentication server determines a newly discovered realm to be trustworthy, the authentication server receives a directory schema from the newly discovered realm and compares the received directory schema with a known directory schema retrieved by the authentication server to identify an intersection of the received directory schema and the known directory schema.

Abstract: A system thinker application receives a first issue, a first resolution to the first issue, and a first plurality of skills. The system thinker application searches a system environment electronic profile for a second issue, a second resolution to the second issue, and a second plurality of skills, wherein the system environment electronic profile contains a plurality of component profiles, and wherein the plurality of component profiles contain a second issue, a second resolution to the second issue, and a second plurality of skills. The system thinker application determines if the first issue, the first resolution to the first issue, and any one of the first plurality of skills are similar to any one of the second issue, the second resolution to the second issue, and any one of the second plurality of skills. The system thinker application adds skills to the system environment electronic profile and the component profile.

Abstract: Disclosed are a method, information processing system, and computer readable medium for resource recovery. The method comprises associating at least one bit with at least one block of memory. The bit denotes a borrow status for the block of memory. The bit is set for resource recovery. A resource recovery event is detected and in response to the bit being enabled for resource recovery, the block of memory is borrowed for a given duration of time. The block is borrowed to temporarily store information associated with the resource recovery there into until the information is written to persistent storage.

Abstract: Disclosed are a method, electronic device, and computer readable medium for determining an end-of-life stage of the flash memory. The method includes detecting at least one life cycle event associated with a flash memory residing on an electronic device. A counter that is associated with the life cycle event is then incremented. Based on the counter, a total number of occurrences for the one life cycle event is determined. The total number of occurrences for the at least one given threshold is also determined. A current life cycle stage of the flash memory is identified based at least in part on determining if the total number of occurrences exceeds at least one given threshold. The life cycle stage is associated with the at least one given threshold. A user is then notified of the life cycle state of the flash memory.

Abstract: Storing and operating an information object. An indicator associated with the information object is read. The indicator indicates that a historical information is stored for the information object. Responsive to determining from the historical information that the information object has been historically accessed, (a) future access time based on the historical information is determined; (b) a trigger for placing the information object in a storage device at a predetermined time before the future access of the information object is scheduled, the trigger being associated with a scheduled time; and (c) responsive to the scheduled time elapsing, the trigger is executed. When the trigger is executed, the information object is placed in said storage device.

Abstract: A method and system are provided for managing requests to access data in a computer environment. In one aspect of the present invention, a request manager receives a request associated with meta data corresponding to data that is maintained separately from the meta data. In another aspect, the request manager informs a data object manager of an anticipated request that will be received by the data object manager to enable it to prepare for the anticipated request. The data object manager commences preparing for the anticipated request in response to being informed of the anticipated request to facilitate a reduction in data access time. In one example of a computing environment utilizing one or more aspects of the invention, a storage subsystem comprising a data object manager prepares for the anticipated request by pre-fetching data blocks from storage media into a cache.
