Method and apparatus for loading new code in the initial program load (IPL) path to reduce system restarts may be provided by receiving a new component for an operating system (OS) running on a computing device; identifying a given component of the OS that is currently running as corresponding to the new component; updating a header of the given component to indicate that the given component is to-be-updated a filepath for the new component; upon initializing the operating system during a subsequent boot of the computing device, checking the header of the given component when loading the given component from an IPL path for the OS to determine that the given component is to-be-updated, and in response: loading the new component into the IPL path according to the filepath within the header of the given component; removing the given component from the IPL path; and executing the new component.

Disclosed aspects relate to local encryption of a set of replicated data in a shared pool of configurable computing resources which has a set of member nodes. A first local encryption key for the first node of the set of member nodes may be determined. The first local encryption key for the first node of the set of member nodes may be generated. A second local encryption key for the second node of the set of member nodes may be determined. The second local encryption key may differ from the first local encryption key. The second local encryption key for the second node of the set of member nodes may be generated. A temporary key for utilization by both the first and second nodes may be generated. The set of replicated data may be updated using the first local encryption key, the temporary key, and the second local encryption key.

Replicated encrypted data management

A method, and system for implementing enhanced fast full synchronization for remote disk mirroring in a computer system. A source backup copy is made locally available to a target for remote disk mirroring. Sectors are identified that are different between the source and target. A hash function is used over a block to be compared, with an adaptive number of tracking sectors per block, starting with a minimum block size.
