A system, and computer usable program product for expanding memory size are provided in the illustrative embodiments. A desired size of an expanded memory and a first information about a workload in the data processing system are received. A size of a compressed memory pool to use with the memory to make the desired size of the expanded memory available is computed. A representation of the memory is configured, the representation of the memory appearing to be of a size larger than the size of the memory, the representation of the memory being the expanded memory, and the size of the representation being the size of the expanded memory. The expanded memory is made available such that the memory in the data processing system is usable by addressing the expanded memory.

Systems and computer program products for lock tracing at a component level are disclosed. The one or more embodiments of the invention include computer program instructions for associating one or more locks with a component of the operating system; initiating lock tracing for the component; and instrumenting the component-associated locks with lock tracing program instructions in response to initiating lock tracing. The locks are selected from a group of locks configured for use by an operating system and individually comprise locking code. The component lock tracing may be static or dynamic.
