    摘要： The amount of host real storage provided to a large guest storage buffer is controlled. This control is transparent to the guest that owns the buffer and is executing an asynchronous process to update the buffer. The control uses one or more indicators to determine when additional host real storage is to be provided.

    摘要： Aliasing errors, occasioned by, for example, a programming error resulting in including extra or missing bits in a storage address, wrong addressing mode, or wrong address context, are detected by providing a storage address configuration including gaps in valid addresses. Such a programming error is detected and an exception is thrown (that is, an addressing error is detected and indicated) responsive to an address reference to such a gap in valid addresses. Gaps are configured at complementary address ranges to facilitate detection of such aliasing errors.

    摘要： In a multi-processing computer system, a method for serializing references to shared data objects, such as pages, tables, and the like, that permits the system processes to reference objects on a shared access basis without obtaining a shared lock. A point of execution of the control program is monitored that is common to all processes in the system, which occurs regularly in the execution of each process and across which no references to any data object can be maintained by any process, except references using locks. A system reference point is established, which occurs after each process in the system has passed the monitored point of execution at least once since the last such system reference point. Operations requiring exclusive access, such as modification or destruction of the data object, are performed by, first, obtaining a conventional exclusive lock, then preventing any subsequent references to the data object, waiting until two of the system reference points have occurred, and, finally, performing the operation. Significant reductions in overhead can be achieved through the application of the invention.
