    摘要: An abnormal termination recovery is performed where storage is referenced shortly after the storage has been freed. More specifically, when storage is freed, and that storage is accessed, an abnormal termination error (e.g., a page translation exception event) occurs due to referencing storage that has not been obtained. When the abnormal termination error occurs, an abnormal termination recovery operation is accessed. The abnormal termination recovery operation scans a history of storage freeing operations (e.g., FREEMAIN operations) to determine whether the storage location accessed by the storage access that caused the abnormal termination error was recently freed from within the same address space. If the storage location was recently freed, then the abnormal termination recovery operation reverses the storage freeing operation by issuing a storage obtaining operation (e.g., a GETMAIN operation) to re-obtain the storage.

    摘要: Computer systems and computer program products for automating tasks in a computing environment are provided. In one such embodiment, by way of example only, if an instant task is not found in one of list of included tasks and a list of excluded tasks, at least one of the following is performed: the instant task is compared the with previous instances of the task, if any; the instant task is analyzed, including an input/output (I/O) sequence for the instant task, to determine if the instant task is similar to an existing task; and the instant task is considered as a possible candidate for automation. If the instant task is determined to be an automation candidate, the instant task is added to the list of included tasks, otherwise the instant task is added to the list of excluded tasks.

    摘要: A method to dynamically adjust the amount of free space in a storage group is disclosed herein. In certain embodiments, such a method may include monitoring the amount of free space in an active storage group. The method may further include maintaining an overflow storage group containing unused volumes. When the free space in the active storage group falls below a lower threshold value, the method may automatically move a volume from the overflow storage group to the active storage group. Conversely, when the free space in the active storage group exceeds an upper threshold value, the method may automatically transfer data from a volume in the active storage group to other volumes in the active storage group, and move the volume from the active storage group to the overflow storage group. A corresponding computer program product and apparatus are also disclosed herein.
