    摘要: A method and system for capturing and controlling access to information in a data processing system is provided. The data processing system includes one or more operating systems coupled to a coupling facility. When one or more operating systems lose communication with the coupling facility, a surviving operating system captures some or all of the information in the coupling facility, including that information associated with the failed operating system(s). In order to capture the information when a system fails or at any other time, the information in the coupling facility is serialized, thereby preventing all access to the information except for those commands capturing the information. While the information is serialized, requests for the information are queued and then re-driven once serialization is released. If an operating system loses communication with the coupling facility during the creation of a dump, another operating system will continue the dump.

    摘要: A method and system for managing information in a data processing system is provided. The data processing system includes one or more operating systems coupled to a coupling facility. Stored within the coupling facility is data, which is accessed by one or more users. The status of those users are also stored in the coupling facility. A number of operating system services are provided for recording the users' status and managing the data and the users of the data. The data may include cache, list and/or lock structures.
