    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.

    摘要： Apparatus and accompanying methods for use in preferably a multi-system shared data (sysplex (5)) environment which quickly and efficiently isolates (fences), through a pre-defined hierarchical order, failed sysplex components from accessing shared data in order to protect data integrity. Specifically, by dividing a sysplex workload into specified fence groups (FG A, FG B) and providing appropriate software and hardware fence support, fencing can occur at various distinct levels: a member-to-member level, i.e. to allow any member (220, 225, 230, 233,237) of a fence group to fully isolate any other ("target") member of that same group; a fence group level, i.e. to isolate all members of a fence group that execute on a "target" system (200.sub.1, 200.sub.2, 200.sub.3); and a system level, i.e. to fully isolate an entire "target" system. Through pre-defined escalation rules (630), fencing can be escalated from a lower member level to a higher, group or system, level in the event a lower level fence can not be successfully imposed. Member level fencing is accomplished in software (1300, 1500); group and system level fencing is accomplished through dedicated hardware fencing facilities (44). An identifier (444, 464) uniquely designates each different fence group existing on a computer processing complex (CPC) (40.sub.1, 40.sub.2, 40.sub.3, 40.sub.M) in the sysplex over the life of that CPC. Advantageously, this technique eliminates erroneous back level fencing, significantly expedites fence processing and also greatly reduces a need for human intervention.

    摘要： A method and system for managing one or more coupling facilities in a data processing system. An active policy is used to control resources located in the coupling facilities. The active policy can be changed such that control of the resources can be altered. Compatible changes are made immediately and incompatible changes are made at a subsequent time. Recorded in the active policy and in the coupling facilities is information regarding the resources. When the information in the active policy is not in synchronization with the information in the coupling facilities, a reconciliation technique is performed. The resources in the coupling facilities can be modified but prior to the modification, the intended modifications are stored in the active policy.

    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： One or more central processing complexes (CPC's), each with one or more programs being executed, issue commands to a structured electronic storage (SES). The commands include ones that create or delete data structures in SES, and attach or detach users to the data structures. The commands include a comparative authority value operand and a new authority value operand. A data structure or user control information has an associated existing authority value. If the comparative authority value matches the existing authority value, the existing authority value is replaced by the new authority value, and the command is executed. If there is a mismatch, the existing authority value is returned to the program that issued the command, and the command is not executed in SES. This enables software to serialize management of SES and maintain a consistent view of objects in SES in the presence of faulty CPC's, without causing correctly operating CPC's to experience errors or undue delays.

    摘要： Apparatus for recovering resources in a data processing system having at least one CPC including at least one central processor for executing instructions arranged in programs for processing data, a main storage for storing data and said programs, and including a structured external facility, and multiple message paths connected between the CPC and the structured external storage facility for passing data, messages and responses therebetween. The CPC includes multiple indicators, one for each message path, and vectors which indicate the validity of data shared by the main storage with the structured external storage facility. A message path status facility determines if any of the message paths become unavailable. If any of the message paths is determined to be unavailable, its indicator is set, and a recovery of resources is started. The status of each message path is tested. If the message path is not available, an attempt is made to make it available to the central processor for passing data, messages and responses. If all message paths connecting a CPC to the SES become unavailable, the vectors are cleared indicating that the shared data is no longer valid.
