Requesting a dump of information stored within a coupling facility, in which the dump includes serviceability information from an operating system that lost communication with the coupling facility

摘要

A method and system for capturing and controlling access to information in a data processing system are 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.
