Abstract
Abstract 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
92 words
A method for capturing data in a data processing system having one or more operating systems coupled to a coupling facility, said method comprising the steps of: detecting when an operating system loses communication with said coupling facility; and requesting a dump of information stored within said coupling facility, said dump including serviceability information from said operating system which lost communication with said coupling facility, said serviceability information including control structures usable in at least one of locating customer data of said operating system and in determining status of said customer data.
Claim 2
Independent Claim
92 words
A method for capturing data in a data processing system having one or more operating systems coupled to a coupling facility, said method comprising the steps of: detecting when an operating system loses communication with said coupling facility; and requesting a dump of information stored within said coupling facility, said dump including serviceability information from said operating system which lost communication with said coupling facility, said serviceability information including control structures usable in at least one of locating customer data of said operating system and in determining status of said customer data.
Claim 3
Independent Claim
96 words
A system for capturing data in a data processing system having one or more operating systems coupled to a coupling facility, said system for capturing data comprising: means for detecting when an operating system loses communication with said coupling facility; and means for requesting a dump of information stored within said coupling facility, said dump including serviceability information from said operating system which lost communication with said coupling facility, said serviceability information including control structures usable in at least one of locating customer data of said operating system and in determining status of said customer data.
Claim 4
Independent Claim
96 words
A system for capturing data in a data processing system having one or more operating systems coupled to a coupling facility, said system for capturing data comprising: means for detecting when an operating system loses communication with said coupling facility; and means for requesting a dump of information stored within said coupling facility, said dump including serviceability information from said operating system which lost communication with said coupling facility, said serviceability information including control structures usable in at least one of locating customer data of said operating system and in determining status of said customer data.
