The first communication apparatus () comprises: an access request issuing unit () which issues a request which denotes the function thereof to the second communication apparatus (); and a conflict assessment unit () which, either when the request and a request which the second communication apparatus () has issued conflict or when the request is rejected, makes the access request issuing unit () reissue a request to the second communication apparatus () which denotes another function. 1. A communication apparatus including a data storing section and being capable of serving at least one of a role as a device for allowing another communication apparatus at a position remote from the communication apparatus to access the data storing section and a role as a host for accessing a data storing section included in the other communication apparatus , the communication apparatus comprising:an access control section that controls the role to be served by the communication apparatus;an access request issuing section that issues, to the other communication apparatus, a request that the communication apparatus serve one of the roles that the communication apparatus is capable of serving;an acquisition section that acquires, via the access control section, a request issued by the other communication apparatus and that acquires a response to the request issued by the access request issuing section; anda conflict determining section that reissues, to the other communication apparatus via the access request issuing section, a request that communication apparatus serve the other role in accordance with the roles that ...

Method and apparatus for cause analysis involving configuration changes

A technique determines which configuration change(s) caused an application invocation failure of a computer application without the need for a knowledge database. To determine which configuration change is the most likely cause, the cause analysis program checks other computers that have experienced the same configuration changes. The cause analysis program checks and counts the application invocation results before and after each configuration change is done. If the same configuration changes are found in the other computers, the program checks whether each configuration change caused or cured the same problem in that computer. The program counts the similar cases for all of the computers. Subsequently, the program calculates the ratio of those instances involving a change from success to failure and the ratio of those instances involving a change from failure to success out of all instances for each configuration change.
