Abstract: A technique is provided by which a JMX management console can be created that reduces the time and expense needed to create the console, and which reduces the likelihood of errors being introduced. A method for providing an interface comprises providing a software object including a representation of a graphical user interface, requesting from the software object the representation of the graphical user interface, and displaying the graphical user interface.

Abstract: An application tuning tool, and method, system, and computer program product for application tuning, provides application deployers with a single, unified facility for modifying the relevant parameters to achieve optimal performance, which makes the application tuning process simpler and easier, so that it can be performed by less skilled individuals and yet be performed more quickly by those less skilled individuals. A method of tuning an application deployed in an application server comprises the steps of deploying the application in the application server, invoking an application tuning tool operable to display information relating to application parameters to be tuned, receiving specifications of values of application tuning parameters, and tuning the application using the received specified parameter values.

Abstract: An optical signal propagating through a transmission line of a multimode fiber is branched by an MMF coupler of a reception device, and the intensity of the signal is detected by a MMF monitor PD. After connecting from the multimode fiber to a single-mode fiber, the optical signal is branched by a SMF coupler, and the intensity of the optical signal after the connection by a SMF monitor PD is detected. A coupling loss is calculated from the two detection results and the status of the occurrence of an error rate is estimated from the obtained coupling loss.
