Abstract: In accordance with embodiments, there are provided mechanisms and methods for providing interoperable management of application servers. These mechanisms and methods can enable a software developer to create client applications using one or more programming systems, i.e., .NET, C++, VISUAL C++, etc. that can discover and interact with management resources, such as objects, functions and so forth, deployed on an application server, such as an application server implemented using a disparate programming system, i.e., a J2EE Application server, for example. Embodiments employing interfaces that conform to an implemented standard, i.e., Web Service Description Language (WSDL), for example and conform to an implemented protocol, such as Simple Object Access Protocol (SOAP), Hyper-Text Transfer Protocol (HTTP) for example, can enable third parties, for example, to create software to monitor managed applications and/or servers.

Abstract: A highly agile low phase noise frequency synthesizer is provided for rapid generation of frequency specific signals. The frequency synthesizer is capable of rapidly generating signals at different output frequencies while maintaining low cross-coupling. Two or more signal generators utilize a reference frequency to generate two or more signals. These signals are limit processed to reduce cross-coupling prior to being presented to a switch. Responsive to a control signal, the switch outputs one of the signals to a frequency modification device, such as a frequency divider or multiplier. Responsive to a control signal, the frequency modification device scales the frequency of the switch output to convert the frequency of the switch output signal to a desired output frequency. By maintaining sufficient frequency separation between the switch input signals cross-coupling and phase noise is minimized and implementation on an integrated circuit may be achieved.

Abstract: In accordance with one embodiment of the present invention, there are provided mechanisms and methods for providing an application programming interface (API) for managing applications deployed on one or more servers. These mechanisms and methods can enable a software developer to create a single program that can discover and browse resources, such as JDBC connection pools, deployed applications and other resources, on any J2EE Application server, for example. In an embodiment, the APIs are part of the J2EE Management Specification, which specifies interface mechanisms for J2EE Application servers to describe their resources using a standard data model. Embodiments employing APIs conforming to the J2EE Management Specification can enable third party software, for example, to be used to monitor the applications.

Abstract: In one embodiment, services are not loaded if they are not needed by the user and if no services needed by the user are dependent upon them. In one embodiment, server services are represented as nodes in a graph data structure. Connections between the nodes indicate dependencies between the server services. The graph is sorted to create an ordered list of services which can be used to startup the services. In another embodiment a server services manager reads license files and user inputs and marks the ordered list of services to indicate which services are to startup.

In another embodiment the light weight server installer is an internet installer, enabling the user to download over the internet only the components necessary to implement the selected functionality.

Abstract: According to one exemplary embodiment, a frequency synthesizer module includes a loop filter, where the loop filter includes a capacitor having a first terminal and a second terminal. The frequency synthesizer module further includes a loop filter calibration module coupled to the capacitor in the loop filter. The loop filter calibration module causes an initial capacitance between the first terminal and the second terminal of the capacitor to increase to a target capacitance when the loop filter is in a calibration mode. The target capacitance can causes in increase in control of a bandwidth of the loop filter and a reduction in percent error of a unity gain bandwidth of the loop filter. The loop filter further includes a switched capacitor array configured to cause the initial capacitance to increase to the target capacitance in response to a digital feedback signal provided by the loop filter calibration module.

Abstract: A synchronous prescaler is provided that has an input line for receiving an input signal, which is synchronized to a low order dual modulus prescaler. The dual modulus prescaler generally divides responsive to a mode command line, but may have a dead-zone period where it may fail to respond to a generated mode command. The dual modulus prescaler also has an output line that is synchronized to an extender section. The extender section is used to further divide the input signal, and is synchronized to an adjustable counter section. A sync controller circuit receives an output from the counter section, as well as a timing signal from the extender, and generates the mode signal on the mode command line. In this arrangement, the sync controller generates the mode signal at a time when the low order dual modulus is in a condition to change divide modes, thereby avoiding providing the signal during the dead-zone period.
