Abstract: A method, system and apparatus for autonomic buffer configuration. In accordance with the present invention, an autonomic buffer configuration method can include monitoring data flowing through buffers in a communications system and recording in at least one buffer profile different data sizes for different ones of the data flowing through the buffers during an established interval of time. An optimal buffer size can be computed based upon a specification of a required percentage of times a buffer must be able to accommodate data of a particular size. Subsequently, at least one of the buffers can be re-sized without re-initializing the at least one resized buffer.

Abstract: Automatic optimization of application performance parameters is provided. This optimization may be provided by identifying the resource demands of applications using virtual resources, identifying the virtual resources that can be available to the applications, and allocating the virtual resources to the applications to be run on a virtual machine.

Abstract: Embodiments of the present invention address deficiencies of the art in respect to threading model switching between asynchronous I/O and synchronous I/O models and provide a novel and non-obvious method, system and computer program product for autonomic threading model switching based upon I/O request types. In one embodiment, a method for autonomic threading model switching based upon I/O request types can be provided. The method can include selectably activating and de-activating a blocking I/O threading model according to a volume of received and completed blocking I/O requests.

Abstract: The present invention is a method, system and apparatus for highly efficient connection pool management. In a preferred aspect of the invention, a highly efficient connection pool management system can include a connection pool configured to store one or more idle connections. The system further can include a connection manager programmed for coupling to the connection pool. The connection manager further can be programmed to validate individual ones of the idle connections by issuing a non-blocking input/output (I/O) operation to each of the individual ones of the idle connections.

Abstract: Under the present invention, when a TCS receives a data command (e.g., a read or write command) pursuant to a communication session between the TCS and an application, it will first request permission from a permission system to execute the data command. By applying a set of rules to a setting of a state variable associated with the TCS, the permission system will determine whether to grant the permission. If so, the TCS will execute the data command and change the setting of the state variable. If a close command is later received by the TCS to close the communication session, permission will once again be requested from the permission system, which will again apply a set of rules to the current setting of the state variable to determine if the session can be safely closed.

Abstract: In a computer network environment, a server protocol is provided to process read requests from clients. Rather than all read requests being processed synchronously or all read requests being processed asynchronously, an attempt is first made to perform a synchronous read. If the synchronous read is unsuccessful, the connection through which the request was received by the server is registered with a monitoring service. When the data is ready to be read, an appropriate callback is called and the data transmitted. An optional delay may be imposed before the synchronous read is attempted to increase the likelihood that the attempt will be successful. A series of delays/read attempts may also be employed in order to increase the likelihood still further that an attempt will be successful.

Abstract: The present invention is a method, system and apparatus for memory leak detection and reporting. In a preferred method of the invention, allocated ones of resources in a resource pool can be time stamped upon allocation and calling code segments receiving the allocated resources can be identified. Memory leaks can be detected by inspecting individual timestamps for the allocated resources to determine whether the allocated resources have become overly idle. Notably, the identifying step can include the step of retrieving identities for individual ones of the calling code segments from an associated calling stack when the individual ones of the calling code segments acquire one of the allocated resources. In any case, for each allocated resource determined to have become overly idle, an identity of a corresponding one of the calling code segments can be reported.

Abstract: A method of providing updated host screen information to a client application utilizing a request-response communications model includes establishing a first connection between the client application and a server application, wherein the server application provides updated host screen information to the client application in response to requests from the client application. A second connection is established between a monitor application and the server application. A notification of the availability of updated host screen information is received via the second connection at the monitor application. The updated host screen information is requested over the first connection responsive to receiving the notification. The requested updated host screen information is received at the client application and displaying utilizing the client application. Related systems and computer program products are also disclosed.
