    摘要: To dynamically update an operating system, a new factory object may have one or more new and/or updated object instances. A corresponding old factory object is then located and its version is checked for compatibility. A dynamic update procedure is then executed, which includes (a) changing a factory reference pointer within the operating system from the old factory object to the new factory object. For the case of updated object instances, (b) hot swapping each old object instance for its corresponding updated object instance, and (c) removing the old factory object. This may be performed for multiple updated object instances in the new factory object, preferably each separately. For the case of new object instances, they are created by the new factory and pointers established to invoke them. A single factory object may include multiple updated objects from a class, and/or new object instances from different classes, and the update may be performed without the need to reboot the operating system.

    摘要: A system, method and computer program product for enhancing a real-time operating system (RTOS) with functionality normally associated with a general purpose operating system (GPOS). A hypervisor that is adapted to perform a real-time scheduling function supports concurrent execution of an RTOS and a GPOS on a system of shared hardware resources. The RTOS or its applications can utilize services provided by the GPOS. Such services may include one or more of file system organization, network communication, network management, database management, security, user-interface support and others. To enhance operational robustness and security, the hypervisor can be placed in read-only storage while maintaining the ability to update scheduling mechanisms. A programmable policy manager that is maintained in read-write storage can be used to dictate scheduling policy changes to the hypervisor as required to accommodate current needs.

    摘要: Systems, especially operating systems, are becoming more complex to the point where maintaining them by humans is becoming nearly impossible. Many corporations have recognized this trend and have begun investing in autonomic technology. Autonomic technology allows a piece of software to monitor, diagnose, and repair itself. This can be used for improved performance, reliability, maintainability, security, etc. Disclosed herein is a mechanism to allow operating systems to hot swap a piece of operating system code, while continuing to offer to the user the service which that code is providing. This can be used, for examples, to increase the performance of an application or to fix a detected security hole live without bringing the machine down. Some autonomic ability will be mandatory in next generation operating system for without it they will collapse under their own complexity. The invention offers a key component of being able to achieve autonomic computing.

    摘要: A server computer system includes a keep-alive autonomic adjustment mechanism that monitors current operating conditions and dynamically adjusts the keep-alive specification to optimize the keep-alives for the current operating conditions. The keep-alive autonomic adjustment mechanism monitors the total number of clients, and the average number of requests per client. The value of a keep-alive specification that determines how log to keep a connection open may be dynamically and autonomically adjusted by the keep-alive autonomic adjustment mechanism according to the monitored current operating conditions. The keep-alive autonomic adjustment mechanism may also include the ability to autonomically enable and disable the keep-alives. In this manner the performance of the server may be tuned to optimize the effect of using keep-alives according to current operating conditions.

    摘要: A method, system, and computer program product for optimizing “Hypertext Preprocessor” (PHP) processes by identifying the PHP pages which are active on a server and forwarding requests for specific pages to a processor which has recently processed that page. A request processing optimization (RPO) utility assigns an initial request received at the server for a PHP page based on a number of factors which may include a relative usage level of a processor within a pool of available processors on a server. The RPO utility assigns a request to additional processors based on: (1) a threshold frequency of page requests; and (2) a resource intensive factor of a page request measured by average response time of the page request. The assignment of PHP pages to a particular processor(s) enhances cache performance since the requisite code for a specific PHP page is loaded into the processor's cache.

    摘要: A method, apparatus, system, and signal-bearing medium that, in an embodiment, calculate the average number of servers that executed an application in a previous time period, decide whether the current number of servers that execute the application is less than the average number of servers, and, if so, power on the average number of servers. The application is then distributed across the average number of servers. In an embodiment, the server is powered on by increasing the clock speed of the processors associated with the servers. In an embodiment, a determination is periodically made whether the response time of the application is greater than a threshold, and, if so, the servers are powered on and the application is distributed across the servers. In an embodiment, a determination is periodically made whether the response time of the application is less than a threshold, and, if so, servers are powered off and the application is distributed across the remaining servers.
