摘要： A database access facility for accessing databases includes a monitoring function which monitors accesses by requesters of database data. The monitoring function tracks which database fields are requested to dynamically determine the fields which the application needs. Once sufficient tracking data is obtained, subsequent accesses to the database on behalf of an application are automatically modified by the application server to request only the fields which are likely to be needed. Preferably, the database access facility is an application server for one or middle tier applications which access the database on behalf of multiple clients in a three-tier client-server environment.

摘要： In an embodiment, a selection of an original transaction is received. In response to the selection of the original transaction, a call stack of the application that sends the original transaction during a learn mode of the application is saved. A specification of a new transaction and a location of the new transaction with respect to the original transaction in an transaction stream is received. During a production mode of the application, the original transaction is received from the application. A determination is made that the call stack of the application during the production mode matches the saved call stack of the application during the learn mode. In response to the determination, the new transaction is inserted at the location into a transaction stream that is sent to a database.

摘要： In an embodiment, a request is received that is directed to a page. A determination is made whether a session associated with the request already exists by determining whether the request is dependent on a previous request. If the session does not already exist, then a decision is made whether the request will result in creating a session. If the request will result in creation of a session, then a server is selected based on a load-balancing metric instance associated with the page, and the request is sent to the selected server. The load-balancing metric instance has an algorithm and an input parameter to the algorithm. The server is selected by executing the algorithm and selecting the server identified by an output parameter from the algorithm.

摘要： Real world energy usage can be reduced using a virtual environment. A virtual universe energy conservation system (“system”) can determine comprehensive energy usage at a physical site where a client accessing a virtual universe is located. The system can determine that the comprehensive energy usage at the physical site exceeds an energy usage threshold. The system can also notify a virtual universe user account associated with the client that the comprehensive energy usage at the physical site exceeds the energy usage threshold.

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.
摘要翻译： 一种方法，系统和计算机程序产品，用于通过识别服务器上活动的PHP页面并将特定页面的请求转发到最近处理该页面的处理器来优化“超文本预处理器”（PHP）进程。 请求处理优化（RPO）实用程序根据可能包括服务器上的可用处理器池中的处理器的相对使用级别的因素来分配针对PHP页面在服务器处接收的初始请求。 RPO实用程序基于以下方式向其他处理器分配请求：（1）页面请求的阈值频率; 和（2）通过页面请求的平均响应时间测量的页面请求的资源密集型因素。 将PHP页面分配给特定处理器可以增强缓存性能，因为特定PHP页面的必需代码将加载到处理器的缓存中。

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.
