The Apache JMeter is a 100% pure Java desktop application designed for performance and load testing of servers. It was primarily designed for Web/HTTP testing but it has been expanded to include support for a variety of testing modules. It ships with modules for HTTP and SQL databases (using JDBC). It may be used to test server performance both on static and dynamic resources, to simulate a heavy load on a server or network to test its strength, or to analyse overall performance under different load types. It also provides pluggable interfaces for customizing data visualization, test synchronization, and the construction and execution of tests.
RvSnoop is a Swing-based GUI that provides developers and operations support personnel with a sophisticated, feature-rich interface for tracing TIBCO Rendezvous messages. Benefits include the ability to filter out subjects that you are interested in, and the ability to reduce the time required to locate specific messages. Features include real-time subject filtering, a customizable logging table view, a subject tree with navigation and filtering, full text searching of logged messages and subjects, the ability to save configuration for later sessions, the ability to configure the number of log records to be displayed simultaneously, customizable record colors, configurable font face and size, customizable log table column layout, integration with Tibco rvscript, saving a table to HTML, and display and filtering of MTrackingInfo tracking IDs.
ManekiNeko is a parser configuration that allows users to validate documents using Relax NG grammars and access the document information using standard programming interfaces. The parser configuration does not implement a Relax NG validator, however. Instead, it wraps James Clark's Jing validator to validate documents using a Relax NG grammar.
Enterprise Object Broker (EOB) is an application server that transparently distributes Java objects via their interfaces. It makes no distinction between Local and Remote objects. Because of these features, it is not J2EE compliant. The developer builds beans that implement normal Java interfaces and the deployer decides where the beans are in a cluster of servers. Apache's AltRMI is used in place of RMI. It publishes plain interfaces locally and remotely. The interfaces do not have to extend the java.rmi.Remote interface. Methods do not have to throw RemoteException. AltRMI delivers remoting for Java. EOB sits on top of Apache's Avalon-Phoenix server platform.
mod_backhand is a load balancing module for Apache. It provides per-request HTTP redirection within a heterogeneous Apache server cluster. Each request is processed and run through a set of "candidacy functions" to determine which server is best suited to respond. The request is then proxied to that server. Facilities are in place to allow you to write your own dynamically loadable decision making algorithms. Everything about the request and the current availability of resources can be used in the decision-making process.
