Installing Oracle WebLogic Server 11g, install WebLogic Server using the graphical installer.You can install a WebLogic plug-in on the web server, allowing it to talk to the applications running on WebLogic Server.Xml, stores the attribute values for these MBeans.When a Managed Server starts up, it contacts the Admin Server and gets a copy of the configuration information, which it stores in memory as configuration MBeans.These are persistent MBeans, and the domain's configuration file, config.The Admin Server also hosts the Edit MBean Server, which manages pending configuration changes.By default, Oracle WebLogic Server uses two listen ports to listen to incoming requests for connections.Youll see the word poll in the case of a native muxer because it uses a polling mechanism to query a socket for data.The second listen port is called an administration port.You can confirm the JVM version the server is using by viewing the command window output after you start a WebLogic Server instance.In addition, having two separate ports - one for administrative operations and the other for the application traffic - prevents a conflict between these two types of network traffic.Your WebLogic Server installation comes with plug-ins for the following web servers: Apache http Server Microsoft Internet Information Server Sun Java System Web Server You can use a proxy plug-in to proxy requests from the web server to the clustered WebLogic Server instances to provide.
Note that with a native muxer, the server creates a fixed number of threads to read incoming requests, whereas with a Java muxer you can configure the number of threads in the Administration Console by modifying the.
Important WebLogic Server Concepts, in order to fully comprehend how.
Percent Socket Readers parameter.Describe the technologies in Java Enterprise Edition.Xml file, which is modified only if you change an attribute value on the Admin Server.In general, you need to be careful about changing the number of socket reader threads.WebLogic Server uses two basic types of MBeans - configuration MBeans and runtime MBeans - to configure, monitor and manage the server and its resources.Each of the server's resources updates the relevant run-time MBean following a change in its state.Run-time values of the attributes you configure will reflect your changes immediately, and the values are persisted in the config.Native muxers are seen as providing superior performance, especially when scaling to large user bases, because they implement a nonblocking thread model.Listen Ports and Listen Threads Listen ports listen for connection requests, and as connections come in the listen thread assigned by the server to the listen port accepts the connection requests, establishes connections and hands the requests over to the socket muxer.The administration port accepts only secure SSL traffic, so all connections through this port will have to be authenticated.However, all administrative tools, such as the Administration Console, use the same MBeans and JMX API, so you don't have to reinvent the wheel by creating custom management tools.
A Java muxer uses pure Java to read data from the sockets, whereas the native muxers use platform-specific native binaries.
