Using WLST Commands for System Components

Getting Started Managing Oracle Fusion Middleware 3-19 For example, to view the status of an Oracle Virtual Directory instance named ovd1, use the following command: opmnctl status ias-component=ovd1 You can use OPMN to start and stop system components, monitor system components, and perform many other tasks related to process management. For example, you can use the following commands to start and stop OPMN and all OPMN-managed processes, such as Oracle HTTP Server and Oracle Web Cache: opmnctl startall opmnctl stopall To start a component, use the following command: opmnctl startproc componentName [, componentType] [, componentSet For example, to start an Oracle HTTP Server instance named ohs1, use the following command: opmnctl startproc ias-component=ohs1

3.6 Getting Started Using the Fusion Middleware Control MBean Browsers

A managed bean MBean is a Java object that represents a JMX manageable resource in a distributed environment, such as an application, a service, a component or a device. MBeans are defined in the Java EE Management Specification JSR-77, which is part of Java Management Extensions, or JMX, a set of specifications that allow standard interfaces to be created for managing applications in a Java EE environment. For information about JSR-77, see: http:java.sun.comj2eetoolsmanagement You can create MBeans for deployment with an application into Oracle WebLogic Server, enabling the application or its components to be managed and monitored through Fusion Middleware Control. Fusion Middleware Control provides a set of MBean browsers that allow to you browse the MBeans for an Oracle WebLogic Server or for a selected application. You can also perform specific monitoring and configuration tasks from the MBean browser.

The following topics describe how to view or configure MBeans: ■ Using the System MBean Browser ■ Using the MBeans for a Selected Application

3.6.1 Using the System MBean Browser

You can view the System MBean Browser for many entities, including an Oracle WebLogic Server domain, an Administration Server, a Managed Server, or an application. You can search for an MBean, filter the list of MBeans, and refresh the list of MBeans in the MBean navigation tree. To view the System MBean Browser specific to a particular Oracle WebLogic Server Managed Server and to configure and use the MBeans: 1. From the target navigation pane, expand the farm, then WebLogic Domain, and then the domain. 2. Select the Managed Server. 3. From the WebLogic Server menu, choose System MBean Browser. The System MBean Browser page is displayed. 4. Expand a node in the MBean navigation tree and drill down to the MBean you want to access. Select an MBean instance. If you do not know the location of an MBean, you can search for the MBean: a. Click the Find icon at the top of the MBean navigation tree. b. For Find, select MBean Name. You can also select Attributes, Operations, or JMX syntax. c. Enter the name of the MBean and click the arrow. 5. To view the MBeans attributes, select the Attributes tab. Some attributes allow you to change their values. To do so, enter the value in the Value column. 6. To view the available operations, select the Operations tab. To perform an operation, click the operation. The Operations page appears. Enter any applicable values and click Invoke.

3.6.2 Using the MBeans for a Selected Application

You can view, configure, and use the MBeans for a specific application by taking the steps described in Section 3.6.1 , and drilling down to the application. As an alternative, you can navigate to an applications MBeans using the following steps: 1. From the target navigation pane, expand the farm, then Application Deployments. 2. Select the application. 3. From the Application Deployments menu, choose System MBean Browser. The System MBean Browser page is displayed, along with the MBean information for the application.
