8 Starting and Stopping WebCenter Applications

Most WebCenter application configuration changes that you make, through Fusion Middleware Control or using WLST, are not dynamic; you must restart the managed server on which the application is deployed for your changes to take effect. For example, when you add or modify connection details for Web 2.0 services (Announcements, Discussions, Documents, Mail, Instant Messaging and Presence, Search, Worklists) you must restart the application's managed server.

There are several exceptions; portlet producer and external application registration is dynamic. Any new portlet producers and external applications that you register are immediately available in your WebCenter application and any changes that you make to existing connections take effect immediately too.

This chapter includes the following sections:

• Starting Node Manager

• Starting and Stopping Managed Servers for WebCenter Application Deployments

• Starting and Stopping WebCenter Spaces

• Starting and Stopping Custom WebCenter Applications

You perform all start and stop operations from the Oracle WebLogic Server Administration Console too. .

Note: Node Manager must be running before you can start and stop administration servers, managed servers, and WebCenter applications through Fusion Middleware Control or Oracle WebLogic Server Administration Console.

Audience

The content of this chapter is intended for Fusion Middleware administrators (users granted the Admin or Operator role through the Oracle WebLogic Server Administration Console). See also, Section 1.8, "Understanding Administrative Operations, Roles, and Tools".

8.1 Starting Node Manager

Node Manager must be running before you can start and stop administration servers, managed servers, and WebCenter applications through Fusion Middleware Control or Oracle WebLogic Server Administration Console.

To start Node Manager:

1. (First time only). Before starting Node Manager, set the StartScriptEnabled property through the JAVA_OPTIONS environment variable:

   export JAVA_OPTIONS=-DStartScriptEnabled=true

2. To start the Node Manager:

   1. Navigate to WL_HOME/server/bin.

   2. From the command line, enter:

      WL_HOME/server/bin>./startNodeManager.sh

3. (First time only) Set the StartScriptEnabled property in the nodemanager.properties file:

   1. Open WL_HOME/common/nodemanager/nodemanager.properties.

      nodemanager.properties does not exist until Node Manager is started for the first time.

   2. Add the following line:

      StartScriptEnabled=true

   Once this property is set in nodemanager.properties, you do not need to define it in the JAVA_OPTIONS environment variable.

8.2 Starting and Stopping Managed Servers for WebCenter Application Deployments

Most WebCenter configuration changes that you make, through Fusion Middleware Control or using WLST, are not dynamic; you must restart the managed server on which the application is deployed for your changes to take effect.

Note: The only exceptions are portlet producer and external application registration which are both dynamic. New portlet producers and updates to existing producers are immediately available; there is no need to restart the WebCenter application or the managed server. Similarly for external application configuration.

When you start or restart the managed server, all WebCenter applications deployed on the managed server start automatically (including WebCenter Spaces).

This section describes starting and stopping managed servers throughFusion Middleware Control. See also, "Starting and Stopping WebLogic Managed Servers Using the Command Line" in Oracle Fusion Middleware Administrator's Guide.

To start, stop, or restart a managed server through Fusion Middleware Control:

1. Login to Fusion Middleware Control and navigate to the home page for WebCenter Spaces or your custom WebCenter application as follows:

   • Section 6.2, "Navigating to the Home Page for WebCenter Spaces"

   • Section 6.3, "Navigating to the Home Page for Custom WebCenter Applications"

2. Navigate to the home page for this application's managed server:

   • For WebCenter Spaces - Find WebLogic Server (Related Components section), and then click the name of the managed server. For WebCenter Spaces, this is always WLS_Spaces.

   • For custom WebCenter applications - Find Deployed On (Summary section), and then click the name of the managed server.

   The home page for the managed server displays (Figure 8-1).

   If you know the name of the managed server where your application's is deployed, you can navigate directly to this page if you expand the parent WebLogic Domain in the Target Navigation Pane.

   Figure 8-1 Managed Server Home Page

   
   

3. From the WebLogic Server menu:

   • To start the managed server, choose Control > Start Up.

   • To stop the managed server, choose Control > Shut Down.

   Alternatively, right-click the name of the managed server in the Target Navigation Pane to access menu options for the managed server.

8.3 Starting and Stopping WebCenter Spaces

It's easy to start, restart, and shut down WebCenter Spaces from Fusion Middleware Control:

• Starting WebCenter Spaces Using Fusion Middleware Control

• Stopping WebCenter Spaces Using Fusion Middleware Control

Alternatively, use WLST:

• Starting WebCenter Spaces Using WLST

• Stopping WebCenter Spaces Using WLST

Note: You can also start WebCenter Spaces through Oracle WebLogic Server Administration Console.

8.3.1 Starting WebCenter Spaces Using Fusion Middleware Control

Starting WebCenter Spaces makes the application available to its users; stopping it makes it unavailable.

To start WebCenter Spaces through Fusion Middleware Control:

1. In Fusion Middleware Control, navigate to the home page for WebCenter Spaces.

   See Section 6.2, "Navigating to the Home Page for WebCenter Spaces".

2. From the main WebCenter menu, choose WebCenter >Control > Start Up.

   Alternatively, right-click WebCenter Spaces (WLS_Spaces) in the Target Navigation Pane to access this menu option.

   A progress message displays.

3. Click Close.

Note how the application status changes to Up (Green arrow).

8.3.2 Starting WebCenter Spaces Using WLST

Use the WLST command startApplication to start WebCenter Spaces. For command syntax and detailed examples, see "startApplication" in the Oracle Fusion Middleware WebLogic Scripting Tool Command Reference.

For WebCenter Spaces, the appName argument is always webcenter.

For information on how to run WLST commands, see Section 1.12.3.1, "Running Oracle WebLogic Scripting Tool (WLST) Commands."

8.3.3 Stopping WebCenter Spaces Using Fusion Middleware Control

When you stop WebCenter Spaces no one can use it. Stopping an application does not remove its source files from the server; you can later restart a stopped application to make it available again.

When you stop WebCenter Spaces, the managed server on which WebCenter Spaces is deployed (WLS_Spaces) remains available.

To stop a WebCenter Spaces application through Fusion Middleware Control:

1. In Fusion Middleware Control, navigate to the home page for WebCenter Spaces.

   See Section 6.2, "Navigating to the Home Page for WebCenter Spaces".

2. From the main menu, choose WebCenter >Control > Shut Down.
