Manage installed applications for your application server

You can use the HTTP Server Adminsitration interface to manage the applications that are deployed in your application server instance. You can use the interface to perform the basic tasks required to manage applications.

To manage your installed applications on an application server, follow these steps:

1. Start the HTTP Server Administration interface.
2. Click the Manage tab.
3. Select an application server from the Server list.
4. Expand Applications.
5. Click Manage Installed Applications.

From the Manage Installed Applications form, you can do the following:

• Start or stop an application
• Enable or disable an application
• Edit the virtual host mapped to a Web module
• Update an application
• Uninstall an application

Start or stop an application

1. Select an application from the Installed applications table.
2. Click Start to start an application.
3. Click Stop to stop an application.

Note: The start button is not available if the application is running or if it is disabled.

Enable or disable an application

1. Select an application from the Installed applications table.
2. Click Properties.
3. Click the General tab in the Application Properties form.
4. Select one of these options from the Application enablement field.
   • Enabled
     Select Enabled. Enabled applications start automatically when you start the application server.
   • Disabled
     Select Disabled. Disabled applications do not start when you start the application server. You cannot run an application that is disabled.
5. Click Apply or OK to save your changes.

Edit the virtual host mapped to a Web module

1. Select an application from the Installed applications table.
2. Click Properties.
3. Click the Virtual Host Mapped to Web Modules tab in the Application Properties form.
4. Select a Web module from the Web modules and corresponding virtual hosts for application table.
5. Select a virtual host to map to a Web module. The virtual host determines the IP address or hostname that is used to access your application. See Manage virtual hosts for your application server for information on creating new virtual hosts.
6. Click Apply or OK to save your changes.

Update an application

Updates to applications redeploys it for your application server. It does not change configuration attributes.

1. Select an application from the Installed applications table.
2. Click Stop if the application is running.
3. Click Update.
4. Select select one of these options.
   • Application is contained in an EAR file
     1. Click Browse or specify the fully qualified path name of the EAR file on your iSeries.
   • Application is contained in a WAR file
     1. Click Browse or specify the fully qualified path name of the WAR file on your iSeries.
   • Optional: Select Pre-compile JSPs to compile JSP files into Java servlet code during the installation of the application. If the JSP files do not need to be compiled at runtime, the application server performance can improve. However, depending on the number of JSP files in the application and the size of your system, pre-compiling all JSP files can cause the install of the application to take a significant amount of time.
5. Click Update.

Uninstall an application

1. Select an application from the Installed applications table.
2. Click Stop if the application is running.
3. Click Uninstall.
4. Click OK.
5. Click Refresh to update the Installed applications table.
