Understanding the WebLogic Server Directory Structure

During the WebLogic Server software installation, the installer program creates the following directory structure for a "Server with Examples" installation, which includes the WebLogic Server program files and examples files plus the secure sockets layer (SSL) encryption software packages.

 

The product directory shown here, wlserver6.1, is the default for the WebLogic Server 6.1. You can change the default name during the installation.

The contents of each directory are described in the following table.

This directory . . .	Contains . . .
bin	Executable programs plus the libraries for Windows systems to support the following components: JDBC drivers Apache plug-ins Internet Server (IS) API plug-ins Netscape Server (NS) API plug ins Other native code packages
config	A configuration repository for each of the domains in the configuration. Each domain is defined in a separate subdirectory, the name of which is the name of that domain. When you initially install WebLogic Server, three subdirectories are created in the /config directory: domain_name (mydomain is the default) examples petstore Each subdirectory contains the Extensible Markup Language (XML) configuration file (config.xml) and the security resources for that domain. The mydomain subdirectory contains two configuration files: config.xml On initial installation, config.xml reflects the values you enter during installation. As you modify your configuration, the changes are reflected in this file. config.xml.FROM_INSTALLER This file is a duplicate of the initial config.xml file, reflecting the values you enter during installation. It remains unchanged, allowing you to restore your config.xml to the state immediately following an installation, if necessary.
ext	XML jar files.
lib	The jar files to run WebLogic Server plus the libraries for UNIX systems to support the following components: JDBC drivers Apache plug-ins Internet Server (IS) API plug-ins Netscape Server (NS) API plug ins Other native code packages
samples	Sample code and resources designed to help you learn how to develop your own applications using WebLogic Server. The samples directory contains the following subdirectories: examples A collection of simple applications that demonstrate many features of WebLogic Server. petStore The WebLogic Server Pet Store application, which is a full-blown e-commerce application based on the Sun Microsystems, Inc. J2EE Blueprint example. The J2EE Blueprint example has been slightly modified to demonstrate some of the unique and powerful features of WebLogic Server. eval An evaluation copy of the Cloudscape relational database management system (RDBMS), which is included so that you can run the examples and Pet Store application with a functional RDBMS.
uninstaller	Code required to uninstall the WebLogic Server 6.1 software.
uninstaller_servicepack	Code required to uninstall the WebLogic Server 6.1 Service Pack. This directory appears only if you have applied a Service Pack upgrade to the WebLogic Server 6.1 software.
servicepacks	A copy of each Service Pack installed on the WebLogic Server 6.1 software. (Currently, this directory is not being used; it is empty.) This directory appears only if you have applied a Service Pack upgrade to the WebLogic Server 6.1 software.

Verifying Your Installation

A WebLogic Server "Server with Examples" installation contains directory structures for three different servers, as shown in the following figure. One way to verify that your WebLogic Server software is installed correctly is to start one of these servers.

Figure 7-1 WebLogic Server Directory Structures for the Default, Examples, and Pet Store Servers

 
 
 

Note: The example and Pet Store applications reside in the wlserver6.1/samples directory structure.

• Default server

  The default server, also known as the Administration Server, uses an associated configuration file (config.xml) that defines the attributes for the default server, including the default server configuration attributes that you entered during the installation process. Also provided are the following command scripts for starting the default server with the default configuration file and for setting the environment to build and run the default server: startWebLogic.cmd and setEnv.cmd for Windows systems, and startWebLogic.sh and setEnv.sh for UNIX systems.

• Examples server

  The examples server uses an associated configuration file (config.xml) that defines the attributes for all the example applications in the WebLogic Server distribution. Also provided are the following command scripts for starting the examples server with the examples configuration file and for setting the environment to build and run the examples: startExamplesServer.cmd and setExamplesEnv.cmd for Windows systems, and startExamplesServer.sh and setExamplesEnv.sh for UNIX systems.

• Pet Store server

  The Pet Store server uses an associated configuration file (config.xml) that defines the attributes required for the Pet Store application. (The Pet Store application is provided in the WebLogic Server Tour to demonstrate the capabilities of the J2EE platform and WebLogic Server.) Also provided are the following command scripts for starting the Pet Store server with the Pet Store configuration file: startPetStore.cmd for Windows systems, and startPetStore.sh for UNIX systems.

Starting the Default, Examples, and Pet Store Servers

The following sections provide procedures for starting the default server, the examples server, and the Pet Store server on a Windows or UNIX system. The procedure for starting the Pet Store server also includes the procedure for starting the Pet Store application on the Pet Store server.

• Starting the Default Server on a Windows System

• Starting the Default Server on a UNIX System

• Starting the Examples Server on a Windows System

• Starting the Examples Server on a UNIX System

• Starting the Pet Store Server and Application on a Windows System

• Starting the Pet Store Server and Application on a UNIX System

You cannot run these servers concurrently because they are configured to share the same ports that you entered in the Default Server Configuration window during the installation (by default, port 7001 for non-secure connections, and 7002 for SSL connections). However, you can change a server's port configurations by editing the server's start command script and specifying the following Java command-line options:

• -Dweblogic.ListenPort=your_non-secure_port_number

• -Dweblogic.SSL.ListenPort=your_SSL_port_number

In the following listing, for example, the added Java command-line options highlighted in bold will change the examples server port configurations to 7005 (non-secure) and 7006 (SSL). These values become the run-time listen port values when you use the modified startExamplesServer.cmd/sh script to start the examples server, and the listen port values stored in the examples server config.xml file are ignored.

Listing 7-1 Modified startExamplesServer.cmd Script

.
.
.
"%JAVA_HOME%\bin\java" -hotspot -ms64m -mx64m -classpath 
    %CLASSPATH% -Dweblogic.Domain=examples 
    -Dweblogic.Name=examplesServer -Dbea.home="C:\bea" 
    -Dcloudscape.system.home=./samples/eval/cloudscape/data 
    -Djava.security.policy=="C:\bea\wlserver6.1/lib/weblogic.policy"
    -Dweblogic.ListenPort=7005 -Dweblogic.SSL.ListenPort=7006
    weblogic.Server
goto finish

:finish
cd config\examples
ENDLOCAL

The default, examples, and Pet Store servers all run under the system identity, which is the system account created during the WebLogic Server installation. As of WebLogic Server version 6.1, the system password for all three servers is the password that you specified during the installation. Although no password.ini files are included in the WebLogic Server 6.1 installation, WebLogic Server still supports the use of password.ini files for the examples and Pet Store servers.

After starting the default, examples, or Pet Store server, you can start the Administration Console to monitor the server and any application that the server is running. The Administration Console is the Web-based administrator front-end (administrator client interface) to WebLogic Server.

Bear in mind that HTTP tunneling is disabled by default for all servers. As a result, all WebLogic Java-based clients will fail to connect to the server over HTTP and HTTPS (HTTP using SSL). For example, if you run a Java-based client example (such as examples.ejb.basic.statelessSession) over HTTP/HTTPS, the example fails. Browser-based clients are not affected by this configuration because they do not use HTTP tunneling. To resolve this issue, you must enable HTTP tunneling. For information about how to enable HTTP tunneling, see "Configuring WebLogic Server Web Components" in the Administration Guide.

Uninstalling WebLogic Server

Uninstalling WebLogic Server does not remove the BEA Home directory associated with the installation but does remove all WebLogic Server components installed by the installer program. The uninstallation also removes the product directory associated with the installation unless one of the following is true:

• The product directory contains customer-created configuration or application files—the uninstallation does not delete customer-created configuration or application files.

• The uninstall was invoked from within the product directory structure—specifically, within the uninstaller directory.

If the WebLogic Server installation was upgraded with a Service Pack at the customer site, you must uninstall the Service Pack before uninstalling WebLogic Server. For information about uninstalling Service Packs, see Uninstalling a Service Pack.

To uninstall WebLogic Server, complete the procedures for the appropriate platform, provided in the following table.

Reinstalling WebLogic Server

When you start the BEA Installation program on a system on which a copy of WebLogic Server 6.1 is already installed, the BEA Installation program detects the existing installation and provides you with the prompts shown in the following table.

Click . . .	To . . .
Cancel	Return to the Choose BEA Home Directory window. You cannot install multiple copies of WebLogic Server 6.1 having the same BEA Home directory. To continue installing the software using a different BEA Home directory, select an existing BEA Home directory that does not contain a WebLogic Server installation or create a new BEA Home directory.
Exit	Exit the installation program and uninstall the previous installation. You can invoke the uninstall program as described in Uninstalling WebLogic Server, and reinstall the software as described in one of the following: Installing WebLogic Server Using GUI-Mode Installation Installing WebLogic Server on UNIX Systems Using Console-Mode Installation Installing WebLogic Server Using Silent Installation

 

As of WebLogic Server version 6.1, you are not allowed to reinstall WebLogic Server over a previous WebLogic Server 6.0 or 6.1 installation. To reinstall WebLogic Server, you must first uninstall the previous installation.

Note About Machine Names When Resinstalling WebLogic Server

If you reinstall WebLogic Server 6.1 on a machine after uninstalling it, the installation program checks the primary name of the machine and compares it to the name of the machine in the registry.xml file. If the names do not match (for example, if you changed the primary name of the machine), the installation will fail. As a work-around, you can update the machine name in the registry.xml file.

The installation program expects the format of the machine name to be the value returned by the following Java method:

InetAddress.getLocalHost().getHostName()

You can write a short Java program that uses this method to get the machine name in the proper format to update the registry.xml file.
