Oracle WebLogic Server 12c: Installing WebLogic Server and Creating a Domain

Overview

    Purpose

    This tutorial shows you how to install Oracle WebLogic Server 12c and create a WebLogic Server domain.

    Time to Complete

    Approximately 1 hour

    Introduction

    This tutorial shows you how to install Oracle WebLogic Server 12c (12.1.3) on a Linux system by using the generic installer. The generic installer requires a Java Developers Kit (JDK), so this tutorial first covers installing the JDK. After you install the JDK and WebLogic Server, this tutorial shows you how to use the Configuration Wizard to create a WebLogic Server domain.

    Hardware and Software Requirements

    The only requirement is that your operating system must be Oracle Linux 5.6+.

    Prerequisites

    Before starting this tutorial, download the following to your Linux machine:

    • Oracle Java Developers Kit version 1.7.0_55+
    • Oracle WebLogic Server 12c (12.1.3) generic installer (includes Oracle Coherence)

Installing the JDK

    To install the JDK, perform the following steps:

    Extract the JDK to a directory of your choice.

    1. Open a Terminal window and navigate to the directory where you want to install the JDK. For example, to navigate to the /scratch/u01/app directory, enter the following command:

      $> cd /scratch/u01/app

    2. Copy (or move) the JDK file from the directory where you downloaded it to the current directory. In this tutorial, the JDK is in the /scratch/install/jdk directory. To copy the JDK file from there into the current directory, enter the following command:

      $> cp /scratch/install/jdk/jdk-7u60-linux-x64.gz -t .

      Note: The name and location of your JDK file may be different.

    3. Unpack the file by using the tar command:

      $> tar -zxvf jdk-7u60-linux-x64.gz

      The tar options are:

      • z: unzip
      • x: extract
      • v: verbose
      • f: filename

    (Optional) Rename the JDK directory. To make the directory name more generic, use the mv command to rename it jdk.

    $> mv jdk1.7.0_60 jdk

    Note: The name of your JDK directory may be different.

    Use the rm command to erase the copied JDK file.

    $> rm jdk-7u60-linux-x64.gz

    Note: The name of your JDK file may be different.

Installing WebLogic Server

    To install WebLogic Server, perform the following steps:

    Run the generic installation program (the JAR file).

    1. Open a Terminal window and navigate to the bin directory under the JDK directory.

      $> cd /scratch/u01/app/jdk/bin

    2. Run the Java virtual machine with the -jar option, calling the generic installer JAR file that you already downloaded. In this tutorial, the JAR file is in the /scratch/install/wls12.1.3 directory. The file name is fmw_12.1.3.0.0_wls.jar.

      $> ./java -jar /scratch/install/wls12.1.3/fmw_12.1.3.0.0_wls.jar

      Note: The name and location of your generic installer JAR file may be different.

    After the installer extracts files, it analyzes your system to see if it meets the minimum requirements (CPU speed, for example). If everything checks out, the graphical Oracle Universal Installer starts.

    On the Welcome screen of the installer, click Next.

    On the Installation Location screen, enter the location for Oracle Home (or click Browse to browse to the location), and then click Next.

    In this demonstration, Oracle Home is /scratch/u01/app/fmw.

    On the Installation Type screen, select either WebLogic Server (it includes Coherence) or Complete with Examples, and then click Next.

    In this demonstration, the selection is WebLogic Server.

    On the Prerequisite Checks screen, wait for all checks to complete successfully, and then click Next.

    On the Security Updates screen, perform the following steps:

    1. Enter your email address.
    2. Select I wish to receive security updates via My Oracle Support.
    3. Enter your My Oracle Support password.
    4. Click Next.

    Note: If the machine on which you are installing WebLogic Server is part of a training environment, deselect I wish to receive security updates via My Oracle Support, and click Next. In the dialog box that opens, click Yes.

    On the Installation Summary screen, review the installation information. If everything is acceptable, click Install.

    On the Installation Progress screen, wait for the progress bar to reach 100%, and then click Next.

    On the Installation Complete screen, deselect Automatically Launch the Configuration Wizard, and then click Finish.

    Close the Terminal window that you used to launch the installer.
