Introduction to the WebLogic Server 12c on OSX

In order to assess the work considering automation of configuration and deployment for one of our back-end applications, I needed to install WebLogic 12g locally. So, I decided to share this with the rest of the community. Hope you enjoy this quick demonstration.

Prerequisites

• Download and unzip the Quick Installer for Mac OSX, Windows, and Linux from the Oracle Website. 
• Assure you have installed the Oracle JDK 1.8

Installation

In this article, I will install the server under ~/Opt/Oracle/WebLogic/Middleware; make sure the root directory structure exists before moving to the following step.

# Which JREs have been installed?
$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.0_192, x86_64:  "Amazon Corretto 8" /Library/Java/JavaVirtualMachines/amazon-corretto-8.jdk/Contents/Home
    1.8.0_181, x86_64:  "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home

# Set Java home to Java SE 8...
$ export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_181`

# Set WebLogic home
$ export MW_HOME=~/Opt/Oracle/WebLogic/Middleware

Next, kick off the installation itself:

# Kick-off the installation
$ (cd $MW_HOME && java -jar /path/to/fmw_12.2.1.3.0_wls_quick.jar)

Configuration

Some minor configuration requires to be done after installation.

# Set memory of admin server
export USER_MEM_ARGS="-Xmx1024m -XX:MaxPermSize=256m"

# Read the Weblogic server path settings
$ . $MW_HOME/wls12213/wlserver/server/bin/setWLSenv.sh

Startup Admin Server

Start WebLogic Server for the first time and create a domain.

# Create domain dir
$ cd $MW_HOME/../
$ mkdir domain

# Inside the domain dir start the Admin server
$ cd domain
$ java -Xmx1024m -XX:MaxPermSize=256m weblogic.Server

WebLogic will notice this is the first time it has been started and will ask you if you want to create a domain. Answer ‘y’ to this question, and then provide a username and password when requested.

Would you like the server to create a default configuration and boot? (y/n): y
Enter username to boot WebLogic server: admin
Enter password to boot WebLogic server: P@ssw0rd
For confirmation, please re-enter password required to boot WebLogic server: P@ssw0rd

WebLogic Server will start up. When it is up, you will see a message indicating that the server was started in RUNNING mode. Once you see this, you can shut it down (type Ctrl-C).

You can now use the startup scripts in your newly created domain. When you want to start WebLogic Server, enter the following commands (you might want to create a script to do this):

export JAVA_HOME=`/usr/libexec/java_home -v 1.8.0_181`
export MW_HOME=~/Opt/Oracle/WebLogic/Middleware
export USER_MEM_ARGS="-Xmx1024m -XX:MaxPermSize=256m"
. $MW_HOME/wls12213/wlserver/server/bin/setWLSenv.sh
$MW_HOME/../domain/startWebLogic.sh

Console

You can now log on to the WebLogic Server console at http://localhost:7001/console.
