Info on Google Chrome with Java 7 on Mac OS X

Fact Check : Guys, did you know the following fact about Chrome : Google Chrome does not work with Java 7 on Mac OS X. Turns out that the 32-bit Chrome browser does not support Oracle Java 7 on Mac OS X.

Folks, please make a note of this, in case you're planning to upgrade Apple supplied Java 6 to Java 7.

Oracle Weblogic 12c Installation Guide on Mac OSX

This post will walk you through the installation of Oracle Weblogic Application Server 12c on a Mac OSX machine.

First of all, visit the official Oracle Weblogic download page and download the latest generic version. You would need to create a Oracle ID first. Accept the agreement and start the download. In this example, we would download the Weblogic v12.1.2. The filename in this case is wls_121200.jar

Also, note that the generic version does not come with JVM / JDK for its installation. So make sure, you have Java installed on your machine.

Once downloaded, note the following steps :

Run the following command to initiate the installer

java -d64 -Dspace.detection=true -Xmx1024m -jar wls_121200.jar

This will start the extraction of the wls_121200.jar and also perform some routine system pre-requisite checks. Note the arguments that we passed. The space.detection parameter is set to true to detect available space. Also, the max memory usage size by JVM is set to 1024m i.e 1 GB.

Now, you'll the following installer GUI screens.

In the next screen, you'll see the option to modify or change location of Oracle_Home directory. Leave it to default option if you don't want to modify the location. Click Next.

In the following screen, you have to choose the type of installation. Choose the default option. However, choosing the Complete Installation will also install OPatch and some examples like medrec. 

In next screen, you can see the overall Installation summary. Save the response file if you intend to perform silent installations in the future. Check this link for reference. Click Next.

This will start the installation process. This will take a few minutes. You can observe the overall progress here.

Once the installation is completed, you'll see the following screen. Click Finish. This will initiate the next step - Configuration Wizard.

Below is the welcome screen of the Wizard.

Following is the first screen of the Configuration Wizard. Here you can set the Weblogic Administrator account and define the Parent domain location. Click Next.

In next screen, you'll see the progress of the domain creation.

Now, in the next and final screen, you'll see the Configuration success scene. Here you can check the option to start domain. Leave it unchecked, so that we can start it manually. Click Finish. That's pretty much a plain vanilla installation of Oracle Weblogic server 12c on Mac OSX machines.

In my next post, I'll cover how to start and stop Weblogic 12c and any associated issues related to it.
