A WebLogic cluster can also be added to the domain. The cluster consists of one or
more Managed Servers acting as one single entity. A single WebLogic Server installation
is not restricted to one WebLogic domain, and more domains can be created using the
same installation.
Getting ready
Before creating a new WebLogic domain, you have to plan and define its architecture.
For production environments, it is mandatory to use WebLogic clusters with a minimum
architecture of at least two WebLogic Server instances (the Managed Servers) in two
different machines. The objective is to avoid having a single point of failure.
We will create a new WebLogic domain called PROD_DOMAIN with an administration instance
( AdminServer ) named PROD_AdminServer and a WebLogic cluster PROD_Cluster with
the two Managed Servers PROD_Server01 and PROD_Server02 . The two machines hosts
are called prod01 and prod02 . Since you have already installed WebLogic Server 12 c in
prod01 , install it in prod02 as well. We will assume these names throughout the entire topic.
The machines prod01 and prod02 should also have IP addresses assigned and be visible
through the network. It's recommended to use the fully qualified domain name (FQDN) of the
servers. In this recipe, and the rest of the topic, prod01 is prod01.domain.local and the
hostname of the prod02 machine is prod02.domain.local .
To simplify the reading, we'll use the following term when referring to the
directories:
$DOMAIN_HOME to the created WebLogic Domain directory— /oracle/
Middleware/user_projects/domains/PROD_DOMAIN .
How to do it...
To create a new WebLogic domain, follow the ensuing steps:
1. Log in as a wls user on the first machine prod01 and navigate to the following folder:
[wls@prod01]$ cd $WL_HOME/common/bin
2. Start WebLogic Configuration Wizard in console mode:
[wls@prod01]$ ./config.sh -mode=console
3. Follow the onscreen instructions and type 1 , and press Enter to select the Create
a new WebLogic domain option on the Welcome screen.
4. Type 1 and press Enter to select the Choose WebLogic Platform components option
on the Select Domain Source screen.
