WebLogic Server 12cR1 (12.1.2 and 12.1.3) : Create, Extend and Remove Domains

This article provides a quick overview of managing domains in WebLogic Server 12c. The examples all relate to WebLogic 12.1.2 and 12.1.3. If you are using WebLogic 12.1.1, you should probably refer to this article.

Create a Domain

Start the Configuration Wizard.

$ $WLS_HOME/common/bin/config.sh

Accept the "Create a new WebLogic domain" option and enter the domain location, including the domain name at the end of the location. In this case I used "/u01/app/oracle/config/domains/testDomain". Click the the "Next" button.

Configuration Type

Select the templates the domain requires and click the "Next" button. Depending on the options you pick, a number of additional steps may be included.


Enter the application location, including the domain name in the path, and click the "Next" button.

Application Location

Enter the administor account credentials and click the "Next" button.

Administrator Account

Enter the domain mode and JDK, then click the "Next" button.

Domain Mode and JDK

Select the "RCU Data" option and enter the database details. Click the "Get RCU Configuration" button.

Database Configuration Type

Once the details are retrieved, click the "Next" button.

Database Configuration Type

Accept the component datasources by clicking the "Next" button.

Component Datasources

Once the JDBC tests have completed successfully, click the "Next" button.


Select the advanced configuraton options you require and click the "Next" button. For this example I just configured the Node Manager. Depending on the options you pick, extra steps may be added.

Advanced Configuration

Select the type of node manager you require and enter the credentials. Click the "Next" button.

Node Manager

If you are happy with the summary information, click the "Create" button.


Once the configuration is complete click the "Next" button.

Configuration Progress

Make a note of the Admin Server URL and click the "Finish" button.

Configuration Success

The following scripts are created for the "testDomain" domain. You will need to create a Boot Identity File if you want to use the "&" to start the domain or and managed servers as background processes.

$ # Set the domain home
$ export DOMAIN_HOME=$ORACLE_BASE/config/domains/testDomain

$ # Start NodeManager
$ nohup $DOMAIN_HOME/bin/startNodeManager.sh > /dev/null 2>&1 &

$ # Start WebLogic
$ nohup $DOMAIN_HOME/startWebLogic.sh > /dev/null 2>&1 &
$ # or
$ nohup $DOMAIN_HOME/bin/startWebLogic.sh > /dev/null 2>&1 &

$ # Stop WebLogic
$ $DOMAIN_HOME/bin/stopWebLogic.sh

$ # Start Managed Server
$ nohup $DOMAIN_HOME/bin/startManagedWebLogic.sh AdminServer > /dev/null 2>&1 &

$ # Stop Managed Server
$ $DOMAIN_HOME//bin/stopManagedWebLogic.sh AdminServer

Once the domain is started, the administration console is available in a browser using a URL such as "http://machine:7001/console".

Update a Domain

Updating a domain involves similar screens to those seen during the installation.

Delete a Domain

To remove the "testDomain" domain we just created, do the following steps:

Creating a Boot Identity File

When running in production mode, starting a server requires the credentials you provided while creating the domain. Using a boot identity file prevents you from having to type in the username/password each time the server is started.

Create a file called "boot.properties" with the following contents.


Save the file under the "$DOMAIN_HOME/servers/<server-name>/security" directory. The managed server will now start and stop without needing credentials. This should be done for the AdminServer, as well as all managed servers.

Alternatively, modify the JAVA_OPTIONS in the "setDomainEnv.sh" file to point to the location of the file. For example, if the "boot.properties" file is in the domain's home directory, you could place the following lines after the DOMAIN_HOME definition. This method works fine for startup, but shutdown will still require credentials, so it is not as convenient.

JAVA_OPTIONS="${JAVA_OPTIONS} -Dweblogic.system.BootIdentityFile=${DOMAIN_HOME}/boot.properties"

The first time the server starts using a boot identity file, it will encrypt the credentials in the file and use them when starting in future.

Altering Server Port Settings

When you create a domain you will automatically create an AdminServer that listens on port 7001 by default. To change this, edit the "$DOMAIN_HOME/config/config.xml" file, adding or amending the "listen-port" entry, shown in bold.


Switching Development/Production Startup Mode

There are two locations where the startup mode can be set. If you are using the Java based controls the mode is picked up from the "$DOMAIN_HOME/config/config.xml" file. Set the "production-mode-enabled" tag to the appropriate value.


If you are starting the domain using the generated startup scripts, you should edit the "$DOMAIN_HOME/bin/setDomainEnv.sh" file. Set the "PRODUCTION_MODE" parameter to the appropriate value.


To prevent confusion, it makes sense to keep both files set to the same value.
