Steps to DeInstall Oracle Weblogic Server 12.1.2.0.0...

How to DeInstall Oracle Weblogic Server 12.1.2.0.0 ? 

- Oracle Weblogic Server 12.1.2 can be Deinstalled in two ways :

* GUI mode

* Silent Mode 

- For GUI mode go to " ORACLE_HOME\oui\bin " directory and run deinstall script.

- For Silent mode use the following command :

Go to " ORACLE_HOME\oui\bin " directory

./deinstall.sh -silent -response <deinstaller_response_file> 

- The deinstaller does not remove the JDK or any user-created data such as WebLogic domains or custom application data. Only the components that were installed by the installation program are removed by the deinstaller. 

- Make sure you have stopped all the servers / processes running before starting the DeInstaller.

Steps to create a new domain on Weblogic Server 12.1.2.0.0...

Weblogic Server Domain Configuration Wizard - Points to remember :

- Adding " -Djava.security.egd=file:/dev/urandom " in Unix/Linux decreases the amount of time it takes for the Configuration Wizard to create or update a domain.

- Quick Start Configuration Wizard can be used only to configure the various sample domains, such as MedRec and the Examples Server, in your WebLogic Server installation.

- You can start Quick Start Configuration Wizard in two ways :

1. Select the Automatically Launch Quick Start Configuration Wizard option on the Installation Complete screen of the WebLogic Server installer.

2. Run the config.cmd / config.sh script located in ORACLE_HOME/oracle_common/common/bin as follows : " config.cmd -target=config-oneclick " in windows and " config.sh -target=config-oneclick " in Linux.

- Prior to manually running the Configuration Wizard in Quick Start mode, you must set the CONFIG_JVM_ARGS environment variable to specify the full path and JAR file name for each template that you want to use for the domain.

- To set CONFIG_JVM_ARGS on a Windows system:

set CONFIG_JVM_ARGS="-DuserTemplates=C:/Oracle/Middleware/wlserver/common/
templates/wls/wls.jar,C:/Oracle/Middleware/wlserver/common/templates/
wls/wls_webservice_jaxws.jar"

- To set CONFIG_JVM_ARGS on a UNIX:

export CONFIG_JVM_ARGS="-DuserTemplates=/Oracle/Middleware/wlserver/common/
templates/wls/wls.jar,/Oracle/Middleware/wlserver/common/templates/
wls/wls_webservice_jaxws.jar"

- Domain can be created using GUI mode or using WLST.

- There is silent mode installation only for WLS 12.1.2 installation and not for WLS 12.1.2 domain creation.

- Nodemanager can now be configured in domain configuration wizard.

In this post we will see how to create a new Weblogic Server domain using DomainConfigurationWizard.
