Steps to create partitions in WLS 12.2.1

Below are the steps to create partitions in Weblogic Server 12.2.1 :

Step 1 :

- Create a weblogic domain (say Partition_From_Windows_Domain)

FMW control is the recommended console for Partition management, so it is good to enable it at the time of  domain creation.  

To enable FMW control select "Oracle Enterprise Manager-Restricted JRF - 12.2.1 [em]" template in the configuration wizard, as shown below :

To access FMW control access : http://<host>:<port>/em

NOTE : We will continue using Weblogic Admin console to create partitions in this example.

Partition names : coke-partition and pepsi-partition

Partition specific realms : coke_realm and pepsi_realm

Partition specific Admin Users : coke_admin and pepsi_admin

Virtual Targets for these partitions : coke-vt and pepsi-vt

Partition Specific Resource Groups : coke-rg1 and pepsi-rg1

Step 2 :

Before creating a partition, you need to create a security realm (then create an Admin user inside this realm, say coke_admin and pepsi_admin) and virtual target for this partition :

To create a new security realm :

Login to console -> Security Realms -> new (say 'coke_realm' and 'pepsi_realm') -> "create default providers within this new realm" (check)

Now create a Virtual target :

Login to console -> + Environment -> Virtual Targets -> new (say coke-vt) and target it to Weblogic Server (say Admin Server) -> specify a URI Prefix

Step 3 :

Lets create a partition now :

Login to console -> Domain Partitions -> new (say coke-partition)-> then target it to a Virtual target (say coke-vt) -> select the security realm for this partition from the drop down menu (say coke_realm)

 Step 4 :

Create a Resource Group inside domain partition


 Step 5 : 

Check the Identity Domains of the partitions :

Step 6 :

You can now deploy applications to Global scope / to a resource group of a partition

To access the application deployed to your partition use the following URL :

http://<host>:<port>/coke/Weblogic_SP_sample_App/login.jsp  ==> Try to login with the coke Admin and also test the login using weblogic user.

Perform similar tests with application deployed on pepsi-partition and global scoped deployment.

Steps to configure SAML SSO with ADFS (as IDP) and Weblogic Server (as SP)

Active Directory Federation Services (ADFS) is a software component developed by Microsoft that can be installed on Windows Server operating systems to provide users with single sign-on access to systems and applications located across organizational boundaries.

In this example we are using ADFS 2.0 on Windows Server 2008 R2.

ADFS 2.1 is available on Windows 2012 and ADFS 3.0 on Windows 2012 R2.

AlternateLoginID feature is introduced in Windows Server 2012 R2.

You can download ADFS from the following link : 

Link : http://www.microsoft.com/en-us/download/details.aspx?id=10909  --> " RTW\W2K8R2\amd64\AdfsSetup.exe " for Windows Server 2008 R2.

In this post we will see how to configure Single sign-on (SSO) using SAML where ADFS is used as Identity Provider and Weblogic is used as a Service Provider.

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.

In this post we will see how to DeInstall Oracle Weblogic Server 12.1.2.0.0.

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.

Steps to configure SAML 2.0 with Weblogic Server (using embedded LDAP as a security store - Only for Dev Environment)...

 What is SAML 2.0 ?

Security Assertion Markup Language 2.0 (SAML 2.0) is a version of the SAML standard for exchanging authentication and authorization data between security domains.


SAML 2.0 is an XML-based protocol that uses security tokens containing assertions to pass information about a principal (usually an end user) between a SAML authority, that is an identity provider, and a SAML consumer, that is a service provider

It enables cross-platform authentication between Web applications or Web services running in a WebLogic domain and Web browsers or other HTTP clients.

When users are authenticated at one site that participates in a single sign-on (SSO) configuration, they are automatically authenticated at other sites in the SSO configuration and do not need to log in separately.

One who generated the SAML token is called the Identity Provider OR Asserting Party OR Source Site.

And the one accepts the token is called the Service Provider OR Relying Party OR Destination Site.
Trust has to be established between them for SAML to work hence details of the Service Provider has to be with the Identity Provider and details of Identity Provider has to be with the Service Provider.

SAML can be classified into two types depending on the manner in which requests are obtained.

- IDP initiated ( Identity Provider Initiated )

- SP initiated ( Service Provider initiated )

In this post we will see how to configure Single sign-on (SSO) using SAML 2.0 in Weblogic Server.
