Installer		Platform specific installers are avialable	From 12.1.2, there is only generic installer available
JDK		JDK 6 and 7 supported	JDK  7 supported
		JDK bundled with 32bit installers	JDK needs to be installed specifically
Web server Plugin		Webserver plugin is bundled with WLS installer	Plugins need to be downloaded from Oracle support
Patching		bsu/smart update to apply patches	java-based utility Opatch is introduced
Upgrade Features		Domain upgrade wizard or rolling upgrade is used	Reconfiguration Wizard is newly introduced
			Domains on remote machines can be upgraded using the WLST writeTemplate command
New Configuration Features	Configuration Wizard	Configuration wizard has same features in all 11g versions	Support has been added for configuring OHS
			A Template Categories drop-down list has been added
			Node Manager configuration options have been changed and expanded

	Template Location	WL_HOME/common/templates/applications andWL_HOME/common/templates/domains	WL_HOME/common/templates/wls
	Quick Start Configuration Wizard	same config wizard is used	new utility called the Quick Start Configuration Wizard
	Node Manager Configuration	Multiple domains in same machine can share same NM process	Domain specific NM is created
Cluster	Dynamic Clusters	Static clusters	Dynamic clusters allow you to easily scale up the number of server instances
	Cluster Targeted JMS Servers	-	Targeting JMS Servers and persistent stores directly to a cluster
Oracle Database 12c Integration		ONS list is required	With WLS 12.1.2 one does not require the ONS Listener list as part of an Active GridLink datasource configuration
Additional Component-Level Features and Changes	Deployment	-	An application’s deployment plan can be staged independently of the application archive, allowing you to stage a deployment plan when the application is not staged

			Pinned-to-thread Support for GridLink Data Sources
			Using GridLink Data Sources without Fan Notification
			Set Identity and/or Client Identifier as WebLogic User
			Connection Testing Improvements
			JavaDB Support
			Maintenance Timer Improvements
	pack and unpack Utilities	All domain data is included in template	Persistent file stores are no longer included in a packed domain
		No node manager configuration preserved	Node Manager configuration is preserved by pack and unpack
Security	SSL Implementation	Versions prior to 10.3.4 support certicom whereas later versions support both certicom and JSSE	Only JSSE will be supported
	Oracle OPSS Keystore Service Support	JKS supported	OPSS Keystore Service provides an alternate mechanism to manage keys and certificates
	Location of demo identity	WL_HOME/server/lib	DOMAIN_HOME/security
WebLogic Diagnostic Framework	Built-in System Diagnostic Modules	No built-in modules	WLDF adds a set of built-in system diagnostic modules
	Targeting Multiple Diagnostic Modules to a Server or Cluster	target only one diagnostic system module to a server or cluster	target multiple diagnostic system modules to a server or cluster
	Dynamic Activation/Deactivation of Diagnostic System Modules	No dynamic activation available	The ability to dynamically activate and deactivate diagnostic system modules that are defined in the domain configuration
			The ability to create and activate a diagnostic system module on-the-fly that is not defined in the domain configuration
	New Diagnostics WLST Commands		listSystemResourceControls(), enableSystemResource(), disableSystemResource(), createSystemResourceControl(), destroySystemResourceControl(),dumpDiagnosticData()
WLST		WLST commands are same across all minor versions	Various WLST commands are newly added for eg:
			readDomainForUpgrade opens an existing domain for reconfiguration.
			getNodeManagerHome returns the path of the Node Manager home directory.
			getNodeManagerType returns the Node Manger type.
			clone clones an existing Managed Server to create a new Managed Server.
			listSystemResourceControls()lists all available diagnostic system modules.
			enableSystemResource() activates a diagnostic system module.
			disableSystemResource() deactivates a diagnostic system module.
			createSystemResourceControl() creates a diagnostics system module on-the-fly using a specified descriptor file.
			destroySystemResourceControl() destroys a diagnostics system module previously created on-the-fly.
			dumpDiagnosticData() dumps the diagnostics data from a harvester to a local file.
Deprecated Functionality		The use of “BEA” as the naming prefix in error messages and log messages.	weblogic.management.username and weblogic.management.password is deprecated in WLS 12c
