Basic difference of WLS 11G and WLS 12C


Component WLS 11g WLS 12c

Installer Platform specific installers are available Only generic installer available

JDK JDK 6 and 7 supported JDK 7 supported

JDK bundled with 32bit installers Seperately we need to install JDK

Web server Plugin Webserver plugin is bundled with WLS installerPlugins need to be downloaded from Oracle support

Patchingbsu/opatch/smart update

Smart update removed.BSU & Opatch is available to patchWebLogic Server and for Oracle Fusion Middleware.

Opatch Version 11.1.0.0 $ORACLE_HOME/oracle_common/Opatch

Oracle Fusion Middleware 12c (12.1.3) includes OPatch Version 13.2.0.0.0 under $ORACLE_HOME/OPatch directory

Upgrade Features Domain upgrade wizard Reconfig Wizard

Node Manager ConfigurationMultiple domains in same machine can share same NM process Domain specific NM is created

Dynamic Clusters Static clustersDynamic clusters allow you to easily scale up the number of server instances

Active GridLink ONS list is requiredDoes not require the ONS Listener list as part of an Active GridLink datasource configuration

Dynamic Clusters & Server TemplatesScale Clusters by Changing one Parameter

• Create cluster based on server template• Rules for calculating server-specific attributes

– Server name, listen ports, machines

• # of servers can be dynamically changed• Building block for elasticity• Whole server migration supported• Auto-scaling coming soon [12.1.4]

– Elastic Clusters

Exalogic Storage

Application

• Problem: Maximize JMS message processing performance on Exalogic

• Solution: Compress JMS messages to optimize I/O intensive processing

• Benefit: Up to 3X throughput increase for JMS workloads requiring message persistence


Elastic JMS

• Cluster-targeted JMS Servers• Cluster-targeted JMS Stores• Benefits

– JMS enabled on Dynamic Clusters– Simplified scalability– Much simpler subdeployments– Configured clusters supported as well

– Restriction in JMS:No Unit Of Order & Work

1) What all application is currently moved to Weblogic 12c and What Version is installed.

Transport-EXT,INT on 12.1.1.0.8 & JAVADL on 12.1.3.0.02) Was it upgraded from 11g to 12c? No, directly moved to WLS 12C3) Is there any change in Patching mechanism in Weblogic 12c – No Changes to Patch mechanism. No BSU Utility 4) Any Major change in AC/ deployment strategy. No major/minor changes

FAQ

13


Faq Cont..5) Are there useful benefit of WLS 12C being used in Transport. Major benefits with JAVA 7 and WLS 12c as it addresses many bugs for

huge file size handling6) Any changes in EM level monitoring? No major change in EM monitoring except that FMW control is

difficult to include because of the need to have DB schema. 7) Anything addition done to accommodate in Weblogic 12c- Nothing much additional except java7 usage. Also OHS registration with

Weblogic Farm(/em) is an issue because of #6



Faq Cont..8) Dependencies to check before migrating your WebApp to WLS 12C.
