• Newer version of application deployed side-
by-side with older version in same JVM
• Clients already connected continued to be
served by older version
• New clients connect to newer version
• Test versions before opening up to users
• Rollback to previous versions
• Automatic retirement – graceful or timeout

• Unzip the ZIP file
• Go to the extracted folder using your terminal
• Make sure JAVA_HOME points to a Oracle JDK 1.7 installation directory
• Execute the configure utility
– Windows: configure.cmd
– Unix (Mac/Linux): configure.sh
• By the end, it will ask you if you want to create a domain. Say ‘Y’.
• Provide a username and password of your choice
• WebLogic will then start and be accessible from http://localhost:7001/console
