In this Fusion Middleware training article, you will learn the steps for upgrading Weblogic Domain
— The first phase is to upgrade the application environment using the WebLogic Upgrade Wizard.+
— In the next phase we adopt our build and deployment process.
— We could manually build and run our application under WebLogic Server 11g.
— The upgradation to WebLogic 11g was first done in the development environment.
— After completing the upgrade to the development environment and executing quality assurance procedures, we promoted the upgraded environment to the production environment.
The following are the steps involved in upgrading an application environment:
— Step 1: Plan the Upgrade
— Step 2: Prepare to Upgrade
— Step 3: Upgrade Your Application Environment
— Step 4: Complete post-upgrade procedure
Step 1: Plan the Upgrade
— Perform inventory on an existing environment
— Verify support configuration for all hardware and software components
— Review the compatibility information
— Create an upgrade plan by identifying the scope and
Timing of the upgrade process based on the business needs
Step 2: Prepare to Upgrade
— Un-deploy all applications and shut down all servers
— Back up the application environment
— Install a new version of WebLogic Server 11g
— Copy the Old WebLogic domain to the WebLogic 11g "domains" directory
— Set up the environment - Classpath, Path, WebLogic Home, and third-party libraries
Step 3: Upgrade Your Application Environment
— Upgrade custom security providers: If you are upgrading from WebLogic Server 7.0 or 8.1, and you have custom security providers in your current application environment that you wish to continue using in the new environment, upgrade them on all machines in the environment before you upgrade the WebLogic domain.
— Upgrade Node Managers: If you are currently using a customized version of Node Manager and you wish to continue doing so in the new application environment, upgrade all the Node Managers on all machines in the environment.
— Upgrade WebLogic domain (Administration Server): Upgrade the WebLogic domain on the machine that hosts the Administration Server. Note: Oracle recommends that you upgrade Administration Server for a domain before the Managed Servers.
— Upgrade WebLogic domain (remote Managed Servers): Upgrade the WebLogic domain on every machine that hosts any managed servers. Be sure to copy the appropriate files to the managed servers before performing the upgrade.
Step 4: Complete post-upgrade procedure
— Re-apply customizations to startup scripts
— Verify file permissions
— Enroll the machine with node manager
— Verify remote server startup options
— Promote the Application Environment to Production
