If an application is deployed to multiple targets (stand-alone server instances or clusters), you have two ways of redeploying to multiple targets. Use one of the following methods to make sure all server instances that reference an application receive the most recent version.
In a development environment, simply redeploy the application. The application is redeployed to the domain, and all targets that reference it automatically receive the new version if dynamic reconfiguration is enabled for the target server instances. Dynamic reconfiguration is enabled by default. If dynamic reconfiguration is not enabled for a server instance, it continues to use the old version until the server instance is restarted.
In a production environment, follow the steps detailed in “About Rolling Upgrades.”
