Weblogic Deployment Staging Modes


Deployment applications and modules (which has been organized according to the J2EE specification) may include Java classes for EJBs and servlets, resource adapters, Web pages and supporting files such as XML-formatted deployment descriptors can be deployed to Weblogic server.

You can deploy, redeploy, undeploy, and distribute applications using Weblogic server Administration Console and weblogic.Deplopyer.

You can deploy an application as a single archive EAR file or as an exploded archive directory.

WebLogic Server provides three different options for deployment files:

Nostage mode: The Administration Server does not copy the deployment unit files to the target servers. The deployment units are deployed directly from the source. This mode is useful when deploying very large deployments to multiple targets. This is the default staging mode for the Administration Server.

Stage mode: The Administration Server copies the deployment unit files to the staging directories of target servers and they are deployed using the local copy. This mode is useful when deploying small size applications. This is the default staging mode for Managed Servers.

External mode: In this mode you manually  copy the deployment units  to the staging directories and then deploy.

Note: If you wish to deploy an application or module with in external stage mode, use the weblogic.Deployer utility.
