WebLogic Server Deployment Modes

Staging Modes in WebLogic Server

Stage mode

The Administration Server copies the archive files from their source location to a location on each of the targeted Managed Servers that deploy the archive. Consider if you deploy a J2EE Application to three servers in a cluster, the Administration Server copies the application archive files to each of the three servers. Each server then deploys the J2EE Application using its local copy of the archive files.

* Stage mode is the default mode when deploying to more than one WebLogic Server instance.

External Stage mode

External stage mode is similar to stage mode, but in that the deployment files must reside locally to each targeted server. Here Administration Server does not automatically copy the deployment files to targeted servers in external stage mode, instead we must manually copy the files, or use a third-party application to copy the files for you.

NoStage mode

The Administration Server does not copy the archive files from their source location. Instead, each targeted server must access the archive files from a single source directory for deployment. If you deploy a J2EE Application to three servers in a cluster, each server must be able to access the same application archive files (from a shared or network-mounted directory) to deploy the application.

* Nostage mode is the default mode when deploying only to the Administration Server (for example, in a single-server domain). You can also select nostage mode if you run a cluster of server instances on the same machine.
