The Deployment Life Cycle

After installing the Enterprise Server and starting a domain, you can deploy (install) Java EE modules. During deployment and as the application is changed, a module can go through the following stages:

1. Initial Deployment

   Before deploying a module, start the domain.

   Because modules are packaged in archive files, specify the archive file name during deployment.

   Deployment is dynamic: you don’t need to restart the server after deploying a module. If you do restart, all deployed modules are still deployed and available.

2. Enabling or Disabling

   By default, a deployed module is enabled, which means that it is runnable. To prevent access, disable the application or module. A disabled module is not uninstalled from the domain and can be easily enabled after deployment. For more information, see Disabling a Deployed Application or Module.

3. Redeployment

   To replace a deployed module, redeploy it. Redeploying automatically undeploys the previously deployed module and replaces it with the new one.

4. Undeployment

   To uninstall a module, undeploy it.
