Manage application servers
We can use either the administrative console or command line tools to manage your application servers.
About this task
Important: If you are migrating from a previous version of WebSphere Application Server, we can upgrade a portion of the nodes in a cell, while leaving others at the older release level. This means that, for a period of time, you might be managing servers that are running at different release levels in the same cell. In this mixed environment, there are some restrictions on what we can do with servers that are running the older release level. There are no restrictions on what we can do with the servers that are running on the newer release level.We can perform the following steps to view and manage an application server from the administrative console.
Procedure
- In the administrative console click Servers > Application servers. The Application servers page lists the application servers in your environment and the status of each of these servers. We can use this page to change the status of a listed application server.
- Click the name of a listed application server to view or change the configuration settings for that application server.
- Save any configuration changes that you make.
- Start the application server, or stop and restart the application server if it is already running.
- Monitor running application servers.
- Stop an application server.
- Delete an application server.
Tip: If the server you are deleting has applications or modules mapped to it, remap the modules to another server, or create a new server and remap the modules to the new server, before deleting the old server. After a server to which modules are mapped is deleted, we cannot remap these modules to another server. Therefore, if you do not remap the modules to another server before deleting the old one, uninstall all of the modules that were mapped to the old server, and then reinstall them on a different server.
- In the administrative console, click Servers > Application servers to access the Application Servers page.
- Select an application server to delete.
- Click Delete.
- Click OK to confirm the deletion.
Results
Your configuration changes appear when you click Servers > Application servers > server_name in the administrative console. We can also click Servers > Application servers to verify that each server is in the appropriate start or stop state.
What to do next
- We can make additional configuration changes.
- We can create additional application server as required.
- We can deploy applications or components to your application servers.
