You can use either the administrative console or command line tools
to manage your application servers.
Before you begin
If
you plan to change the system clock, stop all the application servers, the
node agent servers, and the deployment manager server first. Once you stop
the servers, change the system clock, and then restart the servers. If you
change the system clock on one system, you must ensure the clocks on all systems
that communicate with each other and have WebSphere Application Server installed
are synchronized. Otherwise, you might experience issues, such as security
tokens no longer being valid.
About this task
Important: If
you are migrating from a previous version of WebSphere Application Server,
you 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 you can
do with servers that are running the older release level. There are no restrictions
on what you can do with the servers that are running on the newer release
level.
You 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. You 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, you cannot remap these modules to another server. Therefore,
if you do not remap the modules to another server before deleting the old
one, you must 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. You can also
click Servers > Application servers to verify that each server is in
the appropriate start or stop state.
What to do next
- You can make additional configuration changes.
- You can create additional application server as required.
- You can deploy applications or components to your application servers.
