You can use either the administrative console or command-line tools to manage your
application servers.

如果您打算變更系統時鐘,請先停止所有應用程式伺服器、節點代理程式伺服器、部署管理程式伺服器、管理代理程式伺服器,以及工作管理程式伺服器。停止伺服器之後,請變更系統時鐘,然後重新啟動伺服器。如果您變更一個系統的系統時鐘,必須確定所有彼此通訊且安裝了 WebSphere® Application Server 的系統,其時鐘都已經同步。否則,可能會發生錯誤,如安全記號不再有效。

If an application server is running on an operating system when the time zone
setting for the operating system is updated, the application server updates its internal time stamp.
Because of a delay between the change for the time zone and the change to the application server
internal time stamp, an incorrect time stamp could be posted for a file if the file is touched
during this delay. The delay could be several seconds. If the file is part of an application, this
incorrect time stamp would cause the application to stop and then restart because the application
server thinks that the application has been updated.
About this task
transition: If you are migrating from a previous
version of the product, you can upgrade a portion of the nodes in a cell, while leaving others at
the previous 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, some
restrictions exist for what you can do with servers that are running at a previous release level. No
restrictions exist for what you can do with the servers that are running on the newest 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 .
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 complete the following actions:
- Create additional servers.
- Monitor running servers.
- Control the status of a server.
- Create a server template
- Delete a server. When you select a server for deletion, you must click Delete and
OK before the server is deleted.
Tip: If the server you are deleting has
applications or modules mapped to it and is not part of a cluster, remap the modules to another
server, or create a new server and remap the modules to the new server, before you delete this
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 you delete this
server, you must uninstall all of the modules that were mapped to this server, and then reinstall
them on a different server.
If the server you are deleting is part of a cluster,
any application that is installed on this server is automatically installed on all of the other
servers in the cluster. Therefore, deleting one cluster member does not affect the other cluster
members, and the application remains installed in the cluster. Similarly when a new member is added
to an existing cluster, any applications that are installed on the servers in that cluster are
automatically installed on the new cluster member.
- Click the name of a listed server to view or change the configuration settings for that
server.
You can use this administrative console page to:
- Change the configuration settings for the selected server.
For example, if you do not need to
have all of the sever components start during the server startup process, you might want to select
Start components as needed, which is not automatically selected when a new server is created.
When this property is selected, server components are dynamically started as they are needed. When
this property is not selected, all of the server components are started during the startup process.
Therefore, selecting this property usually results in improved startup time because fewer components
are started during the startup process.
- View the status of applications running on the selected server. To view the status of
applications running on this server, under Applications, click Installed Applications.
Click to add new custom properties, update existing custom properties, or modify the timer
settings if the current settings are causing timeout problems.
- Click Review, select Synchronize changes with Nodes.
- Click Save to save any configuration changes that you made.
- If you made any configuration or custom property changes, start the application server, or stop
and restart the application server if it is already running.
Results
When you click , you can view the state of each server.
When you click , you can view any configuration changes you made.
What to do next
You can deploy applications or components to your application servers.
