You can use either the administrative console or command-line tools to manage your application servers.
If
you plan to change the system clock, stop all the application servers,
the node agent servers, the deployment manager server, the administrative
agent server, and the job manager server first. After 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 errors, such as
security tokens no longer being valid.
If
you plan to change the system clock, stop all the application servers,
the node agent servers, the deployment manager server, the administrative
agent server, the job manager server, and the location service daemon
first. After you stop the servers and location service daemon, change
the system clock, and then restart the servers and location service
daemon. 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 errors, such as
security tokens no longer being valid.
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. Starting with Version
6 Release 1 of the operating system, the delay could be several seconds.
If your application server is on an earlier version of the operating
system, the delay could be as much as an hour. 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.
You can perform the following steps to view and manage an application server from the administrative console.
When you click
, you can view the state of each server.When you click
server_name, you can view any configuration changes you made.You can deploy applications or components to your application servers.
