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.
