Starting an application server

Starting an application server starts a new server process based on the process definition settings of the current server configuration.

Before you begin

Before you start an application servers verify that all of the resources. that the applications running on this server require, are available. You must also start all prerequisite subsystems.

Avoid trouble Avoid trouble:
  • To ensure compatibility with other WebSphere® products, the default setting for the Start components as needed option is cleared. Before selecting this option, verify that any other WebSphere products, that you are running with this product, support this function.
  • When you start an application server from the console, the application server inherits the node agent's environment, including the ulimit settings. Setting the ulimit to the needed valude might need to be done at the node agent level such that the application server inherits the right values from the node agent.
  • When you start an application server from a command line, you must specify the ulimit settings in the OS shell before you issue the startServer command because in this scenario, the application server inherits the ulimit settings of the OS shell.
gotcha

About this task

This procedure for starting a server also normally applies to restarting a server. The one exception might be if a server fails and you want the recovery functions to complete their processing prior to new work being started on that server. In this situation you must restart the server in recovery mode.

If you create a new application server definition using a base WebSphere Application Server, you cannot start, stop, or manage the new server using the administrative console that is associated with the original base server. You must use commands to perform these tasks for the new server.

There are several options available for starting an application server.

Procedure

Results

The specified server starts. To verify that the server is in start state, in the administrative console, click Servers > Application Servers.

What to do next

After the server starts, deploy the applications that you want to run on this server.
If you need to start an application server with standard Java debugging enabled:
  1. In the administrative console, click Servers> Application Servers, and then click the application server with the processes that you want to trace and debug.
  2. Under Server Infrastructure, click Java and Process Management > Process Definition.
  3. Select Java Virtual Machine.
  4. On the Java virtual machine page, select the Debug Mode option to enable the standard Java debugger. Set Debug Mode arguments, if they are needed, and then, click OK.
  5. Save the changes to a configuration file
  6. Stop the application server.
  7. Start the application server again as previously described.
