Starting the WebSphere Application Server
Note: By default, WebSphere Application
                Server 7.0 creates and configures a default server named 
        server1
                during installation. If you named your server something other than the default
                value, then substitute that name for server1 in the following
                steps.To start the WebSphere Application Server:
Start a command prompt.
Navigate to the
<websphere_install_dir>\AppServer\profiles\profile_name\binWebSphere/AppServer/profiles/profile_name/bindirectory. For example:cd Z:\IBM\WebSphere\AppServer\profiles\AppSrv01\bincd /u01/IBM/WebSphere/AppServer/profiles/AppSrv01/binIssue the command
startServerfollowed by the Application Server name. For example:Z:\IBM\WebSphere\AppServer\profiles\AppSrv01\bin > startServer server1./startServer.sh server1
This command is case sensitive.
Tip: The
                Application Server can also be started through the Windows Services Applet. Each
                profile that you configured will have a corresponding service that is automatically
                created when you created the profile.
        Note: Starting with Tools Release 8.97,
                you can use the Server Manager to start the WebSphere process.
