Stopping an application server

Stopping an application server ends a server process based on the process definition settings in the current application server configuration.

Before you begin

Make sure you understand the impact of stopping a particular server has on your ability to handle work requests, especially if you need to maintain a highly available environment.

About this task

There are times you need to stop an application server. For example, you might have to apply service to an application running on that server, or you might want to change one of the application server's configuration setting. Use one of the following options when you need to stop an application server.

Avoid trouble Avoid trouble: During the Application Server shutdown procecess, com.ibm.ejs.util.am._Alarm might launch new threads that cause unnecessary exceptions from varied components. For example, you might receive the following Connection Pool Manager exception:
J2CA0020E: Connection Pool Manager could not allocate a Managed Connection: 
java.lang.IllegalStateException: Internal     
Error: cannot find the PoolManager Reference. 
These exceptions might occur because an application server must shut down all of the components under that application servers control before the stop process can complete. You can ignore these exceptions. After the application server stops, all running threads from the application server automatically end. gotcha
