16) When using the WebSphere, Which three updates would force you to restart the test environment?
A) ----> These are the situation when you need to restart the server in test mode.
-----> 1) When you make any changes to the Class file(Bean , DAO etc)
-----> 2) Change any properties that were declared in properties file related to the whole application.
------> This is because initially properties file that were declared for the application will be loaded only when the server starts, and the server picks up thos key, values
------> 3) No need to restart if you make any change for jsp file. But you need to comeout of that particular page or refresh the page , so that it will recompile the modified jsp file and generate new contents

17) If the app server crashes in the middle of application deployment , what could be the reason and what steps we have to follow?
