Invalidating a source file restores it to its state before it was verified, deleting the object model the parser created for the file.
               
               		Enterprise Analyzer automatically invalidates previously verified files when you reverify them. 
               	 
            
 
            	 
            When reverifying sources in the repository, all selected objects are invalidated prior to being verified. When the reverification
               is cancelled, all selected objects that were not verified, are invalidated. 
               	 
            
 
            	 
            You can save time reverifying very large applications by invalidating some or all of the source files in them before you reverify.
               You can invalidate: 
               	 
            
 
            	 
             
               		
               - The entire workspace in the 
                  		  Enterprise Analyzer Administration tool. Choose 
                  		  Administer > Invalidate Workspace. The Select workspace dialog opens, where you can select the workspace you want to invalidate. 
                  		
               
- Selected projects, folders, or files in the 
                  		  Enterprise Analyzer Repository pane. Select the items you want to invalidate and choose 
                  		  File > Invalidate Selected Objects. 
                  		
               
Invalidated files are displayed in 
               		bold type in the Repository pane. 
               	 
            
 
            	 
            Note: To improve performance when reverifying objects in the repository, all selected objects will be invalidated prior to being
               verified. When the reverification is cancelled, all selected objects that were not verified will be invalidated. 
               	 
            
 
            	 
            Note: To prevent the database transaction log from filling up during the invalidation of a large number of files, commits to the
               database are made regularly rather than waiting until the completion of the invalidation process. 
               	 
            
            	 
            Note: Invalidating an entire workspace is significantly faster than invalidating projects, folders, or files. 
               		
               
You must be a master user to invalidate source files. 
                  		
               
 
               		
               The invalidate workspace process opens several console windows displaying the progress of component tasks. Close these windows
                  manually when invalidation is complete.
