Clearing the SUM cache
SUM stores node information between sessions, including user credentials for nodes, in a database file. The 
		  clean-cache removes the database information. The command does not delete the log directories or files.
		
- Shut down the SUM engine.
 - From a command-line window, navigate to the directory that contains SUM.
 -  
		  Type 
			 
clean-cache.bat(Windows) orclean-cache.sh(Linux).NOTE:If you are using a GUI, you can navigate to the directory that holds SUM and run
clean-cacheto clear the cache. Running the clean-cache command erases all nodes, baselines, and other information entered in SUM.
