# 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.

Procedure

1. Shut down the SUM engine.
2. From a command-line window, navigate to the directory that contains SUM.
3. Type `clean-cache.bat` (Windows) or `clean-cache.sh` (Linux).
   NOTE:

   If you are using a GUI, you can navigate to the directory that holds SUM and run `clean-cache` to clear the cache. Running the clean-cache command erases all nodes, baselines, and other information entered in SUM.
