Can the Tomcat work directory be cleared?

Yes, the Tomcat work directory can be cleared.

Cause

The work directory is used to store temporary files such as compiled JSP files and session information. These files are generally not needed after a server restart or application redeployment. Therefore, emptying the work directory can free up disk space and improve performance.

Clear the work directory

There are two methods to clear the work directory:

• Manual clearing:

  1. Stop the Tomcat server.
  2. Navigate to the work directory (usually located in the webapps directory under the Tomcat installation directory).
  3. Delete all files and subdirectories in the directory.

• Auto clear:

  1. Add the following code in the Tomcat configuration file:

     <Context path="/myContext" ...>
     <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log." suffix=".txt" rotatable="false" />
     <Manager pathname="" />
     </Context>

  2. Set the pathname attribute to a directory that does not exist. This will cause Tomcat to automatically empty the work directory on startup.

Note

• Clearing the work directory will not affect deployed applications or session information.
• Before emptying the work directory, make sure you have backed up any required files.
• If the application uses temporary sessions, the sessions will be lost after clearing the work directory.
