Clean up state store of an Engine


Germain Engine contains a local database which keeps track of e.g. parsed log files. Sometime you just want to start from scratch and remove this local cache.


  1. Navigate to Germain Engine directory

  2. Make sure the Germain Engines are stopped

  3. Execute the following commands to clear & recreate the state store:

    cd database
    rm –rf hsqldb/*
    nohup ./
  4. Shut down state store DB

  5. Restart Germain Engines
