The location you choose for Ingres system (executable and script) files will also contain the error log and configuration files. Choose a location that has adequate disk space (at least 2 GB free).

If you lose this location, Ingres will fail. Replace the failed component, restore the file system from backup. Ingres will recover on startup.

If you fill this file system, Ingres will fail. Free some space or allocate additional space, and restart Ingres if necessary.
