HOW to increase DB_FILES?

From: <thomasl_at_expansion.com>

Lando/others,

  Why can't you just up the db_files = <higher or lower value> stop and restart the datbase?

Should the database read the parameter and readjust the configuration automatically?

please email thomasl_at_earthlink.net

Thanks

Thomas
