PLUGGED_READONLY |
VARCHAR2(3) |
Indicates whether this is a proxy copy of a transported read-only foreign file (YES ) or not (NO ) |

NUMBER |
SCN at which the foreign datafile was transported into the database. The value is 0 if this file is not a foreign database file. |
PLUGIN_RESETLOGS_CHANGE# |
NUMBER |
