When you issue this command, the control file will be backed up to your current session's trace file. If that trace file already exists, then the information is appended to that existing trace file. If the trace file does not exist, a new one is created. If you get out of SQL*Plus and start a new session, it will receive a new session identifier and the control file backup to trace will be placed in a new trace file.
