Du skal montere databasen (ikke åbne den) og genskabe kontrolfilen og omdøbe datafilerne i processen (se OPRET KONTROLFIL kommando):
STARTUP MOUNT;
CREATE CONTROLFILE REUSE SET DATABASE "ORCL" RESETLOGS
MAXLOGFILES NN
MAXLOGMEMBERS N
MAXDATAFILES 254
MAXINSTANCES 1
MAXLOGHISTORY 1815
LOGFILE
GROUP 1 '/home2/oracle/oradata/ccisv2/REDO01.LOG' SIZE 56M,
GROUP 2 '/home2/oracle/oradata/ccisv2/REDO02.LOG' SIZE 56M,
GROUP 3 '/home2/oracle/oradata/ccisv2/REDO03.LOG' SIZE 56M
DATAFILE
'/home2/oracle/oradata/ccisv2/SYSTEM.DBF',
'/home2/oracle/oradata/ccisv2/USERS.DBF',
'/home2/oracle/oradata/ccisv2/sysaux.DBF',
'/home2/oracle/oradata/ccisv2/TOOLS.DBF',
etc...
CHARACTER SET WE8ISO8859P1;
ALTER DATABASE OPEN RESETLOGS;
QUIT;
Alle dine databasefiler skal genidentificeres i kontrolfilen med deres nye placering.
