You cannot put the datafiles in Offline when your DB is in No Archive Log mode.

So below are the steps to recover the database considering current situation :

  1. Shutdown immediate;

  2. startup nomount;

  3. Recreate the control file using backup trace. :

    alter database backup controlfile to trace as '$ORACLE_HOME/dbs/control_new.sql';

Now make changes in the created control_new.sql:

CREATE CONTROLFILE REUSE DATABASE "db_name" RESETLOGS ARCHIVELOG  
   MAXLOGFILES 16  
   MAXLOGMEMBERS 3  
   MAXDATAFILES 100  
   MAXINSTANCES 8  
   MAXLOGHISTORY 2921  
 LOGFILE  
  GROUP 1 '/u01/app/oracle/oradata/db_name/redo1.log' SIZE 400M,  
  GROUP 2 '/u01/app/oracle/oradata/db_name/redo2.log' SIZE 400M,  
  GROUP 3 '/u01/app/oracle/oradata/db_name/redo3.log' SIZE 400M,  
  GROUP 4 '/u01/app/oracle/oradata/db_name/redo4.log' SIZE 400M,  
  GROUP 5 '/u01/app/oracle/oradata/db_name/redo5.log' SIZE 400M,  
  GROUP 6 '/u01/app/oracle/oradata/db_name/redo6.log' SIZE 400M  
 -- STANDBY LOGFILE  
 DATAFILE  
  '/u01/app/oracle/oradata/db_name/system01.dbf',  
 ...  
  '/u01/app/oracle/oradata/db_name/FCJ_DATA_TS_13.dbf'  
 CHARACTER SET AL32UTF8;
  1. RUn the file in SQL prompt :

    @$ORACLE_HOME/dbs/control_new.sql

5.Mount the database :

alter database mount;
  1. Recover database using control file:

    Recover database using backup control file until cancel;

  2. Now open the database : alter database open;

  • after following the same I got a data dictionary mismatch error: ORA-01173: data dictionary indicates missing data file from system tablespace – amyassin Oct 28 '18 at 8:48
