ORA-00600: internal error code, arguments: [kcratr_scan_lastbwr], [], [], []

The Problem:

Oracle Database remains in mounted state. It can't be opened. If it is focibly opened it throws error (ora-00600) as shown below:

SQL> alter database open;
alter database open
*
ERROR at line 1:

[], [], [], [], [], [], [], []

SOLUTION:

Use the command- 'recover database' as shown below:

SQL> shutdown immediate
ORA-01109: database not open


Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
