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

July 5, 2012

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


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.
