ORA-00600: internal error code, arguments: [kcratr1_lastbwr]

Some time we encounter this error while starting the database. Below is the solution for recovering through this error.

Error:

SQL> startup
ORACLE instance started.

Fixed Size 1264916 bytes
Variable Size 264241900 bytes
Database Buffers 801112064 bytes

Database mounted.
ORA-00600: internal error code, arguments: [kcratr1_lastbwr], [], [], [], [],
[], [], []

Encountered in : 10.2.0.2.0 Database

Cause:

Oracle is unable to perform instance recover but it works when is invoked manually.

Solution:

SQL> startup mount
ORACLE instance started.
