ORA-600 [kcratr_scan_lastbwr] logical Bad blocks

Database Version:

11.2.0.3

Symptom:

When I started a test database today, I found that the database cannot be open. The error is as follows:

ERROR at line 1:

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

The alert Log is actually quite clear. In fact, you do not need to check the trace file. After a simple goole of surfing the Internet, there is a solution. Just pull it.
