Symptoms                                                                                                                                                                                   

The database is getting the following errors on Startup:

ORA-00600: internal error code, arguments: [kccpb_sanity_check_2], [3621501], [3621462], [0x000000000]

Changes                                                                                                                                                                                     

In this case, the customer moved the box from one data center to another.

Cause                                                                                                                                                                                         

ORA-600 [kccpb_sanity_check_2] indicates that the seq# of the last read block is higher than the seq# of the control file header block. This is indication of

the lost write of the header block during commit of the previous cf transaction.

Solution                                                                                                                                                                                      

1) restore a backup of a controlfile and recover OR

2) recreate the controlfile OR

3) restore the database from last good backup and recover

NOTE: If you do not have any special backup of control file to restore and you are using Multiple Control File copies in your pfile/init.ora/spfile you can attempt to mount the database using each control file one by one. If you are able to mount the database with any of these control file copies you can then issue 'alter database backup controlfile to trace' to recreate controlfile.
