ORA-00218 Block Size String of Control File 'string' does not match DB_BLOCK_SIZE

Error Code
ORA-00218

Description
Block size string of control file 'string' does not match DB_BLOCK_SIZE (string)

This might be due to an incorrect setting of DB_BLOCK_SIZE, or else might indicate that the control file has either been corrupted or belongs to a different database.
