Information for Database Error Code ORA-00218: block size string of control file [string] does not match DB_BLOCK_SIZE (string)
Oracle® Database Error ORA-00218142/4

ORA-00218: block size string of control file [string] does not match DB_BLOCK_SIZE (string)

Cause: The block size as stored in the control file header is different from the value of the initialization parameter DB_BLOCK_SIZE. 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.

Action: Restore a good copy of the control file. If the control file is known to be clean set the DB_BLOCK_SIZE to match control file headers block size value.

Error Type: ORA
