Related Error Messages:

Cause: DB_BLOCK_SIZE initialization parameter is wrong for the database being mounted. It does not match the value used to create the database.

Action: Fix the value of the DB_BLOCK_SIZE parameter or mount a database that matches the value.

ORA-00209: control file blocksize mismatch, check alert log for more info

Cause: The block size in the control file header does not match the size specified in the DB_BLOCK_SIZE parameter.

Action: Look at the alert log for more information.

ORA-00218: block size %s of controlfile '%s' does not match DB_BLOCK_SIZE (%s)

Cause: The block size as stored in the controlfile 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 controlfile has either been corrupted or belongs to a different database.

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

ORA-00374: parameter db_block_size = %s invalid ; must be a multiple of %s in the range [%s..%s]

Cause: invalid value for db_block_size parameter

Action: adjust parameter and restart

ORA-00375: unable to get default db_block_size

Cause: the system was unable to determine the default db_block_size

Action: see accompanying system specific error. As a workaround, specify the blocksize in the INIT.ORA file.

ORA-06580: Hash Join ran out of memory while keeping large rows in memory

Cause: Hash Join reserves 3 slots (each slot size = DB_BLOCK_SIZE * HASH_JOIN_MULTIBLOCK_IO_COUNT) for a row. If a row is larger than that, this error will be raised.

Action: Increase HASH_JOIN_MULTIBLOCK_IO_COUNT so that each joined row fits in a slot. HASH_AREA_SIZE may also need to be increaed.

ORA-07303: ksmcsg: illegal database buffer size.

Cause: The database buffer size must be a multiple of the database block size, and less than the maximum block size.

Action: Verify that the db_block_size parameter is correct in INIT.ORA.

ORA-07305: ksmcsg: illegal database buffer size.

Cause: The database buffer size must be a multiple of the extended cache mapping size for indirect data buffers to be used.

Action: Verify that the db_block_size parameter is correct in INIT.ORA, or disable the use_indirect_data_buffers parameter.

ORA-07620: smscre: illegal database block size

Cause: An illegal database block size was specified in the parameter file. It must be positive, a multiple of 512, and less than the maximum physical i/o data size.

Action: Change db_block_size in the parameter file to conform to these limits.
