The format of the cache header was changed for Oracle8. Under Oracle8 and 9, the value is always 2. Previously, it was 1.

5
The tablespace relative database block address (RDBA). This is constructed from the tablespace relative file number (10 bits),
and the block number of the data block within that file (22 bits).
 RDBA:0x02C00003
6
The SCN at which the block was last changed. The low-order 4 bytes are called the SCN base, and the high-order 2 bytes are called the SCN wrap.
scn: 0x0000.00049341
7
A sequence number incremented for each change to a block at the same SCN. If the sequence
number wraps, a new SCN must be allocated.  The value 0xff is reserved. When present it
indicates that the block has been marked as corrupt by Oracle.
seq:0x01
8
Flag.
1 - virgin block
2 - last change to the block was for a cleanout operation
4 - checksum value is set
8 - temporary data
flg:0x04
9
An optional checksum of the block contents. When a block is written, the checksum is either cleared or set depending on the setting of the db_block_checksum
parameter. When a block is read, the checksum is verified if present and if the parameter is set to TRUE. Checksums are always calculated and checked for blocks
in the SYSTEM tablespace. The checksum is the XOR of all the other 2-byte pairs in the block. Thus when a block with a checksum is checked, the XOR of all the 2-
byte words in the block should be 0.

Tail is comprised of the low-order two bytes of the SCN base followed by the block type and the sequence number. The consistency of the header and tail is
checked whenever a block is read. This detects most block corruptions, in particular split blocks from hot backups.
