3、One data block corresponds to a specific number of bytes of physical database space on disk.
一個(gè)數(shù)據(jù)塊對應(yīng)于一個(gè)特定數(shù)量字節(jié)的磁盤上的物理數(shù)據(jù)庫空間。

4、This portion of the data block contains information about the table having rows in this block.
數(shù)據(jù)塊的這部分包涵了關(guān)于數(shù)據(jù)塊中擁有行的表的信息。

6、When a RAC instance requires a data block that is currently being updated on the local instance.
當(dāng)某個(gè)RAC實(shí)例要求一個(gè)數(shù)據(jù)塊，這個(gè)數(shù)據(jù)塊當(dāng)前正在被本地實(shí)例修改，那么這個(gè)需求。

7、In an Oracle rac environment, every Oracle data block is assigned one "Master" Oracle rac node.
