大家可以看到，这跟普通的data block的dump内容是有所差别的，因为这里涉及到cluster table。

下面来模拟下手工提交cluster table的事务。

这里我们可以看到对于这个未提交的事务XID为：3.17.1212  前面我们已经知道

测试表中的数据分布在3个block中，这里我模拟的情况是删除第3条数据，且不提交，通过bbed来实现手工

提交这个未提交事务，注意：第3条数据是在第3个block中，即174 block。

+++++首先修改表的itl等信息

我们可以看到，无论怎么修改，这个block通过bbed进行检测都报错，这里不是因为修改的不对,而是因为

还需要修改cluster 上的Index信息。通过treedump 我们可以确认index block为file 6 block 187.

ORACLE中创建表空间，创建表，修改表，授权

创建表空间 /*分为四步 */ /*第1步:创建临时表空间  */ create temporary tablespace user_temp tempfile 'D:\oracle\oradata\Oracle9i\user_temp.dbf' size 50m autoextend on next 50m maxsize 20480m   //如果最大值没有上限,则使用unlimited extent management local;  //extent 表示区间  设置区间管理方式是本地

4.事务提交过程，事务基本概念，Oracle中的事务生命周期，保存点savepoint,数据库的隔离级别

 事务提交过程 事务 基本概念 概念:一个或者多个DML语言组成 特点:要么都成功,要么都失败 事务的隔离性:多个客户端同时操作数据库的时候,要隔离它们的操作, 否则出现:脏读  不可重复读  幻读 Oracle默认情况下,事务是打开的 commit案例: SQL> create table t1(tid int,tname varchar2(20)); 表已创建. SQL> select * from tab; TNAME                          TABTYPE
