+- CDB :容器数据库，名称为 CDB$ROOT。其作用就是系统数据库，sys等账号都保存在里面。同时它可以管理PDB数据库
+
+- PDB ：可插拔的数据库。用户可以在PDB自建数据库

+  - PDB中自带有PDB$SEED，属于PDB的模板数据库，自己创建数据库的时候以此库为模板

+## 表空间
+
+### 概述
+
+1. 表空间
+   1. 表空间是一个逻辑的概念，真正存放数据的是数据文件(data files)
+   2. 1 个数据库 = N 个表空间(N >= 1)
+      1 个表空间 = N 个数据文件(dbf)（N >= 1）
+      -- 1个数据文件(dbf) 只能属于 1 个表空间
+2. 建立表空间的作用
+   1. 控制数据库占用 '磁盘空间' 的大小
+   2. 不同类型的数据存储到不同的位置，有利于提高 'I/O' 性能，同时有利于备份和恢复等操作
+
+### 相关视图

+
+## 特性
+
+### Row Movement
+
+ROW MOVEMENT特性最初是在8i时引入的，其目的是提高分区表的灵活性——允许更新Partition Key。这一特性默认是关闭，只是在使用到一些特殊功能时会要求打开。除了之前提到的更新Partition Key，还有2个要求打开的ROW MOVEMENT的功能就是flushback table和Shrink Segment。
+
+先看Flashback Table。这一功能能帮助我们及时回滚一些误操作，防止数据意外丢失。在使用该功能之前，必须先打开ROW MOVEMENT，否则就会抛ORA-08189错误。我们看以下例子，可以说明在使用Flashback Table功能时，ROW MOVEMENT产生了什么作用：
+
+当开启ROW MOVEMENT后，表被顺利的flashback了，数据被找回。此时，再比较flashback前后记录的ROWID，大多数记录的物理位置都变化。这个过程的内部操作， 可以通过对Flashback Table做SQL Trace来进一步观察。
+
+通过Trace，我们不难发现，Flashback Table实际是通过Flashback Query将表中数据进行了一次删除、插入操作，因此ROWID会发生变化。
+
+
+
+在更新记录中的Partition Key时，可能会导致该记录超出当前所在分区的范围，需要将其转移到其他对应分区上，因此要求开启ROW MOVEMENT。
+
+这一操作产生影响的特殊之处在于这是个DML操作，是和online transaction密切相关。对于这样一个UPDATE，实际上分为3步：先从原有分区将数据删除；将原数据转移到新分区上；更新数据。
+
+其影响就在于以下几个方面：
+
+- 一个UPDATE被分解为DELET、INSERT、UPDATE三个操作，增加了性能负担。其中，DELETE的查询条件与原UPDATE的查询条件相同，新的UPDATE的查询条件是基于INSERT生成的新的ROWID；
+
+- 相应的Redo Log、Undo Log会增加；
+
+- 如果Update语句还涉及到了Local Index的字段的话，新、旧2个分区上的Local Index都要被更新。

+
+### 自动分区
+
+在Oracle Database 12.2 之前，如果使用列表分区，当插入的数据超过了分区列表值设定，则会抛出异常；而如果存在大量的列表值需要定义，则可能需要一一设置。
+
+在12.2引入的新特性中 - Auto-List Partitioning 可以针对新的列表值，进行自动的分区创建，从而减少了维护的复杂性。
+
+```sql
+drop table enmotech purge;
+
+CREATE TABLE enmotech (
+  PartID	integer		not null,
+  CretTm	date		not null,
+  PartCD	varchar2(2)	not null
+) partition by list (partcd) automatic (
+  partition pBJ values ('BJ'),
+  partition pCD values ('CD'),
+  partition pGZ values ('GZ'),
+  partition pSH values ('SH')
+);
+
+```
+
+如果这个自动分片的分区名不符合你的命名规则，可以通过DDL语句去修改变更
+
+```sql
+alter table enmotech rename partition SYS_P290 to pKM;
+```
+
+对于已有的分区定义，可以通过关键字 automatic 和 manual 来进行分区定义的调整
+
+```sql
+alter table PEOPLE set partitioning automatic;
+
+alter table PEOPLE set partitioning manual;
+```
+
