第1章 Oracle 12C概述

1.1.3 数据类型
整数数据类型 浮点数数据类型 精确小数类型 二进制数据类型 日期/时间数据类型 字符串数据类型
1.1.4 主键
主键(PRIMARY KEY)又称主码,用于唯一地标识表中的每一条 记录。可以定义表中的一列或多列为主键,主键列上不能有两行 相同的值,也不能为空值。
1.2 数据库技术构成
数据库(DataBase,DB)是一个长期存储在计算机内的、有组织 的、有共享的、统一管理的数据集合。它是一个按数据结构来存 储和管理数据的计算机软件系统。即数据库包含两层含义:保管 数据的“仓库”,以及数据管理的方法和技术。
数据库的特点包括:实现数据共享,减少数据冗余;采用特定的 数据类型;具有较高的数据独立性;具有统一的数据控制功能。
1979年,RSI首次向客户发布了产品,即第2版。 1983年,发布的第3个版本中加入了SQL语言,而且性能也有所提升,其
他功能也得到增强。同年,RSI更名为Oracle Corporation,也就是今天 的Oracle公司。 …. …. …. 2013年6月26日,Oracle Database 12c版本正式发布,12c里面的c是 cloud,也就是代表云计算的意思。
1.4 Oracle工具
1.4.1 SQL Plus 1.4.2 Oracle SQL Developer
1.4.1 SQL Plus
客户端工具。在SQL Plus中,可以运行SQL Plus命令与sql语句。 SQL Plus是目前最常用的工具,具有很强的功能,主要功能包含如
下: ⑴ 数据库的维护,如启动,关闭等,这一般在服务器上操作。 ⑵ 执行SQL语句。 ⑶ 执行SQL脚本。 ⑷ 数据的导出为报表。 ⑸ 应用程序开发、测试SQL。 ⑹ 生成新的SQL脚本。 ⑺ 供应用程序调用,如安装程序中进行脚本的安装。 ⑻ 用户管理及权限维护等。

Oracle Database 12c十二大新特性

作为甲骨文全球大会OpenWorld 2012中的重要产品发布,新版Oracle Database 12c汇集了参会者最多的目光,Larry Ellison也在开幕演讲中重点介绍了12c 的一些新特性。
对于Oracle DBA来说,虽然数据库12c正式发布的日期还要等到明年年初,但依旧希望能够提前了解它的一些新功能、新特性。
在OpenWorld 2012的技术讲座环节,Oracle技术大师Tom Kyte集中介绍了Oracle Database 12c的十二大新特性,而Oracle ACE总监杨廷琨也对此进行了总结,希望让国内DBA一睹为快。
1.PL/SQL性能增强:类似在匿名块中定义过程,现在可以通过WITH语句在SQL中定义一个函数,采用这种方式可以提高SQL调用的性能。
2.改善Defaults:包括序列作为默认值;自增列;当明确插入NULL时指定默认值;METADATA-ONLY default值指的是增加一个新列时指定的默认值,和11g 中的区别在于,11g的default值要求NOT NULL列。
3.放宽多种数据类型长度限制:增加了VARCHAR2、NVARCHAR2和RAW类型的长度到32K,要求兼容性设置为12.0.0.0以上,且设置了初始化参数MAX_SQL_STRING_SIZE为EXTENDED,这个功能不支持CLUSTER表和索引组织表;最后这个功能并不是真正改变了VARCHAR2的限制,而是通过OUT OF LINE的CLOB 实现。
4.TOP N的语句实现:在SELECT语句中使用“FETCH next N rows”或者“OFFSET”,可以指定前N条或前百分之多少的记录。
5.行模式匹配:类似分析函数的功能,可以在行间进行匹配判断并进行计算。
在SQL中新的模式匹配语句是“match_recognize”。
6.分区改进:Oracle Database 12c中对分区功能做了较多的调整,Oracle ACE总监杨廷琨花了较大的篇幅对分区提升进行了解读,其中共分成6个部分:INTERVAL-REFERENCE分区:把11g的interval分区和reference分区结合,这样主表自动增加一个分区后,所有的子表、孙子表、重孙子表、重重重...孙子表都可以自动随着外接列新数据增加,自动创建新的分区。
oracle12c 内存数据库(IN-MEMORY)使用手册

启动Oracle数据库12c的第1版(12.1.0.2),在内存中的列存储(IM列存储)是存储表和分区的副本进行快速扫描优化的特殊柱状格式可选,静态SGA池。
在IM列存储不更换缓存,但作为一个补充,使这两个存储区可存储不同格式相同的数据。
默认情况下,仅使用DDL 对象指定的inmemory的候选人将填充在IM列存储。
柱状格式只存在于内存中。
图14-8显示了存储在IM列存储SH模式三个表:客户,产品和销售。
在IM列存储通过柱,而不是行存储数据。
该数据库保持柱状数据缓冲区高速缓存事务一致性。
本节包含了以下主题:在IM列存储的好处双存储格式:纵栏和行在内存中的列存储的人口在内存列压缩扫描优化的IM列存储在IM列存储的好处在IM列存储使得数据库进行扫描,联接和聚合时相比,它使用的磁盘格式完全快得多。
特别是,对于IM列存储是很有用的:扫描行数和应用使用运营商,如=过滤器,<,>,和IN查询列的子集在表中,例如,选择5 100的列加快加入通过将小维表谓词到过滤器上的一个大的事实表业务应用,即席分析查询和数据仓库工作负载受益最大。
执行使用索引查找短事务纯OLTP 数据库中受益较少.在IM列存储还具有以下优点:所有现有的数据库功能都支持,包括高可用性功能(参见“高可用性概述”)。
没有应用程序的改变是必需的。
优化器会自动柱状格式的优势。
配置简单。
该INMEMORY_SIZE初始化参数指定的内存预留供IM列存储的使用量。
DDL语句指定表空间,表,分区或列被读入IM列存储。
压缩优化的查询性能。
这些压缩技术通过使会话读取更多的数据到内存中增加有效的内存带宽。
更少的索引,物化视图和OLAP多维数据集是必需的。
在预先建立的对象的数量的减少导致了降低的存储空间和显著较少的处理开销双存储格式:纵栏和行当读取数据时,Oracle数据库可以在同一个查询中读取无论是IM列存储或数据库缓冲区高速缓存,或两者兼而有之。
数据库透明发送OLTP查询(如主键查找)的缓冲区高速缓存,以及分析和报告查询到IM列存储。
Oracle 数据库12c新特性总结

Oracle 数据库12c新特性总结导读:本系列文章是Oracle ACE总监Syed Jaffer Hussain对Oracle数据库12c的一些新特性总结,包括数据库管理、RMAN、高可用性以及性能调优等内容。
关键词:Oracle数据库12c RMAN PGA限制不可见字段【TechTarget中国原创】编者按:甲骨文公司近日正式发布了新版旗舰级数据库Oracle Database 12c,在TechTarget数据库网站之前的一些报道中,我们曾对12c的一些新特性进行了介绍(参考:尝鲜Oracle Database 12c的十二大新特性)而随着产品正式GA,相关技术文档也披露了更多关于12c数据库的细节。
本系列文章是Oracle ACE总监Syed Jaffer Hussain对Oracle 数据库12c的一些新特性总结,包括数据库管理、RMAN、高可用性以及性能调优等内容。
Oracle 数据库12c新特性总结(一)在第一部分中,我们将介绍:1. 在线迁移活跃的数据文件2. 表分区或子分区的在线迁移3. 不可见字段4. 相同字段上的多重索引5. DDL日志6. 临时undo7. 新的备份用户特权8. 如何在RMAN中执行SQL语句9. RMAN中的表级别恢复10. PGA的大小限制问题1. 在线重命名和重新定位活跃数据文件不同于以往的版本,在Oracle数据库12c R1版本中对数据文件的迁移或重命名不再需要太多繁琐的步骤,即把表空间置为只读模式,接下来是对数据文件进行离线操作。
在12c R1中,可以使用ALTER DATABASE MOVE DATAFILE这样的SQL语句对数据文件进行在线重命名和移动。
而当此数据文件正在传输时,终端用户可以执行查询,DML以及DDL方面的任务。
另外,数据文件可以在存储设备间迁移,如从非ASM迁移至ASM,反之亦然。
重命名数据文件:SQL> ALTER DATABASE MOVE DATAFILE '/u00/data/users01.dbf' TO '/u00/data/u sers_01.dbf';从非ASM迁移数据文件至ASM:SQL> ALTER DATABASE MOVE DATAFILE '/u00/data/users_01.dbf' TO '+DG_DATA ';将数据文件从一个ASM磁盘群组迁移至另一个ASM磁盘群组:SQL> ALTER DATABASE MOVE DATAFILE '+DG_DATA/DBNAME/DATAFILE/users_0 1.dbf ' TO '+DG_DATA_02';在数据文件已存在于新路径的情况下,以相同的命名将其覆盖:SQL> ALTER DATABASE MOVE DATAFILE '/u00/data/users_01.dbf' TO '/u00/data_ new/users_01.dbf' REUSE;复制文件到一个新路径,同时在原路径下保留其拷贝:SQL> ALTER DATABASE MOVE DATAFILE '/u00/data/users_01.dbf' TO '/u00/data_ new/users_01.dbf' KEEP;当通过查询v$session_longops动态视图来移动文件时,你可以监控这一过程。
