Oracle单实例数据库迁移到Oracle RAC环境之--数据导出导入
系统环境：
操作系统：RedHat EL55
Oracle ： Oracle 11.2.0.1.0
集群软件：Oracle GI 11.2.0.1.0
本案例采用的是通过数据的导入导出（EXPDP/IMPDP)的迁移方式
从单实例的库迁移数据到RAC环境，可以有多种方式，通过数据的导出和导入也可以，但前提是数据库采用相同的字符集。
1、数据库环境
单实例：
17:35:59 SYS@ test1>SELECT * FROM V$VERSION;
BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production PL/SQL Release 11.2.0.1.0 - Production CORE 11.2.0.1.0 Production TNS for Linux: Version 11.2.0.1.0 - Production NLSRTL Version 11.2.0.1.0 - Production Elapsed: 00:00:00.02

----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK2、建立测试环境
单实例：
17:38:26 SYS@ test1>create tablespace test01
17:41:40 2 datafile '/dsk1/oradata/test1/test01.dbf' size 100m;
Tablespace created.
17:43:49 SYS@ test1>create user test1 identified by test1
17:44:00 2 default tablespace test01
17:44:00 3 temporary tablespace tmpgp1
17:44:00 4 quota unlimited on test01
17:44:00 5 account unlock;
17:44:00 SYS@ test1>grant connect ,resource to test1;
Grant succeeded.
17:50:34 SYS@ test1>conn test1/test1
Connected.
17:50:41 TEST1@ test1>create table testtb1 tablespace test01 as select * from scott.emp;
Table created.
Elapsed: 00:00:00.25
17:50:52 TEST1@ test1>create index test_empno_ind on testtb1(empno) tablespace indx;
Index created.
Elapsed: 00:00:00.05
如果做表空间传输，需要对表空间做自包含检测：
17:51:15 SYS@ test1>EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK('test01', TRUE);
PL/SQL procedure successfully completed.
Elapsed: 00:01:04.07
17:52:25 SYS@ test1>SELECT * FROM TRANSPORT_SET_VIOLATIONS;
no rows selected
Elapsed: 00:00:00.05
创建导出传输目录：
17:52:43 SYS@ test1>create directory exp_dir as '/home/oracle/exp';
Directory created.
Elapsed: 00:00:00.07
17:53:24 SYS@ test1>grant read,write on directory exp_dir to test1;
Grant succeeded.
Elapsed: 00:00:00.06
17:53:39 SYS@ test1>!mkdir ~/exp
导出schema：
[oracle@rh6 exp]$ expdp test1/test1 directory=exp_dir dumpfile=test.dmp logfile=test.log schemas=test1

3、在RAC环境下导入数据：
从单实例传输dump文件到RAC环境下：
[oracle@rh6 exp]$ scp *.dmp 192.168.8.21:/u01/exp
The authenticity of host '192.168.8.21 (192.168.8.21)' can't be established. RSA key fingerprint is 39:04:88:3b:54:34:3c:34:d2:df:74:37:fe:5f:92:2d.

在RAC下建立表空间和Schema：

建立数据导入目录：

导入数据：

[oracle@node1 ~]$ cd /u01/exp
[oracle@node1 exp]$ ls

@至此，数据迁移完成！
oracle怎么查询所有索引May 13, 2022 pm 05:23 PM方法：1、利用“select*from user_indexes where table_name=表名”语句查询表中索引；2、利用“select*from all_indexes where table_name=表名”语句查询所有索引。
什么是oracle asmApr 18, 2022 pm 04:16 PMoracle asm指的是“自动存储管理”，是一种卷管理器，可自动管理磁盘组并提供有效的数据冗余功能；它是做为单独的Oracle实例实施和部署。asm的优势：1、配置简单、可最大化推动数据库合并的存储资源利用；2、支持BIGFILE文件等。
oracle全角怎么转半角May 13, 2022 pm 03:21 PM在oracle中，可以利用“TO_SINGLE_BYTE(String)”将全角转换为半角；“TO_SINGLE_BYTE”函数可以将参数中所有多字节字符都替换为等价的单字节字符，只有当数据库字符集同时包含多字节和单字节字符的时候有效。
Oracle怎么查询端口号May 13, 2022 am 10:10 AM在Oracle中，可利用lsnrctl命令查询端口号，该命令是Oracle的监听命令；在启动、关闭或重启oracle监听器之前可使用该命令检查oracle监听器的状态，语法为“lsnrctl status”，结果PORT后的内容就是端口号。
oracle怎么删除sequenceMay 13, 2022 pm 03:35 PM在oracle中，可以利用“drop sequence sequence名”来删除sequence；sequence是自动增加数字序列的意思，也就是序列号，序列号自动增加不能重置，因此需要利用drop sequence语句来删除序列。
oracle怎么查询数据类型May 13, 2022 pm 04:19 PM在oracle中，可以利用“select ... From all_tab_columns where table_name=upper('表名') AND owner=upper('数据库登录用户名');”语句查询数据库表的数据类型。
oracle查询怎么不区分大小写May 10, 2022 pm 05:45 PM方法：1、利用“LOWER(字段值)”将字段转为小写，或者利用“UPPER(字段值)”将字段转为大写；2、利用“REGEXP_LIKE(字符串,正则表达式,'i')”，当参数设置为“i”时，说明进行匹配不区分大小写。
Oracle怎么修改sessionMay 13, 2022 pm 05:06 PM方法：1、利用“alter system set sessions=修改后的数值 scope=spfile”语句修改session参数；2、修改参数之后利用“shutdown immediate – startup”语句重启服务器即可生效。
