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

17:35:36 SYS@ test1>select userenv('LANGUAGE') FROM DUAL;

USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

RAC 环境：

17:46:03 SYS@ prod1>SELECT * FROM V$VERSION;

BANNER
--------------------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 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: 00:00:00.16

17:46:29 SYS@ prod1>select instance_name,status from gv$instance;

INSTANCE_NAME    STATUS
---------------- ------------
prod1            OPEN
prod2            OPEN

17:45:40 SYS@ prod1>select userenv('LANGUAGE') FROM DUAL;

USERENV('LANGUAGE')
----------------------------------------------------
AMERICAN_AMERICA.ZHS16GBK

2、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.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.8.21' (RSA) to the list of known hosts.
oracle@192.168.8.21's password:

您什麼時候應該使用複合索引與多個單列索引？Apr 11, 2025 am 12:06 AM

在數據庫優化中，應根據查詢需求選擇索引策略：1.當查詢涉及多個列且條件順序固定時，使用複合索引；2.當查詢涉及多個列但條件順序不固定時，使用多個單列索引。複合索引適用於優化多列查詢，單列索引則適合單列查詢。

如何識別和優化MySQL中的慢速查詢？（慢查詢日誌，performance_schema）Apr 10, 2025 am 09:36 AM

要優化MySQL慢查詢，需使用slowquerylog和performance_schema：1.啟用slowquerylog並設置閾值，記錄慢查詢；2.利用performance_schema分析查詢執行細節，找出性能瓶頸並優化。

MySQL和SQL：開發人員的基本技能Apr 10, 2025 am 09:30 AM

MySQL和SQL是開發者必備技能。 1.MySQL是開源的關係型數據庫管理系統，SQL是用於管理和操作數據庫的標準語言。 2.MySQL通過高效的數據存儲和檢索功能支持多種存儲引擎，SQL通過簡單語句完成複雜數據操作。 3.使用示例包括基本查詢和高級查詢，如按條件過濾和排序。 4.常見錯誤包括語法錯誤和性能問題，可通過檢查SQL語句和使用EXPLAIN命令優化。 5.性能優化技巧包括使用索引、避免全表掃描、優化JOIN操作和提升代碼可讀性。

描述MySQL異步主奴隸複製過程。Apr 10, 2025 am 09:30 AM

MySQL異步主從復制通過binlog實現數據同步，提升讀性能和高可用性。 1)主服務器記錄變更到binlog；2)從服務器通過I/O線程讀取binlog；3)從服務器的SQL線程應用binlog同步數據。

mysql：簡單的概念，用於輕鬆學習Apr 10, 2025 am 09:29 AM

MySQL是一個開源的關係型數據庫管理系統。 1）創建數據庫和表：使用CREATEDATABASE和CREATETABLE命令。 2）基本操作：INSERT、UPDATE、DELETE和SELECT。 3）高級操作：JOIN、子查詢和事務處理。 4）調試技巧：檢查語法、數據類型和權限。 5）優化建議：使用索引、避免SELECT*和使用事務。

MySQL：數據庫的用戶友好介紹Apr 10, 2025 am 09:27 AM

MySQL的安裝和基本操作包括：1.下載並安裝MySQL，設置根用戶密碼；2.使用SQL命令創建數據庫和表，如CREATEDATABASE和CREATETABLE；3.執行CRUD操作，使用INSERT,SELECT,UPDATE,DELETE命令；4.創建索引和存儲過程以優化性能和實現複雜邏輯。通過這些步驟，你可以從零開始構建和管理MySQL數據庫。

InnoDB緩衝池如何工作，為什麼對性能至關重要？Apr 09, 2025 am 12:12 AM

InnoDBBufferPool通過將數據和索引頁加載到內存中來提升MySQL數據庫的性能。 1)數據頁加載到BufferPool中，減少磁盤I/O。 2)臟頁被標記並定期刷新到磁盤。 3)LRU算法管理數據頁淘汰。 4)預讀機制提前加載可能需要的數據頁。

MySQL：初學者的數據管理易用性Apr 09, 2025 am 12:07 AM

MySQL適合初學者使用，因為它安裝簡單、功能強大且易於管理數據。 1.安裝和配置簡單，適用於多種操作系統。 2.支持基本操作如創建數據庫和表、插入、查詢、更新和刪除數據。 3.提供高級功能如JOIN操作和子查詢。 4.可以通過索引、查詢優化和分錶分區來提升性能。 5.支持備份、恢復和安全措施，確保數據的安全和一致性。
