oracle 11g数据库迁移(不同目录不同主机
1、创建监听、服务
2、备份源库的数据文件、初始化参数文件和控制文件

3、复制归档日志到目标数据库
4、创建密码文件和OracleService testdb
5、恢复初始化参数文件
使用生產環境的spfile，或者從備份集中恢復出spfile，并使用這個spfile，打開資料庫到nomount狀態，
或者創建一個初始化參數文件INITtestdb.ora，裏面就一句話:db_name=testdb保存，restore spfile to pfile ‘d:\app\h2603027\product\11.2.0\db_home\database\INITtestdb.ora’ from ‘備份路勁’；也可以恢復pfile，然後去修改相應的參數
6、恢復控制文件(从current controlfile的备份文件恢复)
Restore controlfile from ‘備份路勁’
恢復出控制文件，并使用控制文件把資料庫切換為mount狀態。
alter database mount；
7、restore database;
源库的数据文件放置的位置为'D:\APP\H2603027\ORADATA\TESTDB\SYSTEM01.DBF'，现在异机不同目录恢复到'D:\APP\administrator\ORADATA\TESTDB\SYSTEM01.DBF'
run
{
set newname for datafile 1 to 'D:\APP\administrator\ORADATA\TESTDB\SYSTEM01.DBF';
set newname for datafile 3 to 'D:\APP\administrator\ORADATA\TESTDB\UNDOTBS01.DBF';
set newname for datafile 2 to 'D:\APP\administrator\ORADATA\TESTDB\SYSAUX01.DBF';
set newname for datafile 5 to 'D:\APP\administrator\ORADATA\TESTDB\TEST.DBF';
set newname for datafile 4 to 'D:\APP\administrator\ORADATA\TESTDB\USERS01.DBF';
restore database; --只是将RMAN文件还原到上面指定的位置
switch datafile all; --如果不交换，则recover时，仍会在原来的位置找该文件 } 8、recover database 可以通过recover database preview来查看消除数据库恢复的模糊性； 通过catalog archivelog来指定恢复的最新的归档日志； 然后recover database。 或者根据list backup中的scn修复数据库 備份集 12 中的存檔日誌清單 繫線順序 低 SCN Low Time 下一個 SCN 下一次時間 ---- ------- ---------- ---------- ---------- --------- 1 73 959379 18-11月-14 959769 18-11月-14 1 74 959769 18-11月-14 959781 18-11月-14 rman>recover database until scn 959769; 9、rman>alter database open resetlogs 在此步骤之前，首先建立与源数据库相同的日志文件放置的位置，把日志文件和临时文件放置在那里，然后通过修改控制文件把日志文件和临时文件放置在和数据文件相同的位置。 10、修改控制文件 控制文件对于数据库来说是非常重要的数据结构，在进行数据恢复时通常是必不可少的. Oracle提供两种方式备份控制文件: 1.生成可以重建控制文件的脚本 2.备份二进制的控制文件 我们看一下如何获得可以重建控制文件的脚本. Oracle提供如下命令: alter database backup controlfile to trace; 实际操作: sql> alter database backup controlfile to trace; Database altered. sql> show parameter user_dump_dest; NAME TYPE ------------------------------------ ---------------------- VALUE ------------------------------ user_dump_dest string D:\app\H2603027\diag\rdbms\tes tdb\testdb\trace trace文件内容: -- The following are current System-scope REDO Log Archival related -- parameters and can be included in the database initialization file. -- -- LOG_ARCHIVE_DEST='' -- LOG_ARCHIVE_DUPLEX_DEST='' -- -- LOG_ARCHIVE_FORMAT=ARC%S_%R.%T -- -- DB_UNIQUE_NAME="testdb" -- -- LOG_ARCHIVE_CONFIG='SEND,RECEIVE,NODG_CONFIG' -- LOG_ARCHIVE_MAX_PROCESSES=4 -- STANDBY_FILE_MANAGEMENT=MANUAL -- STANDBY_ARCHIVE_DEST=%ORACLE_HOME%\RDBMS -- FAL_CLIENT='' -- FAL_SERVER='' -- -- LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST' -- LOG_ARCHIVE_DEST_1='MANDATORY NOREOPEN NODELAY' -- LOG_ARCHIVE_DEST_1='ARCH NOAFFIRM EXPEDITE NOVERIFY SYNC' -- LOG_ARCHIVE_DEST_1='NOREGISTER NOALTERNATE NODEPENDENCY' -- LOG_ARCHIVE_DEST_1='NOMAX_FAILURE NOQUOTA_SIZE NOQUOTA_USED NODB_UNIQUE_NAME' -- LOG_ARCHIVE_DEST_1='VALID_FOR=(PRIMARY_ROLE,ONLINE_LOGFILES)' -- LOG_ARCHIVE_DEST_STATE_1=ENABLE -- -- Below are two sets of sql statements,each of which creates a new -- control file and uses it to open the database.
