Oracle数据文件迁移知多少？

本人以前整理的数据库文件迁移过程，希望能够对大家有所帮助

1、sqlplus "sys/sys@服务名 as sysdba"

2、修改控制文件:

alter system set control_files='E:/oracle/oradata/myOracle_1/control01.ctl',
'E:/oracle/oradata/myOracle_1/control02.ctl','E:/oracle/oradata/myOracle_1/control03.ctl'
scope=spfile;
3、备份控制文件
alter database backup controlfile to 'E:/oracle/oradata/testdb.ctl' reuse;
4、备份到跟踪文件, 方便重建控制文件
alter database backup controlfile to trace;
6、查看存放路径
show parameter user_dump_dest

6、数据文件拷贝到对应的目录:

7、到对应的ORACLE的数据目录 user_dump_des,找到对应的最新的TRACE文件，拷贝对应的数据出来：
内容如下：
1、重做日志文件可用的情况
STARTUP NOMOUNT;

CREATE CONTROLFILE REUSE DATABASE "MYORACLE" NORESETLOGS NOARCHIVELOG
-- SET STANDBY TO MAXIMIZE PERFORMANCE
MAXLOGFILES 3
MAXLOGMEMBERS 3
MAXDATAFILES 20
MAXINSTANCES 1
MAXLOGHISTORY 226
LOGFILE
GROUP 1 'E:/ORACLE/ORADATA/MYORACLE_1/REDO01.LOG' SIZE 30M,
GROUP 2 'E:/ORACLE/ORADATA/MYORACLE_1/REDO02.LOG' SIZE 30M,
GROUP 3 'E:/ORACLE/ORADATA/MYORACLE_1/REDO03.LOG' SIZE 30M
-- STANDBY LOGFILE
DATAFILE
'E:/ORACLE/ORADATA/MYORACLE_1/SYSTEM01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/UNDOTBS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/DRSYS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/INDX01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/TOOLS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/USERS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/XDB01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/PERFSTAT.ORA'
CHARACTER SET ZHS16GBK;

alter database rename file 'E:/ORACLE/ORADATA/MYORACLE/system01.dbf' to 'E:/ORACLE/ORADATA/MYORACLE_1/system01.dbf';

recover database until cancel using backup controlfile;

ALTER DATABASE OPEN;

2、重做日志文件不可用的情况

STARTUP NOMOUNT;

CREATE CONTROLFILE REUSE DATABASE "MYORACLE" RESETLOGS NOARCHIVELOG
-- SET STANDBY TO MAXIMIZE PERFORMANCE
MAXLOGFILES 3
MAXLOGMEMBERS 3
MAXDATAFILES 20
MAXINSTANCES 1
MAXLOGHISTORY 226
LOGFILE
GROUP 1 'E:/ORACLE/ORADATA/MYORACLE_1/REDO01.LOG' SIZE 30M,
GROUP 2 'E:/ORACLE/ORADATA/MYORACLE_1/REDO02.LOG' SIZE 30M,
GROUP 3 'E:/ORACLE/ORADATA/MYORACLE_1/REDO03.LOG' SIZE 30M
-- STANDBY LOGFILE
DATAFILE
'E:/ORACLE/ORADATA/MYORACLE_1/SYSTEM01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/UNDOTBS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/DRSYS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/INDX01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/TOOLS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/USERS01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/XDB01.DBF',
'E:/ORACLE/ORADATA/MYORACLE_1/PERFSTAT.ORA'
CHARACTER SET ZHS16GBK;

recover database until cancel using backup controlfile;

ALTER DATABASE OPEN RESETLOGS
