起一个新实例名newdata
1、准备pfile
cp ...../dbs/init.ora ..../dbs/initnewdata.ora
vim initnewdata.ora
改变controlfile的位置
control_files=‘/u01/app/oracle/oradata/newdata/control.ctl‘
2、创建spfile
sqlplus / as sysdba
startup pfile=‘..../dbs/initnewdata.ora‘ nomount;
create spfile from pfile;
shutdown immediate;
startup nomount;
3、拷贝种子控制文件
cp /u01/app/oracle/product/10.2.0/db_1/assistants/dbca/templates/Seed_Database.ctl /u01/app/oracle/oradata/newdata
alter database mount;
4、拷贝种子数据文件备份片
cp /u01/app/oracle/product/10.2.0/db_1/assistants/dbca/templates/Seed_Database.dfb /u01/app/oracle/oradata/newdata
5、导入数据备份片信息到控制文件
rman
connect target /
delete noprompt backupset 1;
catalog start with ‘/u01/app/oracle/oradata/newdata/Seed_Database.dfb‘;
6、还原并恢复数据库
run {
set newname for datafile ‘/ade/b/2125410156/oracle/oradata/seeddata/system01.dbf‘ to ‘/u01/app/oracle/oradata/raw/system01.dbf‘;
set newname for datafile ‘/ade/b/2125410156/oracle/oradata/seeddata/sysaux01.dbf‘ to ‘/u01/app/oracle/oradata/raw/sysaux01.dbf‘;
set newname for datafile ‘/ade/b/2125410156/oracle/oradata/seeddata/undotbs01.dbf‘ to ‘/u01/app/oracle/oradata/raw/undotbs01.dbf‘;
set newname for datafile ‘/ade/b/2125410156/oracle/oradata/seeddata/usres01.dbf‘ to ‘/u01/app/oracle/oradata/raw/users01.dbf‘;
restore database;
recover database;
}
7、打开数据库
alter database open resetlogs;
