Oracle用RMAN还原种子数据库

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;
