數(shù)據(jù)庫中如何使用SET NEWNAME FOR

這篇文章主要介紹了數(shù)據(jù)庫中如何使用SET NEWNAME FOR，具有一定借鑒價值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。

SET NEWNAME FOR后面必須帶SWITCH DATAFILE ALL或SWITCH TEMPFILE ALL
RUN {
SET NEWNAME FOR DATAFILE 1 to '/oracle/ora11g/oradata/system01.dbf';
SET NEWNAME FOR DATAFILE 2 to '/oracle/ora11g/oradata/sysaux01.dbf';
SET NEWNAME FOR DATAFILE 3 to '/oracle/ora11g/oradata/undotbs01.dbf';
SET NEWNAME FOR DATAFILE 4 to '/oracle/ora11g/oradata/users01.dbf';
SET NEWNAME FOR DATAFILE 5 to '/oracle/ora11g/oradata/undotbs02.dbf';
SET NEWNAME FOR DATAFILE 6 to '/oracle/ora11g/oradata/test01.dbf';
SET NEWNAME FOR TEMPFILE 1 to '/oracle/ora11g/oradata/temp01.dbf';
RESTORE DATABASE;
SWITCH DATAFILE ALL;
SWITCH TEMPFILE ALL;
}

run{
set newname for datafile '/MM/DataYY.dbf' to '/NN/DataYY.dbf';
set newname for tempfile '/MM/TempYY.dbf' to '/NN/TempYY.dbf';
restore database;
switch datafile all;
switch tempfile all;
}
MM是原路徑，NN是新路徑



只轉(zhuǎn)換DATAFILE時如下
run{
set newname for datafile '/MM/DataYY.dbf' to '/NN/DataYY.dbf';
restore database;
switch datafile all;
}



switch datafile all、switch tempfile all的作用就是在控制文件里面把數(shù)據(jù)文件路徑改過了
If you need to restore a data file to a new location, then use the RMAN SET NEWNAME command within a RUN command to specify the new file name. Afterward, use a SWITCH DATAFILE ALL command, which is equivalent to using the SQL statement ALTER DATABASE RENAME FILE, to update the control file to reflect the new names for all data files for which a SET NEWNAME has been issued in the RUN command.
