List of Temporary Files
=======================
File Size(MB) Tablespace Maxsize(MB) Tempfile Name
---- -------- -------------------- ----------- --------------------
1 60 TEMP 32767 /u01/app/oracle/oradata/scp/temp01.dbf
注意：restore 的时候不会对temp 表空间进行restore。所以等restore 之后，我们需要手工创建temp表空间。
J、为了将数据文件恢复到不同于原来的目录结构中，必须编写脚本，重新命名数据文件的位置，最后进行全库的恢复。
（如果数据文件路径和原来的相同则直接还原数据库）
run{
set newname for datafile 1 to '/home/OracleData/scp/system01.dbf';
set newname for datafile 2 to '/home/OracleData/scp/zytk_ac01.dbf';
set newname for datafile 3 to '/home/OracleData/scp/sysaux01.dbf';
set newname for datafile 4 to '/home/OracleData/scp/undotbs01.dbf';
set newname for datafile 5 to '/home/OracleData/scp/example01.dbf';
set newname for datafile 6 to '/home/OracleData/scp/users01.dbf';
set newname for datafile 7 to '/home/OracleData/scp/zytk_ac02.dbf';
set newname for datafile 8 to '/home/OracleData/scp/zytk_id01.dbf';
set newname for datafile 9 to '/home/OracleData/scp/zytk_id02.dbf';
set newname for datafile 10 to '/home/OracleData/scp/zytk_op01.dbf';
set newname for datafile 11 to '/home/OracleData/scp/zytk_op02.dbf';
set newname for datafile 12 to '/home/OracleData/scp/zytk_test01.dbf';
restore database;
switch datafile all;
}
对switch datafile all命令的说明：
--对于nocatalog 模式下，rman备份的信息是保存在控制文件里的，包括数据文件的路径信息。 这里的 switch datafile all 的作用，就是更新控制文件里的信息。如果不更新控制文件的话，则进行recover操作时还在原来的位置找文件。
K、还原数据库以后，进行 recover 操作
