例五 用switch datafile all更新表空间所有数据位置和名字
语句：
run{
sql 'alter tablespace pos offline immediate';
set newname for datafile '/oracle/CRM/test/POS5.dbf' to '/oracle/CRM/pos1.dbf';
set newname for datafile '/oracle/CRM/test/POS9.dbf' to '/oracle/CRM/pos2.dbf';
restore tablespace pos;
switch datafile all;
recover tablespace pos;
sql 'alter tablespace pos online';
}
执行过程如下：
RMAN> run{
2> sql 'alter tablespace pos offline immediate';
3>
set newname for datafile '/oracle/CRM/test/POS5.dbf' to '/oracle/CRM/pos1.dbf';
4> set newname for datafile '/oracle/CRM/test/POS9.dbf' to '/oracle/CRM/pos2.dbf';
5> restore tablespace pos;
6> switch datafile all;
7> recover tablespace pos;
8> sql 'alter tablespace pos online';
9> }
sql statement: alter tablespace pos offline immediate
