生成RMAN rename写法脚本

select  'set newname for datafile ' || x.FILE# || ' to ' ||  
       new_file_Location ||   substr(x.NAME,instr(x.name,'/',-1)+1 ,length(x.name)-instr(x.name,'/',-1))                  
  from v$datafile x,(select &new_loc new_file_Location from dual);

实验一下

Enter value for new_loc: '/home/oracle/'
old   3:   from v$datafile x,(select &new_loc new_file_Location from dual)
new   3:   from v$datafile x,(select '/home/oracle/' new_file_Location from dual)
