参数文件中log_file_name_convert或db_file_name_convert参数如果有多条记录不能分开写，因此上面这种写法是错误的，需要写在同一行上，如下所示:
*.log_file_name_convert=('+DATA/mydb/onlinelog','/opt/Ora11gData/ora11g','+FRA/mydb/onlinelog','/opt/Ora11gData/ora11g')
*.db_file_name_convert=('+DATA/mydb/datafile','/opt/Ora11gData/ora11g','+DATA/mydb/tempfile','/opt/Ora11gData/ora11g')
