新建控制文件失败，求大神解答，谢谢！

新建controlfile 脚本如下：
create controlfile reuse database orcl archivelog noresetlogs
maxlogfiles 16
maxinstances 8
maxlogmembers 3
maxloghistory 1
datafile
'/oracle/oradata/orcl/example01.dbf',
'/oracle/oradata/orcl/system01.dbf',
'/oracle/oradata/orcl/sysaux01.dbf',
'/oracle/oradata/orcl/users01.dbf',
'/oracle/oradata/orcl/undotbs01.dbf'
character set utf8
提示错误如下：
SQL> @/oracle/ctctl.sql
create controlfile reuse database orcl archivelog noresetlogs
