发现是因为刚刚创建的表空间文件丢失，导致的。
开始修复表空间文件。

解决方法：
SQL> shutdown abort
ORACLE instance shut down.
SQL>

由于是表空间文件丢失，最后查看一下表空间：
SQL> 
SQL> select tablespace_name, file_name from dba_data_files;

TABLESPACE_NAME      FILE_NAME
-------------------- ----------------------------------------
EXAMPLE 	     /u01/app/oradata/orcl/example01.dbf
