报错：

ORA-01516: nonexistent log file, data file, or temporary file

ORA-65054: Cannot open a pluggable database in the desired mode.

ORA-01109: database not open



ERROR at line 1:

ORA-01157: cannot identify/lock data file 13 - see DBWR trace file

ORA-01110: data file 13: '/oradata/esb/system01.dbf'



ERROR at line 1:

ORA-01516: nonexistent log file, data file, or temporary file

"/oradata/esb/system01.dbf" in the current container

错误挺多的，最后还是因为没有弄清cdb和pdb，如果需要把损坏的dbf文件下线，需要切换到Pdb库里面才能进行drop操作。

切记切记。

SQL> alter database open;
