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。
