oracle 12 C启动问题

启动时出现以下报错信息：

SQL> startup;
ORA-48146: missing read, write, or exec permission on directory during ADR initi
alization [D:\app\oracle\diag\rdbms\orcl] [0]
ORA-48187: specified directory does not exist
OSD-00002: ????????????
O/S-Error: (OS 5) ??????????

解决方案：

是因为权限问题，将diag目录赋于oracle权限即可
