sqlnet.ora里面的sqlnet.authentication_services设置错误导致sqlplus “/as sysdba“登录失败

将sqlnet.ora里面的
sqlnet.authentication_services=（tcps)
导致没有了操作系统认证这种登录方法
所以sqlplus "/as sysdba"会报错

./sqlplus “/as sysdba”

srvctl stop database /stop instance也无法运行 报错
因为srvctl依赖 操作系统认证这种登录方式

./srvctl stop database -d cdb1 -f
