OracleXE安装和权限问题
参考资料：
我正在尝试安装/配置的产品: OracleXE 18c
问题1:
如安装指南中所述，尝试登录将返回如下所示的错误：
sqlplus / as sysdbaORA-12560: TNS:协议适配器错误
问题2:
以下命令在请求密码之前立即失败：
sqlplus system@localhost:1521/XEPDB1 ERROR:
ORA-01017: invalid username/password; logon denied
Enter user-name: system
Enter password:
ERROR:
ORA-12560: TNS:protocol adapter error 问题3:
正如本文顶部引用的参考问题之一所提到的那样，我尝试了ALTER PLUGGABLE DATABASE ALL OPEN;。命令成功完成。但是，像前面提到的那样尝试运行STARTUP会导致一个错误：
SQL> startup;
ORA-01031: insufficient privileges
ORA-01078: failure in processing system parameters
SQL>在windows命令提示符下运行whoami将返回我的用户名，该用户名具有管理私密性，与安装OracleXE的用户名相同。
附加背景：
我可以按以下方式登录：
sqlplus system@localhost:1521当我安装Oracle时，它使用tnsnames.ora和listner.ora作为主机创建了mymachine.mydomain.com。安装程序的完成屏幕告诉我使用localhost:1521登录，这是不工作的。经过几个小时的研究，我发现如果我将mymachine.mydomin.com改为localhost in tnsnames.ora和listener.ora，我可以以system@localhost:1521登录。然而，上述三个问题仍然存在。
如上面引用的票证所述，运行select value from v$parameter where name='service_names'只返回一行: XE。它还应该返回XEPDB1的一行吗？

- 问题1：
要在Windows上使用OS身份验证，您的用户应该在ORA_DBA组中，sqlnet.ora必须包含
SQLNET.AUTHENTICATION_SERVICES= (NTS)更新:我看到NTS已经配置好了，所以只需检查您是否在ORA_DBA组中。
- 问题2：
EZCONNECT：用//试试这个语法
sqlplus system@//localhost:1521/XEPDB1- 问题3：
你需要检查一下alert.log。您可以保存init参数并在这里发布参数：
alter system create pfile='c:/temp/init.ora' from spfile;然后发布这个文件并从alert.log中启动错误

如果您在通过sqlplus连接时省略了密码，则需要转义。这是我使用WindowsOS时的经验。我刚刚在我的MacOS上尝试了Easy，它在这里工作，不管是否逃跑。
REM password in clear text.
C:\>sqlplus user/password@host:port/SERVICE_NAME
REM you will be prompted for password
C:\>sqlplus user@"\host:port/SERVICE_NAME\"祝你好运！
