Question

我想连接到正在运行的“ orcl” Oracle数据库。

我对Oracle管理员没有太多经验。我在Windows Server中安装了Oracle 12c，因为我在计算机中启动了“ Oracle”，“ OracleOraDB12Home1TNSListener”和“ OracleServiceORCL”服务。

我在“ tnsnames.ora”文件中添加了以下内容：

ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1539))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

执行“ tnsping orcl”命令会得到“确定”结果。

我可以使用“ sqlplus / as sysdba”登录，并且当我使用“从v $ database中选择名称”命令进行查询时，我看到“ orcl”数据库处于活动状态。

但是当我尝试使用Sqldeveloper连接到“ orcl”数据库时，或者当我执行

"sqlplus -L "system/password@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1539))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))"

我遇到了以下问题：

如何连接到orcl数据库？我在配置中或其他地方缺少什么？

Answer 1

我认为您想要的只是

sqlplus [user]/[Password]@[connect identifier]

例如您的用户为system，密码为pswd，示例中的连接标识符为'ORCL'

因此您的sqlplus命令将是：

sqlplus system/pswd@orcl

如果您的数据库已安装在本地计算机上，那么也可以只连接到本地主机而不是服务

sqlplus system/pswd@localhost

无法连接到Oracle服务
