我在 Azure 上有 RHEL 6.8 Oracle 版本，我按照 Microsoft 的教程Create an Oracle Database in an Azure VMe安装了数据库。教程一切顺利。现在我尝试使用这个Oracle Application Express (APEX) 5.x 安装来安装 APEX，但我被困在了线上CONN sys@pdb1 AS SYSDBA。

输入密码后（不管它是否正确）我每次都得到ERROR: ORA-12154: TNS:could not resolve the connect identifier specified.

我已经尝试过：

  • 创建变量TNS_ADMIN
  • 添加ORACLE_HOME/network/admin到PATH
  • 创建和编辑文件：

监听器.ora：

# listener.ora Network Configuration File: /u01/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = OracleDbVm)(PORT = 1521))
  )

ADR_BASE_LISTENER = /u01/app/oracle

sqlnet.ora：

NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)

tnsnames.ora：

WINDOWNETSERVICE =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = OracleDbVm)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = cdb1)
    )
  )

lsnrctl 状态的输出

我还能做些什么来解决这个问题？

您CONN sys@pdb1 AS SYSDBA正在尝试使用 SID（或 tnsnames 条目）连接到实例pdb1，但在多租户环境中，您的所有数据库都共享相同的 SID（cdb1在您的情况下），并且您的 tnsnames 中没有pdb1条目。连接到 PDB 时，您需要在连接字符串中使用服务名称。

您可以像这样更新您的 tnsnames：

WINDOWNETSERVICE =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = OracleDbVm)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = cdb1)
    )
  )

pdb1=
  (DESCRIPTION=
    (ADDRESS=
      (PROTOCOL=TCP)
      (HOST=OracleDbVm)
      (PORT=1521)
    )
    (CONNECT_DATA=
      (SERVICE_NAME=pdb1)
    )
  )

然后再试CONN sys@pdb1 AS SYSDBA一次...

或者您可以尝试使用带有服务名称的完整连接字符串，例如：

conn sys@OracleDbVm:1521/pdb1 as sysdba

我想你也可以连接到 CDB，切换到 pdb1，然后启动脚本。如果您想了解有关该选项的更多详细信息，请告诉我。
