Oracle DB 12c 连接问题

Question

我正面临 Oracle DB 12c 连接问题，并出现下面提到的错误。

ORA-12505，TNS:listener 目前不知道在 连接描述符

显示下面发布的错误消息的屏幕截图。

Oracle配置工具生成的tnsnames.ora文件内容贴在下面。

LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))


ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1588))
    )
    (CONNECT_DATA =
      (SID = CLRExtProc)
      (PRESENTATION = RO)
    )
  )

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

PDBORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = pdborcl)
    )
  )

Answer 1

您在SID 项目中输入了ORADIM。您的 TNSNAMES.ORA 中没有名为“ORADIM”的数据库。

如果我是你，我会尝试

• ORCL 或
• PDBORCL

输入SERVICE_NAME。
