Oracle DB 12c连接问题

Question

我正面临一个Oracle DB 12c连接问题，并带有以下提到的错误。

ORA-12505，TNS：侦听器当前不知道在连接描述符

显示以下错误消息的屏幕截图。

下面发布的Oracle配置工具生成的tnsnames.ora文件内容。

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ORADIM项目中输入了SID。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

进入SERVICE_NAME。
