在连接sqldeveloper出现的异常信息

ORA-12505, TNS:listener does not currently know of SID given in connect descriptor （二） 异常及解决 后记

在ORA-12505, TNS:listener does not currently know of SID given in connect descriptor中我已解决了该问题（通过设置listener.ora和配置环境变量），listener.ora一直是默认配置都没有问题，今天却又碰到此问题。

下面的listener.ora的默认配置

# listener.ora Network Configuration File: D:oracle11gproduct11.2.0dbhome_1
etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:oracle11gproduct11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:oracle11gproduct11.2.0dbhome_1inoraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:oracle11g

解决：

增加一个SID_DESC ，如下：（红色为新增）

# listener.ora Network Configuration File: D:oracle11gproduct11.2.0dbhome_1
etworkadminlistener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:oracle11gproduct11.2.0dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:oracle11gproduct11.2.0dbhome_1inoraclr11.dll")
    )
    (SID_DESC =
      (GLOBAL_DBNAME = ORCL)
      (ORACLE_HOME = D:oracle11gproduct11.2.0dbhome_1)
      (SID_NAME = ORCL)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

ADR_BASE_LISTENER = D:oracle11g

OK

后记

为什么本来默认的就没问题，今天就不行了？
