【ORACLE】监听程序当前无法识别连接描述符中请求的服务-处理方法

来源：互联网发布：联合国数据库编辑：程序博客网时间：2024/05/22 02:27

在listener.ora和tnsnames.ora这两个文件中

首先：listener.ora的基本信息应该是：

listener.ora
# listener.ora Network Configuration File: F:/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = F:/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
     (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = F:/oracle/product/10.2.0/db_1)
      (SID_NAME = orcl)
    )

)

LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
)
出现“监听程序当前无法识别连接描述符中请求的服务”一般是因为缺少了上面中间位置的

(SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = F:/oracle/product/10.2.0/db_1)
      (SID_NAME = orcl)
    )
只要把它加在上面就行了。。。

tnsnames.ora
# tnsnames.ora Network Configuration File: F:/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
)
