关于今天装oracle之后用工具链接时的问题

来源：互联网发布：北京学java最好的学校编辑：程序博客网时间：2024/05/16 15:51

首先两个工具我都试了，一个是plsql 另一个就是navicat

下面记录一下两个的解决办法

两个都需要先下载一个中间件可以在oracle官网下载我已经在csdn上上传一个了，

连接地址为http://download.csdn.net/detail/top_y/9607430 大家可以直接下载，无需积分

在navicat中首先是要把下载的中间件解压出来，之后打开navicat

后缀名是oci.ddl的文件即可，然后修改oracle安装目录下product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora文件源文件为

# listener.ora Network Configuration File: D:\app\admin\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\admin\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\admin\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
)

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

ADR_BASE_LISTENER = D:\app\admin

修改为

# listener.ora Network Configuration File: D:\app\admin\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = D:\app\admin\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\admin\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
   (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = d:\app\Administrator\product\11.2.0\dbhome_1)
      (SID_NAME = orcl)
    )
)

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

ADR_BASE_LISTENER = D:\app\admin

红色部分为修改部分，然后开始建立连接即可

plsql则需要把文件解压到oracle安装目录下product\11.2.0文件夹平级的地方

然后把oracle中的tnsnames.ora文件复制到instantclient_11_2文件夹下面

之后打开plsql

将解压的中间件路径填到对应位置，重启plsql即可
