前言

先赞后看,此生必赚!

每次安装oracle以后,都会出现使用plsql连接不上的问题!多次重启电脑、重装系统的磨人经历之后,

今天看到这篇文章算是你我之幸!希望能帮助广大技术人员减少一些时间,顺利进行连接!

注:也可以用plsql连接远程数据库(只要有oracle的network\admin\tnsnames.ora就行)。

首先下载64位oracle以及32位轻量级客户端(注意版本的对应,我用的是11g的oracle和11.2的客户端):

点击进入oracle下载页面 点击进入客户端下载页面

以下步骤请自行更改路径,不然,出错了别怪我哦:

step1 复制network文件

oracle安装到某路径下,安装步骤很简单,网上可以搜到!

客户端随便解压到一个路径,我的是放在d:\app\shuhao\instantclient_11_2了。

然后把oracle中的d:\app\shuhao\product\11.2.0\dbhome_1里面的整个network文件夹复制,

粘贴到客户端文件夹d:\app\shuhao\instantclient_11_2下面,如下图所示:

step2 修改配置文件

2.1 修改oracle数据库文件

d:\app\shuhao\product\11.2.0\dbhome_1\network\admin\listener.ora文件内容,添加一个sid_desc:

# listener.ora network configuration file: d:\app\shuhao\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\shuhao\product\11.2.0\dbhome_1)
      (program = extproc)
      (envs = "extproc_dlls=only:d:\app\shuhao\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
#下面的sid_desc是新增加的内容,注意修改oracle_home路径
    (sid_desc =
      (sid_name = orcl)
      (oracle_home = d:\app\shuhao\product\11.2.0\dbhome_1)
      (global_dbname = orcl)
    )
  )
 
listener =
  (description_list =
    (description =
      (address = (protocol = tcp)(host = localhost)(port = 1521))
    )
  )
 
adr_base_listener = d:\app\shuhao

2.2 修改oracle数据库文件

d:\app\shuhao\product\11.2.0\dbhome_1\network\admin\tnsnames.ora文件内容,源文件没有做改动:

# tnsnames.ora network configuration file: d:\app\shuhao\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# generated by oracle configuration tools.
 
oraclr_connection_data =
  (description =
    (address_list =
      (address = (protocol = tcp)(host = localhost)(port = 1521))
    )
    (connect_data =
      (service_name = orcl)
    )
  )
 
listener_orcl =
  (address = (protocol = tcp)(host = localhost)(port = 1521))
 
orcl =
  (description =
    (address = (protocol = tcp)(host = localhost)(port = 1521))
    (connect_data =
      (server = dedicated)
      (service_name = orcl)
    )
  )

2.3 修改客户端文件

d:\app\shuhao\instantclient_11_2\network\admin\tnsnames.ora文件内容:

# tnsnames.ora network configuration file: d:\app\shuhao\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# generated by oracle configuration tools.
 
oraclr_connection_data =
  (description =
    (address_list =
      (address = (protocol = tcp)(host = localhost)(port = 1521))
    )
    (connect_data =
      (service_name = orcl)
    )
  )
 
listener_orcl =
  (address = (protocol = tcp)(host = localhost)(port = 1521))
 
orcl =
  (description =
    (address = (protocol = tcp)(host = localhost)(port = 1521))
    (connect_data =
      (server = dedicated)
      (service_name = orcl)
    )
  )
#新增 @ 标识符,用于区分本地与远程oracle
orcl@192.168.0.164 =
  (description =
    (address = (protocol = tcp)(host = 192.168.0.164)(port = 1521))
    (connect_data =
      (server = dedicated)
      (service_name = orcl)
    )
  )

step3 配置oci

不登录plsql,直接按cancel,进入后在tools--->preferences---->connection中配置oci为32位客户端的oci

d:\app\shuhao\instantclient_11_2\oci.dll

step4 环境变量配置

添加前2个系统变量:

1. 变量名:tns_admin

变量值:d:\app\shuhao\instantclient_11_2\network\admin

2. 变量名:nls_lang

变量值:simplified chinese_china.zhs16gbk

3. path中配置加入:

d:\app\shuhao\product\11.2.0\dbhome_1\bin;d:\app\shuhao\instantclient_11_2;

step5 重启电脑(有时候不需要重启)

启动oracle服务与监听,这个就不需要描述了。

step6 登录plsql!!!

当看到database下拉框中有本地的orcl以及远程的orcl@192.168.0.164就算成功了!!!
