PLSQL Developer连接远程oracle配置

在windows机器上不想安装oracle或者oracle的客户端，我们怎么使用PLSQL Developer工具呢？答案如下：

环境                       windows7  64bit

目标环境               centOS5.8  64bit

1：在oracle官网上下载instantclient-basic-nt-11.2.0.3.0.zip该文件，下载地址为：客户端。下载完成后解压该文件。如：我将其解压在E:\oracleClient\instantclient_11_2该路径下。进入到instantclient_11_2下创建目录NETWORK，然后再NETWORK下建立目录ADMIN。在ADMIN目录下建立tnsnames.ora文件，在该tnsnames.ora文件中添加如下内容：

[ruby] view plain copy print ?

1. ORACLR_CONNECTION_DATA =  
2.   (DESCRIPTION =  
3.     (ADDRESS_LIST =  
4.       (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))  
5.     )  
6.     (CONNECT_DATA =  
7.       (SID = CLRExtProc)  
8.       (PRESENTATION = RO)  
9.     )  
10.   )  
11.  
12. TEST =                    
13.   (DESCRIPTION =  
14.     (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.175)(PORT = 1521))  
15.     (CONNECT_DATA =  
16.       (SERVER = DEDICATED)  
17.       (SERVICE_NAME = orcl)  
18.     )  
19.   ) 

ORACLR_CONNECTION_DATA = 
  (DESCRIPTION = 
    (ADDRESS_LIST = 
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) 
    ) 
    (CONNECT_DATA = 
      (SID = CLRExtProc) 
      (PRESENTATION = RO) 
    ) 
  ) 

TEST =                   
  (DESCRIPTION = 
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.2.175)(PORT = 1521)) 
    (CONNECT_DATA = 
      (SERVER = DEDICATED) 
      (SERVICE_NAME = orcl) 
    ) 
  )

192.168.2.175--为数据库所在机器ip

2：环境变量的配置

打开环境变量设置添加TNS_ADMIN，值为tnsnames.ora所在路径。如本机为E:\oracleClient\instantclient_11_2\NETWORK\ADMIN\tnsnames.ora

设置ORACLE的语言，添加环境变量NLS_LANG，值为AMERICAN_AMERICA.AL32UTF8  如果出现乱码可用SIMPLIFIED CHINESE_CHINA.ZHS16GBK
3：下载并安装PLSQL Developer

安装完成后进入PLSQL Developer，选择tools->preferences->connection

Oracle Home            

E:\oracleClient\instantclient_11_2

OCI library

E:\oracleClient\instantclient_11_2\oci.dll

修改完毕后保存并重启PLSQL Developer就可以使用该工具了。
