需要远程连接的oracle服务器的版本是：

linux.x64_11gR2_database_1of2.zip

linux.x64_11gR2_database_2of2.zip

Linux 系统：CentOS 5.5

 

PLSQL版本为：PL/SQL Developer Version 8.0.1.1502

注册信息如下
product code：kfqtle46lqzbbvlzuvsrutst66yn6m7kl8s2trrtsapr
password：xs374ca
serial number：1775341736

 

Oracle客户端需要的软件均可以从官方网站下载：

instantclient-basic-win32-11.2.0.1.0.zip

instantclient-jdbc-win32-11.2.0.1.0.zip

instantclient-sqlplus-win32-11.2.0.1.0.zip

将这三个文件直接解压即可，完成以后是所有文件都在一个文件夹下面，我这里解压之后的文件夹名称是：oracleinstantclient_11_2

 

第一步：将此文件夹放在d盘，其他盘也可以，现在路径是：D:\oracleinstantclient_11_2

 

第二步：配置环境变量，在系统环境变量里面加入：

Path          D:\oracleinstantclient_11_2

TNS_ADMIN    D:\oracleinstantclient_11_2

NLS_LANG     AMERICAN_AMERICA.UTF8

 

第三步：创建配置文件：tnsnames.ora

内部内容如下：

ORCL =

 (DESCRIPTION =

  (ADDRESS_LIST =

                 (ADDRESS =(PROTOCOL = TCP)(HOST = 159.226.2.207)(PORT = 1521))

        )

        (CONNECT_DATA =

          (SERVICE_NAME = orcl)

        )

 )

 

其中orcl为服务器监听的服务名称，可使用命令查询：

[zhang@zhangshibo ~]$ lsnrctl

Welcome to LSNRCTL, type "help" for information.

服务器端监听文件只和listener.ora有关，只需配置好此文件即可，内容为：

# listener.ora Network Configuration File: /home/zhang/app/zhang/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = 159.226.2.207)(PORT = 1521))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      )
    )
  )
SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /home/zhang/app/zhang/product/11.2.0/dbhome_1)
      (SID_NAME = orcl)
    )
  )

ADR_BASE_LISTENER = /home/zhang/app/zhang

 

 

第四步：配置PL/SQL，如下：

Tools-》Preferences-》Oracle下面的Connection变量设置为：

Oracle  Home     D:\oracleinstantclient_11_2

OCI  library         D:\oracleinstantclient_11_2\oci.dll

 

第五步：打开PL/SQL，登录即可！

 

需要注意的地方：服务器版本和客户端版本要一致！配置完环境变量以后，重启机器！
