使用PL/SQL连接别人的Oracle . 1、下载Instant Client
Oracle官网地址:http-://www.-oracle.-com/technetwork/database/features/instant-client/index-097480.html
下载后是一个压缩文件,解压后的文件叫instantclient_11_2,放在自己喜欢的目录,如:D:/instantclient_11_2
2、D:/instantclient_11_2目录下新建目录network,在network目录下再新建目录admin,在admin目录下新建tnsnames.ora,
使用文本编辑器输入如下内容:
[plain] view plaincopyprint? 01.MyOracle = 02. (DESCRIPTION = 03. (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.1.4)(PORT = 1521)) 04. (CONNECT_DATA = 05. (SERVER = DEDICATED) 06. (SERVICE_NAME = orcl) 07. ) 08. ) MyOracle = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.1.4)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) ) 修改自己的本地主机名和远程数据库实例名
3、添加一个环境变量,名为TNS_ADMIN,值为tnsnames.ora文件所在路径。比如我的本机为:D:/instantclient_11_2/network/admin
4、设置ORACLE的语言,添加环境变量NLS_LANG ,值为SIMPLIFIED CHINESE_CHINA.ZHS16GBK
5、下载并安装PL.SQL.Developer配置应用
配置tools->preferences->connection
Oracle Home D:/instantclient_11_2 OCI library D:/instantclient_11_2/oci.dll
6、关闭PL/SQL Developer,重起Developer. 主机名就会出现在PL/SQL Developer的列表里,输入用户名密码,就可以登录远程oracle 11g数据库了。
