配置环境

#c++ occi

exportLD_LIBRARY_PATH=$LD_LIBRARY_PATH:/u01/netbean/OCCI/instantclient_11_2

export DISPLAY=192.168.0.67:0.0

 

OK 这样运行NETBEANS后 就把图形界面导在WINDOWS下了,当然你得先开启Xmanager– Passive来接受

然后运行个HELLO WORD 来测试下NETBEANS C++ 运行环境

关于LINUX C++安装可以看看 http://blog.csdn.net/ZengMuAnSha/article/details/8141666

 

然后呢我们得把头文件和LIBS添加到NETBEAN环境中

 

 它在文件->项目属性中

我们把INCLUDE文件添加

 

添加LIBS 在连接器当中

 

我们把那个LIBOCCI.SO.11.1 得改名否则不会显示出来的. 要添加两个库

 

再然后呢就是输入代码

           env->terminateConnection(conn); 

           Environment::terminateEnvironment(env); 

           return 0; 

  } 

 我在WIN7上 IDE最大化的 菜单无法稳定下来.

 

构建完了后它IDE 会把项目放在/HOME/ORACLE目录下

运行时候报错

terminate called after throwing an instanceof 'oracle::occi::SQLException'

 what():  ORA-12154: TNS: 无法解析指定的连接标识符

运行 FINISHED; Aborted; 核心已转储; 实时:  140ms; 用户:  10ms; 系统:  10ms

 

监听和TNS配置都好好的

已使用的参数文件:

已使用 TNSNAMES 适配器来解析别名

尝试连接 (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = svr3)(PORT =1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.3)(PORT = 1521))(CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl)))

OK (20 毫秒)

[oracle@svr3 admin]

 

我们直接用TNSNAME

conn = env->createConnection(struser,strpwd, "orcl");

 

OK!! 小功告成
