1.操作系统已经安装unixODBC环境
1.查看操作系统上查看ODBC版本
[dmdba@localhost]# odbc_config --version
2.3.0
2.查看ODBC配置文件存放的位置
[root@localhost etc]# odbc_config --odbcini
/etc/odbc.ini
[root@localhost etc]# odbc_config --odbcinstini
/etc/odbcinst.ini
3.修改odbc.ini文件
[dmdba@localhost]# vi /etc/odbc.ini
[dm]
Description = DM ODBC DSN
Driver = DM7 ODBC DRIVER
SERVER = localhost
UID = SYSDBA
PWD = SYSDBA
TCP_PORT = 5236
4.修改odbcinst.ini文件
[dmdba@localhost]# vi /etc/odbcinst.ini
[DM7 ODBC DRIVER]
Description = ODBC DRIVER FOR DM7
Driver = /opt/dmdbms/bin/libdodbc.so
5.测试连接
[root@localhost]# disql dm SYSDBA SYSDBA
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+
2. 操作系统未安装unixODBC环境
1.将附件unixODBC-2.3.0.tar.gz上传到/usr/local下，执行安装。
[root@localhost local]# tar -xzvf unixODBC-2.3.0.tar.gz
[root@localhost unixODBC-2.3.0]# cd unixODBC-2.3.0
[root@localhost unixODBC-2.3.0]# ./configure --enable-gui=no
[root@localhost unixODBC-2.3.0]# make
[root@localhost unixODBC-2.3.0]# make install
2.查看操作系统上查看ODBC版本
[dmdba@localhost]# odbc_config --version
2.3.0
3.查看ODBC配置文件存放的位置
[root@localhost etc]# odbc_config --odbcini
/etc/odbc.ini
[root@localhost etc]# odbc_config --odbcinstini
/etc/odbcinst.ini
4.修改odbc.ini文件
[dmdba@localhost]# vi /etc/odbc.ini
[dm]
Description = DM ODBC DSN
Driver = DM7 ODBC DRIVER
SERVER = localhost
UID = SYSDBA
PWD = SYSDBA
TCP_PORT = 5236
5.修改odbcinst.ini文件
[dmdba@localhost]# vi /etc/odbcinst.ini
[DM7 ODBC DRIVER]
Description = ODBC DRIVER FOR DM7
Driver = /opt/dmdbms/bin/libdodbc.so
6.测试连接
[root@localhost]# disql dm SYSDBA SYSDBA
+---------------------------------------+
| Connected! |

| sql-statement |
| help [tablename] |
| quit |
