Informatica连接Mysql，需要用到unix下的ODBC，以及Mysql的odbc_connector。
下载安装文件
unixODBC-2.3.0.tar.gz
mysql-connector-odbc-5.1.8-1.rhel5.i386.rpm
一.安装unixODBC
tar -xzf unixODBC-2.3.0.tar.gz
cd unixODBC-2.3.0
./configure --prefix=/usr/local/unixODBC --includedir=/usr/include --libdir=/usr/lib -bindir=/usr/bin --sysconfdir=/etc
make
make install
安装成功后，unixODBC所需的头文件都被安装到了/usr/inlucde下，编译好的库文件安装到了/usr/lib下，与unixODBC相关的可执行文件安装到了/usr/bin下，配置文件放到了/etc下。
或者
rpm -ivh unixODBC-2.2.11-7.1.i386.rpm
unixODBC-devel-2.2.11-7.1.i386.rpm
二.安装mysql-connector-odbc
rpm -ivh mysql-connector-odbc-5.1.8-1.rhel5.i386.rpm --nodeps
(- -nodeps)为忽略依赖关系。
三.配置myodbc
vi /etc/odbc.ini
[mysql-test]
Description = MySQL test database
Trace = On
TraceFile = stderr
Driver = mysql
SERVER = localhost
USER = root
PASSWORD = kaychen
PORT = 3306
DATABASE = test
socket = /tmp/mysql.sock
vi /etc/odbcinst.ini
[PostgreSQL]
Description = ODBC for PostgreSQL
Driver = /usr/lib/libodbcpsql.so
Setup = /usr/lib/libodbcpsqlS.so
FileUsage = 1
[MySQL ODBC 5.1 Driver]
Driver = /usr/lib/libmyodbc5.so
UsageCount = 1
[mysql]
Description = MySQL driver
Driver = /usr/lib/libmyodbc5.so
Setup = /usr/lib/libodbcmyS.so
Socket = /tmp/mysql.sock
FileUsage = 1
测试连接：isql mysql-test 或者isql mysql-test root
