How to conncet mysql database and oracle database 11g2 on linux 5.4

Question

Hi,
Can anyone help me to connect mysql server database to Oracle
database on Linux OS?
I have done all things, but I am getting a problem in installing dg4odbc
driver on Oracle database. In a simple word, I don't know how to create
listener between mysql database and Oracle database.
If anyone knows that please help me in configuring dg4odbc for Oracle. OS
-Linux 5.4 and refer any doc or link.
oracle 11g2 11.2.0.1
i follow the metalink id - 466228.1 ( but cant successed).
Thanks and regards,

hi pl z clear me it is required to install manully the dg4odbc driver for oracle to connect MySQL server database. because in my $ORACLE_HOME/hs/admin/initdg4odbc.ora is present automatically.
details of the initdg4odbc.ora
# This is a sample agent init file that contains the HS parameters that are
# needed for the Database Gateway for ODBC
# HS init parameters
HS_FDS_CONNECT_INFO = mysql_odbc
HS_FDS_TRACE_LEVEL = off
HS_FDS_SHAREABLE_NAME = /usr/lib/libmyodbc5w.so
# ODBC specific environment variables
set ODBCINI=/etc/odbc.ini
set LD_LIBRARY_PATH=/usr/lib
# Environment variables required for the non-Oracle system
#set HOME=/home/oracle
