I wrote this post from mobile phone while coming from office so it is thoughts coming on wheel.

Setting up database connectivity from oracle(10.2.0.4 on RHEL 5.3 64bit) to foreign data source(any odbc compliant database mysql, mssql server, postgres, netezzza )

What softwares you need to have:

-11g Gateway (if connecting to mysql needs patched to 11.1.0.7) or 11.2.0.1 gateway w
-ODBC Driver Manager (download from unixodbc.org)
-ODBC driver [provided by DB vendor or third party like Data Direct technologies]
- 10g software should have interim patch ******* installed for some bugs for mysql.

Here is steps outline:

1. install ODBC Driver Manager [ need check it is right version]
2. install mysql connector [ need check it is right version]
3. prepare /etc/odbc.ini [location given by env variable
and /etc/odbcinst.ini [location given by odbcinst -j -q]
export NZ_ODBC_INI_PATH=/etc
export ODBCSYSINI=/etc
export ODBCINI=/etc/odbc.ini

4. prepare DSN file
5. check connect from isql [dsn_name] -v
6. install oracle gateway
7. preparare initINSTANCENAME.ora in gateway/hs/admin
8. prepare gateway listener with librarries specified in envs
9. start gateway listener
10. create tnsname which addresses to gateway listener
11. create dblink using tnsname name created in 9.
12. test dblink with various cases

Config files you need to create:

1. Odbc.ini and odbcinst.ini for odbc connectivitt.
2. initDG4ODBC.ora in 11g gateway home/hs/admin
3.
