Install Oracle 11g R2 on Ubuntu

Ubuntu is not an official supported linux version from Oracle, so I still get some errors during the install process even with required configuration, anyway, it can work and what i'm doing here is try to setup an experiment environment, it's enough to me, any one who want to deploy Oracle in product mode should have supported linux platform like RedHat, OK, following is the steps i have to install it:

1. If you were in multihomed enviroment, set the ORACLE_HOSTNAME variable:
    export ORACLE_HOSTNAME=machine_name.domain_name

2. Create create OSDBA (dba) group, Oracle Inventory group (oinstall)  and a user "oracle" which has "dba" as its login group and oinstall as its 2nd group.

3. Modify /etc/sysctl.conf, set kernel parameter:

4. Modify /etc/security/limits.conf to improve the "number of process" and "number of open file"  performance for oracle:

5. Modify /etc/pam.d/login, add:

6. Modify /etc/profile:

7. Change user to oracle if you haven't done it yet

8. Create base directory, for me it's "/app/oracle"

9. Export ORACLE_BASE, ORACLE_SID

10.  If you're trying to install oracle with a X window:

11. run installer:

12. Oracle should start, if the installer GUI cannot be start, check the error messages, most time it's because a wrong X window configuration, if you are running X window with Xming, just like me, please do make sure to check the "No Access Control" check box in the launch, otherwise, Xming will reject the connection.

13. Now the GUI shoudl open, like what you did in the Windows system, fullfill required value and click next, ingore all errors if there is any condition that is not match, click finish in the last step, it should start install process.

14. After install oracle, the installer GUI will ask you to run two .sh files, run it with a root role.

15. You can try to visit https://you.ip.address:1158/em to see is that OK for you.

16. How to start oracle:

9. If bad luck with you, click right-upper corner, there is a connection configuration menu, you can create "Mobile Broadband" connection yourself here, don't forget input the phone number "#777" (for China Telcom) and your username password, after that click connect, this works for me.
