Currently I am testing Oracle Enterprise Linux (EL) to install Oracle EBS R12. I am on Linux preparation phase now. I am using EL 4 which is certified for Oracle EBS R12.
There was almost no problem with installation. The only problem was NIC card, RTL8169 was not supported by EL 4. This problem was easily resolved. Realtek already have the driver, so all I had to do was install the driver.
Be sure to select gnome windows interface and development tools. System tools may be usefull too.
After EL 4 installed, you will be asked to connect to Unbreakable Linux Network (ULN) to be able to get updates. Well that would be $99 a year.
Lineox.net provide a free update, but with 30 days delays. That is OK for me, this is just for testing purpose. The problem is how to switch update from ULN to Lineox.
First configure the up2date with ULN to make sure up2date can connect to internet. If proxy is used, there are some settings to be defined. Just enter anything on ULN page (user, password, CSI). If the message is CSI not valid, then the connection is OK.
Now update the file /etc/sysconfig/rhn/sources. Comment up2date defaults (add # in the front), and add this line in the end of the file:
### Lineox Enterprise Linux 4.x channels
yum lel4-Updates http://www.raimokoski.com/pub/lineox/4.0/updates/$basearch/RPMS
You may have to restart the machine. After that, up2date will not connect to ULN anymore.
You can also use this mirror:
### Lineox Enterprise Linux 4.x channels
yum lel4 http://www.gtlib.gatech.edu/pub/lineox/4.0/$basearch/os/Lineox/RPMS/
yum lel4-Updates http://www.gtlib.gatech.edu/pub/lineox/4.0/updates/$basearch/RPMS/
