@Michael,

Have you created a database successfully before trying to start it up or connect to it with sqlplus? DBCA will not be able to create the database without libaio.

Cheers!

dbca trouble. After successfully installed Oracle 11g, I went ahead to create the first database using dbca. however at the last step, it complains that libaio is not installed, and it can not execute the sqlplus. I did install the libaio1 however, and as a matter of fact, I can run sqlplus at terminal. So what could be the problem?

Thanks for the detailed help! To install ORACLE on your own machine, you just follow the steps in this article except that you log out after you created the user oracle. Then login in as the user “oracle” and pick the rest steps. Other things I tried and didn’t work is to play with 127.0.0.1, localhost or :0, xhost and so on.

Dear there, I followed your steps, and stuck at DISPLAY Setting. I am setting up 11g on my T60p running Ubuntu 8.04 - the Hardy Heron. Since I don’t connect to any server, I set the DISPLAY=:0.0 However it didn’t work out. Please give me a hint, thanks.

it is strange that as a common user “sychen” I can run xclock directly even without DISPLAY variable; as the root , I run the xclock and can see the clock, but got the warning msg; as “oracle”, I can not connect to xserver.

@Coren, Executing chmod -R o+rwx won't do any good as what's important in this stage is the user and group. Please make sure you selected the proper values here. Cheers!

I tried executing the command “chmod -R o+rwx oraInventory” from root and then start OUI but the problem persists. I’m not sure I understand the part about the location of the inventory directory or the “right after firing OUI”.

Thanks again

@coren,

Please double check the location and permissions of the inventory directory you’re trying to use (right after you fire up OUI).

Cheers!

Thanks. With this tutorial the installation went smoothly.

When installation completed I realized I want to add Enterprise Manager Database Control however when I run OUI and click the “Installed Products” button the Inventory window opens but remains empty (the list of installed products does not appear, instead I see an empty inventory window).
Is this a known bug for Oracle on Ubuntu? Is there a workaround to add\remove products from the Oracle inventory?
