Installing OracleClient11g on UbuntuServer

It's did by this instruction: http://www.gena01.com/forum/gena01-blog/oracle-instant-client-11g-on-ubuntu/

I did follow:

1. Installling libaio1 (must for Oracle 11g, optional for 10):

apt-get install libaio1

2. Installing alien:
apt-get install alien

3. Downloading RPMs from here:
http://www.oracle.com/technetwork/topics/linuxsoft-082809.html

4. RPMs converting into .deb through alien:

alien [download_file.rpm]

5. Installing debian-package:

dpkg -i [file_from_paragraph_4.deb]

6. And finally, doing this command:

aptitude search oracle

And we must see:
