Installing Fedora Core 8 on Linux or Brainfucking part 1

There appeared a need to install Oracle Database 10g several days ago. All i had was Fedora Core 8 with a command line interface.
As a decent person I started with http://www.oracle.com/technology/pub/articles/smiley_10gdb_install.html. But it turned out this manual is not enough because FC is not supported by Oracle.
Also I read from oracle forums that installing Oracle DB on FC8 "is a real pain". Although I decided not to give up, but to try to get the target.
Firstly, I followed the intructions from http://www.oracle-base.com/articles/11g/OracleDB11gR1InstallationOnFedora7.php:
1) Unzipped "linux_11gR1_database.zip"
2) Changed kernel parameters:
a) created a file "/etc/sysctl.conf":

 kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=262144

b)executed "/sbin/sysctl -p" to apply changes immediately

3)added the following lines to the /etc/security/limits.conf file:
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  1024
oracle              hard    nofile  65536

4) added the following line to the /etc/pam.d/login file:

session    required     /lib/security/pam_limits.so
session    required     pam_limits.so

5) disabled secure linux by editing the /etc/selinux/config file:
SELINUX=disabled

6) installed the following packages:
rpm -Uvh binutils-2.*
rpm -Uvh elfutils-libelf-0.*
rpm -Uvh glibc-2.*
rpm -Uvh glibc-common-2.*
rpm -Uvh libgcc-4.*
rpm -Uvh libstdc++-4.*
rpm -Uvh make-3.*
rpm -Uvh elfutils-libelf-devel-0.*
rpm -Uvh glibc-devel-2.*
rpm -Uvh gcc-4.*
rpm -Uvh gcc-c++-4.*
rpm -Uvh libstdc++-devel-4.*
rpm -Uvh unixODBC-2.*

yum install libaio libaio-devel
yum install unixODBC-devel
yum install sysstat

7) created necessary users and groups:
groupadd oinstall
groupadd dba
useradd -g oinstall -G dba,oracle
passwd oracle

8) created the directories in which the Oracle software will be installed:
mkdir -p /hdd1/oracle/product/11.1.0/db_1
chown -R oracle:oinstall /hdd1
chmod -R 775 /hdd1


9) edited the /etc/redhat-release file replacing the current release information (Fedora release 8 (Werewolf)) with the following:
redhat release 5

10) logged in as the oracle user and added the following lines at the end of the .bash_profile file:
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=HIDServer; export ORACLE_HOSTNAME
ORACLE_BASE=/hdd1/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/10.2.0.1/db_1; export ORACLE_HOME
ORACLE_SID=O10GSID; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

Now according to that tutorial oracle should be installed successfully, but new troubles appeared as it turned out.

Trouble #1: Runnning ./runInstaller, I got such exception:

Preparing to launch Oracle Universal Installer from
/tmp/OraInstall2005-08-30_10-54-49PM. Please wait
...[oracle@localdomain database]$ Exception in thread "main"

Having spent some browsing forums I got the solution - all you need to install libXp:
yum install libXp

Retrying to run installer I got:
Trouble #2: I got the error message something like 'Unable to open display'.
Browsing forums again (forums rule the world :)), I read that X Windows System is needed to be installed, so I did it: X-Server + GUI Gnome
But! There is one small thing - you need to switch to "runlevel 5". You can do this by "telinit 5" [or: "init 3"]

Ok, I got the GUI interface - tried to run damned installer again.
WTF?! This time error message was more informative:
 xcb_xlib.c:50: xcb_xlib_unlock: Assertion 'c->xlib.lock' failed.

gtg - to be continued :)
