Create database in RAC 10g

Question

Hi everyone,
I have problem with create database on Oracle 10g RAC (RedHat Enterprise Linux 5.5 64bit). When I install OCR so everything ok... ocr running.. if I want create database using dbca and select RAC then show me message when informed me about needed upgrade OCR... so I install patch 10.2.0.4 (installation was ok - without error) and I try create db again... The problem is the same. If I want select option singl instance so everything is ok.
Can you help me?

Fahd Mirza,
everything install over oracle user...
I have two groups (oinstall and dba) and user oracle....
this is profile for oracle user:
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
export ORACLE_BASE=/u01/app/oracle
export CVUQDISK_GRP=oinstall
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORA_CRS_HOME=$ORACLE_HOME/product/10.2.0/crs_1
export PATH=.:${PATH}:$HOME/bin:$ORACLE_HOME/bin
export PATH=${PATH}:$ORA_CRS_HOME/bin
export PATH=${PATH}:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin:/sbin
export ORACLE_ADMIN=$ORACLE_BASE/admin
export TNS_ADMIN=$ORACLE_HOME/network/admin
export LD_LIBRARY=$ORACLE_HOME/lib
export LD_LIBRARY=${LD_LIBRARY}:/lib:/usr/lib:/usr/local/bin
export LD_LIBRARY=${LD_LIBRARY}:$ORA_CRS_HOME/lib
export CLASSPATH=$ORACLE_HOME/JRE

export CLASSPATH=${CLASSPATH}:$ORACLE_HOME/network/jlib
export THREADS_FLAG=native
export ORACLE_SID=VIDEOBET
PATH=$PATH:$HOME/bin
directory permission:
drwxr-xr-x 45 root oinstall 4096 Jun 14 05:20 crs_1
