unable to start DBCA

I am unable to invoke dbca. We are running 9.2.0.3.(Linux x86-64 ,RH-4) The error I get is class not found: oracle.sysman.assistants.dbca.DBCA

Here are the contents of oracle user's .bash_profile:

cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/sbin
export PATH

ARC_HOME=/opt/CYEora8
export ARC_HOME
LD_LIBRARY_PATH=/u01/app/oracle/product/9.2.0/lib:$ARC_HOME
export LD_LIBRARY_PATH
unset USERNAME
alias rm='rm -i'
alias lt='ls -lt'


Attached below is $PATH output:


echo $PATH
/u01/app/oracle/product/9.2.0/bin:/usr/ccs/bin:/usr/openwin/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/u01/oracle/bin:/u01/app/oracle/admin/scripts/bin:/u01/app/oracle/admin/scripts/lib:/u01/app/oracle/admin/scripts/sql:/u01/app/oracle/admin/scripts/tmp:/u01/app/oracle/admin/patch/OPatch:/u01/oracle/bin:/sbin

If I remember right, I think you need to run "linux32 bash" first

where is your ORACLE_HOME?
