Installing OAS when Oracle database alreay installed

Question

I am installing Oracle App Server . The installation document says to unset my ORACLE_HOME and ORACLE_SID variables. If i does so, my ORACLE database will stop working.
How can i run both App Server and database on same Node. Is there any workaround for that.

Is this Windows or Linux/Unix?
I would recommend installing everything with the same user, for instance ORACLE. For each installation you have, you have to have different profile-environment-shell-files.
For instance:
db.sh - to set database environment
infra.sh - to set infrastructure environment
midtier.sh - to set middle-tier environment
This is an example environment file for a Portal (middle-tier environment):
# Portal (Middle-tier) Environment
# By Martin Malmstrom, ORACLE Consulting
export ORACLE_HOME=/u01/app/oracle/product/midtier
export OH=$ORACLE_HOME
export PATH=$OH/bin:$OH/opmn/bin:$OH/dcm/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin
alias oid=". ~/oid.env"
alias sso=". ~/sso.env"
alias portal=". ~/portal.env"
alias soa=". ~/soa.env"
echo Portal environment setNote that with the alias I create, I can quickly change between the environments, which wouldn't be possible if I'd installed everything with different users.
Set the environment with: $ . ./portal.env (note the two dots). When one environment is set, one can switch with just the alias, for instance: $ oid (to set the OID environment)
