Setting environment using custom script

Question

In our environment we have multiple db's of different versions running on same server.
We are building a custom env script to set all env variables. We have created below script, it's not setting environment.
Script is :
#!/bin/sh
set -x
if [ $# != 1 ] ; then
echo "Wrong number of parameters.Expected Oracle sid as parameter..exiting!!"
exit 1
fi
PATH=/var/opt/oracle/bin:/usr/bin:/usr/xpg4/bin:/usr/ucb:/usr/openwin/bin:/usr/dt/bin:/usr/local/bin:/usr/ccs/bin:/opt/SUNWspro/
bin:/opt/EMCpower/bin:/etc:/var/opt/oracle/standard/bin:/sbin:/usr/5bin:/usr/sbin:/usr/openv/neer/bin:/usr/openv/netbackup/bin:/
usr/proc/bin:/usr/afsws/bin; export PATH
unset ORACLE_SID LD_LIBRARY_PATH LIBPATH ORA_NLS33 ORA_NLS10
ORACLE_SID=$1
export ORACLE_SID
ORAENV_ASK="NO";export ORAENV_ASK
. oraenv
if [ $? != 0 ] ; then
echo "Running oraenv again from standard location /usr/local/bin/oraenv"
. /usr/local/bin/oraenv
fi
echo "Oracle home is $ORACLE_HOME"
LD_LIBRARY_PATH=$ORACLE_HOME/lib; export LD_LIBRARY_PATH
LIBPATH=$ORACLE_HOME/lib; export LIBPATH
SHLIB_PATH=$ORACLE_HOME/lib; export SHLIB_PATH
ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data; export ORA_NLS33
ORA_NLS10=$ORACLE_HOME/nls/data; export ORA_NLS10
If I do env | grep ora after script finishes. Changes in environment variable are not reflected. kindly help. Although I used set -x and saw that it's running fine.

Not sure what you mean, but if I understand your need, functions might be a solution.
The following is my oracle user's profile (it's Linux, but Solaris shouldn't be different) :
export EDITOR=vi
umask 022
export ORACLE_BASE=/home/oracle/base
o10()
{       export ORACLE_SID=db102
        export ORACLE_HOME=$ORACLE_BASE/OraHome10
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib
        export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
        export TNS_ADMIN=$ORACLE_BASE/OraHome11/network/admin
        export PS1='[\u@\h_10 \W]\$ '
o92()
{       export ORACLE_SID=db92
        export ORACLE_HOME=/scsi/OraHome92
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib
        export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
        export TNS_ADMIN=$ORACLE_BASE/OraHome11/network/admin
        export PS1='[\u@\h_92 \W]\$ '
o11()
{       export ORACLE_SID=db11
        export ORACLE_HOME=$ORACLE_BASE/OraHome11
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib
        export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
        export PS1='[\u@\h_11 \W]\$ '
xe()
{       export ORACLE_SID=XE
        export ORACLE_BASE=/usr/lib/oracle/xe/app/oracle
        export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/server
        export LD_LIBRARY_PATH=$ORACLE_HOME/lib
        export PATH=$ORACLE_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
        export TNS_ADMIN=/home/oracle/base/OraHome11/network/admin
        export PS1='[\u@\h_XE \W]\$ '
}If I want to set Oracle 10 environment I enter
$ o10
and similarly for others.
