hmmm ... you definately got a lot of stuff in there ... maybe your paths are not set properly? Where is your .profile file located?

mine looks like this in C Shell:

umask 022
setenv ORACLE_BASE /u01/app/oracle
setenv ORACLE_HOME $ORACLE_BASE/product/8.0.6
setenv ORACLE_SID AP01
setenv ORACLE_TERM xsun5
setenv LD_LIBRARY_PATH $ORACLE_HOME/lib
setenv DBA /export/home/oracle/dba
setenv TOOLS /export/home/oracle/tools
setenv BACKUP_HOME /u04/oradata/AP01/exports
setenv PATH /usr/ccs/bin:${PATH}:$ORACLE_HOME/bin:/opt/oracle/bin:${TOOLS}:${DBA}:${BACKUP_HOME}
cd $ORACLE_HOME
