Oracle Database Discussions

Hi all,
I've installed oracle 10gR2 on Debian_3.1_R4_stable with no problem.
Database XE is started when start the server, but error message appears in file alert_XE.log:

Cannot determine all dependent dynamic libraries for /proc/self/exe
Unable to find dynamic library libocr10.so in search paths
RPATH = /ade/aime1_build2101/oracle/has/lib/:/ade/aime1_build2101/oracle/lib/:/ade/aime1_build2101/oracle/has/lib/:
LD_LIBRARY_PATH is not set!
The default library directories are /lib and /usr/lib
Unable to find dynamic library libocrb10.so in search paths
Unable to find dynamic library libocrutl10.so in search paths
Unable to find dynamic library libocrutl10.so in search path

I have added following line in file /root/.profile
export LD_LIBRARY_PATH=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/lib:/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/ctx/lib

and I happen to restart database every time after loading the server.
Where me to reference to LD_LIBRARY_PATH prompt please.
