Hello
Could you confirm under which user you ran those LDD command against brconnect ?
LD_LIBRARY_PATH=/usr/sap/<SID>/SYS/exe/run:/oracle/client/11x_64
The evnironment variable should be /oracle/client/11x_64/instantclient which is a symbolic link to a directory called instantclient_11203
ls -la /oracle/client/11x_64/instantclient_11203
Change the permission of the files under /oracle/client/11x_64/instantclient_11203 to sidadm:sapsys
Regards
RB
