Hello
setenv LD_LIBRARY_PATH=/usr/sap/AZQ/SYS/exe/run:/usr/sap/AZQ/SYS/exe/uc/sun_64:/oracle/client/11x_64/instantclient
export LD_LIBRARY_PATH=/usr/sap/AZQ/SYS/exe/run:/usr/sap/AZQ/SYS/exe/uc/sun_64:/oracle/client/11x_64/instantclient
This will only last until you end the session. To set the environment variables permanently you need to set them in the respective environment variable files for the user.
There must be already 10G Oracle Instant Client present with the environment variables pointing to it.
You need to adapt the files to point it to 11G Oracle Instant Client location.
Provide the output of this command
su - sidadm
grep client .*
Regards
