SAP Installation Error

hi experts,

I am trying to install SAP Netweaver 7.31 system. During installtion i got erros as follows...

And when i see log at the location /~/STD/ABAP then below is the log details..

/oracle/<SID>/112_64/bin/lsnrctl: error while loading shared libraries: libclntsh.so.11.1: cannot open shared object file: No such file or directory.

I found SAP note no 819829 where mentioned that if u got above mentioned error then check environment varible "LD_LIBRARY_PATH".

I checked that variable, and its fine.

Please comment and suggest solution for this....

Regards,

Suhas.
