Please help newbie...I have changed protections, modified path and am still getting an error when trying to perform an export.

[oracle@massrv lib]$ exp ****/***** file=tst.dmp owner=outage2 indexes=y
exp: error in loading shared libraries: libclntsh.so.8.0: cannot open shared object file: No such file or directory

The file is on the system in the lib directory:

lrwxrwxrwx 1 oracle dba 16 Feb 22 2000 libclntsh.so -> libclntsh.so.8.0
-rwxrwxrwx 1 oracle dba 5800677 Feb 22 2000 libclntsh.so.8.0
