[MonoDevelop] Mono 3.6.0 Exception: libclntsh.so at (wrapper managed-to-native) System.Data.OracleClient.Oci.OciCalls/OciNativeCalls:OCIEnvCreate

[Hari]

I have resolved the issue by creating a  sysmbolic to the file :
*libclntsh.so*

ln -s /opt/instantclient_11_2/libclntsh.so.11.1
'/usr/local/lib/mono/gac/System.Data.OracleClient/2.0.0.0__b77a5c561934e089/libclntsh.so

Thanks
