Hi SS,
Thanks for guiding.
Steps taken:
1. Started installation again with Oracle RDBMS package 10g and client 10.2.
2. During import ABAP phase , where R3load requires oracle client 11 , created softlink for libclntsh.so.11.1 to libclntsh.so.10.1
3. Installation finished without any further big issues, few permission issues came.
Regards,
Ashraf
