Hi Gayathri,
1) You need to select
SAP NetWeaver 7.0 Support Release 3 ------->Software life-cycle options-------->System Copy-------->Oracle--------->SourceSystem Export ------->High Availability System ---->Based on AS Abap and AS Java --------> Database instance export
2) As you do not have HA setup in target system you need to select
SAP NetWeaver 7.0 Support Release 3 ------->Software life-cycle options-------->System Copy-------->Oracle--------->Target System Installation ----->Central System ---->Based on AS ABAP and AS JAVA ----->Central Instance.
3) In case you need additional application server, you can install is using
SAP NetWeaver 7.0 Support Release 3 ------->Software life-cycle options---->Application Server ----Oracle---Dialog Instance
Hope this helps.
