NetWeaver XI components are not talking to each other

I am an XI consultant, i dont have proper Basis support at my client, since they are fond of only ABAP stack.

They installed netweaver xi from the market place.

I am unable to import any SWCV (even SAP BASIS) from SLD to IR and IR menu is blank.

Unable to find list of adapters in Integration Directory.

RWB -component monitoring is blank .

SLD- creation of products,SWCV,Technical Sys,Buss Sys is possible.

In conclusion i can say that they all are not co-operative and not talking to each other

And also i want to know wheather xi 7.0 is compatable to databases Oracle 8.0.3 and Oracle 8.0.4
