Hi Pipo,

I turned on the tracing. But i don't see the duplication of ADDRESS. But still 12564. Then i removed tnsnames.ora on client. Configured again. But no luck !!

Let me know if u want to see the trace file.

FYI : Just want to check if there is anything wrong in my configuration.

DB Instace running on Machine A:1521
CMCTL running on Machine B:1630
Client Machine C

> C has got sqlnet.ora which has USE_CMAN = true & NAMES.DIRECTORY_PATH= (TNSNAMES). And tnsnames ora with SOURCE_ROUTE = TRUE and address pointing to machine B:1630

> Machine B has got cman.ora pointing Source as machine C & Dest machine A and instance as of Machine A


Let me know if i am wrong somewhere .

Thanks & regards
