We installed OBIEE11g new linux box(server2).In that box 11g client version installed already.
We able to connect (ping) oracle when login linux box .
We migrate 10g into (server2)11g catalog and RPD.After we cant able to open online mode.But not able to View data in physical layer.
It return error " The Connection Has Failed"
