Hi Obnoxio The Clown, My client is upgrading the whole enviroment (OS, DB, application and hardware), they will use SAP R/3 with 3 applications servers in a subnet and other 3 apllications servers in a different subnet. So, every application have to "see" the same dbservername, otherwise this applications servers (R3) won't start. Thanks for your attention !! and if you have other idea will be great.

There is a slight performance disadvantage (most likely not noticeable) compared to having multiple listeners defined using DBSERVERALIASES. Both ways are covered in the Admin Guide. Hope this helps, Heiko

On the server you would have the sqlhosts file as you show it above but on a server on the second subnet have the following entries: online_tcp1 onsoctcp hostname2 service2 online_tcp2 onsoctcp hostname1 service1 You see the engine will be listening on hostname1 for connections using service1 and on hostname2 using service2 but will NOT CHECK the server name against the sqlhosts entries ONLY against DBSERVERNAME and the list of DBSERVERALIASES! This will work like a charm, do it all the time. -- Art S. Kagel & Family kagel@erols.com
