Gateway connection not distributed between application server

Hello,

We have BW system with ABAP and JAVA.stack.

ABAP :  -> with 2 application server

JAVA :  -> with 2 application server

Java system have 2 application server with each have 4 server

nodes.Total - 8 server node

Out of 8 server node, in Visual admin 4 server node jco connection

gateway points to one ABAP application server and another 4 server

node points to another application server.

to avoid the gateway connection traffic to single ABAP application

server, gateway distributed across app. servers

In Java system, visual admin -> Jco connection -> BI Portal jco

connection (ABAP - JAVA Integration) .

But when ever system re-started. setting maintained in Visual admin ->

Jco connection vanished and all server node point to PAS (not

distributed).

Could you give us the location where we can maintain these settings

permanently and remain same even after the re-start.

Thanks and Regards,

Anand
