OSB not communicating with database using scan-listener


After recently updated datasources to connect to Database using scan-listener instead of service conncetion.

from:
jdbc:oracle:thin:@//<origialAdress>:1521/<INSTANCENAME>

to:
jdbc:oracle:thin:@//<newAdress>:1521/<INSTANCENAME>


Checking database's listener log we can still see some connections coming from osb managed servers.
Not as often as before, but we would like all connection to go through scan-listener

For example we can see following record in listener.log:

/u01/app/oracle/diag/tnslsnr/<origialAdress>/listener/trace/listener.log
---
05-AUG-2021 20:32:41 * (CONNECT_DATA=(CID=(PROGRAM=JDBC Thin Client)(HOST=__jdbc__)(USER=<USR>))(SERVICE_NAME=<INSTANCENAME>)(SERVER=dedicated)(INSTANCE_NAME=<INSTANCENAME>2)) * (ADDRESS=(PROTOCOL=tcp)(HOST=<IPADDRESS>)(PORT=42569)) * establish * <INSTANCENAME> * 0

Host <IPADDRESS> is an application server <SERVER> where osb_server1 is running.
Using netstat on <IPADDRESS> we can see a connection corresponds to pid '6788' which is osb_server1

Can you please help us find what else needs to be updated on OSB side, so that all connections are going through scan-listener and not database-listener?
