Decision Service calls failing with connection refused

Question

Hi All,
Breifing of the bpel process - Async bpel process XX_BPEL_ASYNC_002 calls decision services and a sync bpel process XX_BPEL_SYNC_001.
We have moved to cluster 10.1.3.5.0 from 10.1.3.3.0 and the deployement of the bpel process and the decision service done on two nodes i.e., node51 and node55.
But the bpel process is able to call the decision service only when the node 51 is UP and running, but if node 51 is down and node 55 is up and running it is failing with connection refused error. It is also working when 55 is DOWN and 051 is UP.
the exact error is:
exception on JaxRpc invoke: HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Message send failed: Connection refused.
We are using file based repository.
It is failing when it tries to call particular url:
http://loadbalancerurl:7777/orabpel/domain001/XX_BPEL_ASYNC_002/1.0/decisionservices.decs
Can anyone please help me or advice me for finding some solution.
Thanks

Hi Fatsah,
It has been a while since we resolved this problem. But these were  the basic steps that we had taken.
The receiver was configured a File adatpter with FTP:
Port: 10021
Connection security : FTPS (FTP using SSL/TLS) for Control and Data Connection
Command Order: AUTH TLS,USER,PASS,PBSZ,PROT
Problem: The message was blocked in our firewall.
FTPS in this case used 10021 as the control port and the firewall allowed to pass the control request.
Once the connection was accepted at the control level, it generated a random port number  to pass data on the channel.
This random port number was blocked in the firewall.
We monitored the data port numbers generated at firewall. Then we configured the firewall to open any port number  between the specific IP addresses of the sender and the receiver. That resolved the problem.
Hope this helps!
Please give points if this is helpful.
Thank you.
