Cluster on WebSphere

[anatoleus]

I am wondering if anyone has come across a similar issue:

I have two AIX boxes with WebSphere6.1 running on them. I would like
the application deployed to WebSpheres to be clustered via Hazelcast
1.8.5. Both boxes can "see" each other via ping. The multicast is
enabled on both and even a simple Hazelcast tester works perfectly
when kicked off as a standalone java app on each box. The cluster is
being formed. However, when deployed within WebSphere it starts two
separate clusters, one on each box. Same code/EAR/Hazelcast/WebSphere
on two different Win boxes, again form a perfect cluster.

So it seems neither the code nor the network/sys configuration are
responsible for the problem. I gotta be missing something obvious
here...

any recommendations would be appreciated.
Thanks!

I've had problems sometimes when I launched two nodes simultaneously.
Have you tried to deploy one and wait maybe 30 seconds before
deploying the other?

Thank you, Adrian.

My issue seems to be related to the WebSphere configuration. Although,
running a Java test on the same box using the same JDK does not
require IPstack preference to be defined, under WebSphere I had to
explicitly set java.net.preferIPv4Stack=true. After that it works as
expected.
