Error when trying to create a Cluster (Active/Active)

Hello all,

I’m running a PoC for future usage of UM in a clustered environment, with version 10.0 TRIAL

When creating a Cluster, through UM EM, I always receive the below error message in the image attached:
“Request not supported on Server”

And also in EnterpriseManager wrapper log:
com.pcbsys.nirvana.client.nSecurityException: Request not supported on Server
at com.pcbsys.nirvana.nAdmin.nAdminSession.createCluster(
at com.pcbsys.nirvana.nAdminAPI.nClusterNode.create(
at com.pcbsys.nirvana.nAdminAPI.nClusterNode.create(
at com.pcbsys.nirvana.nAdminAPI.nClusterNode.create(
at com.pcbsys.nirvana.nAdminTool.gui.actionListeners.nClusterCreate$

In addition I can see the error in the UM log related with server being bound (screenshot attached)
nServerEventHanlder: Error: umserver10 is already bound

The setup is composed of 3 realms. I’ve tried this approach in both these 2 scenarios:

  • 2 remote, separated, Unix boxes (box1 - 2 realms; box2 - 1 realm)
  • local setup in Windows with all 3 realms on the same machine.

Instances were created using the nInstanceManager with option “ALL” for and different ports for each instance.

I’m also in doubt of a statement on the clustering guide, where we can read:
“3. Verify that the permissions on the server machines allow connections to the other servers in the cluster.”
Can someone clarify what permissions are these? OS, Network, UniversalMessaging?

Thanks for any help.
Best regards,

Ok I found this on the nirvana.log file:

[Wed Jul 26 12:18:13 BST 2017] Feature Clustering not licensed and will be disabled

Apparently the TRIAL license does not allow Clustering…
Is there another way to test this functionality?
