Realm offline

I have 3 realms on different servers.

then created a cluster one was assigned as master but the other two realm’s state are offline.

I want the other 2 realms to be slaves for the Active/Active approach.

Is there anything I need to set manually? I followed every step in 10-1_Universal_Messaging_Clustering_Guide.pdf

Need help how to change their state to slaves.

Thanks

Please check if all UM nodes are up or not. Try to connect all three node first in EM.

If all are up and still you are not able to join them in cluster, pls check UM log for any error.

Thanks,
