I am trying to implement Universal Messaging clustering in Master/Slave model. The steps followed are as below .
Two Universal Messaging Servers are installed on different hosts(Here, the hosts are docker containers ).
Created one instance of Realm Server (other than default , after shutting down the default instance).
Used the command as ./ninstancemanager.sh create umserver1 RS 0.0.0.0 9000 and
./ninstancemanager.sh create umserver2 RS 0.0.0.0 9000
Confirmed that there is no directory/folder as /naming/defaultContext in the instances created . (As UM clustering guide states before clustering creation steps & verification)
Next , connected to Enterprise manager & then selected option of connect to Realms.So, one by one both Realms were connected .
Selected cluster creation option . Provided Cluster Name and added the Realms .
Post adding the realms in cluster I can see small ‘c’ tagging on the realm servers connected .
Clicked On cluster name created and then clicked on sites option . Added Primary & secondary sites and then voted Primary for IsPrime .
Now, the problem is in cluster Summary page . The realm servers are showing itself as local but the other as either offline/Disconnected . The screen shots are attached here .
I tried telnet one Um host to another on the docker public port and it was getting connected .
When the messages shown in Cluster summary page is also varying as one realm says other as disconnected and other says as offline ?
Have I missed anything in the cluster set up steps? Could you please validate my steps followed and suggest if any other configurations need to be done.
