To start the Server, you need to give it the location of the schema.

You can copy the CLI commands to start the replication server form coherence Hub > Servers tab.

You can also define other parameters like min-query-distance (the minimum distance the LiveQuery needs to move for the Replicator to recognize a change), send and receive frequency, ip and port number.

Minimal parameters set is presented in the example below:

replication-server serve --port 32001 --signalling-port 32002 --send-frequency 20 --recv-frequency 60 --web-support --env dev --schema "/Users/coherence/unity/Coherence.Toolkit/Toolkit.schema,/Users/coherence/MyProject/Library/coherence/Gathered.schema"
