To set system scaling parameters when you create a software event broker instance, you can use configuration keys. For example, with Docker Engine, you can use the docker create command. Adding the line below to the docker create command sets the maximum client connections to 200,000.
--env 'system_scaling_maxconnectioncount=200000'
For more information, see Initializing a Software Event Broker Container. For more information about the configuration keys that are available, see Configuration Keys.
To increase system scaling parameters for software event brokers that are running, see Scaling Up an Existing Single Software Event Broker and Scaling Up an Existing HA Group
