2 impact servers are in production cluster need to add 2 additional nodes on the same cluster what is the preferred and best way to configure.
To configure the impact cluster server with more than 3 nodes please follow the below steps .
impact.server.preferredprimary=true in the $IMPACT_HOME/etc/_server.props on the primary preferred server.
impact.server.secondary.preferredprimary=true in the $IMPACT_HOME/etc/_server.props on the secondary preferred server.
And please notice, "Start the primary server first, then the secondary server second, followed by the next, and subsequent Impact Servers in the cluster. You can also start the secondary server first, and then the primary server second. The primary and secondary servers that are defined in the ImpactDB data source must always be the first two Impact Servers to start.
Apache Derby supports only a pair of Derby databases for replication."
