To manually scale in or out of a FEPCluster, edit the "spec.fep.instances" in FEPClusterCR.
The value must be between 1 and 16. (Number of instances with one master)
$ oc edit fepcluster <FEPClusterCR name>
Note
Do not scale in from two to one replica instance when the syncMode is 'on'. Update SQL cannot be executed.
Any database connections to the replica Pod that are deleted during a scale in will be forced to disconnect.
