MAPSET_INCOMPATIBLE_PLACEMENT_STRATEGY_CWOBJ4918=CWOBJ4918E: Domain {0} is not going to send updates to domain {1} for map set {2} from ObjectGrid {3} because the placement strategy on foreign domain {1} is set to something other than a FIXED_PARTITION strategy.
Explanation
The map set must be configured to use a fixed partition placement strategy in order to achieve a multi-primary topology.
User response
Stop the containers that host the map set in 1 of the domains. Restart these containers with a fixed partition placement strategy.
