MAPSET_INCOMPATIBLE_PLACEMENT_STRAT_CWOBJ4901=CWOBJ4901E: Domain {0} will not send updates to domain {1} for map set {2} from ObjectGrid {3} because of a mismatch in the placement strategy. The map set is configured for {4} placement strategy in domain {0} and {5} placement strategy in domain {1}.
Explanation
The map set must be configured with the same placement strategy in each domain in order to achieve a multi-data center topology.
User response
Stop the containers hosting the map set in one of the domains. Restart these containers using a deployment policy containing the map set with the proper placement strategy.
