To apply data captured from multiple source containers or catalogs to a target Oracle container database, both three- and two-part names are required. In the MAP portion of the MAP statement, each source object must be associated with a container or catalog, just as it was in the TABLE statement. This enables you (and Replicat) to properly map data from multiple source containers or catalogs to the appropriate target objects. In the TARGET portion of the MAP statement, however, only two-part names are required. This is because Replicat can connect to only one target container or catalog at a time, and schema.owner is a sufficient qualifier. Multiple Replicat groups are required to support multiple target containers or catalogs. Specify the target container or catalog with the TARGETDB parameter.
