Have recently upgraded database from 10.2 to 11.2. I have a database with two propagations and a single capture. One of the two receiver databases became temporarily unavailable and I see now that there is a capture process and a propagation process that have the prefix "CLONED$_" on them. I have read that the DBMS_STREAMS_ADM.MERGE function will merge these two back into the single but I have never done it. Any thoughts from someone who has experienced it and run the merge?
