sql server replication:
I am confused about how to interpret the Merge Agent History panel and the Session Details of the Merge Agent panel. The Merge Agent History panel has columns to the right that indicate pretty clearly where the action is occuring, at the Publisher and at the Subscriber. In my case I see lots of inserts at the Publisher. Next when I open the Session Details of the Merge Agent panel, I see a set of actions all indicated as downloads. If the details panel is from the perspective of the subscriber, then this would contradict the parent History panel. It is only consistent if the Detail panel is from the perspective of the Publisher. Then 'downloads' would correspond to inserts and such at the Publisher. So my question is, "Is the Detail panel showing uploads and downloads from the perspective of the Publisher or the Subscriber?" Thanks in advance for clarifying this. Jeff Roughgarden, MCSD, MCDBA
Paul, If that is the case, then the two displays I see are contradictory. Do you also see this contradiction? Jeff
Paul, I emailed you screen shots of the apparently contradictory History and Detail panels. Jeff
Jeff, I must be missing something :). AFAIK download always means publisher to subscriber, while upload means subscriber to publisher. On my merge agent the figures I see for subscriber inserts and publisher inserts are consistent with this. Perhaps you could post up a screen shot of a state which is inconsistant, or is the question more on a symantic nature ie should download always mean publisher to subscriber?

Jeff, please could you send to paul.ibison@replication answers.com (no space). Cheers, Paul Ibson
Jeff, surely we must be talking at cross-purposes :) An insert at the publisher is downloaded and inserted at the subscriber - why is this contradictory? Cheers, Paul Ibison
I really do apologize for seeming so dense, but they still seem contradictory to me. Referring to my original message, the Merge Agent History panel shows clearly 50925 'Inserts at Publisher'. However clicking on the Session Details button, the resulting panel shows a long list of ***download*** actions (inserts) whose record sum presumably equals 50925. This is contradictory. How can we have 50925 inserts at publisher and 50925 downloads leading to inserts at the subscriber? Jeff
(I received Jeffs pictures sent directly to me but they are too large to post here) Jeff, these pannels seem entirely consistent to me:) The number of publisher changes is consistent between the pannels. The term 'download' is used to describe a publisher -> subscriber change. The total also matches the sum of the individual batch totals. Cheers, Paul
