Hi All, I have a 4 node test setup. It is very simple, with one set, containing one table. The origin is node 1. The view of sl_listen is as below. All nodes listen for events directly from the origin node of an event. (i.e. provider of events from node 3 is always node 3). Great so far.. li_origin | li_provider | li_receiver -----------+-------------+------------- 1 | 1 | 2 1 | 1 | 3 1 | 1 | 4 2 | 2 | 1 2 | 2 | 3 2 | 2 | 4 3 | 3 | 1 3 | 3 | 2 3 | 3 | 4 4 | 4 | 1 4 | 4 | 2 4 | 4 | 3 After issuing a move set from node 1 to node 2 (which was successful) the listen table now looks like this: li_origin | li_provider | li_receiver -----------+-------------+------------- 1 | 1 | 2 1 | 1 | 3 1 | 1 | 4 2 | 2 | 1 2 | 1 | 3 2 | 1 | 4 3 | 3 | 1 3 | 3 | 2 3 | 3 | 4 4 | 4 | 1 4 | 4 | 2 4 | 4 | 3 All db changes now happen in node 2, but instead of listening to node 2 directly, nodes 3 and 4 are getting the changes via provider node 1. This is not what I had expected, as presumeably the point of moving set is quite often to then take down the old origin. Anyway, I thought no worries, I'll just send a couple of store path commands to get nodes 3 and 4 listening to node 2 directly. I did this using <slon preamble> store listen (origin=2, provider=2, receiver=3); store listen (origin=2, provider=2, receiver=4); This seemed to have no effect at all and I can't see any evidence of the store listen commands being processed. Is what I am doing correct? Is it possible to now get nodes 3 and 4 listening directly to node 2, so I can drop node 1 from the replication completely?
