I have been using AGS for many years in conjunction with SDE data. As such I have found that SDE feature classes in mapservices put a lock on the SDE data when the mapservice is running.
Recently, my organization created a query layer from a SDE feature class and a table. When performing maintenance on the domains for the SDE feature class all locks needed to be cleared. All mapservices hitting the SDE feature class were stopped, but not a mapservice hitting the query layer, so I thought there would be 1 lock left, but there were none.
So my question is do Query Layers in SDE no longer generate lock files in mapservices like feature classes from SDE would?
Any help or hints on this topic are greatly appreciated.
