I've noticed a handful domains are listed twice in GDB_ITEMS. Is that normal? The records are identical except for the UUID column.
Coincidentally, I'm having trouble modifying one of these domains in ArcCatalog. There is not an error or warning but the changes do not save. Thanks!
This could be the result of the domain having two different "owners". If you compare the XML documentation column of the GDB_ITEMS table do you see the fully qualified name of the domain having a different owner?
