Hello,

lets have two  abstract %Persistent classes A,B with NoExtent keyword (storing data in separate globals for each subclass).

Class A Extends %Persistent [Abstract, NoExtent]

{

}

Class B Extends %Persistent [Abstract, NoExtent]

{

     Property Aref As A;

}

Let B class reference the A class. Since the A class has no extent the reference wont work in subclasses. It wont be even usable in SQL.  Is it possible to solve this problem? Whats the recommended way to deal with references/relationships using NoExtent?

Hello everyone,

i want an automatic unidirectional syncronization of multiple databases (some tables from .dat file, not the whole .dat file) . 

So far i have tried everything from package %SYNC and the best working class is SyncSet with journals and guids. The problem is initial database transport for example when i want to add another server.  The easiest solution i have found is to transport syncing globals ^OBJ.SYNC.N to another database and then call %SYNC.SyncSet.Import(), however it seems not to work with only the global structure, although it works fine using import files.
