Subject Firebird database seems to influence multi user ability
Author Benny Schaich-Lebek

I have been an interbase guy about fifteen years ago and loved to see it go open source. I used to work with Paul Beach (Hello, if you're here,Paul)

Now I ran across a problem with firebird and tried to solve it. unfortunately half of the stuff is in the dark because the original software running here is an accounting product (BUHL/Deltra office Software/Germany if you have heard about it).

The weird thing is that the software does not connect to the server from a client if there is a specific .fdb file loaded (local access works). I now asked them to run a backup and that had a couple of messages:
 (gbak:cannot commit index MOV_CALITEMS_ORDERID
gbak: ERROR:violation of FOREIGN KEY constraint "MOV_CALITEMS_ORDERID" on table "MOV_CALENDARITEMS"
gbak: ERROR:    Foreign key reference target does not exist
gbak: ERROR:    Problematic key value is ("ORDERID" = 4127)
gbak:Database is not online due to failure to activate one or more indices.
gbak:Run gfix -online to bring database online without active indices.)

Specifically the last one makes me suspicious. How come that local access works then? I thought even local access always goes through the server?

Any hints anybody? I know this is hard to determine as we do not know much about the program itself, but it seems the guys from the software shop have trouble to understand firebird...
