Hi, I am facing some problem with merging two zodb file. is it possible to open two zodb Database at a time and copy object from one to another.

Yes, using the export/import mechanism.

Another option is to mount both ZODB's and then copy the objects. It is necessary to decouple the copy from its source before it can be stored in the target. Apparently, "copy.deepcopy" is able to reliably decouple. -- Dieter
