I'm using an Oracle 11g backend, have my sequences all set (with
caching
set to 0 in cayenne modeler), and it works fine until my program
throws an
exception. Now this exception is being thrown after I'm calling
commitChanges() on the dataContext, but the next time I run my
application
it complains about a PK violation and I need to wipe my test DB before
going forward. any ideas?
So are you trying to re-commit the same "dirty" objects again after an
exception? Not sure if the Oracle sequences are transactional and are
subject to rollback, but if they are, I guess the assigned PK values
are no longer valid. We may need to test this scenario in Cayenne
(Jira anyone?) and maybe reset the generated object PKs on rollback.
In the meantime, you can rollback your ObjectContext on exception and
start with fresh objects.

I'm storing zipped file content in BLOBs... it seemed to be working
fine
yesterday, but now I get this (the files today might just be larger,
these
files might get pretty big ~1.5GB)....

Check max length for this column in Modeler. It looks like this is
coming from that setting.
