Question concerning run rules
Hi Craig,
the run rules state, that the .orm files must not be changed by JDO
vendors.
The ORM for datastore identity specifies strategy "identity". Can a JDO
implementation, which only supports datastore identity and which only
runs on a RDBMS that has sequences and no identity columns, successfully
pass the TCK without changing the ORM?
Would it make sense to allow such vendors to change the ORM for
datastore identity in order to specify strategy "sequence"?
Regards,
Michael

I'd second the motion that the TCK ORM should use native instead of
identity. It's the default, so we can just remove the strategy entirely.

Hi Michael,
would it make sense if the TCK ORM files for datastore identity use the
strategy "native" instead of "identity"?
