Re: OJb sequence manager - Force computation of unique values

Thu, 05 Feb 2004 03:16:37 -0800

Hi again,

oracle does support DB sequence based key generation. Do you specifiy oracle platform in jdbc-connection-descriptor 'platform' attribute?

regards,
Armin

Hi Armin,

once again thanks for the response,
we are you running OJB in an managed environment, we changed the sequence implementation to be : Database sequences based high/low implementation.

we are using oracle 8 as our database.

and we now receive the following error :

Hi,

from your stack trace

Caused by: org.apache.ojb.broker.TransactionNotInProgressException: ConnectionManager is NOT in transaction
at org.apache.ojb.broker.core.PersistenceBrokerImpl.abortTransaction(Unknown Source)

Seems that an internal exception occur while lookup of the next HighLowSequence object and OJB try abort internal used PB instance.
Now, here is my question: Are you running OJB in an managed environment?
If yes, this sequence manager implementation will not work. See
http://db.apache.org/ojb/sequencemanager.html#High/Low sequence manager

By the way, I will update SequenceManagerHighLowImpl to log a clear error message.

regards,
Armin

Hi,

Folks,

we are using the High/Low sequence manager implementation and we try to compute the id in advance with the following code :

PersistenceBroker broker = ((HasBroker) tx).getBroker();
Identity oid = new Identity(object, broker);

we encounter in the following error error :

org.apache.ojb.broker.metadata.ClassNotPersistenceCapableException: Can not init Identity for given object



Say that class of given object could not be found in repository. But maybe there is another reason for that failure, please post the whole stack trace and the error log before failure.

regards,
Armin



what can be the problem?

thanks.
