ODMG implementation currently does not support nested tx, but you can use tx.join() to do something like tx1.begin() ... tx2.begin() // do something tx2.commit // tx2.abort() ... tx1.join() tx1.commit() // tx1.abort() regards, Armin > > Intended useage: > > 1. open odmg-transaction > 2. make an independent read-update-write by PB (transaction will be done > in one go) > 3. use odmg-transaction > 4. make a second independetn read-update-write by BP > 5. commit odmg-transaction > > an example would be nice > > joerg > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
