Collegamenti di database non chiusi dopo il timeout di inattività Origine dati

Question

Ho un'applicazione in esecuzione su wildfly 8.1 Le connessioni di database utilizzate nelle applicazioni sono ricavate da un'origine dati definita nel file standalone.xml.

Problema: non so perché ma la connessione dal pool non va mai inattiva e viene rilasciata. Alla fine il Pool si riempie saranno tutti attivi Connessione e l'applicazione inizierà a lanciare

Allo stesso tempo, quando guardo il database, la maggior parte delle Connessioni è mostrata inattiva. (Configurazione e output dei risultati di seguito)

Sono stato a questo per una settimana e non sono stato in grado di capire la causa principale di questo problema. Ho anche controllato tutti i luoghi in cui è stata creata una connessione e ho fatto in modo che fossero chiusi in seguito.

Quali sono gli altri posti possibili che dovrei esaminare? O si tratta di un bug (o di problemi noti con l'origine dati Wildfly)?

Answer 1

Si scopre che Hibernate teneva la connessione e non li rilasciava al Pool. Indipendentemente dal fatto che stiamo usando il contesto locale del thread. Ma dopo aver aggiunto <property name="hibernate.connection.release_mode">after_transaction</property> alla configurazione di ibernazione. Il problema è stato risolto.

PS: Ancora non capisco perché abbiamo bisogno di definire esplicitamente e perché il release_mode auto non ha voluto rilasciare la connessione una volta che la sessione viene chiusa.
