Veritabanı bağlantıları wildfly içinde boşta kalma zaman aşımından sonra kapanmaz Veri kaynağı

2015-02-21 18 views

Wildfly 8.1 altında çalışan bir uygulama var Uygulamalarda kullanılan veritabanı bağlantıları standalone.xml dosyasında tanımlı bir Veri kaynağından alınmıştır.Veritabanı bağlantıları wildfly içinde boşta kalma zaman aşımından sonra kapanmaz Veri kaynağı

Sorun: Nedenini bilmiyorum ama Havuz Bağlantısı hiçbir zaman boşta kalmıyor ve bırakılıyor. Sonunda Havuz dolduracak tüm aktif Bağlantı ve uygulama atmaya başlar javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/bo/datasource

Veritabanına baktığımda aynı zamanda Bağlantıların çoğunun boşta olduğu gösterilir. (Yapılandırma ve sonuç çıktısı aşağıda)

Şu an bir hafta boyunca bu konuya girdim ve bu sorunun kök nedenini çözemedim. Ayrıca bir bağlantının oluşturulduğu tüm yerleri kontrol ettim ve daha sonra kapatıldığından emin oldum.

Bakmam gereken diğer olası yerler nelerdir? Yoksa bu bir hata mı (veya Wildfly veri kaynağı ile bilinen sorunlar)?

O döner Hibernate'in bağlantı kurduğunu ve onları Pool'a bırakmayacağını. Konu yerel bağlamı kullandığımızdan bağımsız olarak. Ancak hazırda bekletme yapılandırmasına <property name="hibernate.connection.release_mode">after_transaction</property> ekledikten sonra. Sorun çözüldü.

PS: Bunu açık bir şekilde neden tanımlamamız gerektiğini ve auto shutdown_mode'un oturum kapatıldıktan sonra bağlantıyı neden serbest bırakmayacağını anlayamıyorum.
