Datenbankverbindungen nicht geschlossen nach dem idle-timeout in wildfly Datasource
Ich habe eine Anwendung unter wildfly 8.1
Die Datenbank-verbindungen verwendet in den Anwendungen genommen werden, die aus einer Datenquelle definiert standalone.xml Datei.
Problem: ich weiß nicht warum, aber die Verbindung aus dem Pool geht nie im Leerlauf und veröffentlicht werden. Schließlich wird der Pool gefüllt wird, werden alle aktiven Verbindung und-Anwendung gestartet werfen javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:/bo/datasource
Zur gleichen Zeit, wenn ich einen Blick in die Datenbank, die meisten der Verbindungen sind gezeigt zu werden, im Leerlauf. (Konfigurations-und Ergebnis-Ausgabe unten)
Wurden ich diese für eine Woche jetzt und nicht in der Lage gewesen, um herauszufinden, die Ursache von diesem problem. Ich habe auch überprüft, alle Orte, an denen eine Verbindung erstellt wird und sichergestellt haben, dass Sie danach geschlossen.
Was sind die anderen möglichen Orte, die ich suchen sollte, in? Oder ist das ein bug (oder bekannte Probleme mit Wildfly datasource)?
