Heroku / Play / BoneCp连接问题 [英] Heroku/Play/BoneCp connection issues

问题描述

我有一个应用程序在heroku上使用游戏。它在最长时间内工作正常，但是最近我开始得到这个结果：

 原因：java.sql.SQLException：超时等待免费可用连接。 
 at org.hibernate.engine.jdbc.internal.LogicalConnectionImpl.getConnection（LogicalConnectionImpl.java:169）〜[hibernate-core-4.1.9.Final.jar：4.1.9.Final] 
 at com.jolbox.bonecp.BoneCP.getConnection（BoneCP.java:503）〜[bonecp-0.7.1.RELEASE.jar：0.7.1.RELEASE] 
   
 
  org.postgresql.util.PSQLException引发的
 
 
致命：FATAL ：连接角色太多ejmatdbwywaugk
  
现在，这显然是一个连接泄漏，除了我使用JPA.em（）。 Play例子从未关闭像这样获得的实体管理器。我尝试关闭它，但随后应用程序爆炸说实体管理器已关闭。
 
 
 
有什么想法？ 
 
解决方案
使用BoneCP 0.8.0-rc1并使用此配置： 
 
 
  db。 default.idleMaxAge = 10分钟
 db.default.idleConnectionTestPeriod = 30秒
 db.default.connectionTimeout = 20秒
 db.default.connectionTestStatement =SELECT 1
 db。 default.maxConnectionAge = 30分钟
  
 
I have an app on heroku that uses play. It was working fine for the longest time, but somewhat recently I started getting this:
Caused by: java.sql.SQLException: Timed out waiting for a free available connection.
at org.hibernate.engine.jdbc.internal.LogicalConnectionImpl.getConnection(LogicalConnectionImpl.java:169) ~[hibernate-core-4.1.9.Final.jar:4.1.9.Final]
at com.jolbox.bonecp.BoneCP.getConnection(BoneCP.java:503) ~[bonecp-0.7.1.RELEASE.jar:0.7.1.RELEASE]
which is caused by 
org.postgresql.util.PSQLException: FATAL: too many connections for role "ejmatdbwywaugk"
Now this is pretty obviously a connection leak, except that I'm using JPA.em(). The Play examples never close an entity manager obtained like this. I tried closing it, but then the app blows up saying the entity manager is closed.


Any ideas?
解决方案
Try with BoneCP 0.8.0-rc1 and use this configuration:
db.default.idleMaxAge=10 minutes
db.default.idleConnectionTestPeriod=30 seconds
db.default.connectionTimeout=20 second
db.default.connectionTestStatement="SELECT 1"
db.default.maxConnectionAge=30 minutes
