我们正在使用数据库组件中的mule提供的连接池。当我们施加巨大负荷时，我们会低于误差。
将参数配置为：maxConnection = 100，minConn = 0，autoIncrement = 15 waitMillisec = 10000，并且准备好的语句高速缓存大小保持默认值（即没有配置任何内容）。 你可以帮忙解决下面这个问题。

行。
如果您正在使用语句缓存，则如果没有适用于连接的缓存语句，则c3p0会异步获取缓存的语句。在负载很重且没有仔细配置的情况下，由于服务器拥塞或c3p0的线程池拥塞，这种异步获取可能需要很长时间。尝试获取Statement的客户端将无限期地等待，直到成功获取Statement或发生异常。
从根本原因Exception（向下到堆栈跟踪的底部），很明显，在发生可能很长的Statement采集时，将从中获取Statement的Connection很接近（ ）死或死。这就是你需要调试才能真正理解这一点。可能的原因包括：
如果是（3），你应该停止这样做，但我认为这是最不可能出现的情况。如果（1）或（2），您可以缓解问题的主要方法是确保语句获取速度快，以便在我们等待（）获取语句时不太可能发生不良事件。
我要看的第一件事是c3p0的线程池，在你正在申请的负载条件下。它跟上了吗？ （您可以通过JMX或通过调用PooledDataSource方法（例如getThreadPoolNumTasksPending()）来检查这一点。或者，最简单的做法是简单地扩展c3p0配置参数numHelperThreads，因此它更少很可能像Statement收购这样的任务被积压。
另一个可能真正有用的配置更改是确保您允许足够数量的缓存语句来防止搅动（不断关闭（）并重新启动Statement缓存中的Connections）。一个非常频繁的配置错误是将全局maxStatements配置参数设置为太低的值。实现此目的的简便方法是使用maxStatementsPerConnection而不是全局限制，并将其设置为大约应用程序经常使用的数量。
要真正了解正在发生的事情，您将希望了解哪些任务正在积压。再次直接在代码中或通过JMX使用PooledDataSource.sampleThreadPoolStatus()。
更新：在原始帖子中，您声明＆＃34;准备好的语句缓存大小将其保留为默认值＆＃34;。这可能是默认的mule，但c3p0的默认设置根本不使用Statement缓存，maxStatements=0和maxStatementsPerConnection=0。您的配置可能不是您认为的那样。禁用语句缓存可能是解决此问题的一种非常简单的方法。

在保存（插入）第一个对象时，hsqldb (2.4.1)和hibernate (5.3.1)遇到了这个问题。
创建表（DDL）可以，但是保存（SQL准备语句）失败。
我没有应用命名策略，并且休眠显然创建了SQL，其中表名的大小写与hsqldb所期望的不匹配。
Hsqldb区分大小写，尽管人们希望看到一条清晰的错误消息，但报告了上述错误。
此问题已通过添加JPA批注@Table(name="your_table")得到解决。
