Question

我正面临Payara服务器4.1.1.164的问题。

在日志中，我发现错误连接首先重置，然后所有连接都无法使用错误连接已关闭。

我需要重新启动我的应用程序以恢复所有内容，如果不这样做，连接将不会重建。

以下是调用堆栈，抱歉我必须隐藏查询。

我怎样才能重播此错误或如何避免相同的错误？

Answer 1

该消息是由于数据层（JDBC）中的套接字连接出错而引起的。如果连接池在应用程序服务器中具有可靠的连接数，请查看连接池，如果使用SSL，请检查应用程序服务器和数据库服务器中的TLS版本。

Answer 2

为避免在GlassFish中遇到JDBC连接失败，首先，您可以增加连接池超时。我认为您的数据库非常繁忙，无法在特定时间内响应GlassFish请求，因此无法正确处理您的连接。确保您的数据库服务器正在运行，并且您有足够的资源（RAM，CPU，连接）。

其次，您可以在使用之前验证连接池，也可以在连接池中进行配置。

使用资源＆gt;下的管理控制台设置JDBC连接池属性JDBC＆gt;连接池＆gt;缓冲池名称

超时设置 有两种超时设置： - 最长等待时间。 - 空闲超时。

连接验证设置 如果为true，则池在将连接提供给应用程序之前验证连接（检查以确定它们是否可用）。但是，缺点是，要求连接验证强制服务器在每次池返回连接时应用验证算法，这会增加getConnection（）

的延迟的开销。

Java，Glassfish，连接已关闭
