获取租户状态时出错

Question

我有一个运行 Stratos 1.5.1 的实例。 在 stratos 坐了一夜而没有与之交互后，我在登录 Identity Server 时收到以下消息

我在 url 调用和 user-mgt.xml 的属性标记中都将 autoReconnect 添加为 true

如果有人知道为什么 autoReconnect 不起作用，那就太好了。 谢谢。

You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Answer 1

我按照指示

http://www.lahiru.org/2010/07/keep-live-connection-in-wso2-products.html

纠正这个问题。

这意味着要做的是保持 mysql 连接可用。 这需要我添加这些属性

wait_timeout=259200

interactive_timeout=259200

和 /etc/my.conf 文件的值。 我重新启动，然后等待 24 小时进行验证并再次尝试登录，这次成功了。
