獲取租戶狀態時出錯

Question

我有一個運行 Stratos 1.5.1 的實例。 在 stratos 坐了一夜而沒有與之交互后，我在登錄 Identity Server 時收到以下消息

我在 url 調用和 user-mgt.xml 的屬性標記中都將 autoReconnect 添加為 true

如果有人知道為什么 autoReconnect 不起作用，那就太好了。 謝謝。

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

糾正這個問題。

這意味着要做的是保持 mysql 連接可用。 這需要我添加這些屬性

wait_timeout=259200

interactive_timeout=259200

和 /etc/my.conf 文件的值。 我重新啟動，然后等待 24 小時進行驗證並再次嘗試登錄，這次成功了。
