-------------------------------------- 

任何人都可以告訴我爲什麼我得到這個錯誤。

以下是我的設置。

• 非活動連接超時：60
• 連接預訂超時：20
• 初始容量：10
• 最大CapacityL：30

我仿形連接泄漏也和我檢查在我的應用程序中沒有開放連接。

謝謝，

Answer 1

您已泄漏連接。沒有關閉它。它變得不活躍，但不在游泳池中。一段時間後，WLS注意到連接實際上處於非活動狀態，即泄漏，並強行關閉它，將其返回到游泳池。

這裏是連接打開的地方：

com.ura.dams.registration.dbcontrol.SubmissionUploadDBImpl.executeSelect(SubmissionUploadDBImpl.java:786) 

檢查代碼，看看如何接近（）不叫。

Answer 2

作爲一種解決方法，我告訴這個解決方案要在WLS中完成。在WLS數據源配置中，不活動連接超時配置將出現在高級配置下。我們必須把它變成了0。

步驟來達到非活動連接超時是： 登錄到WLS - >點擊數據源 - >選擇配置選項卡 - >點擊DATA_SOURCE名 - >選擇連接池的配置下選項卡 - >點擊高級鏈接頁面的底部下 - >無效連接超時值更改爲從任何其他值。

該配置將刪除所有不活動的連接意味着它不會等待關閉連接，當它將達到非活動狀態。希望這會有所幫助。
