Starting the lightweight memory leak detection

Use this task to start the lightweight memory leak detection using the 效能和診斷顧問.

Before you begin

If you have a memory leak and want to confirm the leak, or you want to automatically generate heap dumps on Java™ virtual machines (JVM) in WebSphere® Application Server, consider changing your minimum and maximum heap sizes to be equal. This change provides the memory leak detection more time for reliable diagnosis.

About this task

To start the lightweight memory leak detection using the 效能和診斷顧問, perform the following steps in the administrative console:

Procedure

  1. Click Servers > Application servers in the administrative console navigation tree.
  2. Click server_name > 效能和診斷顧問 Configuration.
  3. Click the Runtime tab.
  4. Enable the 效能和診斷顧問 Framework.
  5. Click OK.
  6. From the Runtime or Configuration tab of 效能和診斷顧問 Framework, click Performance and Diagnostic Advice configuration.
  7. Start the memory leak detection advice and stop any other unwanted advice.

Results

The memory leak detection advice is started.

Important: To achieve the best results for performance tuning, start the 效能和診斷顧問 when a stable production level load is running.

Note: 這個主題參照一或多個應用程式伺服器日誌檔。 此外,在分散式和 IBM® i 系統上,另外也建議您可以配置伺服器來使用「高效能可延伸記載 (HPEL)」日誌和追蹤基礎架構,而不使用 SystemOut.logSystemErr.log, trace.logactivity.log 檔案。HPEL 與原生 z/OS® 記載機能也可以一起使用。如果您使用 HPEL,則可以從伺服器設定檔 bin 目錄,利用 LogViewer 指令行工具來存取您所有的日誌和追蹤資訊。請參閱有關利用 HPEL 疑難排解應用程式的資訊,以取得更多使用 HPEL 的相關資訊。

What to do next

You can monitor any notifications of memory leaks by checking the SystemOut.log file or Runtime Messages. For more information, see the Viewing the 效能和診斷顧問 recommendations topic.
