Enabling trace at server startup
Use the administrative console to enable tracing at a server's startup. You can use trace to assist you in monitoring system performance and diagnosing problems.
About this task
The diagnostic trace configuration settings for a server process determines the initial trace state for a server process. The configuration settings are read at server startup and used to configure the trace service. You can also change many of the trace service properties or settings while the server process is running.
You
can also configure tracing from the MVS™ console
using the modify command.

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.log、SystemErr.log, trace.log 及 activity.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。
