Configuring the service log
The settings for service logs are typically shared for all servers, but you can configure a separate service log for each server process by overriding the configuration values at the server level.
About this task
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.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。
In WebSphere Application Server Version 7 and earlier, the service log is enabled by default. In WebSphere Application Server Version 8x, however, the service log is disabled by default. Configure your servers to use HPEL log and trace mode and use the HPEL API if you need to be able to merge log file content from multiple servers. Use the HPEL log, trace mode and the HPEL LogViewer command if you need to be able to render log content in Common Base Event XML format.
