摘要

Linux 上 SQL 資料庫引擎的平均等待時間 (毫秒)

導致等候的各個鎖定要求之平均等候時間 (毫秒)。此計數器以資料庫引擎計數器為依據，且單一 SQL 執行個體的所有資料庫對此計數器都具有相同的值。

此為取得鎖定的平均等待時間 (毫秒)，值愈低愈好。如果值超過 500，則可能會發生封鎖，您有可能需要找出封鎖的原因並加以修正。

可覆寫的參數

名稱	描述	預設值
已啟用	啟用或停用該工作流程。	是
間隔 (秒)	每次重複執行工作流程之間的時間間隔 (秒)。	900
逾時 (秒)	指定流程被關閉及標示為失敗之前，允許執行的時間。	300
資料庫連線的逾時 (秒)	若工作流程無法在指定的期限之內存取資料庫，將會失敗並登錄一則事件。	15
