congestion_fail_window

更新时间：2026-07-22 16:50:58

分享

congestion_fail_window 用于设置 OceanBase 数据库服务器出错统计周期，与congestion_failure_threshold 配合使用。

如果在设置的错误统计周期内错误次数超过了 congestion_failure_threshold 的值，则将该 OBServer 节点加入黑名单。

说明

该参数值一旦修改，当前错误统计计数会被清零，将重新按新的 fail window 从头开始统计错误次数。

属性	描述
参数类型	时间类型
默认值	120s
取值范围	[1s, 1h]
是否重启 ODP 生效	否
