zk最多存多少個文件

Ⅰ zkteco考勤機u盤怎麼導入電腦當天簽到在一格

一、U盤下載考勤機上的數據：
A.利用U盤接入考勤機下方U盤口；
B.按考勤設備菜單鍵進入考勤機主菜單；
C.找到U盤管理→U盤下載→點擊下載考勤記錄→選擇時間段為全部→等待下載完成→返回→找到下載用戶數據→等待下載完成→返回，此時可以按照實際情況來選擇是否下載其他相應數據，即可完成.dat格式數據下載；

二、上傳到ZKtime5.0考勤軟體查看並導出Excel報表，具體操作步驟如下：

1）打開U盤文件夾，可以看到xxx_attlog.dat（記錄數據）、user.dat（用戶數據）兩個文件，以及附帶的一些文件；

2）打開ZKTime5.0軟體→選擇USB閃盤管理→選擇U盤數據類型→導入用戶數據→從U盤導入用戶數據→導入步驟1）中的數據→完成→確定；導入完成之後關掉USB 閃盤管理界面。

3）點開出勤記錄→選擇部門→總公司→人員（全選）→時間（一個月），在界面右邊選中簡單分析原始記錄，再點擊查詢；這樣每個人每天的打卡數據就在一個橫排啦；

4）點擊界面中間導出→編輯文件名即可導出對應Excel報表；

操作示意圖如下：

Ⅱ 如何提高zookeeper每個結點所能存儲的數據大小

今天發現一個問題，zookeeper默認對每個結點的最大數據量有一個上限是1M，如果你要設置的配置數據大於這個上限將無法寫法，在網上查了一圈發現有一個解決方案如下，增加-Djute.maxbuffer=10240000參數

最終提供一個完整的修改後的zkServer.sh文件如下
