zk最多存多少个文件

Ⅰ zkteco考勤机u盘怎么导入电脑当天签到在一格

一、U盘下载考勤机上的数据：
A.利用U盘接入考勤机下方U盘口；
B.按考勤设备菜单键进入考勤机主菜单；
C.找到U盘管理→U盘下载→点击下载考勤记录→选择时间段为全部→等待下载完成→返回→找到下载用户数据→等待下载完成→返回，此时可以按照实际情况来选择是否下载其他相应数据，即可完成.dat格式数据下载；

二、上传到ZKtime5.0考勤软件查看并导出Excel报表，具体操作步骤如下：

1）打开U盘文件夹，可以看到xxx_attlog.dat（记录数据）、user.dat（用户数据）两个文件，以及附带的一些文件；

2）打开ZKTime5.0软件→选择USB闪盘管理→选择U盘数据类型→导入用户数据→从U盘导入用户数据→导入步骤1）中的数据→完成→确定；导入完成之后关掉USB 闪盘管理界面。

3）点开出勤记录→选择部门→总公司→人员（全选）→时间（一个月），在界面右边选中简单分析原始记录，再点击查询；这样每个人每天的打卡数据就在一个横排啦；

4）点击界面中间导出→编辑文件名即可导出对应Excel报表；

操作示意图如下：

Ⅱ 如何提高zookeeper每个结点所能存储的数据大小

今天发现一个问题，zookeeper默认对每个结点的最大数据量有一个上限是1M，如果你要设置的配置数据大于这个上限将无法写法，在网上查了一圈发现有一个解决方案如下，增加-Djute.maxbuffer=10240000参数

最终提供一个完整的修改后的zkServer.sh文件如下
