db2move是一个集成式的数据移动工具,它支持导出(export)、导入(import)、装入(load)三种操作方式。其实db2move的这三种工作方式分别是通过简单使用db2 export, db2 import, db2 load指令来完成的。
此部分仅仅介绍其export功能,import和load将在稍后的部分介绍。使用db2move导出的数据文件格式是IXF。
建立并进入数据存放目录:
$ mkdir /home/backup/mydata
$ cd /home/backup/mydata
导出指定的数据库中的全部数据:
$ db2move testdb export –u db2inst1 –p thepasswd
说明:
1,这将会把数据库testdb中的全部数据提取到当前目录(/home/backup/mydata)中。每个表的内容都存储在一个.ixf文件中,每个.ixf文件都有一个与之相对应的.msg文件,.msg文件是描述从表中导出数据时的信息的。另外还有两个文件,db2move.lst用来记录.ixf文件、.msg文件与表的一一对应关系,EXPORT.out记录的是导出数据时的屏幕输出。
2.导出表结构,命令行如下:
db2look -d dbname -e -a -x -i username -w passWord -o ddlfile.sql
3.导出表中数据
export to [path(例:D:"TABLE1.ixf)] of ixf select [字段(例: * or col1,col2,col3)] from TABLE1;
例如:EXPORT TO "data/DBMEMUSE_WATCHER.ixf" OF IXF MESSAGES "data/DBMEMUSE_WATCHER.txt" SELECT * FROM DBMEMUSE_WATCHER;

DDREASE is a tool for recovering data from file or block devices such as hard drives, SSDs, RAM disks, CDs, DVDs and USB storage devices. It copies data from one block device to another, leaving corrupted data blocks behind and moving only good data blocks. ddreasue is a powerful recovery tool that is fully automated as it does not require any interference during recovery operations. Additionally, thanks to the ddasue map file, it can be stopped and resumed at any time. Other key features of DDREASE are as follows: It does not overwrite recovered data but fills the gaps in case of iterative recovery. However, it can be truncated if the tool is instructed to do so explicitly. Recover data from multiple files or blocks to a single

The performance of JAX, promoted by Google, has surpassed that of Pytorch and TensorFlow in recent benchmark tests, ranking first in 7 indicators. And the test was not done on the TPU with the best JAX performance. Although among developers, Pytorch is still more popular than Tensorflow. But in the future, perhaps more large models will be trained and run based on the JAX platform. Models Recently, the Keras team benchmarked three backends (TensorFlow, JAX, PyTorch) with the native PyTorch implementation and Keras2 with TensorFlow. First, they select a set of mainstream
