OpenStack is an excellent cloud operating system, and it is wise for developers, administrators, and operators to have the skills associated with them in their virtual toolkit. Efficient cloud requires an efficient database and can accept multiple databases. But what if you want IBM? DB2 for OpenStack, what should I do? OpenStack does not support DB2 by default.
This short exercise shows how to implement

DB2 database uninstallationSome problems often occur. The following problems are analyzed and corresponding solutions are provided. If you have encountered similar problems when detaching A DB2 database, you may have learned a lot from it.
(1) run the SETUP program from the original installation diskIf you cannot detach a DB2 database from the Add/delete program

establish a client-to-server connection, what are the specific steps?
Step 1:
You must identify the remote server on the client machine. How can this problem be solved? The catalog Method Used in DB2 is to write a remote server in a local client file by cataloguing:
db2catalogtcpipnodep570remote172.10.10.10server50000
In the preceding command, the p570 is a node name (which must be unique on a machine), the remote server is followed by the se
Locate allows users to quickly search the file system for specific files. The approach is to create a database that includes all the file names and paths in the system, and then simply query the database when looking, without actually going into the file system. In the general distribution, the establishment of the database is put into the crontab to execute automatically.

Locate allows users to quickly search the file system for specific files. The method is to set up a database that includes all the file names and paths within the system, and then simply query the database when looking for it, rather than actually going deep into the file system. In the general distribution, the establishment of the database is placed in the crontab automatic execution.1. Command format :Locate
In the process of DB2 development, one of the most important tasks throughout the development process is the maintenance of the database, which is necessary to maintain a large information system; Leave a simple maintenance manual for a rainy year; The following parts of the maintenance order are collected to treat our maintenance engineers and project managers.

WebDriver API: how to locate the elements on the Web page, webdriverapi
Through the front-end tool, we can see a webpage. The elements on the page are composed of a line of code, which are organized hierarchically. Each element has a differentTag NameAndAttribute Value. WebDriver uses this information to find different elements.WebDriver provides eight element locating methods:

The following article mainly introduces how to find out tables and packages without using indexes in DB2. The following article describes the correct operation content, we all know how to locate tables and packages. We all know that in actual operations, the LASTUSED column mainly tells you the last access time of the index in the DB2 database.

Locate, the meaning of positioning, is to allow users to quickly search the system for the specified file.Locate Command features:1"locate"的速度比"find"快,因为它并不是真的查找文件,而是查数据库。2) 新建的文件,我们立即用"locate"命令去查找,一般是找不到的, 因为数据库的更新不是实时的,数据库的更新时间由系统维护。3"locate"命令所搜索的后台数据库在"/var/lib/mlocate"这个目录下, 可能有些Linux系统位置不同,具体我们可以用"

The difference between this method and the previous two methods is that this method usually searches for more than one element, so it is generally recommended to use the Findelements method together. For example, if we want to find out how many buttons are on the page, we can use the button tagname to
