There are many ways to replicate data in DB2 database, this paper mainly introduces a scheme of cloning DB2 data using fast disk replication technology (such as flashcopy, etc.). By using DB2 cloning Tool, you can minimize the actions that DBAs need to perform during the DB2 database cloning process. Make the entire pr

sort cache. The amount of memory is limited, how these memories can be effectively utilized is crucial to the efficient performance of DB2. DB2 data administrators need to pay special attention to the configuration of DB2 system parameters, whether through the DB2 command or DSNZPARMs. For performance optimization, th

To migrate data from the mainframe to DB2 UDB on the AIX platform, the process is usually as follows: log on to the mainframe, extract data to a file, and ftp file to the AIX machine, then load the data to DB2 UDB. This requires two different working environments. The alternative is: by using only one script, I can com

DB2 data administrators need to pay special attention to the configuration of DB2 system parameters, whether through the DB2 command or DSNZPARMs.

With the increasing efficiency and productivity of enterprises, DBAs have to complete their daily work with higher quality and management efficiency while reducing the number of DBAs. DBAs also have more requirements for professional management tools that support heterogeneous environments and have specialized management functions. Quest central for DB2 provides integrated management functions to help users complete routine DBA functions in an increas

This part is simple and clear at a glance. Five different permission levels: sysadm, sysctrl, sysmaint, dbadm, and loadBut I have read that there is sysmon in CFG, which may be mentioned later (to obtain access to database system monitor data)Or the version is not updated. The following aspects of the DB2 authorization control database security plan:* Permission level granted to a user* Commands that can be run by users* Allows users to read and/or m

advantageous relational database becomes the mainstream of the market. Then, in 1974, Ray Boyce and Don Chamberlin of IBM presented the SQL language, which implemented all the operations of the database lifecycle and laid another milestone for the relational database. In 1979, IBM completed the first DBMS to implement SQL. In the early 80 of the 20th century, IBM took advantage of the second phase of RDBMS and SQL technology to create a new database product named

The following articles mainly introduce you to the basic DB2 commands and related knowledge that you must master as a beginner in DB2 database learning. We all know that you are in the DB2 database getting started course, some friends mentioned this question, and experts answered it and compiled it to help other friends learn and master it. Common

The latest version of Strobe provides a more comprehensive view of DB2. With Compuware's rich understanding of DB2 products and long-term experience, strobe and iStrobe also play a key role in effectively controlling MIPS usage and identifying possible cost savings. Compuware configurationnasdaq: CPWR) provides a series of enhanced improvements to its Strobe 4.1 and iStrobe 4.1 products, helping customers s

Fortunately, DB2 provides the related USEREXIT Program (also known as the user exit Program), which allows us to manage log files and has the possibility of extended functions. At this point, DB2 is obviously better than Orac. Fortunately, DB2 provides the related USEREXIT Program (also known as the user exit Program), which allows us to manage log files and has

The following article describes how to create a second DB2 instance in the command line status in the DB2 database under the linux operating system, the following describes the actual operation steps for creating a DB2 instance. We hope this will help you in your future study. In DB2 in linux, create the second

DB2 has three main security mechanisms to help DBAs implement database security plans: Authentication, authorization, and privilege ). Five different permission levels: sysadm, sysctrl, sysmaint, dbadm, and load A new concept in DB2 9 is tag-based access control (lbac) that allows control of who has the right to access individual rows and/or columns.

Today I saw a group of friends asked two questions comparison basis:1 How to confirm my DB2 is the root What about the installation? In fact, from DB2 UDB V9.1 have db2ls This command, the problem is much simpler, we just need to simply run down the db2ls, and then see the output of the Installer UID is 0(Root uid), as shown in:[[email protected] ~]$ db2lsinstall Path level Fix Pack Special install number i
