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

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

: Network Disk DownloadIntroduction DB2 database is the core product of IBM's relational database, and it is widely used both domestically and globally. For DB2 beginners, the "Step DB2:DBA system Management, operation and application case" gradually introduced the many concepts and knowledge DB2 involved to everyone.

/DB2cmd client developed by the DB2 database does not have the command history function. The postgresql client can edit historical commands; Q. DB2 cannot install different database versions on the same machine. postgresql can; R, DB2 has the concept of a federated database, and postgresql does not; S and DB2 II can re

, the table space in which the table is located is placed in the backup pending state, where the tables can be SELECT, but not the UPDATE and DELETE operations. In order for the table state to return to normal, you must manually perform a backup command on its tablespace to remove the suspend state. Because this option is the default option, if not specified in the LOAD command, the default is to use this option, such as:E:\TESTGT;
