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.

Because only SYSADM users are allowed to update DBM CFG files, only they can grant any sys* permission to other groups. The following example shows how to grant SYSADM permissions to the DB2GRP1 Group:

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

This time, our DB2 is deployed on Windows. Windows has a client that is called a graphical interface. But it does not seem to work well, we have some problems, let's solve it.
First, add a database instance:
Instances of DB2 are independent of each other, and instances can be considered as containers for databases. When the default
