Notes for cross-platform database migration of DB2 databases (1)

This article introduces you to the correct procedures for cross-platform database migration of DB2 databases, as well as the considerations we need to pay attention to when implementing the actual migration of cross-platform databases of IBM DB2.

Suppose you are the administrator of a DB2 commercial database system. You are assigned a task to support the continuous development of business systems by the business development and testing teams, creating a database system independent of the product environment for them, so as not to affect the daily business operations. For various reasons, this development and testing database system will run in an operating system different from the product environment.

We know that DB2 provides some convenient database management tools, such as the overall backup and recovery functions of the database, you can use it to easily migrate an IBM DB2 database from one physical node to another. However, DB2's backup and recovery functions currently only support migration between homogeneous operating system platforms, for example, from windows to windows, from AIX to AIX. There is no dedicated tool for cross-platform database migration required by the preceding tasks.

Migration steps

After the author's practice, the procedure for cross-platform migration of the DB2 database is summarized as follows:

Record the configuration parameters of the source database management system for system tuning after migration;

Check the source database system objects and specify the database system objects to be migrated;

Export the dataset of the source database system;

Generate the data object Definition Statement of the source database system;

Create a new database on the target platform and set it according to the source system;
