BCV 5 - Fast Database Cloning

Cloning of DB2 databases and tablespaces is a sophisticated and error prone process. Lots of input statements for the utilities must be tailored, jobs have to be scheduled and if you want to refresh an existing environment you have to be sure that the structures of the objects are compatible.

But the biggest pain is the runtime.

Conventional methods like UNLOAD/LOAD require a lot of CPU time and IO. The copy process takes hours and days.

This implicates that the copy process cannot be done in the limited batch window. The constantly increasing amount of data makes it more difficult to do copies in a regular way.
