The following methods have been tested, in the environment IBM X346,3.2gx2,4g,raid 1,DB2 v8.2.4,win2000 ADV Server,dms tablespace, the data load speed is around 601 million/min.
Background: You need to change the database table space, or you need to migrate the data from all the tables in the database to a new database.
Steps:
1. Select all tables in the source database through the DB2 console (DB2CC) and export them as DDL scripts;
2. Make the necessary modifications to the script as needed
The factory mode is highly efficient in project development, which means to define an interface for creating objects and let the subclass decide which class to instantiate. This is a factory
Next, let's take a simple example:
As shown in, we first define our product abstract class interface, which can also be an abstract class:

The first line of the domain must be written with a "Header", that is, there must be no blank characters (spaces and tabs) on the left side. To continue a line, you must start with a blank character, the first blank character is not inherent in the information. It must be filtered out during decoding. For example, rows 7-8 of Example 2 belong to one domain.
