What is the method for expanding a DB2 tablespace?

There are several ways to expand a DB2 table space: 1. Using the ALTER TABLESPACE statement: You can modify the size of a table space using the ALTER TABLESPACE statement, either increasing or decreasing its size. 2. Using the EXTEND command: You can use the EXTEND command to expand the size of a table space. This command will automatically increase the size when the table space reaches its limit. 3. Using automatic expansion: When creating a table space, you can set parameters for automatic expansion. When the table space reaches its limit, the system will automatically increase its size. 4. Using partitioned table spaces: Partitioned table spaces can be used to expand the size of a table space. These table spaces divide the table data into multiple logical parts, each stored in a different table space, achieving the effect of expanding the table space. These are some common methods for expanding table spaces, and the appropriate method can be chosen based on system requirements. Additionally, when performing table space expansion operations, it is important to backup data to prevent data loss.
