In DB2, table space automatic expansion can be set up by following these steps:

  1. Identify the type of tablespace: First, determine the type of tablespace where automatic expansion will be set up. In DB2, there are different types of tablespaces such as system tablespaces, temporary tablespaces, user tablespaces, and index tablespaces. Different types of tablespaces may require different settings for automatic expansion.
  2. Check the current status of the table space using the following command.
db2 list tablespaces show detail

This will display detailed information about all tablespaces in the database, including their current size and usage.

  1. Set the automatic expansion option for the tablespace using the following command:
ALTER TABLESPACE <tablespace_name> AUTORESIZE YES

Replace with the name of the tablespace you want to enable automatic expansion for. This will allow the tablespace to automatically expand when it reaches its maximum size limit.

  1. Set the automatic extension parameters for the tablespace using the following command:
ALTER TABLESPACE <tablespace_name> MAXSIZE <max_size>

Replace with the name of the tablespace for which you want to set the autoextend parameter, and replace with the maximum size limit of the tablespace. This parameter specifies the maximum size of the tablespace, and when the tablespace reaches this size, automatic extension will stop.

  1. Verification Setup: Use the following command to double check the detailed information of the table space to ensure that the automatic expansion option and parameters have been successfully set.
db2 list tablespaces show detail

This completes the automatic extension setting for the tablespace.

Please note that the automatic extension options and parameters for table spaces may vary depending on the version and configuration of DB2. Therefore, it is recommended to consult the relevant DB2 documentation or a DB2 administrator for accurate setup steps before making any changes.
