Db2 subsystem storage requirements

You must configure storage sizes for your Db2 subsystem.

You can use the installation CLIST to calculate storage requirements for your Db2 installation. For details, see Calculating storage requirements with the installation CLIST.

If you do not accept the default values, you can calculate the storage that you need for the Db2 data sets by using the information in Active log data sets storage requirements. For other data sets, you can use the formulas in the CLIST. After calculating the required storage for each data set, you can calculate the total requirements.

Although the Db2 libraries require a fixed amount of space, disk requirements for active logs and the Db2 catalog increase with the size of a site. You need additional space for archive logs, image copies, user databases, and other working data sets.
