IMPDSSIZE in macro DSN6SYSP

Specifies the maximum data set size (DSSIZE) in gigabytes that DB2® should use for creating an implicit base table space.

This parameter is not used for the creation of implicit LOB or XML table spaces. Valid settings are 1, 2, 4, 8, 16, 32, 64, 128, and 256.

The default value of IMPDSSIZE is 4, unless you use SAP.

If you specify an SAP-specific input member (for example, DSNTIDXB) during installation or migration, the DSNTIJUZ job that is generated by the DB2 CLIST specifies IMPDSSIZE=64.
