# Using Customized HUB

By default, the CICS region uses the system default HUB, the default value is the SMF ID of the LPAR. If you want to use a different HUB, you must add a DDName statement to the CICS region startup PROC in the following format:

`//HUBxxxx DD DUMMY`

where`xxxx` is the HUB name which you want to be used for this CICS region.
