If an automatic extension is set up for the last HiRDB file of a user LOB RDAREA and that HiRDB file is placed in frozen update status, the automatic extension of the RDAREA is disabled. If you add HiRDB files and extend the user LOB RDAREA, the automatic extension is operable.

You cannot set up an RDAREA automatic extension if the last HiRDB file of the user LOB RDAREA is in frozen update status. You must add HiRDB files and set up the RDAREA automatic extension when you extend the user LOB RDAREA.
