A new LNKLST set without the data sets is not sufficient. The old LNKLST 
set will still be active, and the data set still in use. See topic "Removing or 
compressing a data set in an active LNKLST set" in the MVS Initialization 
and Tuning reference. In order to be effective, after creating and activating 
the new LNKLST set, you need to issue

LNKLST UPDATE JOB(*)

so that no active address space using the old LNKLST set.

However, be aware that doing so involves risk. Many of us have done so and 
gotten away with it, but if you are unlucky, you may have to IPL to recover 
from the errors that were caused.
