If there are changes to the category 2 transactions, you must rerun the DFH$CAT2 CLIST provided
in the SDFHSAMP library.
For information about the changes to the CICS main terminal transaction CEMT, see Changes to CEMT.

DFHRSURI now specifies TRANSCTION(CPIW) instead of CPIH. If you are using a customized version of
DFHRSURI that no longer specifies TRANSACTION(CPIH), no action is needed and you can continue to use
your customized DFHRSURI unchanged.
However, if the CSD is being shared with a back level
region, and if the CICS-supplied DFHWSAT group has been
installed (instead of a customized DFHRSURI), take one of the following actions:
- Make sure authority is given to run CPIW.
- Install a customized version of DFHRSURI that specifies TRANSACTION(CPIH), ahead of the DFHWSAT
group.
