No. Some of the DDDEF might be part of a SYSLIB or STEPLIB entry or other. The TLIBs and DLIBs plus global should be all you need.
The best way to do this, 1) Backup all the GLOBAL/TLIBs/DLIBs before you apply maintenance 2) If you have not done an accept since the last APPLY, do that now 3) Then do the apply. Now you have a point in time recovery point Or you can also do something called a zone roll process. Set up your SMP/e environment for 3 functions What's new and going in The maintenance that is rolling out to your systems The maintenance that is in production and will roll off Call the three zones XZONE new products or maintenance goes here YZONE validated maintenance from the XZone ZZONE Once it gets to your production system. Then copy the Yzone to the zzone You would apply the maint to you xzone and test it. Once it is verified you would then apply that maintenance to your YZone and install on your next system. Of course, this will depend on how you want to set things up. Once you start to roll out your Yzone you would pick a point when the zzone should get updated. This way you have backups, backouts, and validation systems. Requires more dasd and more attention to detail, but I have seen this used effectively.
