Again, I don't see this as a problem. Apparently either does IBM since the
migration guide recommends removing CUN* members from parmlib.
Although this if from the z/OS 1.8 migration manual, it applies to z/OS 1.7 with
APAR OA14231 installed also:
"Remove CUNUNIxx parmlib members
Timing: Before the first IPL of z/OS V1R8.
Is the migration action required?
No, but recommended to help avoid confusion in the future by anyone who
encounters Unicode parmlib members and is unaware that they are no longer
necessary. "

No debate there. Perhaps it is this problem (I ran into this during my z/OS
1.8 migration last year):

ERROR DESCRIPTION:
An address space can fail if there are problems loading the DB2
image.
.
For example, starting two DB2 address spaces simultaneously may
result in one address space failing because only one of them
can load the prebuilt DB2 Unicode image. Starting the DB2
address spaces a minute apart will prevent this problem.
For example, when the dataset containing the prebuilt DB2 image,
SYS1.SCUNIMG, is not in the linklist. This may cause the
character conversion request to fail.
.
Customer may see DSNT552I -DBxx DSNZINIT CHARACTER CONVERSION
FROM CCSID 37 TO CCSID 1208 FAILED WITH ERROR CODE 24.
LOCAL FIX:
Start the second DB2 address space after a few minutes of the
first DB2 address space initializing successfully.
PROBLEM SUMMARY:
****************************************************************
* USERS AFFECTED: Users of the Unicode Services prebuilt DB2 *
* image, SYS1.SCUNIMG(CUNIDHC2). *
****************************************************************
* PROBLEM DESCRIPTION: Unicode Services may fail to load the *
* prebuilt DB2 image because dataset *
* SYS1.SCUNIMG(CUNIDHC2) is not in an *
* APF-authorized library. This failure *
* is considered to be a user error. *
* When this failure happens, Unicode *
* Services should continue operation *
* with an empty Unicode environment and *
* try to dynamically load the requested *
* conversion. The problem is that the *
* character conversion service fails *
* instead of trying to load the requested *
* conversion. *
* *
* Subsequent conversion attempts may *
* succeed. *
****************************************************************
* RECOMMENDATION: Fix the problem so that the prebuilt DB2 *
* image SYS1.SCUNIMG(CUNIDHC2) can be loaded *
* by Unicode Services. Refer to IBM *
* publication SA22-7649, "Support for Unicode: *
* Using Unicode Services", chapter 2. *
* . *
* If that cannot be done, apply the fix for *
* this problem, so conversions will be loaded *
* dynamically. *
****************************************************************
PROBLEM CONCLUSION:
This corrects the character conversion service so that when
the DB2 image fails to load, the character conversion
service proceeds with an empty Unicode environment, and
conversions are loaded dynamically.
