Check for duplicate class names

Description: When new classes are shipped with RACF®, you should verify that any installation-defined class names that have been added to the class descriptor table (CDT) do not conflict with the new classes. For a list of new classes shipped with RACF, see z/OS Summary of Message and Interface Changes.

Steps to take: Verify that any installation-defined class names that have been added to the class descriptor table (CDT) do not conflict with the new classes.

If you have duplicate class names, RACF issues the following message and enters failsoft mode:

ICH564A RACF DETECTED AN ERROR IN THE INSTALLATION CLASS DESCRIPTOR TABLE,
ENTRY class_name, ERROR CODE 7

If a conflict in class names occurs, resolve it as follows:
1. Delete the profiles in the installation-defined class with the conflicting name.
2. Delete the CDT entry for the class.
3. Add a CDT entry with a different name.
4. Redefine the profiles.
