There are some general rules for creating labels for CKDS key records.
- Each label can consist of up to 64 characters. The first character
must be alphabetic or a national character (#, $, @). The remaining
characters can be alphanumeric, a national character (#, $, @), or
a period (.).
- Labels must be unique for all key types except EXPORTER,
IMPORTER, IPINENC, PINGEN, PINVER, and OPINENC
- Labels must be unique for any key record, including transport
and PIN keys, created or updated using the dynamic CKDS update services.
KGUP and the dynamic CKDS update services, unless they are modified
by user-written exits, check for uniqueness according to these rules
prior to making any change to the CKDS.
