There are two formats of the PKDS: original and KDSR. Both formats use the same LRECL. The KDSR format provides support for metadata for each record including tracking usage of the record. To convert the original format PKDS to KDSR format, see Migrating to the KDSR format key data set.
For information on managing and sharing the PKDS in a sysplex environment, see z/OS Cryptographic Services ICSF Administrator's Guide.
The process of re-enciphering the PKDS is different for IBM zEnterprise 196 or newer servers.
For additional information on ME and CRT tokens, see Diagnosis reference information.
