Key data set requirements
You must perform the following tasks for the key data set:
Create the key data set.
requires that the key data set be a fixed or fixed block physical sequential data set with a logical record size (LRECL) of 80.
requirements for the contents of the data set are specified in Key-data-set-contents. Any variation from these requirements could prevent
from encrypting the image copy.
Identify the key data set to
.
The KEYDSNAM installation option specifies the key data set name. After you specify the key data set name,
dynamically allocates the data set when it is needed. If
attempts to encrypt an image copy and you have not specified the key data set name in the installation option module,
issues the following warning message, sets the condition code to 4, and produces plaintext image copies.

Periodically, you may want to change encryption keys. You cannot edit the key data set while any utility that is using the key data set is inflight. You need to schedule time to maintain the data set. You must take care when you maintain the data set because incorrect entries in the data set might prevent
from encrypting your image copies or prevent
from recovering using your encrypted image copies.
Provide appropriate security for the key data set to protect it from unauthorized access.
Maintain backups of your key data set either with DFSMShsm or some other facility.
