Explanation
An error occurred when the key generator utility program attempted to read from or write to the data set identified by ddname in the message. In the message, rc is the return code that identifies the error. If rc identifies a logical error, then FDBK code indicates the specific logical error that has occurred.
System action
Key generator utility processing ends.
System programmer response
For an explanation of the return code and feedback code, see the description of the VSAM macro. Correct the problem and rerun the utility program as follows. If the SETM or CHGM function was requested and the host master key was not set (message ICU010I was not issued), rerun the entire job. Otherwise, use this listing to determine which control statements were processed successfully. Then rerun the utility program using the CHGK function to process the remaining control statements. Notify the security administrator.
To ensure that you have all the messages issued for this problem, specify MSGLEVEL=(1,1) for the job.
