ICU1015 UNABLE TO [OPEN | CLOSE ] ddname [CODE rc]
Explanation
The key generator utility program was unable to open or close the data set defined by the DD statement identified by ddname.
If the data set is a VSAM data set (SYSCKDS or SYSNCKDS), the VSAM return code rc is included to help identify the error. For the explanation of the return code, see the description of the VSAM macro. This message is accompanied by a VSAM error message that further identifies the problem.
System action
Key generator utility processing ends.
Programmer response
If the problem occurred while trying to open a data set, check the JCL. Be sure the required DD statements were included, that they have the correct ddnames, and that they define the correct data sets. The following ddnames are valid: SYSCKDS, SYSNCKDS, SYSIN, and SYSMKDS.
Correct the problem and rerun the key generator 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.
To ensure that you have all the messages issued for this problem, specify MSGLEVEL=(1,1) for the job.
