IDC3010I
UNABLE TO OPEN dsname

Explanation

The dname specified in the command indicated either concatenated catalogs or a different data set. In the message text:
dsname
The data set name.

System action

The command ends with a condition code of 12.

System programmer response

If the error recurs and the program is not in error, look at the messages in the job log for more information. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM® Support Center. Provide the JCL and the SYSOUT output for the job.

Programmer response

Ensure that the dname specified in the command does not identify a DD statement that defines concatenated catalogs, unless the desired catalog is the first in the concatenation. Ensure that the command and the JCL specify the same data set.
