IDC1631I DUPLICATE ‘SYS1. DATA SET NAME’ IN TARGET CATALOG

Explanation
A duplicate SYS1. data set entry was found in the
virtual storage access method (VSAM) or integrated catalog facility
(ICF) catalog while attempting to convert an OS catalog entry.

System action
An accompanying message identifies the entry not
converted. The system does not convert the entry.

System programmer response
If the error recurs and the program
is not in error, 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
If duplicates exist and the one on the control
volume (CVOL) is the copy wanted in the target catalog, then delete
the copy in the target catalog prior to issuing the CNVTCAT command.
