RMAN: specification does not match any datafile copy in the repository

We copied one file from production Exadata to standby Exadata:

$ rman target / auxiliary sys@DWH_STB

Recovery Manager: Release 12.1.0.2.0 - Production on Thu Sep 21 14:26:52 2017

connected to target database: SPUR (DBID=496990843)
auxiliary database Password:
connected to auxiliary database: SPUR (DBID=496990843)

RMAN> run
2> {
3> allocate           channel prmy01 type disk PARMS="BLKSIZE=10485760";
4> allocate           channel prmy02 type disk PARMS="BLKSIZE=10485760";
5> allocate auxiliary channel stby01 type disk PARMS="BLKSIZE=10485760";
6> allocate auxiliary channel stby02 type disk PARMS="BLKSIZE=10485760";
7> backup as copy

RMAN> list copy of datafile 790;

specification does not match any datafile copy in the repository

RMAN> list copy of datafile 824;

specification does not match any datafile copy in the repository



Where are these two files ? Why such files are absent ?
Solution: Oracle don't register datafiles copied via auxiliary channels.
So you cannot find these files nether in prod or standby controlfiles.

And therefore you should remove these files manually.
