For Oracle version 12.2.0.1.0, cloning a container database (CDB) fails for "instant mode" snapshots.
The cloning fails with the following error message:
SFDB vxsfadm ERROR V-81-0564 Oracle returned error.
Reason: ORA-01157: cannot identify/lock data file 5 - see DBWR trace file
ORA-01110: data file 5: '/data/DB12R2/pdbseed/system01.dbf'
Workaround: There is no workaround for this issue. Alternatively, you can use online or offline mode snapshots.
