Oracle Error Message
ORA-19903: test recovery not allowed when recovering to new incarnation
Reason for the Error
Either a new incarnation was set using RMAN’s RESET DATABASE command for a control file that was CURRENT, or the control file is from a prior incarnation. As recovery to a new incarnation requires changing the control file, test recovery is not allowed.
Solution
Perform actual recovery or RESET DATABASE to incarnation that was last opened using the control file to do test recovery.
