"test recovery not allowed when recovering to new incarnation"
*Cause: 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.
*Action: Perform actual recovery or RESET DATABASE to incarnation
that was last opened using the control file to do test recovery.
