How to continue a broken duplicate database

 Hi,

I'm duplicating a production DB to a test DB on the same Node, both 10.2.0.2.

Everything worked fine until the SET UNTIL clause.

executing command: SET until clause
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of set command at 05/08/2009 09:21:49
ORA-01858: a non-numeric character was found where a numeric was expected

because I forgot to set the NLS_DATE_FORMAT format in the shell.

...I know that there is a to_date function...

Is there a way to continue the duplication or do I have to start all over again?

regards
