Duplicate Database and RMAN-20208

Question

I'm trying to duplicate an old backup into an auxiliary database. Both the backup and auxiliary are 10g. When I run the following in RMAN:
run {
     set until scn 41429334;
     duplicate target database to aux;
}I get this error:
executing command: SET until clause
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of set command at 05/17/2010 08:54:26
RMAN-06004: ORACLE error from recovery catalog database: RMAN-20208: UNTIL CHANGE is before RESETLOGS changeI'm trying to duplicate from a consistent (cold) RMAN backup and there have been a few OPEN RESETLOGS commands applied to the database as it's a development environment. Is there a way I can get around this issue in the duplicate command. I'd really like to avoid copying over the existing environment as it's currently under heavy use. Any suggestions, links, answers would be appreciated.
Thanks,
John

No, I believe you will get the same error. The cause of the problem is that a RESETLOGS operation was performed after the backup was created so the control file isn't aware of any pre-RESETLOGS operations. Even if you use a Recovery Catalog DB, you'll still get this error.
