RMAN Duplicate database command failed with following error message.
Here is the work around for this issue.
Add the following parameter to the auxiliary database init<dbname>.ora file and startup with nomount option for duplicate database. Rerun the duplicate command with noresume option. The value for these parameters should be same as the max value allowed in the error message.
In case above attempt fails you have to take a fresh backup from the TARGET database by setting the following variable. Use the new SCN number from the new backup for the duplicate database. Also set the same init variable in Auxiliary database before starting the duplicate command. i.e: synchronize the variable values in both TARGET and AUXILIARY database.
