Dear list,

It's my understanding that the schema will be created if it does not exist before a data pump import.
If that is true, why the impdp command below failed and I had to create the schema for it to work?

Thanks,

Roger Xu

$ impdp system/xxxxxx SCHEMAS=TSDBA \
> directory=pump_dir dumpfile=tsdbaups60d0pump.dmp \
> logfile=tsdbaups60d0pump.imp
