RMAN Duplicate - SPFILE Clause

Hi All

We have one question on the RMAN Duplicate command specifically the SPFILE clause

This is for 19c

Prior to the duplicate, when we start up the AUX / STANDBY instance, we are thinking of starting it up with a minimalist init.ora like this

DB_NAME=PRODDB

DB_UNIQUE_NAME=STANDBYDB

CLUSTER_DATABASE=FALSE

AUDIT_FILE_DEST= location on the standby server

Then startup the AUX instance

And connect to the target and aux database using RMAN from the AUX / Standby server and then issue the duplicate database command using the SPFILE clause and then change the settings of some of the standby parameters like log_file_name_convert,db_file_name_convert etc
