Oracle Database Discussions

Hi gurus,

I am planning to duplicate my production database (Server A) using the cold backup taken from RMAN on the Server B. The whole process should be done through RMAN using NOCATALOG mode.
I have transfered the backupsets to the Server B, with the same directory location as of Server A. I want to keep the DB name, and the file location same as the "Production DB".

I started the server B using the Pfile created from Server B's SPFILE.

SQL> *startup nomount pfile='/u01/app/oracle/db/dbs/initcentral.ora';
ORACLE instance started.*
