اجرای دستور duplicate برای ایجاد بانک جدید(دیتابیس تستی و یا دیتاگارد چندم) بر روی بانک اصلی ممکن است سبب ایجاد کندی در آن شود، در صورتی که از قبل دیتاگاردی در این محیط پیکربندی شده باشد، می توان با کمک ان، از بار ناشی از ایجاد دیتابیس جدید در بانک اصلی جلوگیری کرد.
اجرای دستور duplicate در محیط دیتاگارد(برای ایجاد دیتاگارد دوم و یا دیتابیس جدید) در اوراکل 11g هم امکان پذیر است منتها تغییر در دیتاگارد سبب می شود تا عملیات duplicate به صورت کامل انجام نشود و در نتیجه باید در زمان اجرای دستور duplicate، از ارسال آرشیولاگ جدید به دیتابیس جلوگیری کرد و یا انکه دیتاگارد را از حالت recover خارج نمود همچنین snapshot standby هم می تواند از گزینه ها باشد، در غیر این صورت، ممکن است اجرای دستور duplicate با خطا همراه باشد:
–in 11g

}
executing Memory Script
RMAN-03002: failure of Duplicate Db command at 11/20/2018 12:06:33

RMAN-03015: error occurred in stored script Memory Script
RMAN-06136: ORACLE error from auxiliary database: ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: ‘/u01/oracle/oradata/dupstb/DUPSTB/datafile/o1_mf_system_prtimipp_.dbf’
همچنین دیتاگارد باید در وضیعت open قرار داشته باشد:
–in 11g
RMAN> duplicate target database to dupstb from active database;
RMAN-03002: failure of Duplicate Db command at 11/20/2018 11:47:28
RMAN-05501: aborting duplication of target database
RMAN-05531: a mounted database cannot be duplicated while datafiles are fuzzy
در اوراکل 12cR2، می توان دستور duplicate را بدون محدودیتهایی آن در اوراکل 11g، در محیط دیتاگارد(چه در حالت mount و چه در حالت ADG) اجرا کرد(برای ایجاد دیتاگارد چندم و یا دیتابیس جدید):
SQL> select status from v$instance;
