Hi Sarfraz,

go through below link it will help you.

Physical Standby Databases
A physical standby database is physically identical to the primary database. While the primary database is open and active, a physical standby database is either performing recovery (by applying logs), or open for reporting access. A physical standby database can be queried read only when not performing recovery while the production database continues to ship redo data to the physical standby site.

Physical standby on disk database structures must be identical to the primary database on a block-for-block basis, because a recovery operation applies changes block-for-block using the physical rowid. The database schema, including indexes, must be the same, and the database cannot be opened (other than for read-only access). If opened, the physical standby database will have different rowids, making continued recovery impossible.

can I keep Archive log off in standby database


Hope this helps
