This step can be skipped, if a standby database is already present. Dbvisit Standby can work with existing standby databases. Dbvisit Standby will automatically register the existing standby database. Dbvisit Standby does not distinguish between an existing standby database and a standby database created through Dbvisit Standby.

Dbvisit Standby can automatically create the standby database. The standby database will reside on the standby server and is an exact binary copy of the primary database.
The standby database only needs to be created once. After the standby database is created, Dbvisit Standby will automatically ensure the standby database is kept up to date with the primary database.
Dbvisit Standby normally uses the network to transfer the primary database to the standby server to create the standby database. For slow networks or very large databases, use the transportable media creation method to create the standby database. 
The primary database will not be shutdown during standby database creation. Dbvisit Standby uses RMAN in most cases to make a backup of the primary database.
Perquisites for creating the standby database are:

1. Oracle software must be installed on the standby server.
2. Enough free space on the standby server must be available for the standby database.
3. The Oracle background (cdump, udump, bdump etc ) and admin directories are created. These directories can be created by Dbvisit Standby if you choose the option to create missing filesystem directories automatically

Dbvisit Standby allows the following options for creating the standby database:

1. Regular file system standby database with

i) Same structure as primary database or,
ii) Different structure as primary database.

1. ASM standby database (for Oracle version 10.2 and higher) with

i) Same structure as primary database or
ii) Different structure as primary database.
