This step can be skipped, if a standby database is already present. Dbvisit Standby can work with existing standby databases. To integrate Dbvisit Standby with an existing standby database, skip this section and go to section Dbvisit Standby commands (running or executing Dbvisit Standby). 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.
Dbvisit Standby allows the following options for creating the standby database: a) Regular file system standby database with i) Same structure as primary database or b) ASM standby database (for Oracle version 10.2 and higher) with i) Same structure as primary database or |

If the new standby database has FRA enabled, please remove all files from FRA/<unique_db_name> folder on the standby server, prior to creating the database. This is to avoid resetting the standby database incarnation triggered by the presence of old database files in FRA. |

Standby database spfile/pfile
...
The spfile.ora (pfile.ora for Oracle database version less than 9) is created for the standby database using init.ora or spfile.ora file from the primary database. Oracle database parameters for the standby database can be customised. If an existing init.ora or spfile.ora file is already present on the standby server, it will be overwritten. The Create Standby Database wizard will guide the process and for customizing of Oracle standby database during the creation process. The settings can be saved as a template for future use. If a standby database template has been created previously, then this can be used to create the standby database. No further questions will be asked.
