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.
Perquisites for creating the standby database are:
- Oracle software must be installed on the standby server.
- Enough free space on the standby server must be available for the standby database.
- The Oracle background (cdump, udump, bdump etc. ) and admin directories are created.These directories can be created by Dbvisit if you choose the option to create missing filesystem directories automatically.
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
ii) Different structure as primary database. b) ASM standby database (for Oracle version 10.2 and higher) with i) Same structure as primary database or
ii) Different structure as primary database. |

The creation of the standby database can be done either through the command line interface (CLI) or the web based graphical user interface (GUI). The CLI commands are indicated with a

The example below shows how to create standby database on the fly (by direct transfer to the standby server). Creating a standby database is performed on the primary server (primary node).

2. Choose the primary database to create a standby for. Only Dbvisit Standby configured databases will be shown :
| Section |
|---|
| Column |
|---|
| | Panel |
|---|
| =>Creating Standby Database.
Primary database will NOT be shutdown.
For which primary database do you want to create a standby database?
The following Oracle database(s) have a Dbvisit Database configuration (DDC) file on this server:
SID
===
1) w120n
3) Return to menu
Please enter choice : 1
Is this correct? <Yes/No> [Yes]: |
|
|
3. The primary database must be up and running for the setup to proceed. Total size of the primary database is calculated and displayed. The Dbvisit Standby installation files are also copied to the standby server initially. If uncompleted creation of the standby database is detected, a restart option will be available. Standby database can also be created using a saved template:
| Section |
|---|
| Column |
|---|
| | Panel |
|---|
| Database w120n is up.
Total database size for w120n is 23GB

1 - Create standby database (and optionally save settings in template)
2 - Restart the uncompleted creation of standby database
3 - Create standby database using existing template (previously saved)
4 - Help

4. An ASM (for Oracle versions 10.2 or higher) or normal file system standby database can be created:
| Section |
|---|
| Column |
|---|
| | Panel |
|---|
| ------------------------------------------------------------------------------
Do you want to create an ASM standby database (with all or some database files
in ASM storage)? [No]: n
Standby database will be ASM: N
Is this correct? <Yes/No> [Yes]: |
|
|
5. It is possible to transfer datafiles directly to the standby server, but only if both primary and standby databases are filesystem, and the primary database does not contain Oracle Managed Files (OMF):
| Section |
|---|
| Column |
|---|
| | Panel |
|---|
| ------------------------------------------------------------------------------
You can create a standby database by transferring the database files directly
to the standby server,
or by copying them to a temporary local location first. By using a temporary
location the time taken to place the database in backup mode is reduced.
If the database is very large then use a temporary location (answer No).
If either a primary or a standby database is ASM, you have to use a temporary
location (answer No).
Do you want to copy database files directly to the standby server? [Yes]:
Database files will be copied directly to the standby server: Y
Is this correct? <Yes/No> [Yes]: Y |
|
|
6. It is possible to use secure shell (SSH) compression "on the fly" during transfer of the database files. Using SSH compression may speed up the transfer if the network is slow, however it may take additional CPU cycles:
| Section |
|---|
| Column |
|---|
| | Panel |
|---|
| ------------------------------------------------------------------------------
Use ssh compression to compress the database files during transferring? [Yes]:
Database files will be compressed during transferring: Yes
Is this correct? <Yes/No> [Yes]: |
|
|
7. It is possible to create missing filesystem directories on the standby server automatically:
| Section |
|---|
| Column |
|---|
| | Panel |
|---|
| ------------------------------------------------------------------------------
Dbvisit has functionality to create missing filesystem directories on the standby server automatically.
Do you want Dbvisit to create missing filesystem directories on the standby automatically? [Yes]: Dbvisit will create missing filesystem directories automatically:Y
Is this correct? <Yes/No> [Yes]: |
|
|
8. Oracle database parameters for the standby database can be customised:
| Section |
|---|
| Column |
|---|
| | Panel |

9. It is possible to specify the locations of standby datafiles, redo logs and tempfiles different as primary, or alternatively keep the same structure for the standby database as primary:
| Section |
|---|
| Column |
|---|
| | Panel |
|---|
| ------------------------------------------------------------------------------ Primary database contains non OMF datafiles and/or tempfiles. To create non-OMF standby datafiles and/or tempfiles Dbvisit requires you to provide valid filesystem locations on the standby. Review and confirm standby locations to create standby non-OMF datafiles and tempfiles. ------------------------------------------------------------------------------- Primary ===> Standby ------------------------------------------------------------------------------- C:\ORACLE\ORADATA\W120N ===> C:\ORACLE\ORADATA\W120N ------------------------------------------------------------------------------- What would you like to do: 1 - Confirm standby location(s) are correct and continue 2 - Provide different standby location(s) Please enter your choice [1]: Standby locations validated Primary database contains non OMF redo logs.
