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).
For a complete overview of creating the standby database, please see Start the Dbvisit Standby command console from the Start Menu > Programs > Dbvisit > Standby.
1. To create a standby database, choose option 7.

E) Exit
=========================================================
Please enter choice : 7
2. Choose the primary database to create a standby for. Only Dbvisit Standby configured databases will be shown :
=>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:
Database w120n is up.
Total database size for w120n is 23GB
Transferring dbv_functions to host WINDEV-02:dbv_functions
Transferring dbvisit to host WINDEV-02:dbvisit
Transferring dbvisit_setup to host WINDEV-02:dbvisit_setup
Transferring dbv_oraStartStop to host WINDEV-02:dbv_oraStartStop
Transferring dbv_w120n.env to host WINDEV-02:dbv_w120n.env
Transferring dbv_ORACLE_SID.env to host WINDEV-02:dbv_ORACLE_SID.env
Transferring README.txt to host WINDEV-02:README.txt
Checking Oracle installation on WINDEV-02 in
C:\oracle\product\10.2.0\db_1…
Total database size for w120n is 830MB
What would you like to do:
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
5 - Terminate processing
Please enter your choice [2]: 1
Starting creation of standby database.
4. An ASM (for Oracle versions 10.2 or higher) or normal file system standby database can be created:
------------------------------------------------------------------------------
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):
------------------------------------------------------------------------------
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:
------------------------------------------------------------------------------
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:
------------------------------------------------------------------------------
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:
------------------------------------------------------------------------------
The following oracle database parameters will be set in the standby database pf
le or spfile:
-------------------------------------------------------------------------------
audit_file_dest C:\ORACLE\ADMIN\W120N\ADUMP
background_dump_dest C:\ORACLE\ADMIN\W120N\BDUMP
compatible 10.2.0.1.0
control_files C:\ORACLE\ORADATA\W120N\CONTROL01.CTL,
C:\ORACLE\ORADATA\W120N\CONTROL02.CTL,
C:\ORACLE\ORADATA\W120N\CONTROL03.CTL
core_dump_dest C:\ORACLE\ADMIN\W120N\CDUMP
db_block_size 8192
db_file_multiblock_read_count 16

-------------------------------------------------------------------------------
What would you like to do:
1 - Proceed with creating the standby database
2 - Edit oracle database parameters for the standby database pfile/spfile
3 - Terminate processing
Please enter your choice [1]:
Validating oracle database parameters... please wait
SUCCEEDED
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:
------------------------------------------------------------------------------
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.
To create non OMF redo logs Dbvisit requires you to specify valid filesystem
locations on the standby.
Review and confirm standby locations to create standby non OMF redo logs.
-------------------------------------------------------------------------------
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.
10. Provided answers can be stored as a template for future use (re-running creating of a standby database):
------------------------------------------------------------------------------
=>Create standby database template for w120n using provided answers?
<Yes/No> [Yes]: y
An existing template found.
=>Do you want to view the existing template? <Yes/No> [Yes]: n
What would you like to do:
1 - Keep existing template and continue with creating a standby database
using provided answers
2 - Save provided answers as a new template (Note: existing template
will be replaced by the new one)
Please enter your choice [1]: 2
What would you like to do:
1 - Continue with creating a standby database
2 - Terminate creating a standby database. The saved template will be
available for future use
Please enter your choice [1]:
11. The standby database will now be created. Once completed the next stepsto take will be shown:

To complete creating standby database, run dbvisit on the primary and standby
databases to ensure standby database is in synch with primary.
Please press <Enter> to continue...
=========================================================
Standby Database creation on WINDEV-02 completed.
Next steps:
1) Exit out of dbvisit_setup.
2) Run Dbvisit on this server with command:
dbvisit database_name
3) Run Dbvisit on standby server with command:
(cd E:\users\oracle\Avisit\Products\Dbvisit\Development\dbvisit\standby)
dbvisit database_name
Once Dbvisit has been tested, schedule Dbvisit on primary and standby servers
using windows "Scheduled Task" or other scheduling tool.
