1. Introduction
In this section, we will cover a few of the advanced topics with regards to Dbvisit Standby version 8 and Oracle RAC configurations.
In this section, the concepts will be explained by use of an example.
1.1. Different types of Oracle RAC configurations
Dbvisit Standby version 8 handles Oracle RAC configurations different than previous installations.
It is important to take note of this and not attempt a version 7.0.x to 8.0.x upgrade without knowing this as you will not be able to perform a direct upgrade.
If you are moving from version 7 to version 8, you MUST create a new DDC file. You will not be allowed to upgrade the current version 7 DDC file if Oracle RAC is being detected.
Dbvisit Standby version 8 is designed to be more Oracle RAC aware. This include
- Run Dbvisit Standby on only one of the Oracle RAC nodes
- To allow for this use a new Virtual IP - to be created and assigned to run on the preferred node of your choosing. This allows Dbvisit Standby to treat the cluster as "one" node. Example, if the VIP is 10.0.2.79 and the name attached to this is dbv-vip. We can anywhere on the network (as long as dbv-vip for 10.0.2.79 is in the DNS) ping or attempt a connection to dbv-vip and it will always run on one of the RAC nodes, it does not make a difference which one. The VIP will run on the node where the Dbvisit Standby components are running. That way you do not have to configure Dbvisit Standby on all the RAC nodes, but only on one. Which is the much more effective and better use of resources?
- If this preferred node fails for some reason, switch the dbv-vip (Virtual IP) and the Dbvisit components (resources) to the second node (using action scripts and adding these components as cluster resources).
- Now to achieve this configuration, as you might have guessed, Shared storage is used. This allows the software to be installed once, configured to use the Virtual IP (example dbv-vip) and then you can switch between the nodes (after resources have been configured and added to Clusterware).
- Shared Storage can be ACFS, NFS or possibly any other cluster filesystem. This filesystem will store the Dbvisit Software as well as copies of the Archive Logs during certain phases of Dbvisit Standby use, depending on your configuration.
- It is recommended that the Dbvisit ARCHSOURCE and ARCHDEST be located on shared storage. (Remember when a Graceful Switchover - role reversal is performed, the ARCHSOURCE and ARCHDEST parameter values are swapped. So make sure that ARCHSOURCE is located on the shared storage. This is where archive logs will be stored when the RAC cluster becomes a standby - and if on shared storage, both nodes can perform recovery (whichever one would be running the Dbvisit Standby resources at the time).
- Note: this does not mean you cannot use local storage. The downside is if you use local storage and not shared storage, you can only run of one node unless you implement something like "rsync" to synchronize the local folder for the node 1 (maybe node 1 is your preferred node) to the secondary node 2. That way you have the resources for Dbvisit Standby running on node 1 and all files are synced with node 2 (using "rsync" and a "CRON" schedule). This is not a perfect solution but is an option if you really cannot implement the use of shared storage.
On this page:
2. Example 1: Oracle RAC Primary to Single Instance Standby
Two Options are available, using shared storage on the Oracle RAC cluster for the Dbvisit Standby installation, or using local storage and run of only one node and optionally configure "rsync" to have the Dbvisit Standby folder synced between the primary nodes.
The two diagrams below explain the configuration in more detail:
2.1. Option 1 - Recommended - Using Shared Storage
2.2. Option 2 - Using Local Storage
The diagram below provides an overview of the Architecture:
To explain the configuration further we will use an example. Below is a diagram that provides high-level details for the environment:
The key parts to note:
- The primary RAC Cluster consists out of two nodes (kiwi1 and kiwi2)
- The first node (kiwi1) will be used as the node to run Dbvisit Standby on local storage
- The "Dbvisit Base" folder "/usr/dbvisit" will be synced between the primary node kiwi1 and kiwi2 using the "rsync" utility and a CRON schedule.
- The standby server is a single instance system using Filesystem Bases storage:
- /u01/app/oracle/oradata1 --> this location will hold the database files (OMF - Oracle Managed Files will be used), this location will also hold a copy of the redo logs (OMF)
- /u01/app/oracle/oradata2 → This location will hold the second copy of the redo logs
- /011/app/oracle/fast_recovery_area . → This location will be used as the recovery area on the standby server
The Dbvisit Standby locations are:
- DBVISIT_BASE = /usr/dbvisit
- ARCHSOURCE = /u01/app/oracle/dbvisit_arch/DEV
- ARCHDEST = /u01/app/oracle/dbvisit_arch/DEV
Now that we have an overview of the configuration, we can start with the installation.
We will install Dbvisit Standby software on node 1 (kiwi1) and on the standby server (kiwi221).
The installation of the software on kiwi1 will be synced later (see 2.2.4 below).
2.2.1. Installing the Software
Below is an example of installing the Dbvisit Standby software onto a local folder - the default which is /usr/dbvisit
Remember in this example, the VIP on the RAC Cluster is running on kiwi1 and is called "dbv-vip"
We first install the software on node 1 (kiwi1) and then on the standby node (kiwi221).

between the RAC nodes. Dbvisit Standby will only run on the server where this virtual hostname (VIP) resource is running.
The Virtual Hostname (and VIP) should be configured as a resouce in clusterware and must be enabled and started on one of the nodes before yo
continue with the setup. If you are not using a Virtual Hostname (Highly Recommended), Dbvisit Standby can only be configured to run on one
dedicated node in the RAC configuration - specify the hosts name here if you do not have a Virtual Hostname (attached to VIP) for the cluster
configured.
For non-RAC configurations specify the standby database server name here.

oracle@kiwi1[/usr/dbvisit/standby]: ls conf
dbv_DEV.env dev.db
From the above example, we can see that we now have a DDC file called "dbv_DEV.env" and a repository for this DDC file called "dev.db".
2.2.2.2. Using the Central Console
Below are the screenshots showing you how you can use the Central Console to create the DDC file for this configuration:
Step 1: Open Main Screen, and navigate to manage hosts and first add the two hosts (dbv-vip and kiwi221)
Step 2: Add a new host
Step 3: Add the RAC node 1 (kiwi1) - but not the host details - you must use the RAC VIP that we assigned - this allows us to move to kiwi2 without having to update names as we use the Virtual IP (dbv-vip) which moves between them.
Step 4: Review host and click add new to add standby host - kiwi221
Step 5: Add kiwi221 host
Step 6: Review hosts
Step 7: Add new DDC → navigate to Manage Configurations
Step 8: Start new DDC process by selecting "NEW"
Step 9: Fill in the required details:
Once the details are provided, click on Submit and the DDC file will be created.
Step 10: Review the DDC file
Step 11: Make sure you apply your License key for this newly created DDC before you move onto the Create Standby Database (CSD)
2.2.3. Creating the Standby Database (CSD)
This example will only show using the Central Console.
It is possible to create the standby database either via the Command Line Interface (CLI) using the command: ./dbvctl -d <DDC> --csd in this example: "./dbvctl -d DEV --csd"
To use the Central Console, navigate to the Central Console page and follow the steps as outlined below:
Step 1: Navigate to the Create Standby Database (CSD) Menu
Step 2.1: Select the DDC, Create New Database option and update the Database SPFILE parameters to match the Standby server configuration:
In this example, the standby is Filesystem Based Storage
As we are using OMF - Oracle Managed Files on ASM (Which is recommended) we have to adjust the OMF parameters according - see 3,4,5 and 6 as marked below:
Step 2.2: Review Temporary Backup Locations - Make sure that this location has sufficient space for a full RMAN compressed backup of the database. In this example /usr/tmp has sufficient space on both the primary and standby.
2.2.4. Initial Send/Apply Logs
This section will show you how you can send/apply logs following the CSD process.
This can be done either via the Command Line Interface or the Central Console.
2.2.4.1. Using the Command Line Interface (Send/Apply)

Step 2: Select the DDC, click on [2] Send Logs icon and an Active Task will appear [3] which will turn to a green tick when done. View the details by clicking on the task [3] and you will see the details [4]
Step 3: Select the DDC, click on the Apply Logs icon [2]. The active task will be created [3] and when selected the details will be displayed [4]
2.2.5. Use "rsync" to sync local storage on RAC nodes
The next step in this example is to use the UNIX "rsync" utility to copy the files located in the /usr/dbvisit directory (The DBVISIT_BASE) from the "preferred node" which is the node where Dbvisit Standby normally is set to run, which in this example is "kiwi1". It will be set to copy the files from this location to the secondary node kiwi2 in this example. From kiwi2 there will be no Dbvisit Standby processes running as the Virtual IP (dbv-vip) will be running on kiwi1.
You will only start the Dbvisit Processes on kiwi2 if the Virtual IP cluster resource (dbv-vip) has been switched over - (re-allocated or failed over) to run on kiwi2. For more detail on configuration of the VIP and the Action Scripts for Dbvnet and Dbvagent please see here - Oracle RAC Configurations#OracleRACConfigurations-5.Example2:AddDbvnetandDbvagentasClusterResources
Note: The /usr/dbvisit directory (The Dbvisit Base) location must exist on both Primary RAC nodes and that the permission of this folder is set to have the "oracle" Unix account (the user that runs your database software) as the owner. At this stage, the folder on the secondary server (kiwi2) will be empty as we have not synced the files yet.
Step 1: Create a "rsync" script
The first step now is to create a script that will be used to copy the files from node 1 (kiwi1 in this example) to node 2 (kiwi2).
IMPORTANT
Please note that this example of showing how "rsync" can be used.
These steps and scripts must be tested and modified to suit your environment prior to implementing it into production.
Make sure that you disable the rsync schedule prior to running a Graceful Switchover - it can be re-enabled again after that.
Sample "rsync-dbvisit" script
Note - this script can be copied into a folder /home/oracle/bin and enabled via a UNIX CRON schedule to run on a regular basis.
#!/bin/bash
#
# Note this is a sample script and it must be modified to suit your environment.
# Test this script before implementing into a production environment.
# Basic script to sync /usr/dbvisit local with remote /usr/dbvisit directory.
# This script: rsync-dbvisit will be located in /home/oracle/bin folder.
#
#
remote_server=kiwi2
dbv_base_log=/tmp/rsync-dbvisit-base.log
dbv_arch_log=/tmp/rsync-dbvisit-arch.log
echo "Start Sync: `date`" > ${dbv_base_log}
## Run the rsync command over SSH
## options used are to preservice times, have a 2min i/o timout and to exclude trace files
##
rsync -aqzte ssh --exclude '*.trc' --log-file=${dbv_base_log} /usr/dbvisit/ oracle@${remote_server}:/usr/dbvisit/
echo "End Sync: `date`" >> ${dbv_base_log}
echo "Start Sync: `date`" > ${dbv_arch_log}
## We also need to sync the ARCHSOURCE and ARCHDEST location if on local storage and not shared
rsync -aqzte ssh --exclude '*.trc' --log-file=${dbv_arch_log} /u01/app/oracle/dbvisit_arch/DEV/ oracle@${remote_server}:/u01/app/oracle/dbvisit_arch/DEV/
echo "End Sync: `date`" >> ${dbv_arch_log}
Once you have created this script, make sure that it has sufficient permissions and that the owner "oracle" user, in this case, have a execute permission (example "chmod +x oracle rsync-dbvisit" ). For more detail please see the "chmod" command man pages or online help for your UNIX distribution.
The above script is making use of the UNIX "rsync" command. For more details on the use of this command and all parameters please see the UNIX man pages or online documentation.
Once you have created the script you can run it manually the first time to ensure the directories are kept in sync.
oracle@kiwi1[/home/oracle]: cd bin oracle@kiwi1[/home/oracle/bin]: ./rsync-dbvisit
Then review the log file in /tmp/dbvisit-rsync.log as well as the /usr/dbvisit directory on the secondary server (kiwi2 in this example)
Step 2: Schedule the Script
In this example, we will schedule the script to run every 10 minutes. This should be sufficient for most configurations.
The schedule can be adjusted if required based on your configuration and environment.
## # CRON: Synchronize the Dbvisit Base folder between kiwi1 and kiwi2 ## */10 * * * * cd /home/oracle/bin; ./rsync-dbvisit >>/dev/null 2>&1
To schedule, a cron use the "crontab -e" command and to view any existing schedules use "crontab -l"
Step 3: Monitor
Have Dbvisit Standby run either via a schedule or via the Daemon process for a period and then monitor the /usr/dbvisit folder on the standby server.
You should see files being updated in the secondary server following a run of the above schedule.
2.2.6. Next Step - Scheduling
The next step is to schedule Dbvisit Standby or to run the Daemon process.
Both methods can be used.
Example if you want to run the Schedule using the Unix Cron, you can use the following example CRON entries:
On the Primary (kiwi1)
## # CRON: Synchronize the Dbvisit Base folder between kiwi1 and kiwi2 ## */10 * * * * cd /home/oracle/bin; ./rsync-dbvisit >>/dev/null 2>&1 ## ## # Dbvisit Standby Scheduled to run every 5 min */5 * * * * cd /usr/dbvisit/standby; ./dbvctl -d DEV >>/dev/null 2>&1
On the Standby (kiwi221) - apply logs every 15min, this can provide a buffer (delay in applying logs) to possibly stop Human error (deletion of data etc).
## # Dbvisit Standby Scheduled to run every 15 min */15 * * * * cd /usr/dbvisit/standby; ./dbvctl -d DEV >>/dev/null 2>&1
For more detail on scheduling or running Dbvisit Standby as a background Daemon/Process please see here - Dbvisit Standby Scheduling
2.2.7. Example Graceful Switchover in this Configuration
This example is just to show Graceful Switchover that was performed on this environment.
Before the Graceful Switchover (GS) a log gap report was run to make sure that the primary and standby is up to date.
oracle@kiwi1[/usr/dbvisit/standby]: ./dbvctl -d DEV -o switchover
=============================================================
Dbvisit Standby Database Technology (8.0.08.18506) (pid 2736)

=============================================================
dbvctl ended on dbv-vip: Mon Jan 23 15:56:57 2017
=============================================================
Following this process, kiwi221 is now a single instance primary with kiwi1/kiwi2 as the standby database.
3. Example 2: Oracle RAC primary to Oracle RAC standby
In the example we will discuss in this section we will explain the configuration of a Standby Oracle RAC environment for a Primary Oracle RAC environment.
The Diagram below provide a summary of the environment:
3.1. The Primary Oracle RAC Configuration - Overview
In the example the primary RAC configuration exists out of two Nodes:
- Primary node 1: kiwi81
- Primary node 2: kiwi82
The IP address details are listed below:
## Public IP addresses 10.0.2.81 kiwi81.oraclekiwi.co.nz kiwi81 10.0.2.82 kiwi82.oraclekiwi.co.nz kiwi82 ## Virtual IP Addresses 10.0.2.83 kiwi81-vip.oraclekiwi.co.nz kiwi81-vip 10.0.2.84 kiwi82-vip.oraclekiwi.co.nz kiwi82-vip ## Private Interconnect Addresses 10.5.5.81 kiwi81-priv.oraclekiwi.co.nz kiwi81-priv 10.5.5.82 kiwi82-priv.oraclekiwi.co.nz kiwi82-priv ## SCAN address list in DNS Only # 10.0.2.85 kiwi812-scan.oraclekiwi.co.nz kiwi812-scan # 10.0.2.86 kiwi812-scan.oraclekiwi.co.nz kiwi812-scan # 10.0.2.87 kiwi812-scan.oraclekiwi.co.nz kiwi812-scan # Dbvisit Standby VIP 10.0.2.89 kiwi812-vip.oraclekiwi.co.nz kiwi812-vip
These details are added to the /etc/hosts file as well as to the DNS.
Having the values in the DNS is highly recommended.
The Oracle SCAN details must be in the DNS.
3.1.1. The new Virtual IP
Take note of the new Virtual IP that is specified. This new Virtual IP is created and will be assigned to one specific node at a time. But it can move between the RAC nodes. Dbvisit Standby version 8 will be configured to use this address as the "cluster address". That way we can decide on which node we want Dbvisit Standby components to run.
- Get new IP address on the public network (network used by Primary/Standby)
- Create new Cluster Resource – Virtual IP (as root user)
- Review Oracle Documentation on creating a Virtual IP!
The steps to create the Virtual IP address is listed below (Note these are executed as the root user)
# appvipcfg create -network=1 -ip=10.0.2.89 -vipname=kiwi812-vip -user=root # crsctl setperm resource kiwi812-vip -u user:oracle:r-x # crsctl setperm resource kiwi812-vip -u user:grid:r-x # crsctl start resource kiwi812-vip -n kiwi81 # crsctl status resource kiwi812-vip -p # crsctl relocate kiwi812-vip # crsctl relocate resource kiwi812-vip -n kiwi81
The last step is to make sure you add to the DNS: 10.0.2.89 kiwi812-vip

4. Example 2: The Core Component Installation
4.1. Primary Cluster - Node 1 (kiwi81)
- The primary cluster Virtual IP is 10.0.2.89 and is using the hostname alias kiwi812-vip. We will use this as the SOURCE address name for the Primary Cluster.
- At the time of installing the software, the Virtual IP was configured to run on node 1 - kiwi81.
- The steps below explain the installation of the Dbvisit Standby Core components - Dbvnet, Dbvagent and Dbvisit Standby CLI
- Dbvisit Standby components are installed onto the shared storage which is mounted under /acfs directory
- The directory /acfs/dbvisit and /acfs/dbvisit_arch is created and the "oracle" Unix account is made the owner
In this example, a basic passphrase of "kiwi123" is used for Dbvnet and the Dbvagent

4.2. Standby Cluster - Node 1 (kiwi92)
- The standby cluster Virtual IP is 10.0.2.99 and is using the hostname alias kiwi912-vip. We will use this as the SOURCE address name for the Primary Cluster.
- At the time of installing the software, the Virtual IP was configured to run on node 1 - kiwi91.
- The steps below explain the installation of the Dbvisit Standby Core components - Dbvnet, Dbvagent and Dbvisit Standby CLI
- Dbvisit Standby components are installed onto the shared storage which is mounted under /acfs directory
- The directory /acfs/dbvisit and /acfs/dbvisit_arch is created and the "oracle" Unix account is made the owner
- In this example, a basic passphrase of "kiwi123" is used for Dbvnet and the Dbvagent

5. Example 2: Add Dbvnet and Dbvagent as Cluster Resources
In this section, we will show you how to add Dbvnet and Dbvagent as cluster resources.
We will make use of an action script for each component, which will then be used to manage these two resources.
Note: these scripts are provided as examples and should be tested in your development or test environments before implementing it into production as each environment is different and they might need to be adjusted for your environment.
5.1. Dbvnet Action Script
The script below is a sample action script that will be used to manage dbvnet.
This script is created in the dbvnet folder /acfs/dbvisit/dbvnet

if [ $RET -eq 0 ]; then
exit 0
else
exit 1

5.3. Add the Cluster Resources
On the Primary cluster node 1 (kiwi81) as the root user run the following commands to add the two resources:
IMPORTANT: The lines below should be on one line, but are shown on separate lines to make it easier to read
crsctl add resource dbvnet -type cluster_resource
-attr "ACTION_SCRIPT=/acfs/dbvisit/dbvnet/action-script.scr, RESTART_ATTEMPTS=3, START_TIMEOUT=60, STOP_TIMEOUT=60, CHECK_INTERVAL=10,
START_DEPENDENCIES='hard(kiwi812-vip) pullup(kiwi812-vip)'
,STOP_DEPENDENCIES='hard(kiwi812-vip)'
ACL='owner:oracle:rwx,pgrp:oinstall:rwx,other::r--'
PLACEMENT='favored'
HOSTING_MEMBERS='kiwi81'"
crsctl add resource dbvagent -type cluster_resource
-attr "ACTION_SCRIPT=/acfs/dbvisit/dbvagent/action-script.scr, RESTART_ATTEMPTS=3, START_TIMEOUT=60, STOP_TIMEOUT=60, CHECK_INTERVAL=10,
START_DEPENDENCIES='hard(kiwi812-vip) pullup(kiwi812-vip)'
,STOP_DEPENDENCIES='hard(kiwi812-vip)'
ACL='owner:oracle:rwx,pgrp:oinstall:rwx,other::r--'
PLACEMENT='favored'
HOSTING_MEMBERS='kiwi81'"
On the Standby cluster node 1 (kiwi91) as the root user run the following commands to add the two resources:
IMPORTANT: The lines below should be on one line, but are shown on separate lines to make it easier to read
crsctl add resource dbvnet -type cluster_resource
-attr "ACTION_SCRIPT=/acfs/dbvisit/dbvnet/action-script.scr, RESTART_ATTEMPTS=3, START_TIMEOUT=60, STOP_TIMEOUT=60, CHECK_INTERVAL=10,
START_DEPENDENCIES='hard(kiwi912-vip) pullup(kiwi912-vip)'
,STOP_DEPENDENCIES='hard(kiwi912-vip)'
ACL='owner:oracle:rwx,pgrp:oinstall:rwx,other::r--'
PLACEMENT='favored'
HOSTING_MEMBERS='kiwi91'"
crsctl add resource dbvagent -type cluster_resource
-attr "ACTION_SCRIPT=/acfs/dbvisit/dbvagent/action-script.scr, RESTART_ATTEMPTS=3, START_TIMEOUT=60, STOP_TIMEOUT=60, CHECK_INTERVAL=10,
START_DEPENDENCIES='hard(kiwi912-vip) pullup(kiwi912-vip)'
,STOP_DEPENDENCIES='hard(kiwi912-vip)'
ACL='owner:oracle:rwx,pgrp:oinstall:rwx,other::r--'
PLACEMENT='favored'
HOSTING_MEMBERS='kiwi91'"
5.4. Start the Dbvnet and Dbvagent Cluster Resources
The following commands can be used to check the status of the cluster resources as well as to start and stop them.
Remember that these two resources are dependant on the Virtual IP address that was added.
If the Virtual IP address is moved (relocated) to the other node, the Dbvnet and Dbvagent resources will be stopped and moved to the other node and started.
IMPORTANT
After the dbvagent resource is started, check USER variable in its environment, for example:
xargs --null --max-args=1 < /proc/<pid>/environ | grep USER
If the result is:
USER=root
Then you will need to add one extra line to change this variable to the dbvagent action script:
...
case "$1" in
'start')
export USER=oracle
./dbvagent -d start
...
Restart dbvagent resource afterwards
- Status Check

6. Example 2: Create the Dbvisit Standby DDC File
There are two methods to create the Dbvisit Standby DDC file.
In this example, we will show it via the Central Console.
The Central Console is installed onto its own system and have network access to both the Primary and the Standby RAC clusters.
6.1. Add the two new hosts
The two hosts to be added is the Dbvagent connections, which is to the Virtual IP addresses.
6.2. Start the DDC creation process
Navigate to the Configurations screen and start the creation of the new DDC
The New Configuration will now start as seen below:
- Select the source as the primary Virtual IP - kiwi812-vip, then accept the license agreement
- Select the source Instance Name - this is obtained from the /etc/oratab file. We need to make sure you have both the Database and the Instance on the specified system in the /etc/oratab file. Select the instance name, in this case, it will be DEV1
- Specify the ARCSOURCE location. This location should ideally be located on the shared storage location. Remember when a Graceful Switchover is performed the roles are reversed between the ARCSOURCE and the ARCHDEST values in the DDC file
- Specify to use DBVNET by default (recommended)
- You will now be presented with the primary RAC database details, review and confirm the database and ASM instances match the servers they are running on. Dbvisit Standby will detect these values based on the connection that was made to the primary instance that was selected in step 2 above.
- As we are going to create a standby RAC database, we will adjust this setting to YES. See the next screenshot below
From the above image we can see:
- Specify the standby database will be a RAC enabled environment
- Select the standby Virtual IP hostname - kiwi912-vip
- You are then presented with the RAC Thread details for node 1 and 2 on the standby server, fill in the required detail
- Specify the ARCHDEST location - this should be on shared storage and is the location where Dbvisit Standby will transfer archive logs into on the standby server.
- Review and update the Dbvisit Base location on the standby server if different
- Review the Oracle Database Home on the standby server
- Review and update the DB Unique Name (db_unique_name) of the standby if required - default value recommended
- Specify the Dbvisit Standby Configuration (DDC) name
The last step is to click on Submit.
Dbvisit Standby will now validate the parameters specified and create a new DDC file as well as a repository (stored in the DBVISIT_BASE/standby/conf directory)
7. Example 2: Create the Standby Database
The standby database can either be created via the command line interface (dbvctl -d <DDC> --csd) or via the Central Console.
In this example, we will show the use of the Central Console to create the standby database
- Navigate to the "Create Standby Database" Menu
- Select the DEV DDC file from the dropdown list.
- Then specify the process option as "NEW DATABASE"
The server parameter file (spfile) section does contain a lot of information. Make sure you review the locations of the datafiles, redo logs and spfile.
In this example, the primary and standby systems match exactly from a storage point of view (same disk groups etc) so we do not have to change any parameters.
From the above, we can see that the temporary location /user/tmp was used for the local and remote temp backup locations.
Make sure the locations you specify has sufficient space to hold a full compressed database backup.
In this example, the "Create Standby Database & Template" option is selected.
The new task will be created as shown below:
8. Example 2: Send Logs from Primary to Standby
- Navigate to the Database Actions Screen
- Click on the option to "Send Logs"
- Review the Task details
9. Example 2: Apply Archivelog to Standby
- Navigate to the Database Actions Screen
- Click on the option to "Apply Logs"
- Review the Task details
10. Oracle RAC on Windows
This section will include additional information and recommendations when installing Dbvisit Standby version 8 on an Oracle RAC configuration on Windows.
Please review Oracle Support Note: Doc ID 1339053.1
Running the command "crsuser add <windows-user>" might be required in your environment for the Action scripts to work. Refer 10.2 for example
10.1. Installation Recommendations
On Windows, the setup should be similar to a UNIX based Oracle RAC configuration. You have to install the Oracle software (Clusterware and Database) as per Oracle best practice.
There is one important difference between UNIX based installations of Dbvisit Standby compared to Windows (when installing on a RAC cluster) and this is that on Windows - Services is used, which means we need to create Dbvnet and Dbvagent services on both nodes in the cluster.
Example steps would be:
- Install the Oracle Clusterware and Configure ASM, including ASM diskgroups and ACFS, shared storage (recommended to place the Dbvisit Software on shared disk - as well as the Dbvisit ARCHDEST/ARCSOURCE locations)
- Install the Oracle Database software (again following best practice from Oracle Documentation).
- Once the database is created - in most cases step 1-3 here would already be done and you would be focussing on the next steps:
- Download the latest Dbvisit Standby software
- Make sure you configure the Virtual IP that will be used by Dbvisit Standby (please see above). This is the IP address/host alias that the standby server will be used to communicate with the RAC cluster - meaning it will see the RAC cluster as one using this Virtual IP (host alias) and from its point of view does not care which node this Virtual IP and of course Dbvisit Standby will be running on.
Example - Below we created a Virtual IP 10.0.2.118 for the VIP Name (host alias) kiwiwin-vip (note this should be added to your DNS). In this example, the RAC cluster was using local accounts and not domain accounts. If domain accounts were used the -user flag should be updated to the domain account.

- Once the Virtual IP is created, you can install Dbvisit Standby on the first node, using shared storage - example if ACFS is used, in this example the shared storage was mounted under C:\app\oracle\acfsmounts\acfs_data
In this example the Dbvisit Base was: C:\app\oracle\acfsmounts\acfs_data\dbvisit
ONLY Dbvnet, Dbvagent and Standby Core components are installed. It is not recommended to run the GUI (Central Console) from a RAC Cluster - but rather on a standalone small system or the standby server.
- Install Dbvisit Standby first on node 1, then on node 2, in both cases install it into the same directory as mentioned above and let the services be created, but after installation makes sure you stop all services.
Also, make sure that when you install Dbvnet and the Agent that you configure the listening address as the Virtual IP hostname. This is to ensure that when Dbvnet or the Agent is started, it will listen on this Virtual IP.
- Now create a directory on both systems, example c:\dbv-scripts
- Inside this directory create two batch scripts which will be used as the Action Scripts when the cluster resources are created.
Example Action Scripts - Please note these are samples and should be tested in your development or test environments prior to implementing into production:

Once these scripts are on both RAC nodes in the exact same location, we can register the resource from the first node (Where the Dbvisit Virtual IP that will be used is running).
The commands to add the cluster resource is shown below:
Example: Add Dbvnet Cluster Resource
C:\dbv-scripts>set ORACLE_HOME=c:\app\11.2.0\grid C:\dbv-scripts>C:\app\11.2.0\grid\bin\crsctl add resource dbvnet -type cluster_resource -attr "ACTION_SCRIPT=c:\dbv-scripts\dbvnet.cmd, RESTART_ATTEMPTS=3, START_TIMEOUT=60, STOP_TIMEOUT=60, CHECK_INTERVAL=10, START_DEPENDENCIES='hard(kiwiwin-vip) pullup(kiwiwin-vip)',STOP_DEPENDENCIES='hard(kiwiwin-vip)' PLACEMENT='favored' HOSTING_MEMBERS='kiwiwin01'"
Example: Add Dbvagent Cluster Resource
C:\dbv-scripts>set ORACLE_HOME=c:\app\11.2.0\grid C:\dbv-scripts>%ORACLE_HOME%\bin\crsctl add resource dbvagent -type cluster_resource -attr "ACTION_SCRIPT=c:\dbv-scripts\dbvagent.cmd, RESTART_ATTEMPTS=3, START_TIMEOUT=60, STOP_TIMEOUT=60, CHECK_INTERVAL=10, START_DEPENDENCIES='hard(kiwiwin-vip) pullup(kiwiwin-vip)',STOP_DEPENDENCIES='hard(kiwiwin-vip)' PLACEMENT='favored' HOSTING_MEMBERS='kiwiwin01'"
