Why Dbvisit Standby is Essential for Your Data Protection Strategy

Step-by-Step Setup of Dbvisit Standby for Oracle DatabasesDbvisit Standby is a powerful tool designed to create a high-availability and disaster recovery solution for Oracle databases. This guide will walk you through the process of setting up Dbvisit Standby step by step, ensuring that you can replicate your databases effectively and securely.

Prerequisites

Before diving into the setup, make sure you have:

• Oracle Database Installed: Ensure that your primary database is running Oracle.
• Dbvisit Standby Software: Download the latest version of Dbvisit Standby from the official website.
• Two Servers: You need a primary server where your database is hosted and a standby server where the replicated database will reside.
• Network Connectivity: Both servers should communicate over a network.

Step 1: Install Dbvisit Standby

1. Download the Software: Go to the Dbvisit website and download the appropriate version for your operating system.
2. Extract the Files: Unpack the downloaded zip file to a designated location on both the primary and standby servers.
3. Run the Installation Script:
   • Navigate to the extracted directory in your command-line interface.
   • Execute the installation script using the command:

     
     ./install.sh 

4. Follow On-Screen Instructions: The installation wizard will guide you through configuration options. Make sure to input the correct paths to your Oracle installation during this process.

Step 2: Configure the Primary Database

1. Set Up Archive Logging: Ensure that your Oracle database is in archive log mode:

   ALTER DATABASE ARCHIVELOG; 

2. Configure Initialization Parameters: Modify the database parameters as follows:

   ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=/path/to/archive' SCOPE=SPFILE; ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE; 

   After making changes, restart the database:

   SHUTDOWN IMMEDIATE; STARTUP; 

3. Create a User for Dbvisit:

   CREATE USER dbvisit IDENTIFIED BY password; GRANT CONNECT, RESOURCE, DBA TO dbvisit; 

4. Define the Dbvisit Environment: Navigate to the Dbvisit installation directory and execute:

   dbvisit define_db –db_user=dbvisit 

Step 3: Configure the Standby Database

1. Create a Standby Database: Use either RMAN or Data Pump to clone the primary database onto the standby server. This involves creating an instance and copying over the data files, control files, and redo logs.

2. Set Up Initialization Parameters for Standby: In the init.ora file on the standby server, ensure the following parameters are set:

   LOG_ARCHIVE_DEST_1='LOCATION=/path/to/archive' LOG_ARCHIVE_DEST_2='SERVICE=primary_db' 

3. Set Up Dbvisit Standby on the Standby Server: Navigate to the Dbvisit installation directory on the standby server and run:

   dbvisit define_standby –primary_db=primary_db_name 

Step 4: Configure the Replication Process

1. Create the Replication Configuration: On the primary server, execute the following command to begin the setup of the replication process:

   dbvisit setup 

2. Start the Replication Process: To initiate the transfer of redo logs from the primary to the standby server, use:

   dbvisit start 

3. Monitor the Status: You can check the status of the replication using:

   dbvisit status 

Step 5: Perform a Failover Test

1. Perform a Controlled Failover: To test the configuration and ensure everything is set up correctly, perform a failover procedure:

   • Stop the primary database gracefully.
   • Activate the standby database.

     
     dbvisit failover 

2. Verify Data Integrity: Once the failover is complete, verify that the data on the standby server is intact and accessible.
