How to Use RBA in Oracle Golden Gate A Comprehensive Guide

In this article, we will explore the use of RBA (Remote Buffer Access) in Oracle Golden Gate for real-time replication. We will cover the step-by-step process of performing an initial load from the source to the target, creating an extract pump, and replicating a particular table. It is important to note that these activities are performed in a schema environment.

Key Points:
– Checking the status of the source and target servers
– Creating a new user and granting privileges
– Creating a table and inserting data into it
– Performing an initial load from the source to the target
– Starting the extract, pump, and replicate processes
– Monitoring the RBA count to ensure data replication

Step 1: Checking Server Status

Before starting the replication process, it is essential to ensure that both the source and target servers are running smoothly. Check the status of the source server by verifying if the database is running properly. Similarly, check the listener services on both the source and target servers.

Step 2: Creating a New User and Granting Privileges

Next, create a new user in the database. It is important to note that in a real-time scenario, creating a user with DBA privileges is not recommended. However, for the purpose of this demonstration, DBA privileges will be granted to the user. Connect to the database and execute the necessary queries to create the user and grant the privileges.

Step 3: Creating a Table and Inserting Data

Now, create a new table within the user/schema. Grant the necessary privileges and security settings to the table. Insert a substantial amount of data into the table for replication purposes. Verify the count of the table to ensure data insertion.

Step 4: Performing Initial Load from Source to Target

On the target side, create the same user and connect to the database using the user credentials. Ensure that no data is present in the table at this stage. Perform the initial load from the source to the target by starting the load process. This process involves specifying the source and target details, such as IP address and port number. Once the load is complete, the process will stop automatically.

Step 5: Starting Extract, Pump, and Replicate Processes

To enable real-time replication, start the extract, pump, and replicate processes. These processes are crucial in pulling and pushing data from the source to the target. Specify the extract process details, including the Oracle home location and password. Similarly, configure the pump process with the necessary parameters. Finally, define the replicate process, which will specify the schema and table to be replicated.

Step 6: Monitoring RBA Count for Data Replication

It is important to monitor the Remote Buffer Access (RBA) count to ensure that data is being replicated successfully. The RBA count represents the amount of data replicated from the source to the target. Insert additional data into the table and verify that the RBA count is increasing accordingly. This step confirms that the extract, pump, and replicate processes are configured correctly.

In summary, using RBA in Oracle Golden Gate for real-time replication involves ensuring the proper functioning of the source and target servers, creating a new user, performing an initial load from the source to the target, starting the extract, pump, and replicate processes, and monitoring the RBA count for data replication.

By following these steps, organizations can effectively replicate data in real-time using Oracle Golden Gate with the assurance of data integrity and consistency. Golden Gate provides various customization options, allowing users to replicate specific tables or columns according to their requirements.
