Automated Continuous Oracle SCM Replication to Apache Cassandra
Use CData Sync for automated, continuous, customizable Oracle SCM replication to Apache Cassandra.
Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Oracle SCM data into your Apache Cassandra instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.
Configure Apache Cassandra as a Replication Destination
Using CData Sync, you can replicate Oracle SCM data to Apache Cassandra. To add a replication destination, navigate to the Connections tab.
- Click Add Connection.
- Select the Destinations tab and locate the Cassandra connector.
- Click the Configure Connection icon at the end of that row to open the New Connection page. If the Configure Connection icon is not available, click the Download Connector icon to install the Cassandra connector. For more information about installing new connectors, see Connections in the Help documentation.
- To connect to Apache Cassandra, set the following connection properties:
- Connection Name: Enter a connection name of your choice for the Cassandra connection.
- Server: Enter the host name or the IP address of the server that hosts the Cassandra database. The default host name is localhost.
- Port: Enter the port number of the server that hosts the Cassandra database. The default port value is 9042.
- Database: Enter the name of the Cassandra keyspace that contains your tables.
- Auth Scheme: Select the authentication scheme. The default setting is Basic.
- User: Enter the username that you use to authenticate to the Cassandra database.
- Password: Enter the password that you use to authenticate to the Cassandra database.
- Use SSL: Specify whether you want to use the Secure Sockets Layer (SSL) protocol. The default value is False.
- Consistency Level: Select the number of the replicas from which you want to enforce a response before queries are considered a success.
- Once connected, click Create & Test to create, test and save the connection.
You are now connected to Apache Cassandra and can use it as both a source and a destination.
NOTE: You can use the Label feature to add a label for a source or a destination.
In this article, we will demonstrate how to load Oracle SCM data into Apache Cassandra and utilize it as a destination.
Configure the Oracle SCM Connection
You can configure a connection to Oracle SCM from the Connections tab. To add a connection to your Oracle SCM account, navigate to the Connections tab.
- Click Add Connection.
- Select a source (Oracle SCM).
- Configure the connection properties.
The following connection properties are required to connect to Oracle SCM data.
- Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
- User: The username of your Oracle Cloud service account.
- Password: The password of your Oracle Cloud service account.
- Click Connect to Oracle SCM to ensure that the connection is configured properly.
- Click Save & Test to save the changes.
Configure Replication Queries
CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.
Replicate Entire Tables
To replicate an entire table, navigate to the Task tab in the Job, click Add Tasks, choose the table(s) from the list of Oracle SCM tables you wish to replicate into Apache Cassandra, and click Add Tasks again.
Customize Your Replication
You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication with the help of SQL queries.
Schedule Your Replication
Select the Overview tab in the Job, and click Configure under Schedule. You can schedule a job to run automatically by configuring it to run at specified intervals, ranging from once every 10 minutes to once every month.
Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your Oracle SCM data to Apache Cassandra.
Run the Replication Job
Once all the required configurations are made for the job, select the Oracle SCM table you wish to replicate and click Run. After the replication completes successfully, a notification appears, showing the time taken to run the job and the number of rows replicated.
