• Memory (RAM): At least 8 GB of RAM is required. For environments with high data volumes or complex transformations, 16 GB or more is advised.
• Disk Space: Sufficient disk space is crucial for storing the captured data and logs. A minimum of 100 GB is recommended, with additional space depending on the volume of data and the retention period.
• Network: A stable and high-speed network connection is essential for real-time data capture and replication. The network bandwidth should be proportional to the data throughput requirements of your deployment.

3. Software Requirements
IBM CDC 11.4 integrates with various operating systems, databases, and other software components. The following software requirements are essential:

• Operating System: CDC 11.4 supports various operating systems including Windows Server 2016 and 2019, as well as Linux distributions such as Red Hat Enterprise Linux (RHEL) 7 and 8, and SUSE Linux Enterprise Server (SLES) 12 and 15. Ensure that the operating system is up-to-date with the latest patches and service packs.
• Database: Compatible databases include IBM Db2, Oracle, Microsoft SQL Server, and others. Ensure that the database version is supported by CDC 11.4. Check IBM's compatibility matrix for detailed information.
• Java: IBM CDC 11.4 requires Java Runtime Environment (JRE) 8 or higher. Ensure that the correct version of JRE is installed and configured on the server.
• Middleware: Depending on the deployment scenario, additional middleware components such as message brokers or application servers may be required. Ensure compatibility with CDC 11.4.

4. Configuration Requirements
Proper configuration is critical to ensure that IBM CDC 11.4 operates efficiently. Here are some configuration considerations:

• Network Configuration: Configure network settings to allow CDC 11.4 to communicate with source and target systems. This may involve configuring firewalls, proxies, and other network devices to permit the necessary traffic.
• Database Configuration: Ensure that the source and target databases are configured to support CDC operations. This may involve setting up database replication settings, permissions, and schemas.
• CDC Parameters: Configure CDC-specific parameters such as capture and apply settings, logging options, and performance tuning parameters based on the deployment's requirements.

5. Security Requirements
Security is a critical aspect of any data integration solution. For IBM CDC 11.4, consider the following security requirements:

• Access Control: Implement role-based access control to ensure that only authorized personnel can access and configure CDC 11.4.
• Encryption: Use encryption to protect data in transit and at rest. Ensure that encryption settings are configured for both source and target systems.
• Auditing: Enable auditing to monitor and log activities related to data capture and replication. This helps in maintaining compliance and troubleshooting issues.

6. Performance and Scalability Considerations
IBM CDC 11.4 is designed to handle large volumes of data and high transaction rates. To ensure optimal performance and scalability:

• Resource Allocation: Allocate sufficient resources based on the anticipated data volume and transaction rate. Monitor resource usage and adjust as needed.
• Load Balancing: Implement load balancing to distribute workloads across multiple CDC instances or servers. This can help in managing high data throughput and ensuring high availability.
• Tuning: Regularly review and tune performance settings based on usage patterns and performance metrics.

7. Troubleshooting and Support
Having a plan for troubleshooting and support is crucial for maintaining the health of your CDC 11.4 deployment:

• Monitoring: Use monitoring tools to track the performance and health of CDC 11.4. Set up alerts for critical issues that may impact the system.
• Support: Familiarize yourself with IBM's support resources, including documentation, forums, and customer support services. Ensure that you have access to the latest patches and updates.

8. Conclusion
In summary, implementing IBM CDC 11.4 requires careful planning and consideration of various hardware, software, and configuration requirements.
