Moving Oracle databases to the cloud isn’t always straightforward. Sometimes, it requires careful planning and analysis. That’s where Oracle’s Cloud Premigration Advisor Tool (CPAT) comes in. It helps analyze your database to ensure a smooth transition.
But running CPAT can be tricky, especially if you’re not familiar with command-line tools. That’s where Cloud Premigration Advisor Tool (CPAT) Composer steps in. It’s a simple, graphical tool that makes it easy to generate CPAT commands.
The CPAT Composer is a user-friendly graphical interface for Oracle CPAT, making it easier to build execution commands with all available options and parameters.
Instead of manually writing complex command-line inputs, users can configure settings through a simple, intuitive interface while previewing the generated CPAT command in real-time.

Key Features of CPAT Composer
- Version Selection: Users can choose from different CPAT versions.
- Template Utilization: CPAT Composer offers various templates, such as “SA: Recommended Settings,” “SA: Custom Settings,” and “SA: Online Migration to BaseDB / ExaDB.” These templates are used for different migration scenarios, providing configurations for each use case.
- Output Preview: Before executing, users can view the generated CPAT command, allowing for verification and adjustments as needed.
Benefits of Using CPAT Composer
- User-Friendly Interface: The graphical nature of CPAT Composer makes it accessible to users with varying levels of technical expertise, reducing the learning curve associated with command-line tools.
- Efficiency: By automating the command generation process, CPAT Composer saves time and minimizes the potential for errors that can occur with manual command-line inputs.
- Customization: The availability of different templates and version selections allows users to adapt the CPAT execution to their specific migration needs, enhancing the accuracy and relevance of the assessment.
