TL;DR

This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:

1. set up IBM Db2 as a source connector (using Auth, or usually an API key)
2. set up MySQL as a destination connector
3. define which data you want to transfer and how frequently

You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

This tutorial’s purpose is to show you how.

What is IBM Db2

Specializing in the development and maintenance of Android, iOS, and Web applications, DB2’s AI technology offers fast insights, flexible data management, and secure data movement to businesses globally through its IBM Cloud Pak for Data platform. Companies rely on DB2’s AI-powered insights and secure platform and save money with its multimodal capability, which eliminates the need for unnecessary replication and migration of data. Additionally, DB2 is convenient and will run on any cloud vendor.

What is MySQL

MySQL is an SQL (Structured Query Language)-based open-source database management system. An application with many uses, it offers a variety of products, from free MySQL downloads of the most recent iteration to support packages with full service support at the enterprise level. The MySQL platform, while most often used as a web database, also supports e-commerce and data warehousing applications, and more.

Prerequisites

1. A IBM Db2 account to transfer your customer data automatically from.
2. A MySQL account.
3. An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.

Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including IBM Db2 and MySQL, for seamless data migration.

When using Airbyte to move data from IBM Db2 to MySQL, it extracts data from IBM Db2 using the source connector, converts it into a format MySQL can ingest using the provided schema, and then loads it into MySQL via the destination connector. This allows businesses to leverage their IBM Db2 data for advanced analytics and insights within MySQL, simplifying the ETL process and saving significant time and resources.

Methods to Move Data From IBM db2 to mysql

• Method 1: Connecting IBM db2 to mysql using Airbyte.
• Method 2: Connecting IBM db2 to mysql manually.

10. Congratulations! You have successfully connected your MySQL destination connector on Airbyte and can now start syncing data from your source to your MySQL database.

Step 3: Set up a connection to sync your IBM Db2 data to MySQL

Once you've successfully connected IBM Db2 as a data source and MySQL as a destination in Airbyte, you can set up a data pipeline between them with the following steps:

1. Create a new connection: On the Airbyte dashboard, navigate to the 'Connections' tab and click the '+ New Connection' button.
2. Choose your source: Select IBM Db2 from the dropdown list of your configured sources.
3. Select your destination: Choose MySQL from the dropdown list of your configured destinations.
4. Configure your sync: Define the frequency of your data syncs based on your business needs. Airbyte allows both manual and automatic scheduling for your data refreshes.
5. Select the data to sync: Choose the specific IBM Db2 objects you want to import data from towards MySQL. You can sync all data or select specific tables and fields.
6. Select the sync mode for your streams: Choose between full refreshes or incremental syncs (with deduplication if you want), and this for all streams or at the stream level. Incremental is only available for streams that have a primary cursor.
7. Test your connection: Click the 'Test Connection' button to make sure that your setup works. If the connection test is successful, save your configuration.
8. Start the sync: If the test passes, click 'Set Up Connection'. Airbyte will start moving data from IBM Db2 to MySQL according to your settings.

Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your MySQL data warehouse is always up-to-date with your IBM Db2 data.

Migrating data from IBM DB2 to MySQL without using third-party connectors or integrations involves several steps, including data export, data conversion, and data import. Below is a detailed step-by-step guide to accomplish this task:

Method 2: Connecting IBM db2 to mysql manually

Step 1: Prepare the MySQL Database

1. Install MySQL: Ensure that MySQL is installed on the target system. If not, download and install it from the official MySQL website.

2. Create a Database: Log in to MySQL and create a new database where you will import the DB2 data.

   ```

   CREATE DATABASE target_database;

   ```

3. Create Tables: Define the schema in MySQL that matches the DB2 source. Ensure that data types are compatible and consider differences between DB2 and MySQL data types.

   ```

   USE target_database;

   CREATE TABLE example_table (

       column1 INT,

       column2 VARCHAR(255),

       ...

   );

   ```

Step 2: Export Data from IBM DB2

1. Connect to DB2: Use the DB2 command line tool to connect to your DB2 database.

   ```

   db2 connect to source_database user myusername using mypassword

   ```

2. Export Data: Use the `EXPORT` command to export data from the DB2 tables to delimited text files or CSV files.

   ```

   db2 "EXPORT TO '/path_to_exported_file/table_name.csv' OF DEL TYPE MODIFIED BY NOCHARDEL SELECT * FROM schema_name.table_name"

   ```

   Repeat this step for each table you want to migrate.

Step 3: Data Conversion (if necessary)

1. Check Data Types: Review the exported data for any data types that may not be directly compatible with MySQL and convert them accordingly.

2. Date/Time Formats: Convert any date/time values to formats supported by MySQL.

3. Character Encoding: Ensure the character encoding in the exported files matches the encoding expected by MySQL (e.g., UTF-8).

Step 4: Import Data into MySQL

1. Prepare MySQL for Import: Log in to MySQL and select the target database.

   ```

   mysql -u username -p

   USE target_database;

   ```

2. Disable Constraints: Temporarily disable foreign key checks to avoid constraint violations during import.

   ```

   SET FOREIGN_KEY_CHECKS=0;

   ```

3. Import Data: Use the `LOAD DATA INFILE` command to import the data from the CSV files into the corresponding MySQL tables.

   ```

   LOAD DATA INFILE '/path_to_exported_file/table_name.csv'

   INTO TABLE example_table

   FIELDS TERMINATED BY ','

   OPTIONALLY ENCLOSED BY '"'

   LINES TERMINATED BY '\n'

   IGNORE 1 LINES;

   ```

   Adjust field terminators and line terminators according to the format of your exported files. Repeat this step for each table.

4. Re-enable Constraints: Once all data is imported, re-enable foreign key checks.

   ```

   SET FOREIGN_KEY_CHECKS=1;

   ```

Step 5: Verify Data Integrity

1. Check Data Counts: Compare the row counts in MySQL tables with the original DB2 tables to ensure all data was imported.

   ```

   SELECT COUNT(*) FROM example_table;

   ```

2. Check Data Quality: Perform queries on both databases to compare random sets of data and ensure they match.

Step 6: Finalize the Migration

1. Indexing: Create any necessary indexes on the MySQL tables to optimize performance.

2. Optimization: Run `ANALYZE TABLE` on the imported tables to update table statistics for better performance.

   ```

   ANALYZE TABLE example_table;

   ```

3. Backup: Take a backup of the MySQL database after the migration to ensure you have a recovery point.

Step 7: Post-Migration Tasks

1. Update Applications: Change the database connection settings in any applications that need to connect to the new MySQL database.

2. Test: Thoroughly test your applications to ensure they function correctly with the new MySQL database.

3. Monitoring: Monitor the MySQL database for performance and stability issues.

Additional Notes

- The above commands are examples and may need to be adjusted based on your specific environment, table names, schema, data types, and file paths.

- Always perform a migration on a test environment before applying it to production.

- Make sure to have backups of both the DB2 and MySQL databases in case you need to roll back.

- Review MySQL's documentation for any version-specific features or limitations.

By following these steps, you should be able to migrate your data from IBM DB2 to MySQL without using third-party connectors or integrations. Remember to proceed with caution and test thoroughly at each step.

Use Cases to transfer your IBM Db2 data to MySQL

Integrating data from IBM Db2 to MySQL provides several benefits. Here are a few use cases:

1. Advanced Analytics: MySQL’s powerful data processing capabilities enable you to perform complex queries and data analysis on your IBM Db2 data, extracting insights that wouldn't be possible within IBM Db2 alone.
2. Data Consolidation: If you're using multiple other sources along with IBM Db2, syncing to MySQL allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
3. Historical Data Analysis: IBM Db2 has limits on historical data. Syncing data to MySQL allows for long-term data retention and analysis of historical trends over time.
4. Data Security and Compliance: MySQL provides robust data security features. Syncing IBM Db2 data to MySQL ensures your data is secured and allows for advanced data governance and compliance management.
5. Scalability: MySQL can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding IBM Db2 data.
6. Data Science and Machine Learning: By having IBM Db2 data in MySQL, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
7. Reporting and Visualization: While IBM Db2 provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to MySQL, providing more advanced business intelligence options. If you have a IBM Db2 table that needs to be converted to a MySQL table, Airbyte can do that automatically.

Wrapping Up

To summarize, this tutorial has shown you how to:

1. Configure a IBM Db2 account as an Airbyte data source connector.
2. Configure MySQL as a data destination connector.
3. Create an Airbyte data pipeline that will automatically be moving data directly from IBM Db2 to MySQL after you set a schedule

With Airbyte, creating data pipelines take minutes, and the data integration possibilities are endless. Airbyte supports the largest catalog of API tools, databases, and files, among other sources. Airbyte's connectors are open-source, so you can add any custom objects to the connector, or even build a new connector from scratch without any local dev environment or any data engineer within 10 minutes with the no-code connector builder.
