Convert Oracle to MySQL.

Using Oracle to MySQL conversion and synchronization tools.

When you start DBConvert or DBSync application in GUI mode it guides you through several steps to set up the database migration or synchronization:

1. Connect to Oracle source database.

If a source database requires you to log in, you can specify a user name/ password and host/ port parameters.

2. Connect to MySQL destination database.

Specifying parameters for destination database looks like the same as for source. Usually, it consists of defining connection settings and username/password pairs.

NOTE #1: Every DBConvert or DBSync tool has two different databases in its name. That means any specified database from a pair can be set up as a source or destination. Besides, the same type of database may be set up both as a source or destination.

As an example, here is the list of possible migration directions with on-premises databases:

• Oracle to MySQL
• MySQL to Oracle
• Oracle to Oracle
• MySQL to MySQL

NOTE #2: Don't be confused by the fact that connections to cloud databases like Amazon RDS, Microsoft Azure SQL, Google Cloud, and Heroku are not explicitly specified in the configuration of a source or destination in the DBConvert / DBSync interface. To connect to Cloud database instances, use the same settings as you do for traditional on-premises databases.

NOTE #3: Your connections to source and target databases stay active until you close DBConvert/ DBSync application or reopen new connections on "source" and "destination" steps.

Read more about the specific source/ destination configurations for different databases.

3. Custoimzation and configuration.

At the next step, you can specify precisely which tables, fields, indices, views you want to transfer to the MySQL destination database. Just check/ uncheck the box in front of each database object you want to convert.

Customize general database/ tables settings. Or set up a particular table , field, index individually when migrating data from Oracle to MySQL.

Check out our articles about Custoimzation and configuration. for detailed information.

The screenshot below sums up general features available in DBConvert software solutions.

4. Detection of potential database migration issues. Errors and Warnings

The database typically constrains certain relations on the data that cannot be violated. On the customization step, a smart error checker verifies all possible Data integrity and Referential integrity issues and highlights them, if any, before performing a migration.

DBConvert software to default tries to automatically map database types from the source Oracle database to the closest equivalent of the target MySQL database types. But you can manually change data types for the whole database globally with "Global mapping" or individually for each field.

Check out Smart error checker. Errors and Warnings for more information.

5. Execution. The final stage of data migration from Oracle to MySQL

Once you configure source and destination databases for migration in the previous steps, you can start the actual conversion or synchronization process.

Click the "Commit" button to start conversion. Also, here, you can monitor the migtation/ synchronization process.

Optionally save connection settings and configuration parameters into the session file to schedule the launching of sync or migration jobs regularly.

Command line mode

Previously saved sessions can be passed as parameters to Command-Line DBConvert Client. A session keeps Oracle source and MySQL target database connection settings with other specified options.

Example: C:\Program Files\DBConvert\oracle2mysqlPro\oracle2mysqlPro_Cons.exe /Session:"Session_Name"

NOTE: First, you have to run the software in GUI mode to create a session file with initial parameters.
