SQL Server to Oracle conversion and synchronization.

Our DBConvert/ DBSync solutions will convert and synchronize your SQL databases and Oracle databases.

These applications quickly move your data from MS SQL server/ Windows Azure SQL databases to Oracle server and conversely.

Our software reduces the risk of data migration loss by employing a secure and reliable migration methodology. Applications give preemptive messages about possible conversion and synchronization errors before starting the actual execution process. In just a ew easy steps your database migration project will be successfully completed.

You can customize all conversion and synchronization processes, adjusting the tools to your specific requirements. Data export and import may be full or partial. The tools allow moving not only the entire database but also the separate elements including tables, fields, primary keys, primary constraints and indexes.

Conversion to Dump files, in addition to direct conversion to a target server, is supported in the DBConvert tool.

DBSync for MSSQL and Oracle reliably and rapidly synchronizes your database from MS SQL Server or Windows Azure SQL databases to Oracle servers and conversely.

DBSync has insert, update and drop synchronization. Boost your database synchronizations using our trigger-based sync feature and you’ll notice that the processing speed is much faster.

Our applications support automatic job launching with the help of our built-in scheduler. They also support command line operation.

Different types of synchronization are also available for keeping your databases up-to-date.

Using SQL Server to Oracle conversion and synchronization tools.

When launching the DBConvert or DBSync application in GUI mode, it seamlessly guides you through the steps to initiate database migration or synchronization:

1. Connect to SQL Server source database.

Specify the username/password and host/port parameters if your source database requires login credentials.

Connect to SQL Server source database from DBConvert

2. Connect to Oracle destination database.

Specify parameters for the destination database similar to the source, defining connection settings and username/password pairs.

Connect to Oracle target database from DBConvert

NOTE #1: Each DBConvert or DBSync tool's name comprises two different databases, enabling any specified database to operate as the source or destination. Furthermore, the same type of database can function as both the source and destination.

NOTE #2: Connections to cloud databases (e.g., Amazon RDS, Google Cloud, or Azure SQL) aren't explicitly specified in the user interface but use the same settings as traditional on-premises databases.

NOTE #3: Connections to source and target databases remain active until you close the DBConvert/DBSync application or reopen new connections.

Refer to our documentation for specific source/ destination configurations for different databases.

3. Configure database migration options.

Specify the tables, fields, indices, and views you want to transfer to the Oracle destination database by checking/unchecking the corresponding boxes.

Customize general database/ tables settings. Or configure specific table , field, index object individually when migrating data.

Explore our articles in the user's manual about Configuring database migration options. for detailed information.

The screenshot below summarizes the general features available in DBConvert software.

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

The database enforces certain relations on the data, and on the customization step, an intelligent error checker verifies all possible data integrity and referential integrity issues. It highlights any problems before migration starts.

By default, DBConvert attempts to automatically map the database types of the source SQL Server database to the closest equivalent of the target Oracle database types. However, you can manually change the data types for the entire database globally using the "Global mapping" or individually for each field.

Explore the Intelligent error checker for more information. on errors and warnings

5. Execution. The final stage of data migration.

Initiate the conversion or synchronization process after configuring source and destination databases in the previous steps.

Click the "Commit" button to start conversion. Here, you can also monitor the migration/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

Pass previously saved sessions as parameters to the Command-Line DBConvert Client. A session retains SQL Server source and Oracle target database connection settings with other specified options.


C:\Program Files\DBConvert\oracle2mssqlPro\oracle2mssqlPro_Cons.exe /Session:"Session_Name"

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

Built-in scheduler.

Our applications include a built-in scheduler to run database migration and sync jobs at specified times. Set the scheduled date and time to execute job sessions automatically.
