Convert PostgreSQL to Oracle.

Our DBConvert and DBSync applications support migrations and synchronizations of databases from PostgreSQL to Oracle Server. Direct connections to source and destination are used for quick, reliable connection. Or Dump files may be set up as a target if there is no direct access to a target server. Furthermore, PostgreSQL databases may be located in Amazon RDS or Heroku clouds.

Transfer the whole database or only single elements you choose, using our migration software. Schema and view conversions can be performed easily as well.

Using an easy-to-use wizard interface, our applications guide you through all of the necessary steps needed to successfully migrate your databases. You can also configure conversions and synchronizations to your particular needs by specifying the rules for copying data to a target database. The software supports our powerful command line mode which helps users to automate data transfers.

Our DBConvert and DBSync software converts data types between PostgreSQL and Oracle automatically. But you still have an opportunity to change data types by hand with the help of our smart mapping feature.

Our built-in scheduler helps to run conversions and synchronizations automatically. Furthermore, our trigger-based database synchronizations and three sync types help you to keep your data up-to-date.

Using PostgreSQL to Oracle 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 PostgreSQL source database.

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

Connect to PostgreSQL source database from DBConvert

2. Connect to Oracle 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.

Connect to Oracle target database from DBConvert

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:

  • PostgreSQL to Oracle
  • Oracle to PostgreSQL
  • PostgreSQL to PostgreSQL
  • Oracle to Oracle

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 Oracle 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 PostgreSQL to Oracle.

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 PostgreSQL database to the closest equivalent of the target Oracle 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 PostgreSQL to Oracle

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.

Read more about execution stage available options.

Command line mode

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

Example: C:\Program Files\DBConvert\oracle2postgresqlPro\oracle2postgresqlPro_Cons.exe /Session:"Session_Name"

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

Built-in scheduler.

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