Hi @Stephen_Hazlehurst and welcome to MongoDB community forums!!

Based on the information provided, it appears that you are encountering challenges related to syncing an Oracle database with MongoDB. If your intention is to synchronize data between two MongoDB clusters, the recommended approach is to use mongosync. This technique is specifically designed for syncing data within MongoDB clusters.

However, if you are looking to migrate data from Oracle to MongoDB, the ideal tool for this task is the Relational Migrator. This tool streamlines the process of moving data from relational databases, such as Oracle, to MongoDB.

Feel free to reach out if you have any additional concerns or questions. We’re here to assist you!

Warm Regards


Hi, not looking to migrate simply sync from oracle DB to a third party mongo DB, with as near real time as possible.

Hi @Stephen_Hazlehurst

Thank you for getting back.
Unfortunately there is no direct way to sync data between the two databases other than the two provided above. But you can make use of some third party tools available to do so.
A few example would be

Since these tools are not from MongoDB and do not have expertise for the same, we do not guarantee for the authenticity and the correctness of the application.

The recommendation would be to look for the public forums like StackOver Flow and their own public forums to get better assistance.
