Hi Ron,
I have used ora2pg for a small database, but we have limitation of zero downtime, how do we replicate real time data from Oracle to PostgreSQL. We can migrate schema from Oracle to PostgreSQL using ora2pg and single time bulk data but what about the changed data after bulk load?

Subject: Re: Oracle to PostgreSQL Migration
Real-time CDC is the difficult part. ora2pg (using views) can do a static migration. No coding (unless you consider clever use of bash to modify config files to be coding). I used it to migrate a 7TB db to Postgresql.
Hi,
Hope everyone is fine.
Can someone help or guide regarding Open Source tools for Oracle to PostgreSQL migration with real time CDC. along with this is there any possibility to change the structure of the database? Let me explain a little more,
We have an Oracle DB which is around 1TB and we want to migrate to PostgreSQL that have a new table structure, so we want to perform data transformation and real time CDC from Oracle to PostgreSQL. Do we have any good open source tool to achieve this with No Coding involved.??
Thanks.
