Using DMS CDC for Oracle to Postgres

Question

Hello All,

I am trying to see the feasibility of using DMS CDC for Oracle to Postgres on going data updates. Created the task for CDC. It is reading changes from the Oracle 19c Source table. For some unknown reason(for myself), it is not applying the changes to Postgres 13 RDS database.

Is there a specific setup i am missing? Please advice.

Thanks in Advance

Answer

Can you confirm you have followed these steps to set-up the source Oracle database - https://docs.aws.amazon.com/dms/latest/sbs/chap-on-premoracle2aurora.steps.configureoracle.html

Answer

Thank you for your response.

Yes. I did all the settings as in the document. It was working fine for Oracle to Oracle RDS data replication.

Now trying to do the same for Oracle to Postgres RDS.

I am sure it is some privilege missing on the target instance. Not sure, what it is.

Answer

Hello,

As DMS task worked fine with Oracle to Oracle RDS data replication, the difference between Postgres would come for tables names. Oracle treat all table name  in CAPITAL letter but postgres is the opposite, all in LOWERCASE.
Most likely you would need to add transformation rule to convert all table and schema name to lower case.

Hope that helps, if not, then pls. share the dms log for understanding it more.

Thanks
