Thread: Strategy for migrating from Oracle to PG

Strategy for migrating from Oracle to PG

From
"Johnson, Bruce E - (bjohnson)"
Date:
I have an oracle database with a bunch of schemas that are the data sources for bunch of web applications; what used to be called an ‘intranet’.

I’ve installed pg2sql, and it’s working, and what I want to do is pretty much copy what I existing now as closely as possible.

I've done ora2pg —project_base /oracle_migrate/ —init_project [schema name]

Properly set the schema username and password in the ./config/ora2pg.conf filer each of them

Do I need to create the users in Postgres, or is that done as part of the import_all.sh script?

The schemas themselves are not all that complex, mostly just tables, views and a handful of procedures and grants. 

Installed version of Postgres is v15.

As far as I know, you don't need to create the users, if you create the user anyway before migration then ora2pg will skip the create statement, but objects under the user/schema will be created
