migrating an oracle database to postgresql on amazon web services (aws) can be a complex process, but it can be simplified by using aws services and tools designed for database migration. below is a comprehensive tutorial that outlines the steps involved in this migration process, along with code examples.

prerequisites

1. **aws account**: you need an active aws account.
2. **oracle database**: ensure you have access to the oracle database that you want to migrate.
3. **postgresql database**: set up a postgresql database in aws (e.g., using amazon rds).
4. **aws schema conversion tool (sct)**: this tool helps convert the oracle schema to postgresql-compatible schema.
5. **aws database migration service (dms)**: this service facilitates the actual data migration.

step-by-step migration process

step 1: set up your postgresql database

1. **create a postgresql database instance on rds**:
go to the aws rds console.
choose "create database".
select "postgresql" as the engine.
configure instance specifications (db instance class, storage, etc.).
set the database identifier, username, and password.
launch the instance.

2. *configure security groups* to allow access to the postgresql instance from your ip or your application.

step 2: install and configure aws schema conversion tool (sct)

1. *download the aws sct* from the [aws sct website](https://aws.amazon.com/dms/schema-con....
2. *install the sct* on your local machine or an ec2 instance.
3. **connect to oracle database**:
open aws sct.
create a new project and connect to your oracle database using the oracle jdbc connection details.

4. **connect to postgresql database**:
add a target database connection for your postgresql instance.

5. **convert schema**:
select the oracle schema you want to migrate.
right-click and choose "convert schema".
review the conversion report for any issues and make necessary adjustments.

6. **generate ...
