PostgreSQL is a powerful, open source object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.

PostgreSQL is the now the default database technology for OWS

No configuration changes are required to use PostgreSQL

Update database version

All database updates are applied by default now. If you need to update an existing database, the update scripts are in the ./Databases/Postgres/UpdateScripts folder.

Warning! If you already have PostgreSQL installed on your development PC running on port 5432, then OWS 2 will not work

Please adjust the OWS 2 configuration to run PostgreSQL on an alternate port. Here is an example of what to change to switch OWS copy of PostgreSQL to port 15432:

  1. Open the .env file and go to the Postgres connection string and edit it like this:
    # Postgres
  2. Open databases.yml and edit it like this: ```

    PostgreSQL Database

    postgres: build: context: postgres/ environment:

    • “15432:5432” volumes:
    • database:/var/lib/postgresql/data container_name: PostgreSQL ``` Notice that we ONLY change the first number to 15432 and not the second number. The second number has to stay 5432.

Create API Key

  1. Open PGAdmin3/4 or dBeaver and connect to localhost using the following credentials:

  2. Run the following SQL statment against the Open World Server database.

    (Optional): Replace NULL with a single-quoted UUID. For example ‘00000000-0000-0000-0000-000000000000’::uuid

     CALL AddNewCustomer ('CustomerName', 'FirstName', 'LastName', 'Email', 'Password', NULL);

    Be sure to replace the values:

    The nickname or profile name of the customer.
    The firstname of the customer.
    The lastname of the customer.
    Enter the mail address of the customer.
    Enter a secure password.
  3. Run the following SQL statment against the Open World Server database to get your API key. Save the key for later.

    SELECT CustomerGUID FROM Customers LIMIT 1;

    The above query only works if this is a new OWS 2 installation. A common issue during setup is when you have more than one API key (CustomerGUID).
