Geodatabases in PostgreSQL included with ArcGIS Server for Amazon Web Services
If you use the ArcGIS for Server (Ubuntu Linux) Amazon Machine Image (AMI) to create an ArcGIS Server site, you have the option to include a PostgreSQL database cluster. The database cluster can be on the ArcGIS for Server instance or on a separate instance that is part of your ArcGIS for Server site.
The database cluster contains two pre-created geodatabases: egdb and geodata.
The egdb geodatabase is registered as an ArcGIS Server managed database. When you publish feature or WFS-T services to a site that has a registered managed database, the data can be copied from the geodatabase that contains the map source data (publisher geodatabase) to the registered database (server geodatabase). This data is dependent on the service; when you delete the feature or WFS-T service, the data is deleted from the egdb geodatabase.
The geodata geodatabase is intended for use as a replicated geodatabase. You can register the geodata geodatabase with ArcGIS Server. When you do so, designate the geodata geodatabase as a server database connection that is not the same as your publisher database connection (your on-premises enterprise geodatabase) and create a geodata service. You can replicate data from your on-premises enterprise geodatabase to the geodata geodatabase through the geodata service.
When you publish a feature or WFS-T service that includes the replicated data, edits made to the data through the feature service can be synchronized with the geodata service, updating the data in your on-premises enterprise geodatabase. Similarly, you can continue to edit your on-premises data and use the geodata service to synchronize those changes to the data in the geodata geodatabase.
The PostgreSQL database cluster also contains three database login roles:
- postgres: The database cluster administrator
- sde: The geodatabase administrator
- owner: A user who owns a schema in the egdb and geodata databases and, therefore, can create data in them
By default, the passwords for these users are as follows:
- postgres = postgres
- sde = E$ri3774
- owner = owner
To secure your site, you must log in to the instance that contains the PostgreSQL database cluster and change the passwords. See Changing the passwords of the default PostgreSQL login roles for instructions.
