Preparing a database for installation of Amplia

In order to install a on-premises installation of Amplia, you will need a connection string for one of the following database engines:

SQL Server

To use SQL Server, you will need a database having:

  • Collation: Latin1_General_100_CI_AI or Latin1_General_CI_AI
  • Credentials corresponding to a user with db_owner role
Note

If you prefer to run Amplia without granting db_owner to the application user, see this article

Warning

The collation of the database must be one of the collations specified above. Creating the database with a different collation will likely cause the installation to fail!

If you need help preparing the database, follow the steps in this article.

Note

You do not need to follow these specific instructions. If you wish to prepare the database differently, for instance using advanced features such as log shipping or mirroring, you may do so, as long as the collation and role memberships are observed.

To create the database, use the following T-SQL query (optionally changing the database name):

USE master;
CREATE DATABASE Amplia COLLATE Latin1_General_100_CI_AI;
GO

Create a user and grant it the db_owner role:

USE master;
CREATE LOGIN AmpliaAdm WITH PASSWORD = 'XXXXX';
GO

USE Amplia;
CREATE USER AmpliaAdm FOR LOGIN AmpliaAdm;
EXEC sp_addrolemember 'db_owner', 'AmpliaAdm';
GO

The connection string would then be:

Data Source=.;Initial Catalog=Amplia;User ID=AmpliaAdm;Password=XXXXX
Note

This connection string assumes the database server is installed on the same server as the web app. If this is not true, the value after Data Source= would have to be changed.

PostgreSQL

Starting on version 4.1.0 of Amplia, PostgreSQL is also supported. Any version currently supported of PostgreSQL is also supported (which at the moment means version 11 or greater).

Start by creating the database and a user for the application (optionally changing the names of the database and user):

postgres=# CREATE DATABASE amplia;
CREATE DATABASE
postgres=# CREATE USER amplia WITH PASSWORD 'XXXXX';
CREATE ROLE

Next, connect to the newly created database and set the permissions for the public schema:

postgres=# \connect amplia
You are now connected to database "amplia" as user "postgres".
amplia=# REVOKE ALL ON SCHEMA public FROM PUBLIC;
REVOKE
amplia=# GRANT ALL ON SCHEMA public TO amplia;
GRANT
amplia=# CREATE SCHEMA hangfire;
CREATE
amplia=# GRANT ALL ON SCHEMA hangfire TO amplia;
GRANT
Note

For now, only using a user with full schema access is supported. Please contact us if you need to run Amplia with less privileges.

The connection string would then be (assuming you didn't change the database and user names):

Host=localhost;Database=amplia;Username=amplia;Password=XXXXX
Note

This connection string assumes the database server is installed on the same server as the web app. If this is not true, the value after Host= would have to be changed.
