Please select from the following articles to review important considerations:

The Application Server specifications outlined in this article are based on these server types:

  • Production Server: a live environment where created processes are leveraged by end-users (customers) 
  • Non-Production Server: non-customer facing environment used for testing and development to assess production readiness
  • Repository Server: non-customer facing environment used to help maintain version control and migrate projects between servers

Browser Compatibility

Browsers not accounted for in the below chart will support the Portal, but not the Studio.

Hardware Specifications

Consult expertise ahead of server deployment. The deploying organizations' Senior Database Administrator (DBA) should be involved in recommending resources.

Advanced specifications consider the following circumstances:

  • Data-heavy environments
  • Organizations with long procurement/change request cycles

For optimal performance of a Decisions server, it is advisable to configure the server with at least 4 cores and 16 GB of RAM.

Software Requirements

SSL Certificates
While not required for a successful install, SSL certificates are recommended for enhanced HTTP2 support and product performance. Self-signed certificates are accepted.
Operating System.NET CoreHosting Type
Windows Server 2016 - 2019 or newer, 64-bit.NET Core 6.x x64Self-Hosting Considerations

.NET Core 6.x SDK*IIS Hosting Considerations

* = The .NET Core 6.0 SDK is only required for creating Internal and External Webservice References. It is not required to run Decisions.

Database Server and Configuration

Repositories must match the back-end of their connected Server
For example, an SQLApplication Server wishing to use a Repository must connect to one that also uses SQL.  See Installing and Configuring Designer Repository for more information.
Database Server TypeServer Version RequiredAdditional Information
SQLSQL Server 2012 SPI Standard or newer
  • All versions and patches of SQL Server 2019 are compatible with Decisions. This includes both Standard, Enterprise, and Express editions.
  • Standard installation with default collation (SQL_Latin1_General_CP1_CI_AS).
  • Instances may be named; the Instance Name does not need to remain its default value.

Note:  SQL Express should ONLY be used for dev. Environment, as it has a 10 GB limit. DB specs should scale with the use case, hence it is recommended to use a server with 4 cores and 16 Gb RAM for base production instance with Decisions+SQLServer on the same machine.

AzureAll supported

DB level of at least S3 or P1 is recommended to prevent timeouts for Decisions SQL queries, especially during installation.


DB level T3 is recommended for installation.

PostgresPostgres 12 or 13Is supported by all the installer versions.
Postgres 14 or 15Is only supported by installer version 8.10 and above.

It is recommended that Microsoft’s standard SQL maintenance plan is utilized for database maintenance.

Network Ports and Protocols

Depending on the chosen database server, Decisions uses the following default SQL port numbers to connect to the database server.

Database Server TypeSQL Port

To modify the SQL port number, update the connection string syntax (myPortNumber) as follows:

Server=myServerName,myPortNumber;Database=myDataBase;User Id=myUsername;Password=myPassword;

When installing locally, Decisions attempts to occupy the following default ports for users to host its service.

These port numbers may be configured during and after installation.

80Assigned for HTTP connections
443Assigned for HTTPS connections

It is recommended to run Decisions via HTTPS for added security. Refer to the Securing a Decisions Installation for additional security methods.
