When using MS SQL Server, the following initial database configuration is recommended. However, On this page we state the minimum requirements for a SQL Server installation to support PhixFlow, and present a suggested installation.
The suggested installation incorporates the minimum requirements for SQL Server. It is suitable as an initial configuration for many instances of PhixFlow, but note that some of the options below may need to change over time as the work carried out by PhixFlow increases.

The following the minimum requirements for a SQL Server installation to support PhixFlow.
Server settings
Option | Setting |
SQL Server Edition | Standard or Enterprise |
Version | |
Collation Character set | Latin1_General_100_CI_AI_SC_ |
UTF8 The database that PhixFlow runs against must be created with the collation set to this character set (see Install the PhixFlow Database Schema), otherwise the performance of PhixFlow can be severely impacted. However, PhixFlow uses TEMP tables for efficient processing of ‘is in’ filter clauses with large numbers of parameters, and this uses the collation setting of the server itself. Therefore, it is strongly recommended that the server is set to use this collation. |
Database settings
Parameter | Setting |
Collation | Latin1_General_100_CI_AI_SC_ |
UTF8 | |
READ_COMMITTED_SNAPSHOT | ON |
Login and user
A command to create the database, along with a local (SQL Server) login, and associated user and user mapping, are provided in Install the PhixFlow Database Schema. If you do not wish to use this command, please consult PhixFlow Support.

The following configuration is suggested as a guide. It incorporates the minimum requirements for SQL Server databases above.
