A server must meet the following system requirements for installation of a One Identity Manager database. Depending on the number of One Identity Manager modules and the accounts managed in One Identity Manager, the requirements for working memory, hard disk storage, and processors may be significantly greater than the minimum requirements.
Table 3: Minimum system requirements - database server
|
Processor |
8 physical cores with 2.5 GHz+ frequency (non-production)
16 physical cores with 2.5 GHz+ frequency (production)
NOTE: 16 physical cores are recommended on the grounds of performance. |
|
Memory |
16 GB+ RAM (non-production)
64 GB+ RAM (production) |
|
Hard drive storage |
100 GB |
|
Operating system |
Windows operating systems
UNIX and Linux operating systems
|
|
Software |
Following versions are supported:
NOTE: For performance reasons, the use of SQL Server Enterprise Edition is recommended for live systems.
|
NOTE: The minimum requirements listed above are considered to be for general use. With each custom One Identity Manager deployment these values may need to be increased to provide ideal performance. To determine production hardware requirements, it is strongly recommended to consult a qualified One Identity Partner or the One Identity Professional Services team. Failure to do so may result in poor database performance.
For additional hardware recommendations, read the KB article https://support.oneidentity.com/identity-manager/kb/290330/how-to-configure-settings-as-per-the-system-information-overview, which describes the overview of the system information available in One Identity Manager.
NOTE: In virtual environments, you must ensure that the VM host provides performance and resources to the database server according to system requirements. Ideally, resource assignments for the database server are fixed. Furthermore, optimal I/O performance must be provided, in particular for the database server. For more information about virtual environments, see Product Support Policies.

For installation and operation of a One Identity Manager database, the following database server and database settings are required:
Table 4: Database server settings
|
Language |
English |
Select English as the default language for database users. |
|
Server Collation |
Case insensitive
SQL_Latin1_General_CP1_CI_AS (recommended) |
|
|
Extreme transaction processing supported (Is XTP supported) |
True |
One Identity Manager uses In-Memory-OLTP (Online Transactional Processing) for memory-optimized data accesses. The database server must support extreme transaction processing (XTP). This function is activated by default in a default installation.
The setting is tested by the Configuration Wizard before installing or updating One Identity Manager database. If XTP is not activated, the installation or update does not start. |
Table 5: Database settings
|
Collation |
SQL_Latin1_General_CP1_CI_AS |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Recovery model |
Simple |
The setting is tested by the Configuration Wizard before installing or updating One Identity Manager database. If the recovery model is not set to the value Simple, a warning is issued before installing or updating starts. You can ignore this warning.
For performance reasons, however, it is recommended you set the database to the Simple recovery model for the duration of the schema installation or update. |
|
Compatibility level |
SQL Server 2019 (150) |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Auto Create Statistics |
True |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Auto Update Statistics |
True |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Auto Update Statistics Asynchronously |
True |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Arithmetic Abort enabled |
True |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Quoted Identifiers Enabled |
True |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Is Read Committed Snapshot On |
True |
The default setting for transactions is AutoCommit. If transactions are required, they are opened explicitly.
These settings have proven to provide the best balance between data security and performance for One Identity Manager's massive parallel processing. Other transaction modes are not supported by One Identity Manager.
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Parameterization |
Forced |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Database file and date file group for memory-optimized tables |
Required |
One Identity Manager uses In-Memory-OLTP (Online Transactional Processing) for memory-optimized data accesses.
For the creation of memory-optimized tables, the following prerequisites must be met:
- A database file with the Filestream data file type must exist.
- A memory-optimized data filegroup must exist.
Before installation or update of the One Identity Manager database, the Configuration Wizard checks whether these requirements are fulfilled.
In the Configuration Wizard, repair methods are offered in order to create the database file and the data file group. The database file is created by the repair method in the directory of the data file (*.mdf). |
|
Table variable deferred compilation (DEFERRED_COMPILATION_TV) |
ON |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |
|
Interleaved execution (INTERLEAVED_EXECUTION_TVF) |
ON |
The setting is checked by the Configuration Wizard before installing or updating the One Identity Manager database and adjusted for the database if necessary. |

The following users are identified for using a One Identity Manager database on an SQL Server with the granular permissions concept. User permissions at server and database level are matched to their tasks.
-
Installation user
The installation user is needed for the initial installation of a One Identity Manager database using the Configuration Wizard.
NOTE: If you want to change to the granular permissions concept when you upgrade from version 8.0.x to 9.1.2, you will also require an installation user.
-
Administrative user
The administrative user is used by components of One Identity Manager that require authorizations at server level and database level, for example, the Configuration Wizard, the DBQueue Processor, or the One Identity Manager Service.
-
Configuration user
The configuration user can run configuration tasks within One Identity Manager, For example, creating customer-specific schema extensions or working with the Designer. Configuration users need permissions at the server and database levels.
-
End users
End users are only assigned permissions at database level in order, for example, to complete tasks with the Manager or the Web Portal.
For more information about minimum access levels for One Identity Manager tools, see the One Identity Manager Authorization and Authentication Guide.

Tips for using integrated Windows authentication
Integrated Windows authentication can be used without restriction for the One Identity Manager Service and the web applications. Integrated Windows authentication can be used for FAT clients. Use of Windows groups for logging in is supported. To ensure functionality it is strongly recommended you use SQL Server login.
To implement Windows authentication
-
Set up a SQL Server login for the user account on the database server.
-
Enter dbo as the default schema.
-
Assign the required permissions SQL server login.
To manage the One Identity Manager database in a managed instance in Azure SQL Database, you require the Business critical tier. For more detailed information, see the Microsoft site under https://azure.microsoft.com/en-us/services/sql-database/.
