12.3 Prerequisites and Considerations for Installing the Identity Manager Engine

Before installing the Identity Manager engine, you must install the Identity Vault. Also, the Identity Vault must contain a tree with at least one organizational unit, one user, and an iManager server.

Install the Identity Manager engine on the same server that hosts the Identity Vault. The installation program installs a 32-bit or a 64-bit Identity Manager based on the version of the Identity Vault.

(Conditional) To install the Remote Loader on the same computer as the Identity Manager engine, ensure that you select an operating system that supports both components. For more information about system requirements for the Remote Loader, see Section 15.5, Prerequisites and Considerations for Installing the Remote Loader.

(Conditional) If you install the Identity Manager engine as a non-root user, the installation process does not install NetIQ Sentinel Platform Agent, UNIX/Linux Account Driver, or Remote Loader. You must install these components separately.

In general, the number of drivers running on the server depends on the load that the drivers place on the server. Some drivers process a large quantity of objects while other drivers do not.

If you plan to synchronize millions of objects with each driver, limit the number of drivers on the server. For example, deploy fewer than 10 drivers of these drivers.

If you plan to synchronize 100 objects or fewer per driver, you might be able to run more than 10 drivers on the server.

To create a baseline on server performance which helps you determine the optimum number of drivers, use the health monitoring tools in iManager. For more information about the health monitoring tools, see Monitoring Driver Health in the NetIQ Identity Manager Driver Administration Guide.
