Provisioning provides high availability solutions in the following three tiers:
The clients are the Identity Manager User Console, Identity Manager Management Console and the Provisioning Manager. You can group clients together based on their geographic locations, organizational units, business functions, security requirements, provisioning workload, or other administration needs. Generally, we recommend keeping clients close to the endpoints they manage.
Clients use primary and alternate Provisioning Servers, in order of their failover preference. Client requests continue to be submitted to the first server until that server fails, that is, the connection stays active until the server fails. In case of a failure, the client checks the list of configured servers, in order of preference, to find the next available server.
The Provisioning Server can have multiple connector servers in operation. Each connector server handles operations on a distinct set of endpoints. Therefore, your organization may choose to deploy connector servers on systems that are close in the network to the endpoints. For example, if you have many UNIX /etc endpoints, you might have one connector server installed on each of these servers so that each connector server controls only the endpoint on the server where it is installed.
Installing Connector Servers close to the endpoints also reduces the delays in managing accounts on those endpoints.
You can use another CA Directory router to send server requests to Provisioning Directories. You can replicate multiple Provisioning Directories for load‑balancing, failover, or both.
