Tuning Roadmap

How well your Identity Manager solution performs can depend on the following deployment-specific settings:

• Resource configuration

• How many resources are connecting

• What type of resources are connecting

• How attributes are mapped on the resources

• Exact resource version

• Network topology

• Number (and distribution) of domain controllers

• Number of installed Identity Manager Gateways

• Number of concurrent settings

• Number of concurrent processes (running workflows)

• Number of concurrent users

• Number of concurrent Identity Manager administrators

• Total number of users under management

When you are trying to debug performance problems, start by analyzing and describing the problem. Ask yourself the following questions:

• Where do you see the performance issue? In reconciliation, workflows, custom workflows, GUI page loading, provisioning, Access Review?

• Are you CPU bound, memory bound, resource bound, or network bound?

• Have you examined your configuration (hardware, network, parameters, and so forth) for problems?

• Have you recently changed anything in your deployment environment?

• Have you tried profiling troublesome resources natively to see if the problem is on the resource side and not with Identity Manager?

• What size are the views?

• Are you provisioning to several resources?

• Are resources on slow networks connecting to Identity Manager?

• Are you running additional applications on the server with Identity Manager?

• Do your organizations have a Rule-Driven Members rule?

• Have you run a series of thread dumps to see if there is a consistent pattern?

  Note –

  Looking at just a single thread dump can be misleading.

• Have you recently turned on tracing?

• Have you checked your JVM garbage collection?

• Have you added organizations that are adding load to memory management?
