7 Best practices

The IBM Tivoli Identity Manager product can be set up and configured in many ways. The following are some suggested best practices to help guide you in setting up your environment.

•Each agent modifies the LDAP schema by adding new attributes to support a new service. These attributes are created without indexes, and for services that service thousand of users, a large benefit can be achieved by adding indexes to attributes with many members.

•Complicated provisioning policies can result in complicated directory and database queries with poor performance. Policies with small numbers of roles and services will perform best.

•Dynamic roles affect people in a given scope, either one-level or subtree. When a person object within that scope is modified or added, that role must be re-evaluated. This is true for every dynamic role in the system. For instance, if there are three dynamic roles with subtree scope and a person object within that scope is updated, all three dynamic roles will be re-evaluated. For this reason, it is recommended that you limit the number of dynamic roles, either by number or by scope, that affect people that are modified frequently. It doesn’t matter if the dynamic role ends up enrolling the person or not, the evaluation itself is the performance-impacting overhead.

•Limiting the scope (via placement within the organizational tree) and number of ACIs will increase performance by requiring fewer evaluations. When doing a person search via the APIs, be sure to limit the scope of your search to be as narrow as possible to avoid the system evaluating more ACIs than necessary.

•When enabling WebSphere global security, do not enable Java 2 security unless it is required for your environment. Enabling WebSphere global security automatically enables Java 2 security unless it is explicitly disabled. Having Java 2 security enabled can cause a significant performance degradation to IBM Tivoli Identity Manager.
