Runtime Components TuningRuntime Components TuningBusiness changes in Identity Manager are accomplished through tasks. A taskincludes one or more events, which represent activities that Identity Managerperforms to complete the task. For example, a Create User task may include theCreateUserEvent and the the AddToGroupEvent.Identity Manager includes the following components, which process tasks andevents at runtime:■■Identity Manager databases, which support Identity Manager functionalityJMS messages, which are responsible for processing eventsTuning Identity Manager DatabasesWhen executing tasks, Identity Manager uses the following databases:■Task persistenceMaintains information about Identity Manager tasks and events over time.This allows Identity Manager to restore the last known state of events andtasks in the case of system failure.Note: This database has the most significant impact on Identity Managerperformance because the task and its events are saved and retrieved fromthe database during state transitions.■AuditProvides a historical record of operations that occur in an Identity Managerenvironment.■WorkflowStores workflow process definitions, jobs, scripts, and other data required bythe workflow engine.■ReportingStores snapshot data, which reflects the current state of objects in IdentityManager at the time the snapshot is taken.Chapter 6: Optimizing Identity Manager 91
