CA Identity Manager Implementation Guide - CA Technologies

Choose a Method to Import UsersImport Users Through Identity ManagerCA Identity Manager provides the following methods for adding users to a userstore that it manages directly.Method Features LimitationsBulk LoaderAllows you to use the BulkLoader task in the UserConsole to upload feeder filesthat are used to manipulatelarge numbers of managedobjects simultaneously.The advantage of the BulkLoader method is that youcan automate the process ofmanipulating a large numberof managed objects using aninformation (feeder) file. TheBulk Loader task can also bemapped to a workflowprocess.If you are using the BulkLoader, you may seeout-of-memory exceptionsdepending on the number ofusers you are importing.To address this issue,increase the JVM memorysettings.Remote TaskInvocation viaTask ExecutionWeb Service(TEWS)Allows execution of any CAIdentity Manager task that isenabled for Web Services,including the Create Usertask.If the task is configured forUser Synchronization, CAIdentity Manager will executeany applicable identitypolicies.Performance characteristicsof web service model may notbe well-suited forhigh-throughputrequirements of bulk importoperationsIM API ■ Provides User-based APIsthat can be invokeddirectly for creating usersvia a Java client■Bypasses audit andsecurity mechanismsprovided by the TaskServer.■Provides the highestthroughput capabilities.■Does not supportexecution of IdentityPolicies.Note: For more information about the Bulk Loader, see the AdministrationGuide.
