Task 3: Configure Mapping Rules for the Oracle Human Resources Connector

11 Synchronizing with Third-Party Metadirectory Solutions 11-1 11 Synchronizing with Third-Party Metadirectory Solutions To enable synchronization with supported third-party metadirectory solutions, Oracle Internet Directory uses change logs. The Oracle Directory Integration Platform does not provide mapping or scheduling services for third-party metadirectory solutions. This chapter describes how change log information is generated and how supporting solutions use that information. It tells you how to enable third-party metadirectory solutions to synchronize with Oracle Internet Directory. This chapter contains these topics: ■ About Change Logs ■ Enabling Third-Party Metadirectory Solutions to Synchronize with Oracle Internet Directory ■ Synchronization Process ■ Disabling and Deleting Change Subscription Objects

11.1 About Change Logs

Oracle Internet Directory records each change as an entry in the change log container. A third-party metadirectory solution retrieves changes from the change log container and applies them to the third-party directory. To retrieve these changes, the third-party metadirectory solution must subscribe to the Oracle Internet Directory change logs. Each entry in the change log has a change number. The third-party metadirectory solution keeps track of the number of the last change it applied, and it retrieves from Oracle Internet Directory only those changes with numbers greater than the last change it applied. For example, if the last change a third-party metadirectory solution retrieved was a number of 250, then subsequent changes it retrieves would be greater than 250. Note: If a third-party metadirectory solution is not subscribed to the Oracle Internet Directory change logs, and the first change it retrieves is more than one number higher than the last change it last applied, then some of the changes in the Oracle Internet Directory change log have been purged. In this case, the third-party metadirectory solution must read the entire Oracle Internet Directory to synchronize its copy with that in Oracle Internet Directory.
