Individual objects can only be synchronized if the object is already present in the One Identity Manager database. The changes are applied to the mapped object properties. If a membership list belongs to one of these properties, the entries in the assignment table will also be updated.
NOTE: If the object is no longer present in the target system, then it is deleted from the One Identity Manager database.
To synchronize a single object
-
In the Manager, select the Universal Cloud Interface category.
-
Select the object type in the navigation view.
-
In the result list, select the object that you want to synchronize.
-
Select the Synchronize this object task.
A process for reading this object is entered in the job queue.
Features of synchronizing memberships
If you synchronize changes in an object's member list, run single object synchronization on the assignment's root object, The base table of an assignment contains an XDateSubItem column containing information about the last change to the memberships.
Example:
Base object for assigning user accounts to groups is the group.
In the target system, a user account was assigned to a group. To synchronize this assignment, in the Manager, select the group that the user account was assigned to and run single object synchronization. In the process, all of the group's memberships are synchronized.
The user account must already exist as an object in the One Identity Manager database for the assignment to be made.
Detailed information about this topic
Synchronization Editor helps you to analyze and eliminate synchronization errors.
-
Simulating synchronization
The simulation allows you to estimate the result of synchronization. This means you can, for example, recognize potential errors in the synchronization configuration.
-
Analyzing synchronization
You can generate the synchronization analysis report for analyzing problems which occur during synchronization, for example, insufficient performance.
-
Logging messages
One Identity Manager offers different options for logging errors. These include the synchronization log, the log file for One Identity Manager Service, the logging of messages with NLOG, and similar.
-
Reset start information
If synchronization stopped unexpectedly, for example, because a server was not available, the start information must be reset manually. Only then can the synchronization be restarted.
For more information about these topics, see the One Identity Manager Target System Synchronization Reference Guide.

By default, objects with incorrect data are not synchronized. These objects can be synchronized once the data has been corrected. In certain situations, however, it might be necessary to synchronize objects like these and ignore the data properties that have errors. This synchronization behavior can be configured in One Identity Manager.
To ignoring data errors during synchronization in One Identity Manager
-
In the Synchronization Editor, open the synchronization project.
-
Select the Configuration > One Identity Manager connection category.
-
In the General view, click Edit connection.
This starts the system connection wizard.
-
On the Additional options page, enable Try to ignore data errors.
This option is only effective if Continue on error is set in the synchronization workflow.
Default columns, such as primary keys, UID columns, or mandatory input columns cannot be ignored.
- Save the changes.
IMPORTANT: If this option is set, One Identity Manager tries to ignore commit errors that could be related to data errors in a single column. This causes the data changed in the affected column to be discarded and the object is subsequently saved again. This effects performance and leads to loss of data.
Only set this option in the exceptional circumstance of not being able to correct the data before synchronization.
If a target system connector is not able to reach the target system temporarily, you can enable offline mode for the target system. This stops target system specific processes from being frozen and having to be manually re-enabled later.
Whether offline mode is generally available for a target system connection is set in the base object of the respective synchronization project. Once a target system is truly unavailable, the target system connection can be switched offline and online again with the Launchpad.
In offline mode, all Job servers assigned to the base object are stopped. This includes the synchronization server and all Job servers involved in load balancing. If one of the Job servers also handles other tasks, these are not processed either.
Prerequisites
Offline mode can only be specified for a base object if certain prerequisites are fulfilled.
-
The synchronization server is not used for any other base object as a synchronization server.
-
If a server function is assigned to the base object, none of the Job servers with this server function may have any other server function (for example, update server).
-
A dedicated synchronization server must be set up to exclusively process the Job queue for this base object. The same applies to all Job servers that are determined by the server function.
To allow offline mode for a base object
-
In the Synchronization Editor, open the synchronization project.
-
Select the Base objects category.
-
Select a base object in the document view and click 
.
-
Enable Offline mode available.
- Click OK.
- Save the changes.
IMPORTANT: To prevent data inconsistencies, the offline phase should be kept as short as possible.
The number of processes to handle depends on the extent of the changes in the One Identity Manager database and their effect on the target system during the offline phase. To establish data consistency between the One Identity Manager database and the target system, all pending processes must be handled before synchronization can start.
Only use offline mode, if possible, for short system downtimes such as maintenance windows.
To flag a target system as offline
-
Start the Launchpad and log in on the One Identity Manager database.
-
Select Manage > System monitoring > Flag target systems as offline.
-
Click Run.
This opens the Manage offline systems dialog. The Base objects section displays the base objects of target system connections that can be switched to offline.
-
Select the base object whose target system connection is not available.
-
Click Switch offline.
- Confirm the security prompt with OK.
This stops all the Job servers assigned to the base object. No more synchronization or provisioning Jobs are performed. The Job Queue Info program shows when a Job server has been switched offline and the corresponding tasks are not being processed.
For more information about offline mode, see the One Identity Manager Target System Synchronization Reference Guide.
