Pausing handling of target system specific processes
Sometimes a target system is not available. For example, during . If are started or data is changed in One Identity Manager during this time, synchronization and provisioning tasks are queued in the . As long as the target system is down, these processes are sent into a FROZEN state and must be verified and re-enabled once the target system is available again.
One Identity Manager allows you to temporarily label the target system connection as offline. During this offline phase, synchronization is not run and provisioning tasks are put on hold. The respective pauses Job queue processing. Once the target system is available again, the system connection must be switched to online. This starts Job queue processing again and all pending processes are run in sequence.
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.

Enable offline mode
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 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 . 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 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 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 , 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.
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 program shows when a Job server has been switched offline and the corresponding tasks are not being processed.

Once the target system is available again, switch it back to online.
If offline mode should not be used for a target system in general, disable the option on the base object.

Maintaining synchronization information in column definitions
All columns in the One Identity Manager schema can store additional information, which is evaluated when is set up. This information is mainly required for setting up synchronization with the One Identity Manager connector, but can also be used when synchronizing tables and columns.
Settings in the synchronization information do not override the default behavior of the One Identity Manager connector. They provide information if the default behavior cannot be determined automatically. For example, if a column is marked as a mandatory column by the MinLen='1' property, the connector will automatically recognize it as a mandatory column even if the Mandatory column value is disabled in the Synchronization information field.
To edit synchronization information in column definitions
-
In the , select One Identity Manager .
-
Select the table and start the Schema Editor with the Show table definition task.
-
Select the column and then the Column properties view.
-
Select the More tab.
-
Select all applicable values from the Synchronization information menu.
-
Not relevant for synchronization: The column is not displayed in the .
-
Has unique value: The column contains a unique value.
-
Has conditional default value: The column contains a value that is formatted automatically under certain conditions, for example by a customizer.
-
Has a default value: The column contains a value that is formatted automatically, for example by a formation rule.
-
Conditional mandatory column: The column is a mandatory column under certain conditions, for example if the value is checked by triggers.
-
Mandatory column: The column is a mandatory column.
