Synchronization Tasks

Last modified 30 Nov 2021 14:50 +01:00

Synchronization tasks are midPoint server tasks that handle bulk synchronization of midPoint objects. Synchronization tasks typically take care of scheduled user reconciliation or continuous live synchronization. But the tasks can be used in an ad-hoc manner to handle migration tasks such as initial user import or cleanup and administration tasks such as ad-hoc user recompute.

All the synchronization tasks are using the same synchronization mechanism. See the Synchronization page for an introduction.

For all the synchronization tasks to work correctly the synchronization section of resource configuration must be set up properly. See Synchronization Configuration page for more details.

Synchronization Tasks

Main synchronization tasks are:

Target Specification

The synchronization task needs to know what it has to process:

MidPoint 4.4 and After

The resource objects are specified using resourceObjects part of the respective work definition. The following properties can be defined:

  • resourceRef,

  • kind,

  • intent,

  • objectclass.

In some cases, explicit query can be provided as well.

Before MidPoint 4.4

The resource is specified by using the objectRef property of the task. The objects are specified using the properties objectclass, kind and intent of the task extension. Sometimes, objectQuery extension property can be provided as well.

Import

Import is usually one-time activity that imports accounts (or other kind of resource objects) into midPoint. Please see Import and Reconciliation.

An Example

The following task will import all objects of inetOrgPerson object class from resource ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2. The task will run only once.

We show both new syntax - available since midPoint 4.4 - and legacy one - available in midPoint 4.3.x and before. (Note that even in 4.4 you can use the legacy syntax as well, however, with some limitations.)

Import Accounts task (since 4.4)
<task>
    <name>Import: Example Resource</name>
    <ownerRef oid="00000000-0000-0000-0000-000000000002" type="UserType"/>
    <executionState>runnable</executionState>
    <activity>
        <work>
            <import>
                <resourceObjects>
                    <resourceRef oid="ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2"/>
                    <objectclass>ri:inetOrgPerson</objectclass>
                </resourceObjects>
            </import>
        </work>
    </activity>
</task>
Import Accounts task (before 4.4)
<task xmlns:mext="http://midpoint.evolveum.com/xml/ns/public/model/extension-3">
    <name>Import: Example Resource</name>
    <extension>
        <mext:objectclass>ri:inetOrgPerson</mext:objectclass>
    </extension>
    <ownerRef oid="00000000-0000-0000-0000-000000000002" type="UserType"/>
    <executionStatus>runnable</executionStatus>
    <category>ImportingAccounts</category>
    <handlerUri>http://midpoint.evolveum.com/xml/ns/public/model/synchronization/task/import/handler-3</handlerUri>
    <objectRef oid="ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2" type="ResourceType"/>
    <recurrence>single</recurrence>
</task>

Reconciliation

Reconciliation is one-time or recurring activity that reconciles the state on a resource (either source or target one) with midPoint. It is basically an import plus a couple of other activities. Please see Import and Reconciliation.

An Example

The following task will run reconciliation on resource ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2. It will reconcile objects of inetOrgPerson object class. The reconciliation will be running every hour (3600 seconds).

Reconciliation task (since 4.4)
<task>
    <name>Reconciliation: Example Resource</name>
    <ownerRef oid="00000000-0000-0000-0000-000000000002" type="UserType"/>
    <executionState>runnable</executionState>
    <schedule>
        <interval>3600</interval>
    </schedule>
    <activity>
        <work>
            <reconciliation>
                <resourceObjects>
                    <resourceRef oid="ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2"/>
                    <objectclass>ri:inetOrgPerson</objectclass>
                </resourceObjects>
            </reconciliation>
        </work>
    </activity>
</task>
Reconciliation task (before 4.4)
<task xmlns:mext="http://midpoint.evolveum.com/xml/ns/public/model/extension-3">
    <name>Reconciliation: Example Resource</name>
    <extension>
        <mext:objectclass>ri:inetOrgPerson</mext:objectclass>
    </extension>
    <ownerRef oid="00000000-0000-0000-0000-000000000002" type="UserType"/>
    <executionStatus>runnable</executionStatus>
    <category>Reconciliation</category>
    <handlerUri>http://midpoint.evolveum.com/xml/ns/public/model/synchronization/task/reconciliation/handler-3</handlerUri>
    <objectRef oid="ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2" type="ResourceType"/>
    <recurrence>recurring</recurrence>
    <schedule>
        <interval>3600</interval>
    </schedule>
</task>

Live Synchronization

Live synchronization processes changes from a resource in a real-time or near real-time. Please see Live Synchronization.

An Example

The following task will run live synchronization on resource ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2. It will synchronize objects of inetOrgPerson object class. The synchronization will be running every 10 seconds.

Live synchronization task (since 4.4)
<task>
    <name>Live synchronization: Example Resource</name>
    <ownerRef oid="00000000-0000-0000-0000-000000000002" type="UserType"/>
    <executionState>runnable</executionState>
    <schedule>
        <interval>10</interval>
    </schedule>
    <activity>
        <work>
            <liveSynchronization>
                <resourceObjects>
                    <resourceRef oid="ef2bc95b-76e0-48e2-86d6-3d4f02d3e1a2"/>
                    <objectclass>ri:inetOrgPerson</objectclass>
                </resourceObjects>
            </liveSynchronization>
        </work>
    </activity>
</task>
Live synchronization task (before 4.4)
<task xmlns:mext="http://midpoint.evolveum.com/xml/ns/public/model/extension-3">
    <name>Live synchronization: Example Resource</name>
