Configure an Incremental Job

This guide shows how to configure the relevant tasks to make a job incremental.

Overview​

When configured as such, Identity Manager is able to remember after synchronization which resources were modified, i.e. created, updated and/or deleted.

It allows future tasks to be executed only on modified resources, in order to minimize jobs' execution times and costs.

See the Set Up Incremental Synchronization topic for additional information on a full Incremental job.

Configure a Job to Be Incremental​

Configure a job to be incremental by proceeding as follows:

  1. Configure the synchronization task ( Synchronize Task ) with DoNotDeleteChanges set to true.

    This way, Identity Manager keeps the list of all changed resources.

    For example, to synchronize incrementally the Active Directory:


    <SynchronizeTask Identifier="SynchronizeActiveDirectory_DoNotDeleteChanges" DisplayName_L1="AD - Synchronization (server side)" Connector="AD" Level="2" Type="ActiveDirectory" DoNotDeleteChanges="true" >  ...
    </SynchronizeTask>

  2. Tag all changed resources by running Set Recently Modified Flag Task after SynchronizeTask.

    For example, following the synchronization task for the Active Directory:


    <SetRecentlyModifiedFlagTask Identifier="SetRecentlyModifiedFlag" DisplayName_L1="Tag Modified Objects" Level="3">  <TaskDependsOnTask ParentTask="SynchronizeActiveDirectory_DoNotDeleteChanges" /></SetRecentlyModifiedFlagTask>

  3. Configure the next tasks with Dirty set to true to apply them only to resources flagged as "dirty", i.e. recently modified.

    For example, to compute correlation keys incrementally:


    <ComputeCorrelationKeysTask Identifier="ComputeCorrelationKeys_Incremental" DisplayName_L1="Compute Correlations (Incremental)" Level="5" Dirty="true">  <TaskDependsOnTask ParentTask="SetRecentlyModifiedFlag" />  <TaskEntityType EntityType="Directory_User" />  ...
    </ComputeCorrelationKeysTask>
