Description description

Environment

Adobe Experience Manager as a Cloud Service (AEMaaCS)

Issue/Symptoms

This article is a sample configuration for setting up workflow purge as a maintenance task in AEM as a Cloud Service.

Reference:
Adobe Experience Manager Maintenance Guide

Resolution resolution

To set up a workflow purge as a maintenance task, follow these steps to configure the necessary elements in your Maven project:

Step1. OSGi configuration

Create an OSGi configuration file.

Path: ui.config/src/main/content/jcr_root/apps/>project_name</osgiconfig/config.author/ com.adobe.granite.workflow.purge.Scheduler >project_name<.cfg.json

Example configuration:

{
  "scheduledpurge.workflowStatus": "COMPLETED",
  "scheduledpurge.name": "Workflow Purge",
  "scheduledpurge.daysold": 30,
  "scheduledpurge.modelIds": [ ] ,
  "scheduledpurge.purgePackagePayload":true
}

This configuration is to delete workflow instances that were completed more than 30 days ago.

Step2. Configure the maintenance window

  1. Create a weekly maintenance window node. Path: ui.apps/src/main/content/jcr_root/apps/settings/granite/operations/maintenance/granite_weekly/.content.xml
    Example configuration:

    code language-none 
    <?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
   xmlns:jcr="http://www.jcp.org/jcr/1.0"
   jcr:primaryType="sling:Folder"
   sling:configCollectionInherit="true"
   sling:configPropertyInherit="true"
   windowEndTime="15:30"
   windowSchedule="weekly"
   windowScheduleWeekdays="[ 5,5] "
   windowStartTime="14:30"/>

    This configuration runs the maintenance task every Thursday from 14:30 to 15:30 (UTC).

  2. Create the workflow purge task node. Path: ui.apps/src/main/content/jcr_root/apps/settings/granite/operations/maintenance/granite_weekly/granite_WorkflowPurgeTask/.content.xml
    Example configuration:

    code language-none 
    <?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0" xmlns:nt="http://www.jcp.org/jcr/nt/1.0"
  jcr:primaryType="nt:unstructured"
  sling:resourceType="granite/operations/components/maintenance/task"
  granite.maintenance.name="WorkflowPurgeTask"
  granite.task.hint="HINT: Please add workflow models to be deleted to the workflow-purge configuration, which is available under Adobe Granite Workflow Purge Configuration under Web Console Configuration-Manager."/>

  3. Configure a package filter for node installation. Path: ui.apps/src/main/content/META-INF/vault/filter.xml
    Example configuration:

    code language-none 
    <workspaceFilter version="1.0">
  ...
<!-- Add the below line to existing settings -->
<filter root="/apps/settings/granite/operations/maintenance/granite_weekly"/>
</workspaceFilter>>

  4. Update the filevault-package-maven-plugin filter: Path: ui.apps.structure/pom.xml
    Example configuration:

    code language-none 
    <plugin>
    <artifactId>filevault-package-maven-plugin</artifactId>
        <configuration>
            <filters>
                      ...
                <!-- Add the below lines to existing settings -->
                <filter><root>/apps/settings/granite</root></filter>
                <filter><root>/apps/settings/granite/operations</root></filter>
                <filter><root>/apps/settings/granite/operations/maintenance</root></filter>
                <filter><root>/apps/settings/granite/operations/maintenance/granite_weekly</root></filter>
            </filters>
        </configuration>
</plugin>

Step3. Local testing

Build and install the configuration to the local SDK. Verify the result of the workflow purge task.

$ mvn clean install -PautoInstallSinglePackage

Step4. Cloud deployment

Once validated, commit and push the configuration to the Git repository. Run the Cloud Manager pipeline to deploy it to your AEM as a Cloud Service environment. Make sure to deploy the configuration from the lower environments.
