Applies to:

Identity Manager - Version 11.1.2.2.1 and later
Oracle Unified Directory - Version 11.1.1.5.0 and later

The job runs successfully for a while after it is scheduled. What we've noticed is after OUD purges the changelog on its side (the duration is set by the value replication-purge-delay), then the aforementioned OIM scheduled tasks fail. The error we see is:

One has to then manually copy the latest lastExternalChangelogCookie from OUD and replace it on the OIM side (on the LDAP Sync jobs). After that when we run the job, it starts to work again.
