OUD Replication - Using the External ChangeLog (Doc ID 1406188.1)

Last updated on APRIL 27, 2023

Applies to:

Oracle Unified Directory - Version 11.1.1.5.0 and later
Identity Manager - Version 11.1.2.1.0 to 11.1.2.1.0 [Release 11g]
Information in this document applies to any platform.

Purpose


The External Change Log (ECL) provides an alternate view of the replication change log.

The ECL is based on the LDAP changelog draft (Definition of an Object Class to Hold LDAP Change Records) but does not strictly support this change log.
The LDAP change log draft uses an integer as the key to browse the change log whereas the ECL uses a cookie.


The following document explains how to use the External Change Log (ECL).
