To enable third-party metadirectory solutions to retrieve changes from Oracle Internet Directory, perform the tasks described in this section.
To bootstrap a directory to synchronize data between a local directory and Oracle Internet Directory, do the following:
Find the number of the last change recorded in Oracle Internet Directory. This number is contained in the DSE root attribute, lastChangeNumber
.
To find the number of the last change recorded in Oracle Internet Directory, use ldapsearch. Enter the following command:
ldapsearch -h host_name -p port_number -s base -b "" 'objectclass=*' lastchangenumber
If the change log does not contain change entries because they have been purged, then the last change number retrieved is 0
(zero).
Use ldifwrite to export data from Oracle Internet Directory into an LDIF file.
Convert the LDIF file to a format suitable to the client directory, then load it into the client directory.
Note: Initial bootstrapping is not required with a new installation of Oracle Internet Directory. In this case, the current change number of the newly installed Oracle Internet Directory is0 (zero).

To enable a third-party metadirectory solution to synchronize with Oracle Internet Directory, you must create a change subscription object for it in Oracle Internet Directory. This gives the third-party metadirectory solution access to change log objects stored in Oracle Internet Directory.
The change subscription object is an entry located under the following container in Oracle Internet Directory:
cn=Subscriber Profile,cn=ChangeLog Subscriber,cn=Oracle Internet Directory
This change subscription object provides a unique credential for a third-party metadirectory solution to bind with Oracle Internet Directory and to retrieve changes from it. You associate the change subscription object with the auxiliary object class orclChangeSubscriber
. This object class has several attributes, of which the following are mandatory:
userPassword
Password to be used by the directory when accessing the change log object in Oracle Internet Directory
orclLastAppliedChangeNumber
Number of the change applied during the last synchronization. This attribute allows the directory to retrieve only the changes in Oracle Internet Directory it has not already applied.
To create a change subscription object, use ldapadd. The following example uses an input file, named add.ldif
, to create and enable a change subscription object, named my_change_subscription_object
, under the container cn=Subscriber Profile,cn=ChangeLog Subscriber,cn=Oracle Internet Directory
. The orclLastAppliedChangeNumber
is the current change number in the directory before initial bootstrapping—in this example, 250.
Edit file add.ldif
:
dn: cn=my_change_subscription_object,cn=Subscriber Profile,
cn=ChangeLog Subscriber,cn=Oracle Internet Directory
userpassword: my_password
orclLastAppliedChangeNumber: 250
orclSubscriberDisable: 0
objectclass: orclChangeSubscriber
objectclass: top
Add the entry:
ldapadd -h my_host -p 389 -f add.ldif
