Oracle9i Database Release 2 can work with Oracle Internet Directory Release 9.2 or Release 9.0.4. Oracle Database 12c Release 1 (12.1) requires Oracle Internet Directory 9.0.4 or later. In case you are using Oracle Internet Directory Release 9.2, you need to upgrade it to Release 9.0.4.
The following list discusses upgrading Oracle Internet Directory Release 9.2 to Oracle Internet Directory Release 9.0.4:
Use Oracle Internet Directory Configuration Assistant to upgrade Oracle Internet Directory. This is required if you want to register Oracle Database 12c Release 1 (12.1) instances in the directory.
Upgrade Oracle Contexts used for Enterprise User Security to Identity Management Realms, if they are not root contexts. Use the Oracle Internet Directory Configuration Assistant command-line utility as follows:
oidca mode=CTXTOIMR
This step is required if you want to register an Oracle Database 12c Release 1 (12.1) instance in a realm.
You cannot use the root Oracle Context for Oracle Database 12c Release 1 (12.1) databases because it is not an Identity Management Realm.
Use Oracle Internet Directory tools, such as ldapmodify and bulkmodify, to add the orcluserV2 objectclass to existing user entries. This objectclass is required for users to change their database passwords, and for kerberos authentication to the database.
In a realm that contains both Oracle9i Database and Oracle Database 12c Release 1 (12.1), use a DAS-based tool in Oracle Internet Directory Release 9.0.4 to create and manage users. You can use either Oracle Internet Directory Self-Service Console or Enterprise Security Manager Console. Do not use Enterprise Security Manager or Enterprise Login Assistant from Oracle9i installations.
