The Net Configuration Assistant is used to declare how to access the OID server.
It declares the directory type as Oracle Internet Directory and defines the access
parameters (hostname, LDAP port and LDAP SSL port). Usually port 389 is used for
non SSL OID and port 636 is used for SSL OID port, you should first verify which
ports were actually assigned by taking a look at the <Oracle Home>/install/
portlist.ini or from the Enterprise Manager Application Server Control Ports tab.
Registering the database against the OID
The Database must be registered against the OID. The Database Configuration
Assistant is the tool used for this purpose. When asked if the database is to be
registered against the OID, the answer should be Yes ( A ). Next there are two
credentials that must be provided, one for the orcladmin user (OID Manager) the
distinguished name cn=orcladmin must be provided as well as its password; the
second requested credential is the Oracle Wallet password. It is confirmed and the
configuration is accepted. After a while the database is registered against the OID. This
operation should not take a long time as this is done by querying the LDAP server
