To resolve a connect descriptor using a centralized directory server, the steps are as follows:
1. Oracle Net, on behalf of the client, contacts the directory server to obtain the resolution
for the connect identifier to a connect descriptor.
2. The directory server takes the connect identifier, locates the associated connect
descriptor, and returns the descriptor to Oracle Net.
3. Oracle Net uses the resolved descriptor to make the connection request to the correct
listener.
The directory server uses a tree structure in which to store its data. Each node in the tree is
an entry. A hierarchical structure of entries is used, called a directory information tree (DIT), and
each entry is identified by a unique distinguished name (DN) that tells the directory server exactly
where the entry resides. DITs can be structured to use an existing Domain Name System (DNS),
organizational or geographical lines, or Internet naming scheme.
Using a DIT that is organized along organizational lines, for example, the DN for the HR server
could be this: (dn: cn=HR, cn=OracleContext, dc=us, dc=ourcompany, dc=com).
