CHAPTER 16. Configuring the DCE CDS Naming Adapter

Using DCE's CDS (Cell Directory Service) to Perform Name Lookup
Clients Outside DCE Can Still Connect to Oracle Servers in DCE

The DCE CDS Native Naming adapter enables you to load Oracle service names into CDS. It enables clientsto access Oracle servers using the CDS names service.

The CDS naming adapter must be installed on all clients and servers that will use CDS for name resolution. To install the CDS adapter, use the Oracle Installer. Refer to your platform-specific documentation for information.

To configure the CDS naming adapter on Oracle clients and servers, follow the instructions in Chapter 10.

To configure CDS to use the Oracle DCE CDS Native Naming adapter, follow the instructions in "Configuring CDS for Use by DCE Integration," in Chapter 9.

Refer to the chapter that discusses naming issues in Understanding SQL*Net for information on how you can use the Native Naming Adapters provided by Oracle in your enterprise network.

Using DCE's CDS (Cell Directory Service) to Perform Name Lookup

After the administrator has installed the CDS Native Naming Adapter on all clients and servers, and performed the necessary configuration described in Chapters 9 and 10, users and applications are able to access Oracle services in DCE's CDS (Cell Directory Service). For example, a service name such as "financials" and its corresponding address can be stored in DCE's CDS.

Typically, users can connect to Oracle services using the familiar Oracle service name (if the database is in the user's default domain):

	sqlplus /@sales

Note: In practice, users can omit the username and password, in order to use DCE authentication.

	sqlplus <username>/<password>@sales

if users prefer to enter the username and password, or

	sqlplus scott/tiger@sales.us.oracle.com

if the database is not located in the user's default domain.

Clients Outside DCE Can Still Connect to Oracle Servers in DCE

A client without access to DCE and CDS can still connect to an Oracle server that has been integrated into DCE. However, the client can connect to an Oracle server only if a listener is configured to listen on a non-DCE address. After another listener is configured, clients can use normal Oracle and SQL*Net procedures to connect to an Oracle server in DCE. The service name would be looked up and resolved to its network address using a TNSNAMES.ORA file, not the CDS name server.
