Configuring Oracle Database and Oracle Net Services for Oracle DCE Integration

Conﬁguring Oracle DCE Integration 10-19

Task 6: Conﬁgure Clients to Use DCE CDS Naming

Clients typically use Cell Directory Services (CDS) to resolve Oracle service names

to addresses. Perform the following steps to conﬁgure CDS:

■ Step 1: Enable CDS for use in Performing Name Lookup

■ Step 2: Modify the CDS Attributes File and Restart the CDS

■ Step 3: Create a tnsnames.ora File for Loading Oracle Connect Descriptors into

CDS

■ Step 4: Load Oracle Connect Descriptors into CDS

■ Step 5: Delete or Rename the tnsnames.ora File

■ Step 6: Modify the sqlnet.ora File to Resolve Names in CDS

Step 1: Enable CDS for use in Performing Name Lookup

To use CDS for name resolution, the DCE Integration CDS Naming Adapter must

be installed on all clients and servers that use CDS. Also, the CDS namespace must

have been conﬁgured for use by DCE Integration.

Option Description

TRUE The default value. Select TRUE if using just the SERVER_

PRINCIPAL format, without the CELL_NAME.

An example of a user speciﬁed in this format is as follows:

oracle

TRUE is an appropriate option if users are making connections

within a single cell, or if naming conventions in the network

assure that users in different cells do not have duplicate names.

FALSE Select FALSE when using the CELLNAME/SERVER_PRINCIPAL

format. An example of a user speciﬁed in this format is as

follows:

CELL1/ORACLE

FALSE is an appropriate option if users are making connections

across cells and there can be users in different cells with

identical name

Note: Upon completion of this task, you can connect to an Oracle

database in your DCE environment.
