Configuring DCE for Oracle DCE Integration

This chapter describes what you need to do to configure DCE to use Oracle DCE Integration after Oracle DCE Integration has been successfully installed.

This chapter contains the following topics:

• Task 1: Create New Principals and Accounts

• Task 2: Install the Key of the Server into a Keytab File

• Task 3: Configure DCE CDS for Use by Oracle DCE Integration

  More Information: See the list of related books and papers in "Related Publications" in the Preface.

The following is a list of tasks with examples you need to follow to configure DCE to use DCE Integration. The tasks assume that a DCE cell has been configured and the machines being used are part of that cell.

As the DCE cell administrator, you need to perform the following tasks:

• Task 1: Create New Principals and Accounts

• Task 2: Install the Key of the Server into a Keytab File

• Task 3: Configure DCE CDS for Use by Oracle DCE Integration

Task 1: Create New Principals and Accounts

First, add server principals using a procedure like the one below:

% dce_login cell_admin password
% rgy_edit
Current site is: registry server at /.../cell1/subsys/dce/sec/master
rgy_edit=>do p
Domain changed to: principal 
rgy_edit=> add oracle
rgy_edit=> do a
Domain changed to: account
rgy_edit=> add oracle -g none -o none -pw oracle_password -mp cell_admin_password
rgy_edit=> quit

bye 

In this example, you just created a DCE principal named oracle. The principal has a corresponding account with password password. The account does not belong to any DCE group or DCE profile.

You only need to do this once after DCE Integration has been installed. Also, you only need to do this procedure for the Oracle database server, not for the client.

Task 2: Install the Key of the Server into a Keytab File

In this step by step procedure, you install the key of the server into a keytab file: dcepa.key. This keytab file contains the password of the principal under which the Net8 listener starts. The Net8 listener reads this file to authenticate itself to DCE. You only need to do this once after DCE Integration has been installed. Also, you only need to do this procedure for the Oracle database server, not for the client.

.

Note: Remember to substitute the correct full pathname for the $ORACLE_HOME variable. If the specified directories do not already exist, you must create it before running the command. Enter the following to create the directories. mkdir $ORACLE_HOME/dcepa mkdir $ORACLE_HOME/dcepa/admin

Enter the following commands to generate the keytab file.

% dce_login cell_admin password
% rgy_edit
Current site is: registry server at /.../cell1/subsys/dce/sec/master
rgy_edit=> ktadd -p oracle -pw Oracle_password -f
$ORACLE_HOME/dcepa/admin/dcepa.key
rgy_edit=>quit
bye

Task 3: Configure DCE CDS for Use by Oracle DCE Integration

The /.:/subsys/oracle/names directory contains objects that map Net8 service names to connect descriptors, which are used by the CDS naming adapter.

The /.:/subsys/oracle/service_registry directory also contains objects that map the service name in DCE addresses to the network endpoint which is used by both DCE protocol adapter clients and servers.

Create Oracle Directories in the CDS Namespace

Perform the steps in this section after installing DCE Integration for the first time in a cell.

% dce_login cell_admin

Enter Password:(password not displayed)
$ cdscp
cdscp> create dir /.:/subsys/oracle
cdscp> create dir /.:/subsys/oracle/names
cdscp> create dir /.:/subsys/oracle/service_registry
cdscp> exit

Note: Create the directories on all CDS replicas.

Give Servers Permission to Create Objects in the CDS Namespace

Perform the following steps to add the principal oracle to the cds-server group.

$ dce_login cell_admin
Enter Password:   (password not displayed)
$ rgy_edit
rgy_edit=> domain group
Domain changed to: group
rgy_edit=> member subsys/dce/cds-server -a oracle
rgy_edit=> exit

Load Oracle Service Names into CDS

Load Oracle service names into the Cell Directory Service.
