Connecting to an Oracle Database in DCE

This chapter explains how to connect to an Oracle database after having installed Oracle DCE Integration and having configured both DCE and Oracle to use Oracle DCE Integration.

This chapter covers the following topics:

Starting the Network Listener

To start the Net8 listener, do the following:

  1. To start the listener, enter the following commands:

    % dce_login principal_name password 
    %  lsnrctl start listener_name

    For example, if the listener name is LSNR_DCE in listener.ora, enter the following to start the listener:

    % dce_login oracle orapwd
    % lsnrctl start LSNR_DCE

    To make sure the server registered its binding handler with rpcd, enter:

    % rpccp show mapping

    In the computer response, look for the line that includes the dce_service_name that is part of the listener address.

  2. To make sure the service has been created, search for the dce_service_name as follows:

    % cdscp show object "/.:/subsys/oracle/service_registry/dce_service_

    For example:

    % cdscp show object "/.:/subsys/oracle/service_registry/dce_svc"

    This shows you the mapping in the CDS namespace that the listener has chosen for the endpoint. For example:

              OBJECT    /.../subsys/oracle/service_registry/dce_svc
                  AT   1995-05-15-17:10:52
    RPC_ClassVersion = 0100
             CDS_CTS = 1995-05-16-00:05:01.221106100/aa-00-04-00-3e-8c           
             CDS_UTS = 1995-05-16-00:05:01.443343100/aa-00-04-00-3e-8c 		  
           CDS_Class = RPC_Server
    CDS_ClassVersion = 1.0
          CDS_Towers = :
               Tower = ncacn_ip_tcp:[]

Connecting to an Oracle Database Server in the DCE Environment

To connect to an Oracle server in the DCE environment, do one of the following:

  1. After externally-identified accounts have been set up, you can take advantage of DCE authentication to log into Oracle without providing any user name/password information. To use this single sign-on capability, just log in to DCE using a command like the following:

    % dce_login principal_name password

    For example:

    % dce_login oracle orapwd


    You only need to enter the dce_login command once. If you are already logged into DCE, you do not need to log in again.  

    You can now connect to an Oracle server without using a user name or password. Enter a command like the following:

    % sqlplus /@net_service_name

    where net_service_name is the database service name.

    For example:

    % sqlplus /@ORADCE

    More Information:

    See Oracle8i Distributed Database Systems.  

  2. From a client, you can still connect with a user name/password:

    % sqlplus username/password@net_service_name

    where net_service_name is the Net8 service name.

    For example:

    % sqlplus scott/tiger@ORADCE
