B Upgrade Considerations for Oracle Net Services

This appendix describes coexistence and upgrade issues for Oracle Net Services. This appendix covers the following topics:

Anonymous Access to Oracle Internet Directory

Typical users of directory naming (LDAP) require anonymous access to the Oracle Internet Directory for name lookup. If your Oracle Internet Directory software is upgraded to Oracle Internet Directory 11g, then it should be noted that the default setting for Oracle Internet Directory has changed. The default now is to disallow anonymous access to the directory. The directory administrator will need to configure the directory to enable anonymous binds after upgrading the directory to release 11g. In addition, the way anonymous binds are configured in Oracle Internet Directory has changed between Oracle Database 10g and Oracle Database 11g.

See Also:

Oracle Internet Directory Administrator's Guide for additional information about anonymous binds

Migrating a Non-default Listener to Oracle Database 11g Release 2 (11.2)

When migrating Oracle Database 11g Release 1 (11.1.0.7) to Oracle Database 11g Release 2 (11.2) in an Oracle Real Application Clusters environment, non-default listeners are not migrated by Oracle Net Services Configuration Assistant. To migrate the non-default listeners, use the following procedure:

  1. Use Oracle Database 11g Release 1 (11.1.0.7) Oracle Net Services Configuration Assistant to remove the non-default listeners.

  2. Use Oracle Database 11g Release 2 (11.2) Oracle Net Services Configuration Assistant to create the non-default listeners.

Removing the Listener Password

In Oracle Database 11g Release 2 (11.2), the password feature is being deprecated. This does not cause a loss of security because authentication is enforced through local operating system authentication. To migrate a listener that has a set password, do the following:

  1. Remove all PASSWORDS_listener_name entries from the listener.ora file.

  2. Reload the listener using the following command:

    lsnrctl reload listener_name
    

If remote administration of a listener is required, then use one of the following methods to connect to and administer the listener.

Client and Database Coexistence Issues

Clients and database servers require compatible releases of Oracle Net Services. For example, an Oracle9i client requires an installation of Oracle Net Services, and an Oracle9i database requires an installation of Oracle Net Services with the Oracle Net Listener.

Consider the following client-to-database connection issues before you decide if upgrading is appropriate for your environment:

Oracle9i Database Connections

Connect descriptors, created for connections to an Oracle9i database, identify a database by its service name with the SERVICE_NAME parameter.

A connect descriptor to an Oracle9i or Oracle8 database uses the parameter SERVICE_NAME, as shown in the following example:

sales= 
(DESCRIPTION= 
  (ADDRESS=(PROTOCOL=tcp)(HOST=sales-server)(PORT=1521))
  (CONNECT_DATA=
     (SERVICE_NAME=sales.us.example.com)))

Connect descriptors that are currently configured with the SID parameter can remain. However, to take advantage of new features, such as client load balancing and connect-time failover, Oracle recommends replacing SID with SERVICE_NAME.

To modify a connect descriptor to use SERVICE_NAME, use the Oracle Net Manager's compatibility mode.

See Also:

Oracle Database Net Services Administrator's Guide for additional information about database identification by SERVICE_NAME rather than SID

Oracle Names

Oracle Names is not supported as a centralized naming method. Because no new enhancements are being added to Oracle Names, consider using directory naming or upgrading an existing Oracle Names configuration to directory naming, as described in the Oracle Database Net Services Administrator's Guide.
