Introduction to configuring Oracle Names

Oracle Names has been deprecated since Oracle 9i

In future releases, Oracle Names will not be supported as a centralized naming method. Because no new enhancements are being added to Oracle Names, consider
  1. using directory naming or
  2. migrating an existing Oracle Names configuration to directory naming.
This module investigates Oracle Names and how the Names utility is used to manage a distributed network of computers. The topics include:
  1. A conceptual overview of Oracle Names
  2. Proper use of Oracle Names
  3. Storing the configuration file for Oracle Names
  4. An overview of the Names Control utility

    Desupport of Oracle Names Control Utility for Oracle Net Services

    The Oracle Names Control Utility is desupported and has not been available starting with Oracle Database 10g. This includes all the related control utility commands. Oracle Database clients cannot use a Names Server to resolve connect strings. Migrate your applications to Oracle Internet Directory with LDAP directory naming
  5. Starting and stopping the Names server



Deprecated and Desupported Parameters

In Oracle Database 12c, some database parameters are deprecated and desupported, or removed. To obtain a current list of deprecated parameters, run the following query in SQL*Plus:
SQL> SELECT name from v$parameter 
         WHERE isdeprecated = 'TRUE' ORDER BY name;
The query returns a list of the deprecated parameters as of the date and time that you run it. The following example shows the query results that appear:
active_instance_count
background_dump_dest
buffer_pool_keep
buffer_pool_recycle
commit_write
cursor_space_for_time
fast_start_io_target
global_context_pool_size
instance_groups
lock_name_space
log_archive_start
max_enabled_roles
parallel_automatic_tuning
parallel_io_cap_enabled
parallel_server
parallel_server_instances
plsql_v2_compatibility
remote_os_authent
resource_manager_cpu_allocation
sec_case_sensitive_logon
serial_reuse
sql_trace
standby_archive_dest
user_dump_dest

Desupport of Oracle Enterprise Manager Database Control

Starting with Oracle Database 12c, Oracle Enterprise Manager Database Control is desupported and is no longer available. Oracle introduces Oracle Enterprise Manager Database Express (Oracle EM Express) as a replacement. Oracle EM Express is installed when you upgrade to Oracle Database 12c.

Oracle Names History

Oracle Names is not required by any Oracle environment and was a management tool that simplified the maintenance of the Net8 parameter files (now Oracle Network Services) and database links.

Learning objectives

After completing this module, you will be able to:
  1. Describe the architecture of Oracle Names
  2. Describe how a request is resolved through Oracle Names
  3. Explain when it is not appropriate to use Oracle Names
  4. Store the overall topology
  5. Use the Names control utility
  6. Use the basic names control commands
Let us begin our tour with a conceptual overview of Oracle Names.
