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
- using directory naming or
- migrating an existing Oracle Names configuration to directory naming.
Oracle Internet Directory
The Oracle Internet Directory (OID) was introduced with Oracle8i. OID replaced Oracle Names used in prior database releases since it gives users a way to connect to an Oracle Server without having a client-side configuration file.
OID is an LDAP (Lightweight Directory Access Protocol) directory and so it supports Oracle Net and other LDAP-enabled protocols.
This module investigates Oracle Names and how the Names utility is used to manage a distributed network of computers. The topics include:
- A conceptual overview of Oracle Names
- Proper use of Oracle Names
- Storing the configuration file for Oracle Names
- 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
- 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:
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.
After completing this module, you will be able to:
- Describe the architecture of Oracle Names
- Describe how a request is resolved through Oracle Names
- Explain when it is not appropriate to use Oracle Names
- Store the overall topology
- Use the Names control utility
- Use the basic names control commands
Let us begin our tour with a conceptual overview of Oracle Names.
