A Features Not Supported in this Release

This appendix describes features no longer supported by Oracle Net Services.

This appendix contains these topics:

Overview of Unsupported Features

In an effort to streamline configuration decisions for the Internet, the following subsections describe the features and the configuration file that are no longer being supported:

Oracle Names

Oracle Names is no longer supported as a naming method in Oracle Database 10g . You must migrate to directory naming.

See Also:

Oracle Net Services Administrator's Guide for information about migrating to directory naming

Identix and SecurID Authentication Methods

If you are using Identix or SecurID authentication methods, provided by Oracle Advanced Security, Oracle Corporation recommends migrating to one of the following authentication methods:

Novell Directory Services (NDS) External Naming and NDS Authentication

Support for NDS as an authentication method and as an external naming method is no longer supported. If you are using NDS as an external naming method, Oracle Corporation recommends using directory naming instead.


Net8 OPEN, which provided an application program interface (API) that enabled programmers to develop both database and non-database applications, is no longer supported.

protocol.ora File

The protocol.ora file is no longer supported.

Parameters in the protocol.ora file have been merged into the sqlnet.ora file. These parameters enable you to configure access control to the database, as well as no delays in TCP/IP buffer flushing. These parameters include:

If you have a protocol.ora file in the $ORACLE_HOME/network/admin directory on UNIX, and the ORACLE_HOME\network\admin directory on Windows operating systems, Oracle Net Manager, when first started, automatically merges the protocol.ora parameters into the sqlnet.ora file.

There may be operating system-specific parameters in protocol.ora that are node specific. For this reason, Oracle Corporation recommends not sharing sqlnet.ora with other nodes after merging or adding these parameters.

Prespawned Dedicated Servers

Prespawned dedicated server processes are no longer supported. Instead, configure shared server to improve scalability and system resource usage.


Protocol addresses using the SPX or LU6.2 protocol must be replaced. Oracle Net provides support for the following network protocols:

  • TCP/IP

  • TCP/IP with SSL

  • Named Pipes

  • SDP

    "Protocol Parameters" for protocol parameter configuration

Unsupported Parameters

Table A-1 describes the networking parameters no longer supported.

Table A-1 Unsupported Networking Parameters

File Parameter Description Last Supported Release
tnsnames.ora COMMUNITY The parameter was a required part of all network service addresses. Thus, it appears anywhere you might find an address (for example, local naming and listener configuration files). 8.0
sqlnet.ora AUTOMATIC_IPC This parameter was used to force sessions through IPC addresses. Due to performance issues, this parameter has been removed. Configure an IPC address instead. 8.0
sqlnet.ora NAMES.DEFAULT_ZONE This parameter used to be included in profiles as slight variants of the NAMES.DEFAULT_DOMAIN parameter. 8.0
sqlnet.ora NAMES.NDS.NAME.CONTEXT This parameter was used to configure naming contexts for NDS external naming. 8.1
sqlnet.ora OSS.SOURCE_MY_WALLET This parameter's name has changed to WALLET_LOCATION. 8.1
sqlnet.ora SQLNET.CRYPTO_SEED This parameter was used to seed a random number generator for Oracle Advanced Security. In 10i, Oracle Advanced Security uses a random number generator that does not to require a user-supplied seed value. 9.2




These parameters supported the Identix authentication method. 8.1
listener.ora CONNECT_TIMEOUT This parameter specified the amount of time that the listener waited for a client's request after the transport connection had been established. Use the INBOUND_CONNECT_TIMEOUT_listener_name parameter. 8.1
listener.ora PRESPAWN_DESC



These parameters were used for prespawned dedicated server configuration. Prespawned dedicated servers are no longer supported. Use shared server instead. 8.1
listener.ora USE_PLUG_AND_PLAY_listener_name This parameter instructed the listener to register database information with an Oracle Names server during startup. 8.1
names.ora All parameters Oracle Names is no longer supported. 9.2

Unsupported Control Utility Commands

Table A-2 describes the control utility commands not supported in release 9.0.

Table A-2 Unsupported Network Control Utility Commands

Control Utility Commands Description Last Supported Release
Oracle Names Control Utility All commands Oracle Names is no longer supported. 9.2
Listener Control Utility DBSNMP_START



These commands controlled the Oracle Intelligent Agent for use with Oracle Enterprise Manager. You can now control the Oracle Intelligent Agent through the Oracle Enterprise Manager Console. 8.1
Listener Control Utility SET CONNECT_TIMEOUT


These commands specified the amount of time that the listener waited for a client's request after the transport connection had been established. 8.1
Listener Control Utility SET USE_PLUGANDPLAY


These commands instructed the listener to register database information with an Oracle Names server. 8.1
