Selecting Net8 Configuration Methods

This chapter describes the Net8 client configuration methods available during installation. You must understand these methods before performing an installation.

Specific topics discussed are:

Understanding Your Methods Before Installation

Oracle Universal Installer provides several methods for configuring your Net8 client/server environment during installation.

The method to select during installation depends upon:

You must understand these methods before you begin installation. By reviewing the information in this chapter, you can ensure that you configure a network environment that best matches your needs from the beginning.

Net8 components are installed through several installation types. Review the installation types in this table to identify how much user input is required for network configuration during installation. The "X" indicates whether you are prompted to provide no, minimal, or extensive input during installation. Then, see the remaining sections of this chapter for specific details on what information is automatically created for you, and what information you must manually provide.

Selecting a Net8 Configuration Method

Net8 Configuration Assistant is a tool that enables you to configure your network environment to enable Oracle clients to connect to an Oracle8i database. Net8 Configuration Assistant can be automatically started from Oracle Universal Installer through most installation types or manually started as a standalone tool.


Note:

This chapter describes running Net8 Configuration Assistant from within Oracle Universal Installer. See the Net8 Administrator's Guide or the Net8 Configuration Assistant online help for information on running Net8 Configuration Assistant in standalone mode. See Chapter 2, "Database Tools Overview", of the Oracle8i Client Administrator's Guide for Windows for instructions on starting this tool in standalone mode. 


Depending on the installation type selected, Net8 Configuration Assistant configures your network in either of two ways:

Configuration consists of creating and modifying a series of network files located in the ORACLE_BASE\ORACLE_HOME\NETWORK\ADMIN directory.

Client Network Configuration

The type of network configurations created with the client installation types and the amount of user input required are described below. Review the selections below and identify the network configuration that best matches your requirements and network configuration expertise:

If You Select These Installation Types...  Then... 

Oracle8i Client

  • Administrator

  • Programmer

  • Application User

 

Net8 Configuration Assistant first prompts you to select one of the following methods by which to configure access to your Oracle8i database:

  • Directory naming

 

 

  • A directory server

 
  • Local naming

 

 

 

  • A net service name enables you to make client connections to the Oracle8i database

 

 

Depending on what you select, you are prompted to provide additional information. 

 

Net8 Configuration Assistant then automatically creates your Net8 client environment by configuring information in the following files: 

 

  • LDAP.ORA, if the directory naming method was selected above

 

 

 

  • Configures directory server access by identifying the directory server type. It may also identify the directory location and the administrative context from which the client can look up net service names.

 

 

  • TNSNAMES.ORA

 

 

 

  • Configures a net service name, if a local naming method was selected above

 

 

  • SQLNET.ORA

 

 

 

  • Configures the client's domain as the default domain (the domain in which your computer is located). This domain is automatically appended to any unqualified net service name given in the connect string.

 

 

 

 

Oracle8i Client

  • Custom (and then select Net8 Client)

 

Net8 Configuration Assistant first prompts you to:

  • Complete directory server access configuration, including entering a directory server type and location and administrative context from which the client can look up, create, and modify net service names1

  • Select the naming method to use to connect to databases. For example, selecting the local naming method enables the TNSNAMES.ORA file to be used. Depending on your selection, you are prompted for additional information. For the local naming method, you are prompted to enter a net service name, a database SID, and a networking protocol to use.

Net8 Configuration Assistant then automatically creates your Net8 client environment by configuring information in the following files:

  • SQLNET.ORA

 

 

 

  • Configures the client to request operating system authenticated connections (OPS$)

  • Configures the client's domain as the default domain (the domain in which your computer is located). This domain is automatically appended to any unqualified name.

  • Configures the naming methods the client uses to resolve a name to a connect descriptor

 

 

  • TNSNAMES.ORA

 

 

 

  • Configures a net service name, if the local naming method was selected above to connect to your Oracle8i database

 

 

  • LDAP.ORA, if directory naming was selected above

 

 

 

  • Configures directory server access by identifying the directory server type. It may also identify the directory location and the administrative context.

 
1 You are prompted for this information if you have never configured this Oracle home for directory server access.
