# Welcome page, Custom Install Mode

Welcome to Net8 Configuration Assistant in Custom installation mode. You can configure basic elements of the network, including:

### Directory Server Access configuration

Select this option to configure access to a LDAP-compliant directory server, if you plan to use:

- Directory naming to centrally administer connect identifiers

- Enterprise user security for use with Oracle Advanced Security

### Listener configuration (Server Only)

Select this option to create a listener with one or more protocol addresses. The listener is a process on the server that receives and responds to client connection requests for a database. Clients using connect descriptors configured with the same protocol addresses can send a connection request to the listener.

| Note: This option is not available on clients.

### Naming Methods configuration

Select this option to configure naming methods. When an end user connects to a database service, a connect string that identifies the service through a simple name, called a connect identifier, is used. A connect identifier can be the actual name of the service or a net service name. The connect identifier is resolved to a connect descriptor, which contains the network location and identification of the service, by a naming method. You can configure this computer to resolve connect identifiers using any of the following methods:

- Local naming (Local)

- Directory naming (Directory)
- Oracle Names (Oracle Names)
- Host naming (Host Name)
- Novell Directory Services (NDS)
- Network Information Service (Sun NIS)
- Cell Directory Service (DCE CDS)

Additionally, if the local naming method is selected on the client, you are prompted to configure connect descriptors in a client-side tnsnames.ora file.

### Perform a typical configuration

Select this option to configure the following:

- Default network domain in the sqlnet.ora file

  The computer's network domain is automatically selected as the default domain. This domain is appended to any unqualified net service name given in the connect string, and then compared to net service names stored in a tnsnames.ora file or Oracle Names server. For example, if the client `tnsnames.ora` file contains a net service name of `sales.us.acme.com`, the user can enter the following connect string:

  `CONNECT scott/tiger@sales`

  `sales` gets searched as `sales.us.acme.com`.

- Two net service names in the tnsnames.ora file

  One net service name will automatically be established for connections to external procedures.

  Net8 Configuration Assistant will prompt you to configure a net service name for a client connection to the database.

- Directory access configuration

  You are prompted to configure access to a directory server.

- (Server Only) Two default listener protocol addresses in the listener.ora file

  One address will use TCP/IP on port 1521 and the other will use IPC for client connections to the Oracle database.
