Oracle7 Administrator's Reference for UNIX
Installing SQL*Net Version 2
1. Read Understanding SQL*Net to get a basic understanding of the product and how to plan your community and configure SQL*Net.
2. Review this chapter to learn the UNIX filenames and locations of the configuration, log, and trace files and related utilities. Be familiar with UNIX operating system security issues, such as operating system authorized logins.
3. Make sure your system satisfies all hardware and software requirements listed in the Oracle7 Installation Guide for your platform.
4. Install the Operating System Networking Software, such TCP/IP, SPX/IPX, or DECnet. The underlying protocol must be installed and functioning at the time SQL*Net is installed.
Attention: You must install and test the runtime and compile time components of the operating system protocol layer (such as DECnet and DECnet operating system libraries) before you install SQL*Net and Oracle Server. On some operating systems these components are packaged or sold separately.
5. Perform the SQL*Net steps listed in Chapter 3 of the Oracle7 Installation Guide for your platform, in the section "Prepare to Install SQL*Net Version 2 Products."
6. Install the Oracle Server for a local database and SQL*Net V2.
7. Link SQL*Net V2 to the operating system networking software.
Attention: If you do not link the operating system networking components and the protocol adapter to your client or server, you cannot configure the Oracle Server or install SQL*Net protocols. You also may not be able to start the Oracle database.
When you link as part of the installation, link the instance or client to the object code that constitutes the SQL*Net layer and to the code that provides the operating system protocol layer. If you install another protocol, you must relink all executables.
8. Start the Oracle Server process on the server only.
9. Start the listener Process on the server.
Before SQL*Net clients can connect to the server, the DBA (or anyone with the necessary privileges) must start the listener process on the host system. A listener process listens for the connection requests from the clients and directs them to the database with the proper environment.
Use one of the following methods to start the listener process:
- Make an entry in the UNIX startup file to automatically start up the listener process with the control utility when UNIX is booted up, as described in your UNIX system administration documentation. The startup file is usually in /etc/rc or in an /etc/rcN.d directory.
- Use the control utility that controls and monitors the server process manually.
