Use the Oracle installer to install the Client Software
Run Oracle Installer
Installing the Oracle Net Services client software is relatively straightforward. You simply run setup.exe from the Oracle8 client CD-ROM. The following Slide Show illustrates the steps involved in the installation.
To use the main Oracle installer screen (the final illustration in the oracle-client above), simply select an item (or group of items by Ctrl-clicking). Choose items from the panel on the right and click the Remove button to uninstall them.
Choose items from the panel on the left and click the Install button to proceed with the installation. The Oracle installer will then analyze product dependencies and install the desired components.
In most cases you would choose Oracle8 (Oracle Net Services) over SQL*Plus client software, but both will function properly.
You can run an Oracle8 client to access Oracle7 databases, and establish connections to any Oracle listener, even a SQL*Net version 1 listener. You can also install an Oracle version 7 SQL*Net client that will connect successfully with a Oracle Net Services listener.
Unfortunately, it is not possible to use a third-party tool to automatically distribute the Oracle8 client software.
You must install the Oracle8 client software individually on each client PC. This is because the Oracle8 client will make entries into the Registry for the PC, and it is difficult, if not impossible, to successfully distribute registry entries to a large number of PCs.
For large sites with thousands of PCs, you should never install the Oracle Net Services administrator tools such as SQL*Net Easy or Oracle Net Services Assistant.
Such restraint will enable you to maintain uniformity across all PC clients.
Having installed the Oracle Net Services client, you still need to create and test a tnsnames.ora file. The next lesson discusses the best strategy for doing so.
