Who Should Run this Installer

Oracle Client software is used by a variety of applications software such as BrioQuery, COEUS, and Roles. If the installation instructions for any application to be installed on your computer list Oracle as a requirement or prerequisite, then you should install the Oracle 9i Client Core first.

If none of the applications you plan to install indicate that Oracle is required, there is no need for you to download the Oracle 9i Client.

Components Included

This installer contains the following components:

  • SQL*Net
  • ASO (Advanced Security Option)
  • Oracle ODBC drivers
  • SQL*Plus

The installer also includes MITAnsSeedGenerator, a Java program that generates a unique random seed for SQLNET.CRYPTO_SEED value. This program is deleted upon completion of the installation.

Updating tnsnames.ora

tnsnames.ora is an MIT file maintained by the Database Services Team and populated in LDAP v3 OID server When Oracle Client Software is invoked on the desktop, it resolves host names first by looking in OID. Its fallback is to the local tnsnames.ora file on the desktop.

IS&T recommends that you update your local tnsnames.ora file periodically. You can use the procedure below to update the tnsnames.ora file on your PC. You need to have a direct connection to MITnet or access to MITnet via an ISP to complete this procedure or Tether (which is now retired, please see Tether Service Retired for more info).

  1. Download the TNSNames Updater from the MIT Software Distribution site to your Windows computer. (certificates required)
  2. Double-click on the MIT-tnsnames-updater-2.0.exe to begin the installation.
  3. Follow the on-screen instructions.
  4. When prompted, accept the default directory, FilesOracleora92 etworkAdmin, as your destination directory.
    Result: At the completion of the installation, a message appears stating that the installation was successful.
