Key Features

  • Smart LOB (SLOB) Support
  • Kerberos Enhancements – This feature enables single sign on (SSO) support using Kerberos authentication on UNIX clients: Solaris, MacOS, AIX and HP-UX. This support already exists for Linux clients (JDBC, CLI, and ODBC) and Windows clients (JDBC, CLI, ODBC, and .NET). This feature allows centralized management of user accounts and credentials using Kerberos.

  • Now supported on AIX 7.2
  • Now supported on Apple OSX 10.11

  • Support for row size up to 1MB and Maximum Response Buffer Size up to 16MB
  • Added support for Windows Session character sets supported in past DBS releases
  • Allow support for multiple driver instances from 16.00 onward:
    • Starting with ODBC Driver for Teradata 16.00, you can have multiple versions of the ODBC Driver installed on one machine.
    • The default driver name has been changed from Teradata to Teradata Database ODBC Driver XX.YY, where XX.YY is the version of the ODBC Driver.
