Naming Scheme for SQL/MX Releases

NonStop SQL/MX contains many individual products, which are identified by

T-numbers. A SQL/MX release name identifies a set of SQL/MX products as belonging

to a given release of NonStop SQL/MX.

Each SQL/MX release is identified by a three-part release identifier:

1. The first number indicates a

major release, which introduces major new

functionality and a new SQL version.

2. The second number indicates an incremental release, which introduces an

incremental change and some new functionality.

3. The third number indicates a

maintenance release, which introduces bug fixes and

minimal new functionality.

The migration risk increases from maintenance to major releases because major

releases introduce significant new functionality that makes fallback more difficult, if

implemented.

The first and second levels of the release name (for example, SQL/MX Release 3.0)

are based on the product version identifier (for example, H30). Major and incremental

releases typically change the product version of NonStop SQL/MX. Maintenance

releases and time-critical fixes (TCFs) do not change the product version of NonStop

SQL/MX.
