Naming Scheme for SQL/MX Releases

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

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

belonging to a given release of NonStop SQL/MX.

Starting in SQL/MX Release 2.1.0, 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 2.2)

are based on the product version identifier (for example, H22). 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.

Major and Incremental Releases

Major releases introduce significant new functionality. These releases occur less

frequently and usually require you to take specific action to use the new functionality,

such as perform an upgrade operation or alter existing applications.

Incremental releases introduce incremental changes and some new functionality,

which does not significantly affect existing applications.

In this manual, the SQL/MX releases are identified by major and incremental release

numbers, such as:

SQL/MX Release 2.1.2

(1) Major Release

(2) Incremental Release

(3) Maintenance Release
