Overview of Release Numbers

There is a release numbering scheme for TimesTen releases. This scheme is relevant when discussing upgrades. For example, for a given release, a.b.c.d.e:

• a indicates the first part of the major release.

• b indicates the second part of the major release.

• c indicates the patch set.

• d indicates the patch level within the patch set.

• e is reserved.

Important considerations:

• Releases within the same major release (a.b) are binary compatible. If a release is binary compatible, you do not have to recreate the database for the upgrade (or downgrade).

• Releases with a different major release are not binary compatible. In this case, you must recreate the database. See "Migrating a Database" for details.

As an example, for the 22.1.1.25.0 release:

• The first two numbers of the five-place release number (22.1) indicate the major release.

• The third number of the five-place release number (1) indicates the patch set. For example, 22.1.1.25.0 is binary compatible with 22.1.1.26.0 because the first two digits in the five-place release number (22 and 1) are the same.

• The fourth number of the five-place release number (1) indicates the patch level within the patch set. 22.1.1.26.0 is the first patch level within patch set two.

• The fifth number of the five-place release number (0) is reserved.
