This manual describes how to upgrade from historical versions
|
|
|
|
|
|
of Berkeley DB (Berkeley DB 4.7 and older).
|
|
|
|
|
|
For information on upgrading newer releases
|
|
|
|
|
|
of the product (anything newer than DB 4.7), and on
|
|
|
|
|
|
building and installing Berkeley DB on all of the platforms it
|
|
|
|
|
|
officially supports, see the

<p>Each release of the Berkeley DB library has a major version number, a minor
|
|
|
|
|
|
version number, and a patch number.</p>
|
|
|
|
|
|
<p>The major version number changes only when major portions of the Berkeley DB
|
|
|
|
|
|
functionality have been changed. In this case, it may be necessary to
|
|
|
|
|
|
significantly modify applications in order to upgrade them to use the new
|
|
|
|
|
|
version of the library.</p>
|
|
|
|
|
|
<p>The minor version number changes when Berkeley DB interfaces have changed,
|
|
|
|
|
|
and the new release is not entirely backward-compatible with previous
|
|
|
|
|
|
releases. To upgrade applications to the new version, they must be
|
|
|
|
|
|
recompiled and potentially, minor modifications made (for example, the
|
|
|
|
|
|
order of arguments to a function might have changed).</p>
|
|
|
|
|
|
<p>The patch number changes on each release. If only the patch number has
|
|
|
|
|
|
changed in a release, applications do not need to be recompiled, and
|
|
|
|
|
|
they can be upgraded to the new version by installing the new version
|
|
|
|
|
|
of a shared library or by relinking the application to the new version
|
|
|
|
|
|
of a static library.</p>
|
|
|
|
|
|
<p>Internal Berkeley DB interfaces may change at any time and during any release,
|
|
|
|
|
|
without warning. This means that the library must be entirely recompiled
|
|
|
|
|
|
and reinstalled when upgrading to new releases of the library because
|
|
|
|
|
|
there is no guarantee that modules from the current version of the
|
|
|
|
|
|
library will interact correctly with modules from a previous release.</p>
|
|
|
|
|
|
<p>To retrieve the Berkeley DB version information, applications should use the
|
|
|
|
|
|
<a href="../api_reference/C/envversion.html" class="olink">DB_ENV->version()</a> function. In addition to the previous
|
|
|
|
|
|
information, the <a href="../api_reference/C/envversion.html" class="olink">DB_ENV->version()</a> function returns a string
|
|
|
|
|
|
encapsulating the version information, suitable for display to a user.</p>
