==Licensing==

Berkeley DB V2.0 and higher is available under a [[dual license]]:

# Oracle commercial license <ref>{{cite web|url=http://www.oracle.com/technetwork/database/database-technologies/berkeleydb/downloads/index.html|title=Download, license and sales information|date=Nov 30, 2017}}</ref>
# The [[GNU Affero General Public License|GNU AGPL v3]].<ref>{{cite web|url=https://oss.oracle.com/pipermail/bdb/2013-June/000056.html|title=Major Release: Berkeley DB 12gR1 (12.1.6.0)|date=June 10, 2013|access-date=July 15, 2013}}</ref>

Switching the open source license in 2013 from the [https://opensource.org/licenses/Sleepycat Sleepycat license] to the AGPL had a major effect on open source software. Since BDB is a library, any application linking to it must be under an AGPL-compatible license. Many open source applications and all closed source applications would need to be relicensed to become AGPL-compatible, which was not acceptable to many developers and open source operating systems. By 2013 there were many alternatives to BDB, and [[Debian|Debian Linux]] was typical in their decision to completely phase out Berkeley DB, with a preference for the [[Lightning Memory-Mapped Database]] (LMDB).<ref>{{cite mailing list | url=https://lists.debian.org/debian-devel/2014/06/msg00338.html | title=New project goal: Get rid of Berkeley DB (post jessie) | mailing-list=debian-devel | date=June 19, 2014 | author=Ondřej Surý |publisher=[[Debian]]}}</ref>
