Oracle NoSQL Database is a distributed key-value store capable of scaling horizontally to handle very large amounts of data.

This Release

This is release 22.3.16 of Oracle NoSQL Database.

We strongly recommend that users of earlier versions upgrade to this release. For a complete listing of all the changes made to Oracle NoSQL Database for this release, including all bug fixes, see the change log.

Supported Java Versions

The Oracle NoSQL Database server is compatible with Java SE 8 (64-bit), and the client is compatible with Java SE 8. Both the client and the server require at least Java SE 8, and should work with more recent Java SE versions. The client and server have been tested and certified against Oracle Java SE and OpenJDK 17.0.2. We encourage you to upgrade to the latest Java release to take advantage of the latest bug fixes and performance improvements. We expect to certify Oracle NoSQL Database with more recent Java versions in a future release.

Attempting to use this release with a version of Java earlier than the required version will produce an error message similar to:
Exception in thread "main" java.lang.UnsupportedClassVersionError:
    oracle/kv/impl/util/KVStoreMain : Unsupported major.minor version 52.0

Requiring Java 11 in 2023

We expect to require Java SE 11 or later for both the client and the server starting with the first quarterly release in 2023. Please plan to switch to a Java 11 or later runtime in preparation for that upcoming release. Since standard support for the Java 11 long term support (LTS) release is only available through September 2023, we recommend upgrading to Java 17, which is the latest LTS release.

Product Upgrade Policy

Release 22.3 supports upgrades from releases 22.1 and 22.2, and from releases for the prior two calendar years. To upgrade a store directly to the current release, the store must be running release 20.1 or later.

If you have a store running a 19.x release, we recommend that you upgrade it to the current release by first upgrading to the 21.2 or 20.3 release (or another 21.x or 20.x release) and then upgrading from that to the current release. If you have a store running an 18.x release, we recommend that you upgrade to the 20.3 release (or another 20.x release) and then upgrade from that to the current release. If you have a store running a 4.x release, we recommend that you first upgrade to the 19.5 release (or another 19.x release) and then follow our recommendations for upgrading from 19.x. If you have a store running a release earlier than the 4.x release and you are an Enterprise Edition user, please contact support. If you are a Community Edition user with this issue, please post a question to the NoSQL Database Discussions forum on Oracle Communities.
