Apache Derby is a pure Java relational database engine using standard SQL and JDBC as its APIs. More information about Derby can be found on the Apache web site. Derby functionality includes:

• Embedded engine with JDBC drivers
• Network Server
• Network client JDBC drivers
• Command line tools: ij (SQL scripting), dblook (schema dump) and sysinfo (system info)

Java and JDBC versions supported:

• Java SE 1.4 and higher with JDBC 2.1, 3.0, 4.0 and 4.1
• Java ME CDC/Foundation Profile 1.1 with JSR-169 JDBC Optional Package for CDC/Foundation Profile.

This is a bug fix release. No new features were added.

The following issues are addressed by Derby release 10.8.2.2. These issues are not addressed in the preceding 10.8.1.2 release.

Compared with the previous release (10.8.1.2), Derby release 10.8.2.2 introduces the following new features and incompatibilities. These merit your special attention.

It is essential that you verify the integrity of the downloaded files using the PGP and MD5 signatures. MD5 verification ensures the file was not corrupted during the download process. PGP verification ensures that the file came from a certain person.

The PGP signatures can be verified using PGP or GPG. First download the Apache Derby KEYS as well as the asc signature file for the particular distribution. It is important that you get these files from the ultimate trusted source - the main ASF distribution site, rather than from a mirror. Then verify the signatures using ...

% pgpk -a KEYS
% pgpv db-derby-X.Y.tar.gz.asc

or

% pgp -ka KEYS
% pgp db-derby-X.Y.tar.gz.asc

or

% gpg --import KEYS
% gpg --verify db-derby-X.Y.tar.gz.asc

To verify the MD5 signature on the files, you need to use a program called md5 or md5sum, which is included in many unix distributions. It is also available as part of GNU Textutils. Windows users can get binary md5 programs from here, here, or here.

We strongly recommend that you verify your downloads with both PGP and MD5.
