Distributions

Use the links below to download a distribution of Apache Derby. You should always verify the integrity of distribution files downloaded from a mirror.

There are four different distributions:

  • bin distribution - contains the documentation, javadoc, and jar files for Derby.
  • lib distribution - contains only the jar files for Derby.
  • lib-debug distribution - contains jar files for Derby with source line numbers.
  • src distribution - contains the Derby source tree at the point which the binaries were built.

Issues

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.


Note for DERBY-5395

Summary of Change

Now, only the database owner may view several diagnostic VTIs: syscs_diag.statement_cache, syscs_diag.transaction_table, syscs_diag.error_log_reader( ), and syscs_diag.statement_duration().

Symptoms Seen by Applications Affected by Change

Previously in a database with SQL authorization enabled, any user could select from those diagnostic VTIs. Now only the database owner can.

Incompatibilities with Previous Release

Application designers should ensure that only the database owner selects from these VTIs. For most applications this should not be a problem since the VTIs are intended to be used in production only as technical support tools.

Rationale for Change

These VTIs reveal sensitive information which only authorized persons should see.

Application Changes Required

Table functions with definer's rights can be used to grant other users access to the information in these VTIs. For instance, the following technique can be used to let ordinary users view the non-sensitive data in syscs_diag.statement_cache:

First, create a static Java method which selects only the non-sensitive columns:

import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;

public class SafeCacheViewer
{
    public  static  ResultSet   safeCacheViewer()   throws SQLException
    {
        return DriverManager.getConnection( "jdbc:default:connection" ).prepareStatement
            ( "select id, schemaName, valid, compiled_at from syscs_diag.statement_cache" ).executeQuery();
    }
}

Then the database owner should register the method as a table function enjoying definer's rights, and grant EXECUTE privilege on it to PUBLIC:

create function safeCacheViewer()
returns table
(
    id char( 36 ),
    schemaName varchar( 128 ),
    valid boolean,
    compiled_at timestamp
)
language java parameter style derby_jdbc_result_set reads sql data
external security definer
external name 'SafeCacheViewer.safeCacheViewer';

grant execute on function safeCacheViewer to public;

Finally, other users can select data from the table function as follows (here test_dbo is the schema of the database owner):

select * from table( test_dbo.safeCacheViewer() ) s;

Build Environment

Derby release 10.8.2.2 was built using the following environment:

  • Branch - Source code came from the 10.8 branch.
  • Machine - Windows XP Professional Version 2002 Service Pack 3
  • Ant - Apache Ant version 1.7.0 compiled on December 13 2006.
  • JDK 1.4 - Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2) Classic VM (build 1.4.2, J2RE 1.4.2 IBM Windows 32 build cn142ifx-20110211 (SR13 FP8+PM31983)).
  • Java 6 - Java(TM) SE Runtime Environment (build pwi3260sr9fp1-2011-0208_03(SR9 FP1) IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Windows XP x86-32 jvmwi3260sr9-20110203_74623).
  • Compiler - The 1.6.0-b105 javac was used to compile all classes.
  • JSR 169 - Java ME support was built using libraries from IBM's j9 jvm from WEME 6.2.

Verifying Releases

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.
