Genezzo DB

The Genezzo DB is a prototype of a micro kernel style SQL database server. Genezzo DB runs efficiently in a distributed fashion across dynamic clusters of servers. Developer productivity is enhanced through a variety of extensible and tunable aspects of Genezzo:

  • Data storage
  • Data types
  • Access, query and indexing methods
  • Application interfaces
  • SQL Skins

As an open source project based on the foundation of over 50 years of experience with enterprise class applications and relational databases, Genezzo is designed to be able to adapt to a wide variety of enterprise software and scientific computing demands.

 

Dependencies

Genezzo runs on any system which runs Perl version 5.8 or greater. Perl runs on many platforms, and it is usually part of the default installation on most operating systems, including Linux, FreeBSD, Mac OS X 10.3+, Sun Solaris, IBM AIX, etc. The major exception is Microsoft Windows. Additional instructions for installing Perl on Windows are listed here. General information about obtaining Perl is available at Get Perl. In addition, Genezzo requires the Parse::RecDescent parser module.

Instructions for Perl Users

Genezzo is a standard Perl package available on CPAN. If Perl is properly configured on your machine you can use the interactive cpan command line tool to "install Genezzo". This tool will resolve all packaging dependencies and automatically install Parse::RecDescent as well.

Instructions for Unix Users

If you are unable or unwilling to use the cpan tool, you can manually install Parse::RecDescent and Genezzo using the download links on these pages. The packages are distributed as compressed tarballs. More detailed instructions are available here (they may exist on your system as man pages under "man perlmodinstall"). After you uncompress and unpack the tarballs, go into the new Parse-RecDescent directory and type:

  • perl Makefile.PL
  • make test
If the test succeeds, type make install (while you are still in the new directory) to install the package. After installing Parse-RecDescent, follow a similar procedure for Genezzo.
Note: installing these packages may require super-user privileges.

Instructions for Windows Users

Perl is available for Windows under the Cygwin or ActiveState distributions. Cygwin is a large package which contains a number of standard Linux tools in addition to Perl, while the ActiveState distribution is only a Perl toolset. If you install Cygwin, you should be able to follow instructions for Unix users afterward. More detailed instructions for both Cygwin and ActiveState module installation are here The basic instructions for ActiveState are as follows:

  • Download and install a copy of Perl for Windows. Registration is optional and can be skipped. I use the MSI installation but I don't think it makes a difference for only one machine. I usually override the default installation folder location of C:\perl and put it in c:\program files\perl with all the other programs.
  • Download the additional Parse::RecDescent module from CPAN. Extract the components from the compressed TAR file. I used WinZip to extract the compressed tar files, which can be downloaded here. Bring up a command line window (also called the DOS window) by clicking in Start/Run and typing in cmd. Change directory to your Parse-RecDescent folder, and build the Makefile by typing perl Makefile.pl.
  • You'll need the nmake utility, available at http://download.microsoft.com/download/vc15/Patch/1.52/W95/EN-US/nmake15.exe or dmake, available on CPAN at http://search.cpan.org/dist/dmake/. You might need to copy this utility into your Perl Bin folder. For me this was C:\program files\Perl\bin.
  • Build Parse-RecDescent by typing nmake in the Parse-RecDescent folder. Ignore the error about the missing errors file. Install the Parse module by typing nmake install.
  • Download the latest version of Genezzo. Extract the Genezzo components from the Genezzo compressed TAR file -- be sure to extract all files. Create the Makefile by typing perl Makefile.pl. Build Genezzo by typing nmake. Test your new build of Genezzo by typing nmake test (this is the fun part, watching Genezzo run through its extensive self-test sequence). If you experience any errors here please report them to the Genezzo team via email. This test takes between 2 to 5 minutes depending on the speed of your PC. Now install Genezzo by typing nmake install.
