In this section the Ingres II Relational Database
Management System is introduced and you come to know how
to get it. Let us start with an important fact: there are two different types
of Ingres.
The original one, which was designed and developed in the seventies by a
research group led by Michael Stonebraker at the University of California,
Berkeley, was the first open source relational database management system:
it was free to use and distribute, source code included.
In fact, it is still free software, although its
development stopped in 1989.
Its last version (version 8.9) made it into some Linux distributions as well.
If you are interested in it, you can download it from, say, the SuSE site.
The packages are: In 1979, with the foundation of Relational Technology, the career
of Commercial Ingres started.
Since 1995 it has been distributed by Computer Associates.
Its latest version is Ingres II 2.0.
This HOWTO deals with the installation of this type of
Ingres. Ingres, being commercial software,
is not free to use.
However, CA, like most RDBMS vendors,
offers a free version of it
(the Software Development Kit) to everyone who is interested in learning
Ingres.
The SDK has two variants, one for Windows NT and one
for Linux.
These variants are not quite the same as far as the included components
are concerned.
Obviously, we are engaged in installing the SDK for
Linux here.
This contains the following elements: Intelligent DBMS: the database engine. Internet Commerce Enabled (ICE):
Ingres' propriatery CGI
solution to connect a database to the Web. Enhanced Security: the tool supporting mandatory access
control. C2 Security Auditing: the possibility of C2 level auditing. Terminal Monitors: forms-based and command line
SQL interfaces. Querying and Reporting Tools: forms-based querying,
report-writing and report-running tools plus a forms editor. Querying and Reporting Runtime: like the previous one,
but without the forms editor. Vision Pro: integrated, forms-based development environment
with a code generator. Embedded SQL Precompilers: precompilers for
embedding SQL statements in 3GL
applications.
Supported languages are: C, C++, COBOL, and Fortran.
You can order a free copy of the
Ingres SDK CD on
http://www.cai.com/registration/cd_ingres.htm. Remember that you are not allowed to use the
SDK in a business environment.
It is for evaluating Ingres and prototyping
applications only. The SDK CD contains both the
Windows NT and the Linux versions of the Software Development Kit.
You can find the Linux files in the following directories: /doc: the manuals in
PDF format, together with the Linux version
of Acrobat Reader
(linux-ar-40.tar.gz).
The installer will not copy the documentation to hard disk.
These manuals are also available on
http://www.cai.com/products/ingres/documentation_set.htm.
I will reference some of them later in this document. /int_lnx:
this directory contains ingres.tar,
the tarball to be installed.
ingres.tar can be installed directly
from the CD or you can copy it to hard disk first.
Do not forget to read the Readme file in the
root directory on the CD. In February 2000 Computer Associates announced the general
availability of Ingres II 2.0 for Linux.
Besides the components found in the SDK,
the full edition contains more modules, such as: Net: this component makes possible for
Ingres utilities and user applications
to access databases residing on different installations. Replicator: support for replication functions. Star: for handling distributed databases. Enterprise Access: communication with different database
management systems and other, non-relational data sources
(used to be called Gateways). Protocol Bridge: for communicating with clients on different
types of networks. Spatial Object Library: for handling two-dimensional spatial
objects.
The CD, besides the /doc and
/int_lnx directories that are common
with the SDK, contains install.sh, the general
Ingres installer and its files.
More on install.sh later, in subsection
Starting the Installation Program. At last, let me note that the Linux version of CA's
Unicenter TNG Framework also includes
Ingres as its embedded database management system.
For this reason, knowing Ingres may come in
handy when using Unicenter, too.
You can order a free Unicenter TNG Framework CD on
