PowerHouse CGI for Linux

[Whittall, Conrad]

Greetings listers!

This is to inform you that the very first Cognos component for Linux is now
available. We are pleased to announce the immediate availability the
PowerHouse CGI component of PowerHouse Web for Intel-based Linux servers.

What does this mean? Well, PowerHouse CGI (PHCGI) is the only component of
PowerHouse Web that must reside on the same machine as your Web server. This
is so that the Web server can run this CGI program and pass it the user's
browser request. The PHCGI then takes that request and sends it to a
PowerHouse Web Dispatcher, which then figures out where the request can be
processed. Once an appropriate instance of the PowerHouse Web Server has
processed the request, and formatted the results as an HTML page, the
resulting HTML page is returned to the PHCGI process which, in turn, returns
the HTML page to the site's Web server -- which sends it back to the
original user's browser.

Since Linux is proving to be a very popular platform for Web servers, we
have decided to make just the PowerHouse CGI component available for Linux
at this time. We will consider also making the PowerHouse Web Dispatcher
available for Linux with the next full release of PowerHouse Web -- although
this is not a certainty and will likely be affected by the initial reactions
we receive to the availability of the PowerHouse CGI for Linux.

Please also note that due to their reliance on data access and networking
middleware (shared with the Cognos BI products) which is not currently
available on Linux, there are currently no plans to release either
PowerHouse 4GL or the PowerHouse Web Server component for Linux.

You will still need to build and run your PowerHouse Web applications on one
of our fully-supported PowerHouse Web platforms - MPE/iX, OpenVMS, HP-UX,
AIX, Tru64 UNIX, Solaris or Windows NT/2000 - but using the PowerHouse CGI
for Linux you will be able to run your Web server (e.g. Apache) on an
Intel-based Linux server, and successfully use that to communicate with your
back-end PowerHouse Web application server running on another platform.

The PowerHouse CGI for Linux is built and tested using the Red Hat 6.2
distribution of Linux. We have not tested it on any other distribution of
Linux, and currently have no plans to do so. You are quite welcome to try
running PowerHouse CGI for Linux on other distributions yourself, but our
usual proviso applies -- that we can only consider an issue to be a product
defect if it can be reproduced in the Cognos-supported environment, which in
this case is Red Hat 6.2.

The PowerHouse CGI for Linux will only run on Intel-based (or compatible)
servers, not under Linux running on PowerPC, UltraSPARC, Alpha, S/390, etc.

PowerHouse CGI for Linux is available free of charge to PowerHouse Web
customers, regardless of the platform on which you are currently running
PowerHouse Web. Please contact your local account manager for details.

Best regards,
Conrad
