[ic] Interchange Installation steps

[Chetan]

Here is the exact point where I'm stuck
---------------------------------------------------------------
[root@html /root]# su interch
bash$ /usr/lib/interchange/bin/interchange -r
The Interchange server was not running
(//usr/lib/interchange/etc/interchange.pid).
Low traffic settings.
Calling UI....
...UI is loaded....
Interchange V4.6.5
Configuring catalog construct...Using default DBM database.
done.
bash$   
--------------------------------------------------------------

now when I load the page from browser it presents a welcome screen and
gives me a link to enter as customer. The link to enter as customer
doesn't work. It seems that the interchange process is not running.

------------------------------------------
bash$ /etc/rc.d/init.d/interchange status
interchange is stopped
bash$                    
------------------------------------------
