NAME

interchange - an e-commerce and general HTTP database display system

SYNOPSIS

interchange [--options] [file]

VERSION

5.6.1

DESCRIPTION

Interchange is a database access and retrieval system focused on e-commerce. It allows customers to select items to buy from catalog pages. The program tracks user information in sessions and interacts with an HTTP server through sockets.

Interchange has many, many, functions and features; they are too numerous to describe in this venue. Complete information can be found at its web site:

                 http://www.icdevgroup.org/
 
 

Interchange requires Perl 5.8.0 or higher; more information on Perl can be seen at:

                 http://www.perl.com/
 
 

OPTIONS

Interchange uses the Getopt::Long module, and most options will be recognized if they uniquely identifiable. The canonical forms are:

-a, --add

Add a catalog to the system. Information taken from the input file (or standard input). Implies reconfig=catalog. Example:

   echo "Catalog simple /catalogs/simple /simple.cgi" | bin/interchange -a
 
 

The information is in the form of a standard Interchange catalog line, and must be in the single-line format.

--runjobs=catalog[=job]

Run a jobs group which is a series of files in a directory with the name corresponding to the "job". For instance, if you set up a directory called ``weekly'' in your pages directory for the catalog "foundation", you can run those files with:

         interchange --runjobs=foundation=weekly
 
 

Files ending in .html (or whatever HTMLsuffix is for that catalog) are skipped. It is not tree-recursive --- directories are ignored.

Results can be emailed to an address if you specify --email=address, and they will be put in the jobs log file.

Alternatively jobs can be specified with --jobgroup=jobname before the --runjobs option. In other words, this will work:

         interchange --jobgroup=weekly --runjobs=foundation
 
 

This will NOT work:

         interchange --runjobs=foundation --jobgroup=weekly
 
 

-d dir, --dir=dir

Directory for VendRoot. This is where the Interchange configuration file will be looked for (if not redefined with "-f"), and where the log file will go (if not redefined with the ErrorFile directive).

-e name, --exclude=name

Exclude catalog from this startup.

-email=address

Email address to email jobs results to.

-f file, --config=file

Configuration file to use (default is interchange.cfg in VendRoot).

-h, --help

Display help on command line options.

-i, --inetmode

Run with internet-domain socket only. Normally Interchange runs with both UNIX- and internet-domain sockets (except on Windows).

--jobgroup=job

Sets the job for --runjobs if that is not included in the --runjobs call. MUST precede the --runjobs entry on the command line.

         interchange --jobgroup=weekly --runjobs=foundation
 
 

See --runjobs for an explanation of what this does.

--kill [signal]

By default, kills the server ungracefully with signal KILL (9, usually). The optional signal will be sent instead if supplied.

-q, --quiet

Suppress informational messages on startup. Only errors are shown.

--reconfig=name

Cause only catalog "name" to re-read its configuration.

--remove=catalog

Remove a catalog from operation; any future requests will get a not-found message.

-r, --restart

Stop and restart the server. This may take a long time if many catalogs are in use, and will temporarily take the system offline. If you want to change a UserTag, use the --add option instead.

--serve

This is the default if no mode options (--reconfig, --kill, --restart, etc.) are supplied.

--stop

Stop server gracefully with a TERM signal.

-t, --test

Report problems with config files; causes a complete configuration of the Interchange server but no server start.

-u, --unix

Run with unix-domain socket only. Normally Interchange runs with both UNIX- and internet-domain sockets. This will not work on Windows.

-v, --version

Display program version.

--DEBUG=1

Set to true value to run foreground in debug mode. It is normal to receive warnings about various things if you run with perl -w.

Directive=value

Set a Interchange global directive upon start (or --restart). Example:

         interchange SocketPerms=0666
 
 

This will start the server and override the default of SocketPerms or the value set in interchange.cfg for this instance only. Any --restarts must re-specify the directive if it is still to have that value.

name:Directive=value

Set a Interchange directive for catalog "name" upon start (or --restart). Example:

         interchange simple:VendURL="http://localhost/cgi-bin/simple"
 
 

This will start the server and override the default of VendURL for the value set in catalog.cfg for this instance only. Any --restarts must re-specify the directive if it is still to have that value.

ACKNOWLEDGEMENTS

Original author of Vend, ancestor to Minivend and Interchange, was Andrew Wilcox <amw@wilcoxsolutions.com>. Interchange could never have come into being without him. Interchange was based on Vend 0.2, with portions from Vend 0.3; both were produced in 1995.
