- Dear mod_perl gang,
-
-
- The following is somewhat late in the "success story" thread of a few months
- ago, but I think there might be some interest for the database crowd. Below
is
- a brief summary of a talk that I gave at a meeting in Philadelphia last
week.
- Sponsored by Molecular Designs Limited (MDL), the meeting was attended by
- several hundred representatives of industry and government, and was
concerned
- with the problems related to large molecular and reaction databases, and
their
- use in combinatorial chemistry, drug discovery, etc. (These are databases
- consisting of molecular structures and their models, and reactions. A
database
- user can pose an sql in the language of chemistry - molecular structures
- drawn with ISIS/Draw or ChemDraw - to find data that have substructure
- similarity, conformationally flexible similarity, reaction similarity,
- and much more. The structures, models, and reactions are displayed using
- MDL's chime plugin, itself based on RASMOL, which renders 'live' 3-D
drawings
- that can be rotated and displayed in a number of ways from within the web
page.)
-
-
-
*******************************************************************************
-
-
-
-
-
-
- Last November, Dr. Shattuck proposed that we build a reaction database of
- reaction mechanisms studied by Dr. Mundy and his colleagues, using MDL's
- reaction database software. Furthermore, it was his idea that we make
- this a web project open to all. Our first idea was to buy a license for
MDL's
- ChemScape server, which links NetScape Enterprise server to MDL's database
- library. Unfortunately, the upgrade from our current MDL license to include
- ChemScape server was too expensive, not to mention NetScape Enterprise
server.
-
-
- I started working on a web server based on Apache and mod_perl that would
act
- as a gateway to MDL's database software.
-
-
- Although MDL's database server protocol is not public, they do provide a
- command line interface called hostcli, which has most of the functionality
- of the proprietary server. The use of hostcli is restricted to one machine,
- but within that machine one may run any number of hostcli processes.
-
-
- ColbyChem, the project that I presented at the meeting, makes use of hostcli
- by opening it on a pseudoterminal for each database user. The novel aspect
- of ColbyChem is its use of the integrated Apache/perl server running in
- single user (-X) mode for each database user.
-
-
- Because perl is embedded in Apache, dynamic variables are retained between
- calls to the server children. Certain Apache packages use this to open a
- persistent database connection to industry standard databases such as
Oracle,
- but this is not an option with proprietary interfaces, such as MDL's.
-
-
- In order to adapt this to the idea of opening hostcli on a pty for each
user,
- I run a dedicated Apache/perl daemon for each user, in single-mode (-X), on
a
- separate port. That way, each Apache daemon caches the perl program and
- retains dynamic variables between calls. In essence, it becomes a new
- application, composed of Apache and perl, running under my program. The
- effect is similar to an X client. The browser is like the X server.
-
-
- Entrance to ColbyChem is through a dedicated login daemon running on port
9000.
- Upon receiving a valid login name, the daemon forks an Apache/perl daemon on
- a port specified in a password-like file, and transfers the browser to this
- new port. Authentication, which is very important here, is carried out
entirely
- on this new daemon. The user supplies a password. ColbyChem encrypts it
- and compares with the encrypted password assigned to the user. If
successful,
- ColbyChem forks and execs hostcli on the pty. It then records the IP number
- and sends back a cookie for secondary authentication upon browser reconnect.
- The cookie is different for each session, is not based only on an easily
guessed
- system parameters like time or checksums, and does not reveal, to within the
- limitations of crypt(), the original or encrypted password. My solution for
- the cookie is to take the password, which is secret, and permute it using
- rand() seeded by time. The permuted cleartext password is then encrypted and
- sent back as the cookie. Thus, even if one knew the permutation order and
- cookie, it would still be impossible to recover the original password.
-
-
- ColbyChem presents side-by-side frames. The left frame contains a query
- builder and controls for hit-list logic and display. The right frame
displays
- the data indented in the natural hierarchy of the database. Models,
structures,
- and reactions are displayed using MDL's chime plugin.
-
-
- Essentially, ColbyChem is nothing more than a graphical front-end for
hostcli,
- written in 1200 lines of perl. The heart of ColbyChem is two routines, each
- a page of code. The first routine, rd2perl, translates an export file from
- hostcli into a perl data structure that has the hierarchy of the original
- database, i.e. it imports the database into perl. The second routine
- recursively descends the branches of this structure until it reaches the
- tips, whereupon it prints out the data indented to reflect the database
- hierarchy.
-
-
- MDL has just delivered an Oracle interface to its molecular and reaction
- databases. This opens the possibility of using established packages for
- persistent database connnections that offer the flexibility of ChemScape
- server from within Apache/perl, without the novel hack of running dedicated
- daemons on separate ports for each user.

+ iAgora was started in mid-1998, as a community site for
+ internationally minded people. After investigating the major
+ existing web development systems, we chose to go with Linux, Apache
+ and mod_perl. Three years later, we're very happy with this choice.
+
+ At iAgora we are constantly adding features and sections to our
+ site, and refining the ones we have. For us it was very important
+ to have a flexible platform, that would give us complete freedom in
+ organizing our code, and customizing how the pages are generated.

- Hi,

-
- I saw that there were requests for success stories, so here is ours.
- We had to create 21 websites that basically had the same textual content
- (but different ads+clickthroughs, different designs, different acces rights,
- etc...), that needed to sometimes remain unseen and act as gateways to other
- sites, and sometimes show up, with changing content and links according to
- user rights. Also, it had to answer search engine bots with different
- content using yet another database of robot user agents, as well as (coupled
- with LWP stuff) try to relate automatic posting to search engine databases
- to bots that came visiting (I know this isn't really good, but then, food is
- sometimes more important, :-( ) and to optimise meta tags, resubmission,
- etc...
-
-
- It's all done in mod_perl, and in three days time it served a bit
- more than 4 million mod_perl hits, and submitted 180.000 forms to search
- engines. Everything's running on a 300mhz x86, with 128megs of ram. As a
- comparison, the early development tests were done using CGI on the same PC,
- and ASP on a more powerful one running IIS. We also tried using java
- servlets but the results were so desperate that I will not mention them here
- in respect for those people that use them. Given the time it took either for
- the CGI to be finished, or for the ASP to connect to it's SQL Server 6.5 to
- yield the right results or send the right page, we had been planning to buy
- 5 other PCs to get the job done with those solutions. Our benchmarks run
- with about 15.000 iterations of a series of calls to the servers that were
- under no other load show that ASP is hardly faster than CGI when database
- access is used (and then you have to take into account the fact that the ASP
- PC was fairly stronger, (I don't remember the CPU but it had 512megs of
- ram), but that mod_perl induces a performance increase of around 1100% !!!
- Also, it seems to be using less ressources (though I haven't tested that

-
-
- http://openscape.org now contains the new site that I've been writing
- over the last 2 weeks.
-
-
- The site is generated 100% dynamically by my module Obelisk.pm. Apache
- 1.2.6 and mod_perl 1.10 are used, and the module is inserted to run on
- <Location />. MySQL and DBD::MySQL provide the back end object store.
-
-
- I keep all text, news items, and the like in the SQL database. at
- request time, the module takes the following steps.
-
-
- $method = $r->method;
- $loc = $r->uri;
-
-
- $loc is then parsed out. Depending on the "page" requested the module
- generates a page based on several SQL calls, and prints the result
- back out. I pass args on to the subrequests this way too, such as
- http://openscape.org/rnews/12 will read news item 12. It's all
- handled in the URL parsing. For the forms handling when you post a
- news item, I use CGI_Lite to grab things off POST. (If $method is
- POST), since Apache:: cant grab POST by default. I plan to implement
- my own POST handler, I just havent gotten around to it.
-
-
- You can post comments on news items, and those will be generated
- dynamically too. (a-la slashdot.org if you're familiar).
-
-
- The amazing part of all this is twofold. First, it's all done in 427
- lines of perl and 6 SQL tables. Slashdot is 2500 lines of code.
- Second, while I dont have any definitive numbers, this looks like it's
- going to scale very large. I've thrown a few large parallel requests
- at it (just simple LWP gets, in many parallel processes) and it doesnt
- seem to slow down. This box is just a P5/166 with 64megs RAM and Linux
- 2.0.31.
-
-
- This all occurs with no CGI.pm, no Apache::Registry, no on disk
- content but the Obelisk.pm. I am so spoiled by this method that I dont
- think I can go back. I'm writing a Doc on the process and I'll have it
- up soon. I know I'm not the first person to do this, but the process
- doesnt seem to be exceedingly documented. Oh, and Obelisk will be
- GPL'ed as soon as I gather it into a form that's fit for human
- consumption.

- Preface
-
-
- This is a story about how about I've used a combination of perl,
- Apache and mod_perl to create a component-based service architecture
- that implements a platform for building SMS applications. By reusing
- capabilities offered by Apache/mod_perl I saved a lot of time
- developing the system. The strong OO features of perl that I used
- enabled me to build a very flexible system as well to cope with future
- requirements. We had the platform in place in about 6 weeks, starting
- with absolutely nothing: no hardware, no development environment, no
- technology choices made beforehand.
-
-
- Introduction
-
-
- The purpose of the system to be developed was to provide a server
- platform on top of which arbitrary SMS (Short Message Service)
- applications can be developed quickly. It should be built using a
- stable and scalable architecture with room for future enhancements
- such as integrated billing and reporting options.
-
-
- An SMS application can be characterized by subscribers sending
- text-based commands to the platform and have the platform dispatch to
- the right application instance. The application instance handles the
- command, executing whatever application-logic defined by that
- particular application, and usually generate one or more responses. It
- should also be possible that the platform initiates messages to
- subscribers as a result of a request sent by another subscriber as
- well as be able to generate messages based on timers
-
-
- There also was a requirement to have the framework publish
- application-specific data in XML to allow customers to display this
- data on other media channels such as a website.
-
-
- Connecting the platform to external entities for the transmission and
- reception of SMS messages such as SMSC's (SMS Centers distribute SMS
- messages to and from mobile subscribers) and SMS Gateways (smart
- front-end to one or more SMSC's unifying the method to reach
- subscribers from multiple telecom operators) should be flexible enough
- to be able to "plug-in" different protocols such as
- HTTP/SMTP/CIMD/SMPP as needed.
-
-
- Component architecture
-
-
- Early on in the project I decided to go for a distributed component
- architecture. Individual components should be deployable on multiple
- physical machines. This offers the required scalability and the
- ability to define a convenient security scheme by running components
- on segments of a network with differing outside visibility
- requirements.
-
-
- As I started modelling this "world", I ended up with the following
- components:
-
-
- 1. Application server
-
-
- Within this application server, multiple instances of multiple SMS
- application instances should be running. The actual application-logic
- is running within this component. This component provides two external
- services:
-
-
- - handleMessage(CommandRequest)
-
-
- This service takes an instance of a CommandRequest object and runs the
- command in the appropriate application instance.
-
-
- - handleTimer(Timer)
-
-
- This services handles expiry of a timer set by the application-logic
- of an SMS application.
-
-
- - getView
-
-
- This service allows a client to retrieve application-defined views in
- XML.
-
-
-
-
- 2. Timer service
-
-
- A persistent service that maintains timers set by application
- instances within the game application server and invokes the
- handleTimer service of the game application services upon expiry of a
- timer.
-
-
- External service offered:
-
-
- - setTimer(Timer)
-
-
-
-
- 3. Virtual SMS gateway (VSMSC)
-
-
- This component handles communication with the outside world (the
- external entities such as SMSC's and SMS gateways). This component is
- split up in 2 subcomponents, one that handles input from mobile
- subscribers and one that handles output to mobile subscribers. Each
- subcomponent provides one service:
-
-
- - handleMessage(Message)
-
-
- The input component receives requests from the outside world using
- pluggable subcomponents that handle protocol details, the output
- component transmits requests to the outside world using pluggable
- subcomponents that handle protocol details.
-
-
-
-
- 4. XML Views service
-
-
- This component offers an HTTP interface to retrieve
- application-specific views in XML. It uses customer-specific XSLT
- stylesheets to transform the XML data. This component is largely based
- on Matt Sergeant's AxKit. AxKit allow the source of your "document" to
- be delivered by your own provider class by subclassing off of
- AxKit::Provider. My provider class talks to the application server's
- getView service while AxKit performs its miracles with all kinds of
- transformation options.
-

-
-
-
-
- Apache/mod_perl as a component container
-
-
- When thinking about how to implement all this I was tempted to look
- into doing it with some J2EE-thingy. However, there was this
- time-constraint as well as a constraint on available programmer-hands:
- I had one freelance programmer for 20 days and I had to arrange the
- whole physical part (get the hardware, a co-location site etc.). Then
- it struck me that this application server really looked like a vanilla
- regular mod_perl web application: receive request from user, process,
- send back reply. No html though, but Message objects that could be
- serialized/deserialized from text strings. There were of course some
- differences: the reply is not sent back inline (i.e. upon reception of
- a request via SMS, you can't "reply"; you have to create a new message
- and send that to the originator of the request) and there also was the
- timer service: I can't make Apache/mod_perl do work without having it
- received a user-initiated request.
-
-
- The good thing was I've been doing Apache/mod_perl for some years now
- so I knew beforehand I could create a schedule acceptable from the
- business point of view that was also feasible based on experience with
- the technology.
-
-
- So, for each component except the timer service, I defined separate
- Apache/mod_perl instances, one for the application server, one for the
- SMS output component, one for the SMS input component and one for the
- XML Views component.
-
-
- Each instance defines a URL for each service that the component
- running in the instance provides.
-
-
- Component communication
-
-
- I took a shortcut here. I wanted to go for SOAP here as it seems a
- natural fit. It will allow me to move components to other languages
- (management and marketing still seems hung up on java) fairly easy. My
- personal experiences with SOAP on earlier projects weren't too good
- and I just couldn't fit playing with SOAP into my schedule. So I took
- my old friends LWP::UserAgent, HTTP::Request and Storable to handle
- this part (perl object instance -> Storable freeze -> HTTP post ->
- Storable thaw -> perl object instance).
-
-
- The good thing is that this actually is a minor part of the whole
- system and I know I can put SOAP in easily when the need arises.
-
-
- "Breaking the chain"
-
-
- I did make one mistake in the beginning: all service calls were
- synchronous. The initial HTTP request would not return until after the
- whole chain of execution was done. With possibly long running actions
- in the server component, this was not good. I had to find a way to
- execute the actual code *after* closing the connection to the
- client. Luckily, Apache/mod_perl came to the rescue. It allows you to
- set a callback that executes after the HTTP responses are sent back to
- the client and after it closes the TCP/IP connection.
-
-
- Result
-
-
- We had the platform in place in about 6 weeks, starting with
- absolutely nothing: no hardware, no development environment, no
- technology choices made beforehand. Based on former experience, the
- decision to go with a LAMP architecture (Linux, Apache, MySQL, Perl)
- running on fairly cheap intel boxen was made quickly. MySQL was, and
- is, not on my wishlist, but the whole battle of moving Oracle in would
- have been both a time as well as a money killer, either of which we
- didn't have a lot of at the time.
-
-
- Aside from having one production SMS application (a mobile SMS game),
- I've done a prototype SMS application on this platform to check if it
- really is easy to create new apps. It took me about 4 hours to
- implement a "SMS unix commandline" application: I can login to the
- application server using SMS, send Unix commands with my mobile phone
- and receive their output (make sure your command doesn't generate more
- than 160 characters though). The application also maintains state such
- as the working directory I'm in at any given time.
-
-
- Performance is 'good enough' with the platform running on 2 fairly
- cheap Intel boxen, it handles 40 to 60 incoming request per second. As
- I haven't spent one second on optimization yet (anyone know the
- command to create an index in MySQL?), that number is fine for me. I
- did put 1 gigabyte in each machine though as the Apache child
- processes eat up quite some memory.
-
-
-
-
- Future enhancements and considerations
- SOAP
-
-
- I really want SOAP. It just seems to make sense to do so: it was
- invented for doing stuff like this and I like the concept of WSDL. It
- allows you to define the interface in an XML file so clients "know"
- what type of parameters the service needs as well as the return
- parameter types.
-
-
- SOAP will also allow new components that are not perl. SOAP is
- available in a lot of languages and integration of the various SOAP
- implementations is getting better every day (see here ).
-
-
-
-
- Framework for service-based architecture
-
-
- I'd like to extract the code that handles the communication between
- the components in the current system and create a generic framework
- that allows one to easily create an Apache/mod_perl-based components
- container. The available services would be registered in httpd.conf
- and there shoud be a service-discovery mechanism. On the client side,
- I'm thinking about something that makes it easy to create client-side
- stubs. Stay tuned...
-
-
-
-
- Apache/mod_perl 2.0
-
-
- This looks very promising to create generic components containers. It
- is very easy to create non-HTTP based services with Apache 2.0 with
- mod_perl's 2.0 support for writing protocol modules in perl. Also, the
- various multi-process models (most notably threading) available in
- Apache 2.0 should result in better performance or at least more
- choices as far as the process model is concerned.
-
-
-
-
- Lamp
-
-
- I'm still a little unsure about LAMP. Can we move to relatively cheap
- hardware and a free OS when we were used to (very) expensive HP, Sun
- or IBM hardware and get away with it? Personal experience and what
- I've read from others seems to indicate we can. Experience will tell,
- and if it breaks, moving the platform to either of the above three
- should be a no-brainer. We live in interesting times.

- Hello,
-
-
- another mod_perl success story:
-
-
- Have a look at www.wmboerse.de - it's a german real-time
- stock exchange simulation game for the soccer world championship.
- Participation is free and there are some nice prices to be won.
-
-
- The technology used is Apache, mod_perl, DBI and DB::Adabas. The
- project is sponsored by Sun Microsystems (they are supplying
- a Sun Ultra Enterprise 450 with 3 CPUs @ 300Mhz and 1GByte RAM at
- the moment), UUNET Germany (bandwidth) and Software AG
- (Adabas-D database).
-
-
- The server is a real beast. It's amazingly fast. The game is running
- since Sunday. At the moment, there are 2344 players, 183 of them
- have been active in the last 10 minutes. We are expecting a large
- increase in players as soon as national television reports about
- the game.
-
-
- The load is at 0.80, there are 123 processes, still 400MB RAM free
- (we plugged in 512 MB today, previously the box had 512MB).
- We will increase the maximum number of child processes if we get
- close to the current limit (100).
-
-
- Here's some data from the Apache status page:
- Server uptime: 4 hours 10 minutes 58 seconds
- Total accesses: 254671 - Total Traffic: 902.9 MB (!)
- CPU Usage: u27.68 s10.98 cu2.03 cs.63 - .274% CPU load
- 16.9 requests/sec - 61.4 kB/second - 3717 B/request
- 18 requests currently being processed, 14 idle servers
-
-
- Anyway, grab a browser and have a look. The project is a great success
- so far, and it couldn't have been done this easily and quickly without
- mod_perl and the other great free software out there.
-
-
- Thanks and enjoy!
