Best Practices for Deploying TWiki Software on GlassFish Application Server Using LRW
This Sun BluePrints article describes best practices in deploying TWiki software on Sun's open source GlassFish application server. Utilizing the Java technology long-running Web process (LRWP) protocol and running on the Solaris Operating System (OS), the platform can run up to twice the speed of Apache HTTP Server software implementations running on the Solaris OS. The result is reduced system overhead and the ability to accommodate greater numbers of users.
questions.
What's basically the difference between if I use the opensource and oracle glassfish (the one that requires license for production use)? Is there an evaluation period for the latter? Pls advise (0 Replies)

Catalyst::Manual::Deployment::FastCGI - Deploying Catalyst with FastCGI
FastCGI Deployment
FastCGI is a high-performance extension to CGI. It is suitable for production environments, and is the standard method for deploying
Catalyst in shared hosting environments.
Pros
Speed
FastCGI performs equally as well as mod_perl. Don't let the 'CGI' fool you; your app runs as multiple persistent processes ready to
receive connections from the web server.
App Server
When using external FastCGI servers, your application runs as a standalone application server. It may be restarted independently from the
web server. This allows for a more robust environment and faster reload times when pushing new app changes. The frontend server can even
be configured to display a friendly "down for maintenance" page while the application is restarting.
Load-balancing
You can launch your application on multiple backend servers and allow the frontend web server to perform load-balancing among all of them.
And of course, if one goes down, your app continues to run.
Multiple versions of the same app
Each FastCGI application is a separate process, so you can run different versions of the same app on a single server.
Can run with threaded Apache
Since your app is not running inside of Apache, the faster mpm_worker module can be used without worrying about the thread safety of your
application.
Widely supported.
FastCGI is compatible with many server implementations, not just Apache.
Cons
You may have to disable mod_deflate. If you experience page hangs with mod_fastcgi then remove deflate.load and deflate.conf from
mods-enabled/
More complex environment
With FastCGI, there are more things to monitor and more processes running than when using mod_perl.
Standalone FastCGI Server
In server mode the application runs as a standalone server and accepts connections from a web server. The application can be on the same
machine as the web server, on a remote machine, or even on multiple remote machines. Advantages of this method include running the
Catalyst application as a different user than the web server, and the ability to set up a scalable server farm.
To start your application in server mode, install the FCGI::ProcManager module and then use the included fastcgi.pl script.
$ script/myapp_fastcgi.pl -l /tmp/myapp.socket -n 5
Command line options for fastcgi.pl include:
-d -daemon Daemonize the server.
-p -pidfile Write a pidfile with the pid of the process manager.
-l -listen Listen on a socket path, hostname:port, or :port.
-n -nproc The number of processes started to handle requests.
See below for the specific web server configurations for using the external server.
WEB SERVERS
Any web server which supports FastCGI should work with Catalyst. Configuration recipies for well-known web servers are linked below, and we
would welcome contributions from people deploying Catalyst on other web servers.
