I have finished the migration process of an Informix 4gl application to Genero BDL. When I use the httpdispatcher -f <file name> dispatcher the application runs well on a web page, but when I try to use the fastcgidispatcher -s -f <same_file_name_as_before> I get an empty web page with an error telling that the page cannot be loaded (no message from the fastcgidispatcher).

Can anybody tell me how to debug this issue.

Hi Hamza,

This sounds like a configuration issue. Did you check the Apache error / access logs ? Is there any particular message ?
For such issues, the best is to contact your support center with information like GAS version used,  GAS configuration file (as.xcf, wrapper.fcgi) , GAS and Apache logs.

Best regards,

Hamza,

Since you are running fastcgidispatch in standalone mode, let me assume you are using Apache 2.4 and you are looking at:
https://4js.com/online_documentation/fjs-gas-manual-html/?path=fjs-gas-manual#c_gas_config_mod_proxy_fcgi.html

Using the default conventions/names:

Make sure ps -aef | grep fastcgi shows you dispatcher running
http://host/gas/demos.html return the genero demo static html page ?

If not, your problem is indeed with Apache/fcgi or genero app server wrapper setup. You need to take a look at httpd.conf, apache error logs + wrapper.fcgi (as Guney suggested)
One common problem I have seen with this setup is permission on fcgi plugin

Thanks Laurent and Guney,
Right now i am able to start Apache 2.4.9 with mod_proxy_fcgi loaded.
When I run fastcgidispatcher manually in stand alone mode, the application starts. Apache is not starting fastcgi automatically, and I need to run Apache web sever and fastcgidispatcher as well.

Hamza,

With mod_proxy_fcgi, fastcgidispatch needs to be started manually and you need to create a cron/inittab program to restart it if it fails as Apache doesn't do it using this config

Look at point #3. Also, FYI, with Apache 2.4, mod_proxy_fcgi is required and I believe only Genero 2.50 is officially supported for this setup.
