Can my Web browser applications be used with System i multi-tier web server configurations?

Yes, but there are some additional configuration things you need to consider. 

The browser version of the Visual LANSA Framework generates pages at runtime that are included in the LANSA for the Web page via Server Side Includes (SSI).

In a multi tier environment the web server and the application server are on different machines. (This is sometimes called a Model B implementation.)

Hence there is a requirement for the application server (where the include page is generated) to be able to have access to the web servers IFS system.

There is an IBM supplied file server called 'QFileSvr.400'.  Creating a directory in there using the host name of another machine in the network gives you access to the other machine's IFS.

Conditions:

  • The System i machines must be in the same network.
  • The user profile and password used by the LWEB job must exist in the web server machine.
  • The host directory created under QFileSvr.400 is NOT persistent across IPLs. It must be recreated after each IPL.
  • A firewall between machines might require extra configuration steps.

    • Command to execute:

          MKDIR DIR('/QFileSvr.400/<target System i host name>')
