DragonFly Server Configuration

DragonFly parameters

The parameters are passed to DragonFly in a "PL/1" fashion. That is that they follow a slash in the PARM= statement. Information before the slash is used for DEBUG and for address space tuning. An example is.


Setting the Port

If no port is specified, DragonFly uses the default http port number which is 80. Specify the port number in the Parm variable.


Each developer should be assigned an exclusive PORT number to use.

Setting the Remote Shutdown Password.

Instructions on how to set the password are found in the JCL member PASSWORD. Each developer may have their own loadlib and shutdown password.

Setting the TRACE features

To allow you to see what exactly is being passed to TCPIP, you may use the TRACE keyword. All information coming into and out of the server will be recorded in the SYSPRINT DD. To debug CGI programs you may use the CGIDEBUG parameter to display the contents of the CGI transfer and return variables. Trace should only be used for Debug purposes as it is IO intensive. LOGIC traces are less intensive than standard traces since Socket data is not presented to sysprint.


Our technical support may ask that you turn trace on and send the trace log in if problem determination is necessary.

Refresh of VSAM buffers


This parameter can be used in cases where one web server is updating the pages of another and VSAM share options are not checking data integrity. A url not found condition will cause a buffer refresh of the HTML database. The server will then retry the url. - New with version 1.4
