Setting the Priority of a CGI Program

The priority of a CGI program can be set using the nice parameter of the send-cgi function. This is a UNIX-only parameter and accepts an increment that determines the CGI program’s priority relative to the priority of the server process. Typically, the server is run with a nice value of 0 and the nice increment can be between 0 and 19.

0

The CGI program runs at the same priority as server

19

The CGI program runs at a much lower priority than the server

As with all other CGI variables, the nice value can be configured per virtual server.

While it is possible to increase the priority of the CGI program above that of the server by specifying a nice increment of -1, Sun does not recommended you to do so.

For more information about send-cgi, see the Sun Java System Web Server 7.0 Update 1 Administrator’s Configuration File Reference.

To Configure CGI Properties for a Virtual Server

You can configure CGI variables for a virtual server either using the Admin Console or using the CLI. The following procedure describes the steps:

1. Configure CGI variables.

   • Using the Admin Console:

     1. Select Common Tasks tab > CGI Directories from the Virtual Server Tasks list.

        The CGI Settings window is displayed.

     2. Specify the nice value as desired.

     3. Click Save to apply your changes.

   • Using the set-cgi-prop command.

     Example:

     ./wadm set-cgi-prop --user=admin --password-file=admin.pwd --host=serverhost --port=8989 --config=config1 nice=5
