Just a quick addition to Ashish's instructions: for this demo the nodes
which will be the webservers need to be Linux, and the SF daemon needs to
run as the root user (in order to install Apache). The other nodes can be
anything.

[Ashish A. <aw...@in...>]

Hi Alan,

1) set up a few nodes running the latest daemon
2) edit the file .../dynamicwebserver/sf/nodes.sf to set some nodes with
specific roles
    - web servers
    - the load balancer
    - service managers
    - stress test host
Example:
stressTestHost "localhost"; // node where stress test service runs

serviceManagerHost "localhost";
balancerHost "node1";  // name of the host where balancer service runs

serverHost1 "node2"; // name of the host where web server will run
serverHost2 "node3"; // name of the host where web server will run
webPort 80;
serverHosts extends vector {
    -- ATTRIB serverHost1;
    -- ATTRIB serverHost2;
3) start up the example using .../sf/serviceTemplate.sf
    - which will bring up the manager on the node you are deploying on
    - the load balancer on the load balancer node
    - a single web server on one of the server nodes

4) start a load generator using .../sf/loadGeneratorTemplate.sf
    - this will start a slider component which you can use to vary the load

5) as you vary the load it may go above the top threshold, in which case a
new web server will be created on one of the nodes

Note that the first time a web server is deployed on a node, apache tar file
will be
downloaded from the web server [default is serrano.hpl.hp.com] this is
configured in ../sf/installApacheIfNeeded.sf and ../sf/webTemplate.sf

I believe you have connectivity to this host else-
You may have to configure ServerHost attribute in webTemplate.sf and
installApacheIfNeeded.sf and point to a web server which serves tar file for
apache installation.

Hope this helps.

Ashish

Hi guys...

I'm an engineer with HP doing an investigation into SmartFrog and am going
to do
a short presentation to my fellow team members.  I'd like to try and run
some of
the dynamicwebserver demos since this applies pretty well to our general
area of
expertise.  Can you give me some pointers on which *.sf file(s) to
edit/configure so that I can play around with this demo?  I've validated the
install by running the sfDaemon and the Printer/Generator demo.

Thanks for your help,

Alan

Hi guys...

I'm an engineer with HP doing an investigation into SmartFrog and am going to do 
a short presentation to my fellow team members.  I'd like to try and run some of 
the dynamicwebserver demos since this applies pretty well to our general area of 
expertise.  Can you give me some pointers on which *.sf file(s) to 
edit/configure so that I can play around with this demo?  I've validated the 
install by running the sfDaemon and the Printer/Generator demo.

Thanks for your help,

Alan
