You cannot run 2 web servers on the same machine without changing the configuration of one of them. By default all web servers Listen on TCP port 80 and thats the reason you are having problems.
Because the Oracle HTTP server powered by apache/1.3.22
is probably configured to start automatically it has already captured TCP Port 80 and therefore when you start WAMPServer it cannot get access to port 80, only one program can use a port at any one time.
You can change the port number that Apache listens on quite easily, as suggested by bob dylan.
Edit the httpd.conf file and change the config to tell Apache to listen on another port, so using the WAMPManager menus you would do this :-
left click wampmanager -> Apache -> httpd.conf
This will open the httpd.conf file in an editor, look for these lines
Listen 0.0.0.0:80
Listen [::0]:80
And change them to, for example
Listen 0.0.0.0:8080
Listen [::0]:8080
Save the file and then restart Apache
left click wampmanager -> Apache -> Service -> Restart Service
Now Apache will listen on port 8080 so the 2 Apache versions will not conflict with each other.
However this change means that you will have to put the port number on all your URL's like so
localhost:8080
localhost:8080/phpmyadmin
which can become a bit of a pain after a while.
A simpler solution would be to put WAMPServer on another machine and then there would be no conflict. Remember WAMPServer is configured to be a development web server and not a LIVE web server. It should run just fine on your own personal workstation/PC.
