Re: Question about the registry constantly check the provider.

[Alan Vinh]

Remember that it's not if the computer is ON, but if the application server that is servicing the end-points is up and running/serving. Just monitoring if the computer is on network and replying to the SNMP ping is not enough. You are looking at sending requests to a web server, so your application server that is running those web services must be running and on line. This means that you would have to communicate with those end-points to see if they are active, most web services will not support a "pinging" service due to bandwidth and computing resources just to say "yes, I'm still here". Alan Duan, Nick wrote: Alan is right. UDDI registry is not designed to monitor service availability. Some commercial products such as AmberPoint provide service monitoring functions as part of the SOA runtime governance solution. But such products are usually difficult to use and configure. If you just want to check if your computer is on or not, it's better to use SNMP-based monitoring tools (e.g. HP openview, but I am sure there are open-source tools as well). They are designed to monitor the availability of your network and hardware systems.

My guess is that the registry is NOT responsible for checking if the "end points" are active. It would be up to your application to check their end-points (i.e. the services) to see if they are active - i.e. after your application has obtained the service's end-point, your application would have to monitor that end-point to see if it is active, however this could per perceived as spamming by the server and it not good practice to keep pinging them "just to check". You application should handle the situation of when the end-point is down, i.e. what is the backup plan, etc. These end-points are web servers and there could be many of them in the registry so you shouldn't expect the registry to do maintenance check on its registered services.

I install the jUDDI and MySQL. and i had two computers that registered services in the registry. i'm try to figure out to ask the registry to constantly check see if the computers are available to provide the service(which mean see if the computer is on or not) i'm thinking using ping, but i don't know where to start it. does anyone know where and how to configure the database and registry? or which file i have to make change?
