Question about the registry constantly check the provider.
Does anyone know how to integrate the registry and make the registry constantly check see if the provider is on.
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?
Thank You For Your Time.

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.
