when your app runs, does it register and then exit or does it stay running? do
you have the watchPID functionality switched on?
Is the app registering with an SA or with a DA directly?
Are the SA and the DA using the same scope? Are they just using DEFAULT?
cheers

I guess my question should be if SA received DAAdvert message, is there a way
to register a callback function to the DAAdvert event so that SA can know the
DA is there and register the service to it?
The way as you described "It is the responsibility of the SA to find DA's and
keep registering with them" - is it also done by the slpd "automatically"?
We have a test as following:
1) an application calls OpenSLP SLPReg when it started, the application is
a service agent points to a static DA IP address
2) run slptool findsrvs service:TESTAPP, it shows the application
registered with the URL
3) shut done the DA
4) restart the DA
5) run slptool findsrvs service:TESTAPP again, no service found
Based on the test case, "It is the responsibility of the SA to find DA's and
keep registering with them", which the application needs to know the DA is up
again and re-register it again. And it is not handled by slpd automatically. Is
this the correct?

Ren

The library and slpd service handle all of that for you. There is no need to
subscribe directly.

Thank you so much Nick for your answers, very helpful!
Is there a API to let SA to listen to the DAAdvert message? I guess SA must
already do it now in OpenSLP, but I can't find a API to subscribe the DAAdvert
message.

It is the responsibility of the SA to find DA's and keep registering with them.
The registrations have an explicit timeout, and if the SA doesn't re-register,
the DA assumes they are gone. For more information of this general sort, RFC
2608 can give a lot of useful information. http://www.ietf.org/rfc/rfc2608.txt
Of course we'd be happy to answer any subsequent questions.

If we have two DAs with the same scope deployed, does the SA registration will
populated to both DAs?
If a DA restarted, does SA need to re-register the service to it? Or it will be
populated automatically with the information from other DA?
