[MOBY-dev] Dead services and how to figure them out

[Sebastien Carrere]

Bonjour ,


Thanks Andreas to restart the discussion about DeadServices and cleaning 
the registry.
I encounter the same problem in Remora.
The DeadServices list provided  is not exhaustive as you say.

I launch every night a cleaner which do this thing:
- get all services registered in Mobycentral
- try to execute them with the perl command: eval 
{$service_instance->execute(XMLinputlist =>[[]])};

Here is my list of Dead services (Ihave got also list for the 3 past 
days for testRegistry and Inab registry) :
http://lipm-bioinfo.toulouse.inra.fr/remora/sessions/blacklist.mobycentral

(Format is "service_name    auth_uri    registry_name    error_message")

Most of them are 404 or 500 errors.

If my test is correct, that means that around 10% of services are dead.
And here I cannot test if the returned message is well-formed (many 
changes happened since the birth of BioMOBY and maybe some services have 
not been updated), so it's at least 10%...

 From my point of view, this problem of dead/non-functionnal  services 
is really a critical one.
We develop tools based on web-services and we advice our users to use 
tools such as Taverna, Remora etc...
So if the basis (web-services) is not robust, we lost all our credibility.

We deploy here (Toulouse, France) procedures to test our services every 
night to ensure their availablity and stability.
I think it's time to currate the main registry.

What do you think about this ?

Sebastien
