Hi,

I use omniORB::setClientCallTimeout( obj, timeout ); 
Before the narrow call and reset it after using
omniORB::setClientCallTimeout( obj, 0 ); 

Obj is a CORBA::Object_ptr (generally it comes from a resolve())

HIH

Fred

Thanks for the quick response.

I tried the following settings both in my omniORB.cfg file as well as
passing them as command line parameters when calling the ORB.init(), but
the timeouts do not seem to be taking effect.

My script lists all of the contexts/factories registered in the naming
service.   The script gets a list of IORs from the NameService then I
try to narrow those IORs to a CORBA.Object.   If the narrow fails, I
mark the factory as 'down' and a successful narrow will mark it as up.

The problem I'm having is with this narrow call.   Despite the timeouts
I've set in my omniORB.cfg, the narrow still takes much longer than the
sepecificed timeout when trying to narrow a factory that isn't 'on the
wire'.

Here's my omniORB.cfg:

InitRef=NameService=corbaname::NameServer:5000
scanGranularity = 5
clientCallTimeOutPeriod = 2000
serverCallTimeOutPeriod = 2000

What am I missing?

Yes, just put entries of clientCallTimeOutPeriod, etc. in omniORB.cfg.
Look at sample.cfg and section 8.3 of the omniORB
manual:

Pass them to ORB_init.

Cheers,

Duncan.
