Re: question object servers going down

[Michael Rumpf <michael rumpfonline de>]

Hi,

I just tested this with the "echo-server" and the "echo-client IOR_of_Server 10000" and took the server down while the client was running. The client just hangs without any error message.

Looking at the CORBA 2.3 spec (The Standard Exceptions are described in more detail here) there should be either an OBJECT_NOT_EXIST exception when the server was not available anymore before sending the request and a TRANSIENT exception if the server died after the request has beend sent.

I guess that in the latter case there must be some kind of timeout to detect this kind of problem.. ?

Am I right, and if yes, is this a known problem with ORBit 0.5.x ??
