[omniORB] TRANSIENT or COMM_FAILURE

[Serguei Kolos]

I have noticed recently that under different conditions omniORB4 throws 
different
exceptions in case when remote server is not running.

Case 1:  my client connects to the server, invokes a method on it and then
             waits for a time sufficient for the server to close it's 
connection as idle.
             If I then kill the server and tell to the client to invoke 
a remote method again,
             it will get TRANSIENT exception.
Case 2: my client connects to the server, invokes a method on it and 
then I kill
             the server and tell to the client to invoke a remote method 
again.
             In this case it will get COMM_FAILURE exception.

I have raised the issue about these exceptions in the comp.object.corba 
newsgroup.
Here are my questions the answers of Michi Henning. Do you agree with 
his opinion?
Cheers,
Sergei

A:
TRANSIENT. It means "nobody home".

A:
You mean they throw COMM_FAILURE? In that case, the ORB isn't
compliant.
