Hi,<br>
<br>
I've a similar problem as reported in this newsgroup a couple of weeks
ago (multiple-profile IORs) but this is related to omniORB 4.0.5. The
client tries to establish a connection to a server via a corbaloc
reference. Since the server host provides two multiple ethernet
interfaces both of them are listed in the corbaloc reference as follows:<br>
<br>
<a class="moz-txt-link-abbreviated" href="mailto:corbaloc:iiop:1.2@192.168.207.11:5555,iiop:1.2@192.168.208.11:5555/EventService">corbaloc:iiop:1.2@192.168.207.11:5555,iiop:1.2@192.168.208.11:5555/EventService</a><br>
<br>
Tests have shown that the guaranteed fault-tolerance behaviour works as
expected when the first interface is not available (i.e. the client
tries to establish a connection to 192.168.207.11, gives up after same
time and establishes a connection via 192.168.208.11).<br>
<br>
However, the TCP timeout delay which forces the ORB to use the second
profile can run into tens of seconds. This contradicts our requirements
and I have to find a way to reduce this delay. I've tried out a client
call timeout (e.g. clientCallTimeOutPeriod=1000) and retry to establish
a connection within a loop. But unfortunetly, it doesn't work. The ORB
only retries to establish a connection via the first profile. <br>
<br>
Maybe I've missed something. But is there any way to cope with that on
ORB level (forcing a profile switch)? Or do I need to adjust the TCP
settings of our platform (which is Redhat Linux 7.2). Has anyone a
solution or any experiences that may be helpful? Any help is
appreciated.<br>
<br>
I've attached both traces below.<br>
