  Re: [tao-users] Problem with Fault Tolerance

Hi Charles,

Thanks for using the PRF.
Your analysis is making perfect sense. It is exactly the problem. However,
we need more work to construct a solution.

I had tried to debug this problem almost a year ago.
I actually also created a bugzilla entry for this. See.
http://deuce.doc.wustl.edu/bugzilla/show_bug.cgi?id=2414

I committed a fix, however, then reverted it because it broke other tests.

* orbsvcs/orbsvcs/FaultTolerance/FT_IOGR_Property.h:
* orbsvcs/orbsvcs/FaultTolerance/FT_IOGR_Property.cpp:

Reverted my change on
Thu Feb 23 15:10:18 UTC 2006 Wallace Zhang ociweb.com>
Because it made the two tests IOGRManipulation and 2247 failed.
I will supply a better fix with more thorough testing in x.5.1.

Unfortunately, I didn't have any time since then to finish up a sound fix
for this problem...

Thanks,

  [ace-users] ????         


Author: Ryan Cushnahan
Date: Jan 18, 2007 09:28

Hi I am trying to view all the posts which have already been posted to this newsgroup. I have tried adding the comp.soft-sys.ace newsgroup using Outlook but it keeps saying 'Server not found'. I wish to post a question but I'm sure it has been posted before but I can't view all the postings at the moment.
I have 2 questions:

1. How can I view all the 'previous' postings on the newsgroup?
and
the question I want answered is:
2. In the book 'C++ Network Programming Volume 1 - 2001 by D. Schmidt & S. Huston - Addison Wesley' In Part 1 chapter 3.7 the following code is given in the example:
auto_ptr pathname = get_url_pathname (peer);
which does not compile. However I found on the web a correction which says it should be:
ACE_Auto_Array_Ptr pathname (get_url_pathname (&peer))and this also does not compile.

Does anyone know the 'correct' way this should be?

Thanks

Ryan

  TAO: mobile CORBA and GIOP Tunneling Protocol         


Author: Daniel Lang
Date: Jan 18, 2007 08:05

Hello all,

we want to use TAO in combination with a bluetooth connection. OMG have
specified Mobile-CORBA in their document "Wireless Access and Terminal
Mobility in CORBA". In our case we only need the function "GIOP
Tunneling" especially "Bluetooth Tunneling".

Is there anybody who already uses TAO in combination with GIOP
Tunneling Protocol and Bluetooth? I can't find any code segments in
current TAO release concerning that?!

regards,
Daniel

  Re: Securing network connections with ACE_SSL_SOCK_*, how?         


Author: Amnon
Date: Jan 18, 2007 07:29

Hi Daniel,

Regarding your question, in an SSL Connection Establishment, just like
with TCP really, one side acts as the server (listening for
connections) and the other as the client (initiating the connection).
This is the difference between them and it is inherent in the protocol,
but it should not stop you from running a distributed network. You
simply need to decide which side will listen for the connection and
which will initiate it. Both the clients and the server may require a
certificate to initiate an SSL tunnel, it's all up to the flags you
pass the SSL Context/SSL object.

Hi,

Thanks for using the PRF.
> ACE VERSION: 5.5.3

You are using an old version of ACE, so I recommend you upgrade to
ACE+TAO+CIAO x.5.4 (i.e., ACE 5.5.4, TAO 1.5.4, and CIAO 0.5.4), which
you can download from

http://download.dre.vanderbilt.edu

under the heading: "Latest Beta Kit".

The DOC groups at Washington University, UC Irvine, and Vanderbilt
University only provide "best effort" support for non-sponsors for the
latest release, as described in

http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/docs/ACE-bug-process.html

Thus, if you need more "predictable" help for earlier versions of
ACE+TAO, I recommend that you check out

http://www.dre.vanderbilt.edu/support.html

for a list of companies that will provide you with ACE+TAO commercial
support.

Hi Keshava,

Thanks for using the PRF.

This version of TAO is old and many things have changed/improved.
Please upgrade to ACE+TAO+CIAO x.5.4 (i.e., ACE 5.5.4, TAO 1.5.4, and
CIAO 0.5.4), which you can download from
