Support Changes

Hello,

 

I would like to announce changes to the ob-users <at> orbacus.com email support list.  As of Friday September 14, 2007, ob-users <at> orbacus.com will be no longer be available.  In its place we recommend users direct their questions and answers to the OrbZone forums (http://www.orbzone.org/forums/).  The OrbZone forums are more inline with what users expect these days and it will continue to receive the same visibility of both the Orbacus engineers and the community at large.  Paid support customers can continue to use support <at> orbacus.com, and will experience no change. If you have any questions or concerns don’t hesitate to contact me.  I look forward to seeing you all on the forums.  Long live Orbacus!

Corba contra IBM Websphere

>

  Hello,

 

Since a longtime Icouldn't work with my corba application and now I have to try solve a quite new for mevery big question  and it is urgent.

 

We evaluate the Corba solution against the IBM Websphere solution.

Some of our customers say that the native Corba solution is old? What is exactly the meaning of native? is that because of the Notification servfice which uses a native API. Can you explain me that?

They also want to have a certificat hanshake beetween 2 Websphere Plattforms?

Does Secure Socket Layer with authentication of both clent and server ertc..provide the same security as the IBM solution.

Can you explain me what I have to do to read to learn to get the same of better solution using Corba

Can you give me indications where Corba is better? or where i can read papers concrerning that?

 

It is a big question but I hoffe you will can me help.

I hope i shall receive somes informations from you qickly

 

Thanks a lot for your support

 

Mit freundlichen Grüssen. Avec mes meilleures salutations

How to use UserException in DSI

Hello!
    I am developing a corba application with ORBacus v4.3. In the server 
side, I use DSI to process client request. 
    Now I want to return UserException when some error occurs in the server 
side, but it is possible that there is no exception in the idl files.
    I don't know to use UserException. Thank you for any suggestion!

Subject: Re: [OB-Users] LoadBalancing...again, and again

So, Nobody at IONA can answer this question ?

Is it possible to have the LoadBalancer un-registering a server from its list of balanced servers when this
one is failed ?
It was the behavior I expected from the loadbalancer.
Instead it continues to provide a ref to failed server to requesting clients. Strange...

Gerard

You need to use the administrative utility to remove the member from the list.   Chapter 14 of the Orbacus
Manual (available on www.orbacus.com) gives the usage.

I recommend that you also use the OrbZone forums for message postings (www.orbzone.org).  Ob-users is a
community-based message list and although the Orbacus support engineers often help out, their
availability is dictated by the support load of our high priority support channel.  By posting to OrbZone
you will also gain the visibility of a whole new community of CORBA engineers that may be able to assist you.
Cheers.

Coredump in ORB_init()

Hello!
    When I test my application, core dump occurs suddenly. My application 
uses OB-4.3.1 on Linux platform.
    Below is the printed message on the screeen when core dump happened:
    non-compliant application detected:
    object was deleted without an object reference count of zero assertion 
failed: ref_ == 0
    file /home/zdbao/include/OB/Basic.h, line 1290

    I ever tried to debug the core file, below is some infomation:
    (gdb)where
    #0 in __kernel_vsyscall()
    #1 in raise() from /lib/tls/libc.so.6
    #2 in abort from  /lib/tls/libc.so.6
    #3 in ~RefCount at Basic.h 1290
    #4 in ORBInstance() at ORBInstance.cpp:284
    #5 in ORB_impl() at ORB_impl.cpp:241
    #6 in OBCORBA::ORB_init() at ORB_init.cpp:1020
    #7 in CORBA::ORB_init() at ORB_init.cpp:1040
    ......

    From the core file, I still don't know the actual cause of core dump. 
    Thank you for any suggestion!

LoadBalancing

Hello,

Just a simple questions about LoadBalancing:

- in the lbadmin command, what's the meaning of repository-id and 
object-id ?
- In the case where every server in the balanced group are in the failed 
state, is there an exception returned to the client ?
- For a server which register itself to the balancer, is it 
automatically put in an OK state while it was considered in the failed 
state ?

Thanks for your answers,

Gerard
