[openorb-users] Location Forward problem

[Jacek C. <jc...@ag...>]

Hello all,

Is it possible to make a deep copy of an object reference in OpenORB? I 
have the following problem:

At a client side I have two corba references to the same remote object. 
When I invoke an operation on the object using one of these refs and get 
location forward exception, both references are updated. It means, the 
one I used to invoke operation as well as the other that I have not used 
  yet, both point to the new location.

This behaviour is in general reasonable but I need the unused reference 
to point to the previous location of the object. Is there any chance to 
do it avoiding reference conversion with object_to_string/string_to_object.

BTW I'm not sure if it is important but I set the property 
bindings.discard_old to true.

Set maxThreadPoolSize in the openorb configuration file. And make sure that
you are using an appropriate threading strategy in the ORB / POA
configuration, not "thread per client".

This is probably not a "Solaris only" problem. If you are having
difficulties getting a profiler to run (see below) you might be able to
reproduce this on Windows. If you can't do that, profiling tools typically
support remote profiling. Read your profilers documentation how to do that.

Have you tried to paste this error message into the google search box?
Whenever I run across some error message, this strategy works quite well for
me...

A profiler is a GUI driven program, just like your IDE, so it needs to open
a window on your desktop. X11 is the GUI environment of Unix Systems.
Dedicated unix servers often don't have a GUI running and allow interaction
only via the command shell.  The stack trace says that YourKit is trying to
open a window and it failed because X11 is not there or not configured
correctly. If X11 is running, ask your sysadmin for help. If X11 is not
running, use one of the options I described above.

[openorb-users] CPU Load Average Threshold Alarm due to corba

[<ras...@wi...>]

Hi

 

 

Scenario 1:

===========

 

Here the customer site was using the OpenORB-1.3.1 from past few years. Code was written for that. JDK was recently up versioned to JDK-1.5_014. Previously there was a COMM_FAILURE error. It was fixed by this new JDK version. Hence new JDK was applied. But Corba related code changes are not done. Also in jdk we increased the memory size from 8k.

 

After the application of this JDK version from application side every 3-4 days the GUI goes to hung state at this stage customer need to restart all the services. Once they restart, this error will disappear and the system comes to normal state. In the logs we see the below mentioned error messages.

 

Hence I was checking about the Root cause for this error.

 

Do we need to tune the java processes? Is this is Java process issue?

 

 

Scenario 2:

===========

  Here It was found the corba is using high CPU load average. We tested by launching GUI and sending the notifications.Some Java threads will be left in the run queue.

 

1.Will there be any memory leak in corba? If yes when it will occur? How can   we identify the corba memory leak and is there any solution to fix this.

2. The java threads which are created are left in the runnable or running queue. Hence the LWP's are keep on increasing. Is this is caused by the clients not handling the code properly and threads are not killed? How we can correct this. Is there any tool to identify corba memory lea.

    

Please help me with any pointers to above mentioned problems.

 

 

*      For Naming service, client(GUI) needs to ask ORB to get the server object reference and send request and get response, Server doesn't have knowledge about how ORB handle the details of communication, that is one of reasons why we use CORBA but not pure socket call.    Is this statement is correct?

  

*      For Notification service, is there any configuration inside ORB which can let us to set the number of max threads?  Is there Any Solution for this.

 

 

*      Is there any tool that can be used to identify the Corba threads and how it communicates on Solaris 9/10. how to check the name sevices and notification services are correct.

 

 

*      I tried to use your kit as per  suggestion but 

I am getting the error .

Rahsmi,

Client keeps a connection open but doesn't send any further requests. 
The server tries to read a few bytes, but because the client doesn't 
send anything, that read times out with an exception. This is perfectly 
normal, so it shouldn't be logged by the server. This has been fixed in 
OpenOrb 1.4.0.

Sure, you have multiple clients, right. They all time out at some point.

If the client ORB is robust, this is probably not the cause of your 
problems. If you have control over the clients, try to debug them or use 
a profiling tool like JProfiler or YourKit to detect deadlocks.

Like I said in my earlier email: I don't know your code and you seem to 
use SSL features of OpenORB I have never used personally, so I can't 
really help you. All I can say is that you really should upgrade to 
OpenOrb 1.4.0.

Lars

Yes. This is all very long time ago, but I remember that we had to 
change the code to support valuetypes in JDK 1.5. Not sure if there was 
anything else, please check the WHATSNEW files from later releases for 
every module you use. OpenOrb 1.3.1 was released more than a year before 
JDK 1.5, so that combination has definitely never been tested.

Note also that TONS of other issues were fixed between 1.3.1 and 1.4, so 
I think it might be more risky to stick with the old version than update 
to a newer one.

I have absolutely no idea. I no longer have the sources for OpenOrb 1.3 
locally, I don't have your sources, and I have never used CORBA over 
SSL. I'm afraid I can't help you that much :-(

Re: [openorb-users] Using OpenORB with NSIcom CrE-ME VM for PDA's

[Bryan W. <br...@ar...>]

NSIcom's JVM has been stripped down due to the memory size 
limitations of PDAs.

My guess is that OpenORB initialization requires the orb to connect 
to a socket or acquire some other such resource, and the underlying 
java library is missing. It could also be that the java library is 
included but WinME does not include a DLL that the java library 
depends upon.

Wish I could be more help - I tried to build a java app on a PDA 
using CrEme once and it was not great.

Good luck

Cheers!
Bryan

Re: [openorb-users] Using OpenORB with NSIcom CrE-ME VM for PDA's

[Wouter W. <wo...@xs...>]

There's no real possibility of debugging it on the creme JVM :(
And I know CrEme can find the openorb jar files, cause if I move them, I get 
a classdefnotfound error.

I e-mailed NSIcom about it as well,
this error leaves me kinda clueless.
If only I knew why it can't instantiate the ORB implementation.

Hmmm... I have no experience with mobile java so I can't really help, 
but if they are saying "notably swing is [now] supported" maybe testing 
CORBA is not on their priority list yet? Another possible pointer: Are 
you sure that your bootclasspath setup is equivalent to the windows one?

You should really try to debug this and find out where exactly the 
init_orb call fails.

[openorb-users] Using OpenORB with NSIcom CrE-ME VM for PDA's

[Wouter W. <wo...@xs...>]

Hello,

I'm trying to run an application using OpenORB on the CrE-ME virtual machine,
but unfortunately, I can't get it to work, and I don't know why.
I might be doing something wrong when using OpenORB, or there might be a problem with the VM.

I am using OpenORB 1.3.0.
I tested the application on windows, using JDK 1.3.1,
this works fine. The application is able to initialize the ORB and contact the naming service.

Some information about the CrE-ME VM, from the website ( http://www.nsicom.com/Default.aspx?tabid=138 )


J2ME-CDC implementation. Compliant with J2ME CDC 1.0 specification - based on JDK 1.3.1.
CrEme supports any Java package written entirely in Java, and supported by JDK 1.3.1 (or below). If the java package however relies on native methods, these native methods will have to be ported to the target platform.


Based on this information, I had good hope that it would work :)
but when I try to run the application on the CrEme VM, it outputs the following error:


org.omg.CORBA.INITIALIZE: can't instantiate ORB implementation org.openorb.CORBA.ORB  
org.omg.CORBA.ORBSingletonClass=org.openorb.CORBA.ORBSingleton
        at org.omg.CORBA.ORB.init_orb()
        at org.omg.CORBA.ORB.init()


So basically it fails when trying to initialize the ORB.
I assume the code to be correct, cause it works fine on jre 1.3.1.

So what could cause an error like this?
I made and placed the orb.properties file like instructed
When I don't use place the orb.properties file in the lib directory, the error is similar:

org.omg.CORBA.INITIALIZE: can't instantiate ORB implementation org.openorb.CORBA.ORB

[openorb-users] jdk-1.5.0_14 and openorb-1.4.0 compilation with -xlint

[<ras...@wi...>]

Hi all,

=20

I am compiling openorb-1.4.0 with jdk1.5.0_14  with -xlint option.  Also
I am compiling corba related *.java files with the same jdk.

I see warnings. Please help can I ignore these warnings? What about
serializable classes. I am using Transient naming service=20

And notification service of OpenORB. Is there any effect on this.Below
are the errors during compilation.

[openorb-users] org.omg.CORBA.COMM_FAILURE while compiling openorb with JDK-1.5.0_14

[Dahiya, K. (GE H. consultant) <Kir...@ge...>]

=20
Hi Rashmi,

One of the reasons of the occurance of this error could be that your
application is taking sun orb at one end inspite of taking open ORB.

In order to fix this thing add the following in your compilation path:

:. -Dorg.omg.CORBA.ORBClass=3Dorg.openorb.orb.core.ORB
-Dorg.omg.CORBA.ORBSingletonClass=3Dorg.openorb.CORBA.ORBSingleton
server.java=20


Hope this will help.

Thanks & Regards

Kiran

[openorb-users] Beginner's question on openorb.home

[jerome.jeanjean <jer...@la...>]

Hello everybody,

I've read the documentation about openorb.home.
As I understand this is set by default to resource:/org/openorb/. This way,=
 everytime there's a reference to it, it will look into the openorb jar to =
find what it needs.

My question is simple: how is that variable set to resource:/org/openorb/ b=
y default ?

I can't find it in any file.

Could anyone explain how this works for a beginner ?

Thanks.

Jerome.

Re: [openorb-users] how find cpu and memory usge for corba?

To get a rough picture you could use the standard unix commands like
top or vmstat.

If you neded to drill down more, you can profile cpu and memory usage
using standard profilers like yourkit, jprofiler, etc - I guess most
of them are supported on solaris as well.

If you need to dig really deep, you could use a Solaris tool called
DTrace, which was introduced in Solaris 10. This is a command line
tool that allows you to take probes on every level of the runing
software stack (java code, jvm and kernel activities). Unfortunately I
don't have access to a Solaris 10 machine, so I have never been able
to use dtrace myself, so for details please read the dtrace docs on
sun.com

Lars

Re: [openorb-users] error in event channnels

[<lak...@t-...>]

Rashmi,

I know that CORBA applications are not exactly easy to debug, but I 
can't help you much without knowing your code. Like I said in August:

    The NotFound exception is thrown when a lookup in the NamingService fails. This could be for a variety of reasons: Maybe you misspelt the name in your code? Maybe your server is not even registered in the NamingService when you access it from your client? Maybe your server and your client are talking to different NamingServers?
      

Regards,
Lars

[openorb-users] Extracting user defined Any types

[Henning R. <hr...@ne...>]

Hello all,

I'm trying to extract a user defined Any type. There are only two kind 
of types, NotUsed and StringInfo. The only type passed around is the 
StringInfo which is pushed by an omniORB eventservice.

If I just extract the StringInfo using StringInfoHelper, everything 
works fine.

If I try to extra the Any (containing a StringInfo type) into a NotUsed 
type then the program throws an exception I cannot catch apparantly, and 
the eventservice disconnects me.

If I try to determine the type of the Any using type() then equal() 
returns false for both types (even though I know the type is StringInfo).

Does anyone have a suggestion how to do this? The code for my push 
operation is listed below and is made after an example from the iona 
website.
Might this be because I'm trying to interact with omniEvents?

Any suggestions are much appreciated,

Regards
Henning


Source code:

IDL:

struct StringInfo {
   string who;
   string what;
   short id;
 };

 struct NotUsed {
   string s1;
   short s2;
   short s3;
   string s4;    };

Java:

  public void push(Any data) {
       StringInfo msg;
       NotUsed nu;

       try {
           if (data.type().equal(StringInfoHelper.type())) {
               msg = StringInfoHelper.extract(data);
               System.out.println("StringInfo");
           } else if (data.type().equal(NotUsedHelper.type())) {
               nu = NotUsedHelper.extract(data);
               System.out.println("NotUsed");
           } else {
               System.out.println("Unknown");
           }                              } catch (BAD_OPERATION e) {
           System.out.println("Bad op");
       } catch (Exception e) {
           System.out.println("Error");
       }        
}

Re: [openorb-users] any debugging tool to find out the corba errors.

[Mark J. <mar...@ti...>]

Hello Rashmi,

Generally speaking COMM_FAILURE exceptions stem from networking
problems. One tool you may wish to try would be ethereal
(http://www.ethereal.com/), it has protocol support for GIOP.

As far as trace or debug logging is concerned, there are examples of how
to configure that in
http://openorb.cvs.sourceforge.net/openorb/OpenORB/src/config/OpenORB.xml?revision=1.5&view=markup

Hope this helps you out.
