When I start the server I get an exception like :
bitronix.tm.Configuration
cannot get this JVM unique ID. Make sure it is configured and you only use ASCII characters. Will use IP address instead (unsafe for production usage!)
What is the reason for this kind of exception and how can I fix this, when loading my component to production instance?
This is part of Bitronix configuration, the "bitronix.tm.serverId" property in the bitronix-default-config.properties file. See the docs for more details here:

I am using Ignite.Net and I have a very simple use case, wherein I want to put something into the cache without any transaction using CacheAtomicityMode.ATOMIC, to achieve that I am trying to use putIfAbsentAsync(key,Value) method.
But having a look at the description of the method on
https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/IgniteCache.html#putIfAbsentAsync-K-V- page, I am a bit confused!
Being new to Ignite can you please help me understand this better?Below are my doubts.
Description of putIfAbsentAsync method in the above link states the below
"For CacheAtomicityMode.ATOMIC return value on primary node crash may be incorrect because of the automatic retries.It is recommended to disable retries with withNoRetries() and manually restore primary-backup consistency in case of update failure."
Can you please explain what are automatic retries ? How and when to use it ?
What are pros and cons of disabling retries with withNoRetries() ?
I am also using ReplaceAsync(), RemoveAsync() And PutIfAbsentAsync() with the same cache configuration. Will there be any impact on the functionally of these functions after disabling retries?
What are the possible scenarios where in primary node may crash?
In what scenarios will putIfAbsentAsync() return false?
In what scenarios will putIfAbsentAsync() throw an exception? And List of all possible exception ?
I know the above link states the list of exceptions
(TransactionTimeoutException,TransactionRollbackException,TransactionHeuristicException) But all three are related to Transactions ! I don't really understand why Transaction exception will be thrown in ATOMIC mode, as there aren't any transactions in ATOMIC mode ?
I tried another use case have just one server node and one client node. Server Node creates and stores the cache and client Node just puts or gets cache ,When I manual stopped the server node just before a client node was trying to put something in the cache I got SocketException i.e java.net.SocketException: Socket is closed Exception. If this is a valid use case it would be better if you list these exception on the page.
I don't understand this line "manually restore primary-backup consistency in case of update failure" can you please explain what is primary-backup consistency ? and how to manually restore it ?
withNoRetries() just disallows retries. If operation fails, you get exception promptly. This compared to default behavior where operation will be retried until it is possible.
See more about ATOMIC limitations and IEP-12 in the docs. Note that normally this is only possible when more than one node leaves cluster at once.
The following message can be found in the server log in the file system on the Domino server:

Is there any way to get more info about the error? If there is, how to get more details?
First, I would suggest that you install the LogReader from OpenNTF.org by Jakob Majkilde (http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&name=XPages%20Log%20File%20Reader). It will give you easy access to the various logfiles on the server. You may need to look at different log files for specific issues - sometimes they land in the not so obvious place ;-)
When you have installed the log reader then look at messages just after (or perhaps before) the message above. In many cases several exceptions will be thrown - and you should look for the ones that refer to your own code. Changes are that you have missed initialization of an object in your own code. If you code in Java then the logs will be even more helpful.
In addition you could (should) consider using some kind of logging mechanism in your own code to tell you how far in loading/processing a page you are before failing. You could use the XPages OpenLog Logger: http://www.openntf.org/main.nsf/project.xsp?r=project/XPages%20OpenLog%20Logger

I can access this API/WS through
http://localhost:8080/ode/processes/ProcessManagement?wsdl.
I would like to get the Process Info of a Process through this service and active it.
The serivce has the matching operations getProcessInfo and activate.
With listAllProcesses I get all Processes of a delpoyed package.
For getProcessInfo/activate I need the Process pid.
I get a <ns:pid>, using this gets me a load of Exceptions.
Using the name of the process and other stuff I receive earlier doesn't work either.
The pid is of type QName, perhaps thats the root of the problem.
However I don't now how to typecast here.
(Tried all with the eclipse Web Services Explorer and soapUI)
question: How does a proper request for both Operations look like?
When I try to consume the webservice with axi2 via eclipse, there is a undeclared variable local in the AnySimpleType class. I'm not keen on using the service this way.
But since I'm already writing a Client for the DeploymentService I thought about this approach.
question: How do I properly access the ProcessManagement?
EDIT: I have a simular problem with the DeploymentService and the undeploy Operation.
EDIT2: I figured the Problem with the DeploymentService undeploy out.
I had to get the Packagename as String. Then a made a javax.xml.namespace.QName out of it. Then I used the setPackageName of said undeploy operation.
Answer to question number 1:
soapUI with listAllProcesses returns
<ns:pid>{ode/bpel/unit-test}HelloWorld2-1</ns:pid>
getProcessInfo wants
<pmap:getProcessInfo>
<pid>?</pid>
</pmap:getProcessInfo>
Now I replaced <pid>?</pid> with
<pid xmlns:odetest="http://ode/bpel/unit-test">odetest:HelloWorld2-1</pid>
and it worked like a charm.
I remember that there was an issue with parameter ordering when using the Axis2 generated WSDL. Could you try if building a request against the original WSDL located at http://localhost:8080/ode/deployment/services/ProcessManagement works?
EDIT: Now that I got the question correctly, the problem is that ODE expects the QName to be serialized differently, i.e. in the XML way instead of the Java way. Thus, instead of <ns:pid>{ode/bpel/unit-test}HelloWorld2-1</ns:pid> the correct notation is <ns:pid xmlns:odetest="ode/bpel/unit-test">odetest:HelloWorld2-1</ns:pid>.
When ever I try to do soft ware updates through my Eclipse Galileo, I get the following error
Unable to connect to repository http://pydev.org/updates/content.xml
Connection timed out: connect
Please help!!
That's a redirect to: http://update-production-pydev.s3.amazonaws.com/pydev/updates (so, you can try that directly).
If it still fails, it means that amazon is having issues (which means you'll have to try later again).
Cheers,
Are you using (just) http://pydev.org/updates as the url? The "location" field should only have "http://pydev.org/updates", no content.xml. Seems to be working fine for me (with Helios).
Actually I checked what happens when you use "http://pydev.org/updates/content.xml", and it does seem to give the type of error you describe. (You would think it could give a slightly better error, but oh well.)
I am curious about the proper way to stop a user from activating my plugin if their system does not meet certain requirements. Doing the checks is easy and I don't need any help with that, I am more curious how to tell WordPress to exit and display an error message.
Currently I have tried both exit($error_message) and die($error_message) in the activation hook method. While my message is displayed and the plugin is not activated, a message saying Fatal Error is also displayed (see image below).
Does anyone know of a better way, that would display my message in a proper error box without displaying Fatal error, it just looks really bad for new users to see that.
Thanks for any help in advance.
This is a little undocumented, as you might have noticed. Instead of die(), do it like this:
$plugin = dirname(__FILE__) . '/functions.php';
deactivate_plugins($plugin);
wp_die('<p>The <strong>X</strong> plugin requires version WordPress 2.8 or greater.</p>','Plugin Activation Error',array('response'=>200,'back_link'=>TRUE));
The lines above wp_die() are to deactivate this plugin. Note that we use functions.php in this case because that's where I have my Plugin Name meta data comment declaration -- and if you use a different file, then change the code above. Note that the path is very specific for a match. So, if you want to see what your path would normally be, use print_r(get_option('active_plugins'));die(); to dump that out so that you know what path you need. Since I had a plugin_code.php where the rest of my plugin code was, and since it was in the same directory as functions.php, I merely had to do dirname(__FILE__) for the proper path.
Note that the end of the wp_die() statement is important because it provides a backlink and prevents an error 500 (which is the default Apache code for wp_die()).
It is only a idea though. Try checking the wordpress version and compare then use php to through custom exception/error. PHP 5.0 try catch can be a good way to do it. Here is some resources.

You can try the first link. It is pretty basic. Thanks! hope the information will be helpful.
