Deactivating MDB using JMX

Hi All,
I have a requirement to deactivate a MDB from its own onMessage method , when it detects some error.
This is the piece of code I was using:
DeployerRuntimeMBean deployer = DeployerRuntime.getDeployerRuntime();
deployer.deactivate("MDBName", null, null);
I was able to pause the MDB by running the above code in our developer environment where there is only the admin server . When I tested this in our UAT environment I was getting a null pointer exception. In UAT environment we are having an admin server + a cluster . There is only a single managed server in the cluster and the MDB is targeted to the cluster.
Any clue why this error is happening.
TIA

If you need to access this from a managed server, you could use one of
the getDeployerRuntime methods that connects as a client to the admin
server:

How to read the messages in the JMS Queue using JMX

Hi,
          I want to read messages in the JMS queue using JMX. I was able to read using QueueBrowser but want to modify priority of the messages using JMX.
          I tried to use JMSDestinationRuntimeMBean but it does not allow us to read messages unless we pass the message Id. Is there any way that I can get all the messages in the queue.
          I am using Weblogic 8.1 SP4
          Can someone please help me in this regard.
          Thanks,
          Kiran.

Hi,
As far as i know, JMS Object Messages is not supported by XI JMS adapter.
you need to have the JMS provider to transform the message to bytes messages.

Using JMX to get status information about NetWeaver cluster

Hi everybody,
We are trying to use JMX to get some status information about NetWeaver cluster.
For example, using the MBean with the name u201Ccom.sap.default:name=EL1,j2eeType=SAP_J2EEClusteru201D we can obtain the list of all instances running in cluster. Here an instance is a u201CJava instanceu201D in the NetWeaver terminology.
The method u201CgetInstanceNodeIDsu201D provides us with a list of all nodes of an instance.
Concretely, calling this method for a cluster running on one machine with two java processes, we get the following list of node Ids: u201C0, 1476420, 1476450, 1476451u201D where the last two correspond to the two java processes.
What are the first two node Ids from the list?
How can the last two node Ids be identified as java processes?
How can we obtain status information about each java process (node id) ?
Thanks for all ideas,
Radu

As there seems to be a lot of interest in this subject, and since I found some form of solution, I thought I'd share it with you.
In the es-cli interface, there is a thing called browse mode. Activate it by typing browse after logging in.
Now you can easily browse your network and all of the managed objects. Use getattributes at the end of each branch to see the properties of objects. So far, I've indexed all of the kernel reader module, the health monitor module, the common config reader and the config reader for workgroup servers. If my employer allows, I will post results to http://tille.garrels.be/training/sunmc/ - check later this week.

Help needed in using JMX APIs

Hi
My requirement is to retrieve the JNDI Names of the JMSConnectionFactory and the JMSQueue using the Connection factory or Queue name. In short im trying out a feasibility of reading the JNDI values for queues from weblogic config.xml instead of reading them from a properties file.
I developed a sample code using JMX APIs that will fetch the JNDI names of all the JMS destinations available for a particluar JMSServer.
But is there any way to retrieve the JNDI names based on the queue names .. in general i will give queue name as input and i want the queue's JNDI name as output.
My sample code is :
import java.util.Iterator;
import java.util.Set;
import javax.management.ObjectName;
import javax.management.QueryExp;
import javax.management.Attribute;
import javax.naming.Context;
import weblogic.jndi.Environment;
import weblogic.management.MBeanHome;
import weblogic.management.RemoteMBeanServer;
import weblogic.management.WebLogicObjectName;
import weblogic.management.configuration.JMSQueueMBean;
import weblogic.management.configuration.JMSServerMBean;
import weblogic.management.configuration.JMSConnectionFactoryMBean;
import weblogic.management.configuration.JMSDestinationMBean;
import weblogic.management.runtime.JMSServerRuntimeMBean;
import weblogic.management.configuration.JMSDestinationMBean;
public class JMSAddQueue {// The name of the WebLogic domain, please change this to match the //// name of your installation specific domain name
private static String weblogicDomain = "conciergetestdomain";// The name of the WebLogic server, please change this to match the //// name of your installation specific server name
public static void main(String[] args) {
     try
          Environment env = new Environment();
          env.setProviderUrl("t3://localhost:7001");
          env.setSecurityPrincipal("system");
          env.setSecurityCredentials("weblogic");
          Context ctx = env.getInitialContext();
          MBeanHome home = (MBeanHome) ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
          ctx.close();
JMSServerMBean cf = (JMSServerMBean)home.findOrCreateAdminMBean("TESTSERVER","JMSServer", weblogicDomain);
JMSDestinationMBean[] jdb = cf.getDestinations();
System.out.println("** The JNDI name is : "+jdb[0].getJNDIName());
catch (Exception e) {
e.printStackTrace();
}Is there any way to retrieve the JNDI names using the queue names ?
Thanks

Best practice to monitor 10gR3 OSB performance using JMX API?

Hi guys,
I need some advice on the best practice to monitor 10gR3 OSB performance using JMX API.
Jus to show I have done my home work, I managed to get the JMX sample code from
http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/jmx_monitoring/example.html#wp1109828
working.
The following is the list of options I am think about:
* Set up: I have a cluster of one 1 admin server with 2 managed servers, which managed server runs an instance of OSB
* What I try to achieve:
- use JMX API to collect OSB stats data periodically as in sample code above then save data as a record to a
     database table
Options/ideas:
1. Simplest approach: Run the modified version of JMX sample on the Admin Server to save stats data to database
regularly. I can't see problems with this one ...
2. Use WLI to schedule the Task of collecting stats data regularly. May be overkill if option 1 above is good for production
3. Deploy a simple web app on Admin Server, say a simple servlet that displays a simple page to start/stop and configure
data collection interval for the timer
What approach would you experts recommend?
BTW, the caveats os using JMX in http://download.oracle.com/docs/cd/E13159_01/osb/docs10gr3/jmx_monitoring/concepts.html#wp1095673
says
     Oracle strongly discourages using this API in a concurrent manner with more than one thread or process. This is because a reset performed in
     one thread or process is not visible to another threads or processes. This caveat also applies to resets performed from the Monitoring Dashboard of
     the Oracle Service Bus Console, as such resets are not visible to this API.
Under what scenario would I be breaking this rule? I am a little worried about its statement
     discourages using this API in a concurrent manner with more than one thread or process
Thanks in advance,
Sam

Hi Manoj,
Thanks for getting back. I am afraid configuring aggregation interval from Dashboard doesn't solve problem as I need to collect stats data of endpoint URI or in hourly or daily basis, then output to CSV files so line graphs can be drawn for chosen applications.
Just for those who may be interested. It's not possible to use SQL to query database tables to extract OSB stats for a specified time period, say 9am - 5pm. I raised a support case already and the response I got back is 'No'.
That means using JMX API will be the way to go :)
Has anyone actually done this kind of OSB stats report and care to give some pointers?
I am thinking of using 7 or 1 days as the aggregation interval set in Dashboard of OSB admin console then collects stats data using JMX(as described in previous link) hourly using WebLogic Server JMX Timer Service as described in
http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jmxinst/timer.html instead of Java's Timer class.
Not sure if this is the best practice.
Thanks,
Regards,
Sam

Using JMX and MBeans

I've been experimenting with Java instrumentation with MBeans.
I created a small app to try out some of the JMX features. The app has a class that I would like to monitor with MBeans. So I created to interfaces to function as MBeans and then had the class in my app implement both interfaces.
I then wrote a class with only a main() method to instantiate my class and call the methods it implemented from my MBean interface. In the main method I provided the code to get an MBeanServer object and then use that to register my class that implemented the MBean interfaces. My intention was to try this out, but before I did I commented out the code needed to register the class with the MBean server. I did this because I assumed the implemented interface methods would be available for monitoring without registering and it made me think if I can monitor the instrumented class like this why would I need the MBean server.
So what is the purpose of the JMX framework and MBeans if I can instrument any class as described above?
Is it necessary to register only to be able to monitor from outside the JMV where the instrumented class is running?
Or are there other advantages\features\reasons for registering with the MBean server?
Thanks

Deployment of .war file using JMX in jboss 4.0.5 GA

Hi,
Can anyone help me out in the steps of deployment of .war file using JMX in JBOSS 4.0.5 server.I went through the documentation in jboss.org but couldn't find a suitable one though there were many.Any links/url that you know about the deployment process will also be helpful to me.
Thanks

You're probably using an older version of JavaMail where there was a bug in the example
DummySSLSocketFactory. Download the latest version and the example is correct.
Also, if you're using DummySSLSocketFactory just to control which servers you trust,
JavaMail 1.4.3 has some properties that will make this easier for you and avoid the need
for DummySSLSocketFactory. In particular, see the mail.imaps.ssl.trust property.

Problem to connect to mdb using java on solaris 10

hello I'm trying to connect to my mdb using the code below
String database = "/export/home/test.mdb"; String url = "jdbc:odbc:DRIVER={Microsoft Access Driver(*.mdb)};DBQ="+ database+ ";DriverID=22;READONLY=false"; try { Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); conn = DriverManager.getConnection(url); } catch (Exception e) { System.out.println(e.getMessage()); } finally { if (conn != null) { try { conn.close (); } catch (Exception e) { /* ignore close errors */ } } }
the javac returns no errors, but when I'm trying to run the program "null" is printed ( I think that is the e.getMessage). I supose that conn is null and I don't know why. I'm sure that test.mdb exists and it is located to /export/home. I think the problem is that I haven't install an odbc driver on solaris for mdb I don't know where to find it (if anyone can give me a link !!!), but I'm not so sure if this is the problem.
help me please
thanks in advance.

Joe, I know that you are a skeptic, and need proof for everything said. I heard about the demise of Access, or more correctly the database most frequently associated with the Access front end, JET, several years ago from a Microsoft employee. Yet it is still here.
There is plenty of documentation online about this. Here's just one example: http://www.answers.com/topic/microsoft-jet-database-engine?cat=technology. MS themselves are rather less clear.
That link would suggest that MS Access 2007 is not in fact SQL Server.
MS has been trying for at least 5 years to wean its users off Access-JET and onto one flavour or another of SQL/Server. I'm a Microsoft Partner and see their marketing on a regular basis. Access is rarely mentioned and SQL Server is a hot topic. Note that most MS/Office applications, such as Outlook now use SQL/Server.Ok.
However marketing is different than technology. In terms of that I can only note that I don't see Bob on my desktop.
And Office 2007 is still using Access (which apparently is not SQL Server according to what you posted.)
Conversely, for example, Microsoft has specifically announced that FoxPro will no longer be supported.
Thus I am still looking for something that would suggest that either it is SQL Server right now (2007) or that it shortly will be - like perhaps the beta for the next version is.
And I can only note that some of the stuff that Access does would be difficult to seamlessly do via SQL Server. The article that you posted suggests that upgrades from MS Access exist but that those can lose functionality that will require manual work to replace. Thus if MS did decide to replace Access in Office with SQL Server they would need to come up with a solution for that or risk people not upgrading.
I am not claiming that this can't happen but rather that I question whether it is relevant to suggest that it anything of concern in the near future (especially for an app that is targeting it anyways.)

Weblogic.security.service.NotYetInitializedException using JMX

Hi there,
I'm trying to use JMX to add a notification listener to listen for attribute changes to a WLS 8.1 MBean. My code when setting up the listener is as so:
String url = "t3://localhost:7001";
String serverName = "Server1";
String userName = "weblogic";
String password = "weblogic";
MBeanHome home = null;
RemoteMBeanServer rmbs = null;
Environment env = new Environment();
env.setProviderUrl(url);
env.setSecurityPrincipal(userName);
env.setSecurityCredentials(password);
try {
     Context ctx = env.getInitialContext();
     home = (MBeanHome) ctx.lookup(MBeanHome.ADMIN_JNDI_NAME);
} catch (NamingException e) {
     e.printStackTrace();
rmbs = home.getMBeanServer();
WLListener listener = new WLListener();
WebLogicObjectName mbeanName = new WebLogicObjectName("examplesServer", "Server", "examples");
rmbs.addNotificationListener(mbeanName, listener, null, null);This seems to work fine, I do not get any error messages. As you can see I'm using the server started through the examples, and I'm adding a notification listener to the ServerMBean.
My notification listener code is as so:
public void handleNotification(Notification notification, Object arg1) {
     AttributeChangeNotification changedAttrib = (AttributeChangeNotification) notification;
     try {
          System.out.println("Changed value from: " + changedAttrib.getOldValue() + " to " + changedAttrib.getNewValue());
     } catch (Exception ex) {
          ex.printStackTrace();
public boolean isNotificationEnabled(Notification arg0) {

How to use JMX

Hi, all,
I am newbie in JMX. I want to know what software,such as API and so on, i must need to use JMX .and I want some tutorials of JMX.
thanks.
Kaven

Check out the JMX listserv archives at
http://archives.java.sun.com
and look for JMX-FORUM.
Theres information in there, and coincidentally over that last two days people have been asking the exact same question - look for the replies to topic "help ... get me started" - lots of links there.
There is also the sun JMX home page.
There are a few commercial implementations of JMX and at least 2 open source ones - search the JMX-FORUM for "open" if you're interested in that. Plus Sun supplies a reference implementation ( although I haven't used that.)
Personally I use JDMK, Sun's implementation, and I've found it meets my needs ( but then I'm not paying for the licence, my company is.) and it is available as an evaluation copy before you buy. It comes with tutorials, but I wouldn't be surprised if the others do as well.
Try and search the sun site and google for JMX, there'll be stuff there.
Finally, go to Amazon.com and look for "java and jmx" - there is at least one book out there.

Starting/stoping java app using JMX ?

Hello, do any one know, whether we can start / stop java application using JMX ? I know it is monitoring api and can help to find whether app is up or down

I see the same error when I start domain1. However, I was able to deploy and configure Access Manager 7.1 using the WAR file method, as described in Sun Java System Access Manager 7.1 Postinstallation Guide, page 153. The Guide's instructions are for Sun Java System Application Server Enterprise Edition 8.2, but they seem to work okay with version 9.1. After deploying the WAR file, the Configurator comes up automatically the first time you browse to its URL, typically http://localhost:8080/amserver.

Basic MIB and SNMP understanding using JMX

i am trying to get my head around SNMP using JMX, but i am finding it dificult to know where to start.
ideally i would love to find some basic code and go through it, so that i can understand it.
i would love to find some code which just "Gets" one parameter from a mib stored on a seperate PC and displays it on another PC.
I have looked at advent - to complex for what i want.
Any help or suggestions - or possibly Code!! would be appreciated.

There is an example code included in the upcoming book "JMX: Managing J2EE with Java Management Extensions" that shows how to retrieve a simple attribute value from an JMX SNMP Adaptor using the Sun JDMK and AdventNet SNMP toolkits. It's a brief introduction to SNMP integration but should get you started.

Unfortunately you still have to wait a week or two to get it.
Basically the examples show how you can generate the required MBeans from an SNMP MIB definition (in Sun's JDMK this is a tool called MibGen), then register the SNMP Adaptor to the MBean server and associate and register the MBeans that were generated from the MIB to the adaptor. You can then use an SNMP client to connect to the adaptor and manipulate the MBeans through SNMP.
Hope this is of some help.
