JMS/WS connection locks

Hello!
I have next configuration:
ws client <- -> service (soap/http) <- -> osb business service <- one-way ssl -> ws provider (basic authentification)
jms client <- -> service (soap/jms) <- -^
Problem:
If run load test ws client - service work fine, but if in moment this test jms client send message then ws service and jms service have locks by 2 min.
ThreadStackDump contains:
"[ACTIVE] ExecuteThread: '39' for queue: 'weblogic.kernel.Default (self-tuning)'" waiting for lock java.util.Vector@6a692986 BLOCKED
                 java.util.Vector.isEmpty(Vector.java:279)
                 weblogic.net.http.KeepAliveCache.get(KeepAliveCache.java:150)
                 weblogic.net.http.HttpClient.findInCache(HttpClient.java:230)
                 weblogic.net.http.HttpsClient.New(HttpsClient.java:499)
                 weblogic.net.http.HttpsURLConnection.connect(HttpsURLConnection.java:239)If don't use ssl then problem go away.
Do you have ideas about problem?
Thanks

I don't know what the issue might be, or whether it involves JMS per se. Check for pools in your thread dump that appear to be completely used up - this situation can lead to having no new threads to process new work or to wake up sleeping threads. It might help to post more detail -- full stack dumps for the blocked JMS, WS, and HTTP threads, or, better yet, the full thread dump. You might also want to try posting to one of these newsgroups:
* WebLogic Server - Web Services
* WebLogic Server - WebApp / Servlet / JSP / Plugin

The above is the jrockit crash dump file..
I am using the JMS Wrapper Connection Poooling provided by Weblogic. When i use Jmeter and do the load testing for around 10 users, the server gets crashed.
I doubt something is going wrong with the Weblogic JMS Connection Pooling, please help me..

The problem doesn't look like it has anything to do with wappers per se. The stack indicates that the JVM died when the persistent store tried to invoke a standard Java synchronize operation. JVM crashes need to be analyzed by a JVM expert, so I second the suggestion to solicit help from JVM experts and/or filing a case with customer support. In the mean-time, you can probably work-around the issue by either (A) ensuring you have a recent version of the JVM installed, or (B) temporarily switching to the Sun JVM.
Regards,
tom

Hi,
Maybe this is caused by the Vector is synchronized instead of the List, if so there is this limitation in the WLS http connection. Not sure whether you can use the JDK https connection instead:
System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");

PI7.1 JMS Adapter - connect to NW6.40

Hello,
We are facing following problem on SAP PI:
We have a scenario where PI (version 7.1) is connecting to another SAP NetWeaver system (version 6.40). There is an application that reads/puts messages from/to JMS Queues running on this system. PI has to connect the JMS Provider of 6.40 system and read/put these messages from/to these JMS Queues.
This scenario worked fine till we used XI 3.0 (NW6.40). We configured sender JMS channel with link to remote JMS Server and parameter "force_remote".
After installation of new PI7.1 we noticed some issues:
1.the connection is unstable. Sending JMS messages from PI to NW6.40 queue works a while but then we get error like this:
Adapter Framework caught exception: Unable to write new JMS message body for message: 00237d29-13fc-02ed-ba85-01d046631592: ConnectorException: Connector for ConnectionProfile of channel: EON_CC_jms_rcv_omsmessageon node: 922834950 having object id: 70855b1c6c483e869982ea2fe9787b36 was unable to create a new javax.jms.TextMessage message: javax.jms.IllegalStateException: Session is closed.
2. we cannot read messages from JMS Queue of NW6.40 at all. The messages are there in queue, communication channel is running and succesfully connected to queue but no message is processed and no error shows in communication channel monitoring.
Has anybody solve similar problem with connection between 7.1 and 6.40 NetWeaver?
I think the problem can be backward incompatibility of 7.1 SAP JMS libraries against 6.40. If this is true then the question is whether it is possible to deploy old libraries and run them simultaneously with native 7.1 libraries?
Thanks

problem sorted - factory property settings were not configured correctly in JMS Adapter connection pool

Using JMS to connect to Sun's 1.4 J2EE server

Hi,
I've been reading around various postings detailing how to connect to J2EE servers at runtime, and they all seem to follow the format:
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.enterprise.naming.SerialInitContextFactory");
props.put(Context.PROVIDER_URL, "rmi://localhost");
// Create a JNDI API InitialContext object
// (may throw a NamingException)
jndiContext = new InitialContext(props);
But none of the discussion is totally complete. It seems incredibly difficult to connect to a J2EE server, and the documentation on the issue is incredibly poor.
I'd like to do this without the 'appclient' program that comes with Sun's J2EE server as I wish to have a development environment that can start up, connect to the J2EE server, and send messages.
So has anyone managed to get this to work?
I'm confused to where the username and password go. I've seen other suggestions to make the above work, including:
props.put("org.omg.CORBA.ORBInitialPort", "3700");
props.put("org.omg.CORBA.ORBInitialHost", "localhost");
ORB orb = ORB.init(new String[] {}, props);
props.put("java.naming.corba.orb", orb);
Therefore can anyone clear this up for me! A few lines of code, showing exactly how I can connect to a J2EE server.
All I want to do is send a few messages.. :)
Cheers
John

I tried everything in this form but I could not send a message to queue from my standalone client.
I am trying to communicate with my application server throught JMS almost a week. But I could not get any result. I even read twice some forms. Actually all I can say I progressed to here..
My code is below...
Context initialContext = new InitialContext();
            javax.jms.QueueConnectionFactory factory = (javax.jms.QueueConnectionFactory) initialContext.lookup("jmsFactory");

Javax.jms: Interface Connection

Hi all.
In the above interface is said:
"A Connection object is a client's active connection to its JMS provider. It typically allocates provider resources outside the Java virtual machine (JVM). "
What does this part exactly mean?
"It typically allocates provider resources outside the Java virtual machine (JVM)."
Thanks in advance.

Can you also help me on this please; I have this piece of code; factory is an object of type: progress.message.jclient.ConnectionFactory
Then createConnection() returns an object of type: Connection: javax.jms Interface Connection
But shouldn't Connection be a class and not an interface?
Any help is greatly appreciated.

HP Laserjet m602 firmware upgrade successful_network connection locks up printer

Our laserjet m602dn control panel displayed that a firmware update was successful, but connecting the ethernet cable to the printer locks it up. The update removed a blinking amber attention light (on control panel) that kept the printer from going into "Ready" mode.
After the firmware update, the printer displays "Ready"; printing works through a local connection; pinging to the ip address fails. Can a firmware update be successful on a defective jetdirect/formatter board? If the board is defective, why does a local connection work?
Are there any known issues with the following part: CE988-67906?
Thank you.
JP

JP_VA,
I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial printer. You can do this at http://h30499.www3.hp.com/hpeb/ .
I hope this helps.

Error with the Receiver JMS Adapter (Connection On-Demand feature)

Hi,
In high volume we are experiencing errors with the Receiver JMS Adapter and the connection On-demand feature:
Adapter Framework caught exception: while trying to invoke the method com.sap.aii.adapter.jms.api.connector.DisconnectorListener.notifyEvent(java.lang.String) of an object loaded from local variable 'listener'
Delivering the message to the application using connection JMS_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: while trying to invoke the method com.sap.aii.adapter.jms.api.connector.DisconnectorListener.notifyEvent(java.lang.String) of an object loaded from local variable 'listener'.
The message status was set to WAIT.
Looks like the message is successfuly reprocess after the wait period but the ALEAUD/Akcnowledgment are not successful in the sender ECC system. (SAP -> PI - > JMS)
Any idea?
PI 7.1 EHP1
Thanks,
Martin

HELP: Connectivity locked up problem

Firstly I am sorry about I don't know this is the right place to post this thread...
I have a Nokia 5800 Xpressmusic. And I have a problem with it. When I tap into "Menu-Settings-Connectivity" and try to exit from there my "Settings" menu locked up. It shows that "Settings" menu always running background. And I can't tap anymore "Settings" menu until restart my phone. How can I resolve this problem?

I write my step by step and i attached two pictures to understand my problem easily.
And please replace extension to jpg from txt.
1) I tap menu button and it opens menu. (picture 5800mainmenu.jpg) but for now ignore red circle in the picture.
2) Then I tap "Settings" from main menu and it opens settings for phone (picture 28.jpg)
3) Then I tap "Connectivity" from settings menu and it opens another menu. (I couldn't attach third picture. sorry for that)
4) I tap "Exit" from "Connectivity" and it don't. It partially locked up. I mean i can't use "Settings" menu if dont restart my phone. It always show busy "Settings" menu like in picture 1 that marked with red circle.
I hope it would be more understandable...

Connecting locked ipod to new computer

I have a 2nd generation ipod touch that is locked and the screen say connect to itunes. When I connect to my mac, itunes doesn't recognize the ipod because this computer is not the original computer that it was synced to. How can I reset the ipod and the passcode?

From http://support.apple.com/kb/HT1212
If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone and iPod touch software: http://support.apple.com/kb/HT1414

Connecting lock-in amplifier to USB-6009/6211

I am working on re-setting up a labview environment in the lab I work at. We are using a SR810 DSP lock-in amplifier and want to bring the data into labview. The labview code says that in the past we used a USB-6009 to read in data from the lock-in amplifier. The output ports on the lock-in are an RS232(DCE), a IEEE-488 port, and a preamp port. Is there someway to feed one of these outputs into the DAQ that we have. Thanks

An RS232 or GPIB connection directly to the computer would be best, but if you insist on using the 6009, run a line from the CH1 outut BNC on the front panel of the lockin into the DAQ device. Note that this is a -10 to 10 V output and that the mapping to the actual LIA voltage depends on the sensitivity setting of the lockin (see pgs 4-2 and 4-12 of the 810 manual).

OCI connection Locked

Hi Guys:
I have a Server application in C++. This application connects with Oracle DataBase (9.2.0.5). The application fork in 8 child process, and each one keep a connection with the database. But after several transactions received and update in the DB, the child process is locked waiting for answer from oracle.
I think is init.ora issue. Could anybody guide me with that?
Thanks a lot.

Hi,
Does each of the child processes do a commit after having done their part of insert/updates. There is every likelihood of processes waiting for a particular row to get unlocked (which happens only on a commit).
Thanks
Sumit

JMS active connections to MQ Series

Hi There,
Is there any algorithm to calculate MDB's active connections opened to MQ?
Thanks in advance,
Naveen

The number of connections to MQ depends on the number of threads that your MDB uses
if yourMDB is configured to run with a custom work manager , than the easy way to track the number of connections is to monitor the number of thread scheduled to run the MDB insatances
also , if your MDB is using the JMSWrapper (foreign JMS server ) than you can monitor the number of jmsdispatcher threads
