Suspending JMS event generator
Hi,
How do I suspend a jms event dynamically?
I know that this can be done with WLI Admin Console but is there another way to do this without user intervention?
Help appreciated.
Hello,
event generators are in most cases EJBs (the HTTP event generator may be the only exeption).
Suspending is actually equal to undeploying.
I do not know, if you can use the event generator MBeans, but you can always use the weblogic.Admin command to undeploy/redeploy a JMS event generator.

JMS event generator extract custom jms property
[cross posted from integration.interest - this seems the correct place to post]
Hi, I was looking for a way to enable a workflow/process to extact a custom jms property that is send with a jms message to the jms event generator.
So the client inserts name/value pair inside the jms message, the event generator picks up the message and starts a workflow. How can I extract that custom name/value pair once inside the workflow/process ?
TIAHey can u tell me the solution for this problem.....I am also facing similar problems......Help is appericiated....

WLI 10g3 JMS Event Generator for Foreign Queues
Hi,
Our requirement is to listen to messages on a remote destination on another weblogic instance (8.1).
One option we are trying is create a foreign JMS Module on local server (10g3) to connect to the remote destination
and use JMS Event Generator to poll for messages on the local Foreign JMS Module and fetch the message and publish this
message into a message channel.
This works fine when I have a local JMS Queue and JMS Event Generator tries to listen to it.
But while trying to use JMS Event Generator against foreign JMS module we are getting stuck with error failed to establish JMS Session :
<Jul 8, 2009 12:26:29 PM IST> <Warning> <EJB> <BEA-010096> <The Message-Driven EJB: foreignGenEventName is unable to connect to the JMS destination or bind to JCA resource adapter: test.mydestination.

Any pointers to a possible issue will eb really helpful.
Thanks,
CAVarun,
Thanks for your inputs. Regarding the possibility of misconfiguring the ForeignJMSServer , we are able to view the remote destinationname (also the jndi binding name) in the jndi tree of the local server console, which in my opinion translates to a valid configuration.
Can anyone let me know if this issue is fixed in 10.3 as there is a CR raised in the 10.0 version as well for this?
CR332983
CR326377 It was not possible to deploy an MDB while connecting to a foreign JMS provider through WLS foreign server resources configured in a JMS module.

JMS event generator only gets non-transactional queue msg
Hi,
I have created a JMS event generator to listen to a particular queue. It seems to work perfectly fine if, when posting a message to the queue that the JMS EG is listening to, the queue created is a non-transactional queue, i.e. queueConnection.createQueueSession(false, ...).
However if I created a transactional queue to post message to the JMS EG, i.e. queueConnection.createQueueSession(true, ...), then the JMS EG can't seem to see the message. I checked in the WLI Admin console, JMS EG section, and there are no messages read by the particular JMS EG after I have posted the msg to the queue.
My question is: is there a known limitation on the JMS EG that it can only read from a non-transactional JMS queue, or is this a bug? (I am using weblogic 8.1 sp2).
Thanks
Regards,
xlfhkHi,
sorry, just discovered it's my mistake. Instead of using the transaction created when calling queueConnection.createQueueSession(true, ...), and committing that, I created a JTA transaction artificially wrapping the entire chunk of code.
As a result, I ended up with a pair of transactions that are nested (I think ...), and the external transaction's commit was called when the nested JMS transaction hasn't been committed yet. As a result, no commit ever took place (I think again ...).
I have now tried calling queueSession.commit() after sending the message. It seems to work fine. Thanks for the help.
Regards,
xlfhk. -
MapMessage and JMS Event Generator
Hello
I need to set up a WLI JMS event generator that will consume a JMS MapMessage. It appears that the only message types supported by a JMS event generator are xml, rawData, string and none.
I've already tried each of these and for each I get a message saying "Cannot publish non-TextMessage to channel of type String" or "Cannot publish non-ByteMessage to channel of type ...".
I have sent MapMessage types using WLI's JMS controls. Is there a way to consume a MapMessage type via an event generator?
Thanks
TomBishu thanks, Channel type is defined as String, Message on JMS queue are of type String. Also can you elaborate on "JMS event generator check the type of message you want to process." that you mentioned. I have not found this option while configuring JMS EG. (We are using ver. 8.1 sp 5)
This was working fine in local env. But when we configured message bridge between MQ queue and JMS queue, we startted getting error messages. I am trying to find out how does MQ stores messages. Doing integrations with MQ has been real headache for us. -
JMS event generator accepts messages, but won't push out to channels
I am monitoring the JMS event generator through the WLIconsole, and I can see the
messages coming in. I have a channel rule defined for this particular event generator
- it just allows everything through (by leaving the name and value fields blank).
I can see that there is a channel listed under the channel count.
However, when I go under the Message Broker window, and check the channel, there
are zero subscribers. This is probably why the messages that are going into
the generator aren't being recieved by anyone.
I'm trying to use this channel to kick off a workflow - so the event choice start
node is set to listen to a channel, but I don't think it actually subscribes to
the channel - if it did, why wouldn't it be listed under the WLI console as a
subscriber? How do I get the start node to listen to the channel? How do I get
the messages from the event generator into the channel?Hello MS, Question: Do any of the LED lights on the keyboard turn on when the computer doesn’t boot? Here’s an HP troubleshooting document for notebooks that won’t start, along with some info about LED error codes: http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c01732674 If that doesn’t help, it is probably a hardware issue.

Hi,
I have created a durable topic and an event generator to listen this topic.
I got functionality to suspend this topic to start execution of some process and then resume back when it process finished.
Meanwhile other application keep on publishing messages to the topic and it is expected that when event generator is running is should pick up the message from the topic.
But it is not happening it does pick any subsequent message published to topic but not picking up old message.
Can any body what is wrong happening?
Regards,
JugalYou cannot. The message broker puts the message into the dispatcher queue of the process web application, so it is a JMS message, but the workflow receives it as xml, string or rawData object.
What do you want to achieve ? Only MB client is a JPD and there is no (obvious) use for JMS messages.

Problem with creation of the jms event generator
hi,
I have set up a weblogic workshop instance on one of my machines. It has a queue call OUT.QUEUE. The application writes message to this queue. I have set up an integration instance on another machine. I have created a Foreign JMS server to point to the first machine. I have also configured a queue which points to the one on the first machine. However when my integration server starts up, I keep getting the error.

I need a transaction from the MDB since I am not using an EJb to pursue the action.
Hence I need to retain the <trans-attribute>Required</trans-attribute> at the

It's resolved.
The MDB automatically created by JMS Event Generator defaults to be deployed
with
“transacted”. That requires the foreign JMS provider to be “XA”.
The deployment descriptor is created as <domain-directory>/WLIJmsEG_<event_gen_name>.jar
e.g. C:\bea812\user_projects\domains\jmsInterop\WLIJmsEG_mqQueueEventGen.jar
Since MQ in the localhost and remote SLUDV18 are not XA-enabled, we had
to manually
change the <container-transaction> section in ejb-jar.xml:
From :
<trans-attribute>Required</trans-attribute>
To:
<trans-attribute>NotSupported</trans-attribute>

JMX API to Create Event Generator
Is there any JMX API available to create JMS event generator?
ThanksHi,
As mentioned in the last post go to the event screen by
Environment --> Modifications --> Events.
There you click on new entries and try writing your logic for event 21 i.e. after selecting 21 give some name of your event and write down the logic how you want to do this.
If event number 21 does not work then try 1. One of these two should work.
Hope this helps!!!

Hi there
I'm developing an process application for which i have configured two
timed and a jms event generator. The question I have is, is it possible
to export event generator configurations from my dev box and simply
import them into wliconsole on my prod box? Or do i have to manually
configure the prod box with the same configuration?
Regards
SteriHi Jaime,
I have two even servers. But the monitoring thing and the events that you are talking about is completely different.
There are events in the event section of the CMC .
I checked the things on the old XIR2 environment. The events in the Event section and the ones that are being monitored by the Event Server are different.
So being a fool i dont know how to get those files to be monitored.
Let me explain what i understood.
1. There are some files in some location which are being monitored.
2. When an ETL runs the file is supposedly refreshed.
3. This refresh leads to may be some event which is monitored by the event server and then based on this some reports run.
So how to enable the Event server to monitor those locations.
Regards

Greetings:
I have a MQ Event generator that subscribes to a qlocal and publishes messages onto a channel read by a business process.
I need to process around 10 messages a second syncronously through this process (fifo), judging by the process instance monitoring I am able to process most transactions in <.1 seconds. However, it doesn't seem like the event generator is polling/publishing fast enough to fully utilize the efficiency of the process. I routinely have thousands of messages backing up on the queue awaiting processing. I have tried different configurable params on the event generator (500 messages every 10 seconds, 1 msg every 100 msecs etc) to no avail... i still only seem to be pulling one message in just under a second.
I'm wondering where I can tune this piece of the application. All my threads seem pretty free etc...
Any help would be greatly appreciated. Thanks!Suspending / resuming event generators is nothing else then undeploying /redeploying the component, which is building up the event generator (either a MDB or a servlet). That can be done via the JMX Api.
If you are using Timer events , you have to do that inside a workflow. A cron job calling a script could do that less resource intensive (or use whatever scheduling system which is available like Control-M ...)
Be also aware that WLI timers are JMS based, so an event is only guaranteed to be raised not before the scheduled time, but maybe not exactly at the scheduled time.

Okay to use both Exposure and Levels?
Is it okay to routinely use both the exposure settings (exposure, recovery, black point, and brightness) and levels on the same image? I feel that since they overlap in function, I would be canceling or negating the effect of one if I use the other.
