Publish subscribe model with plsql

Hi,
I did not find any sample that shows how to use the publish subscribe model with plsql.
Enqueueing is possible and know how to do it, but how can I subscribe to a topic with plsql.
All samples I found are for Java JMS.
Thanks
Günther

Hello,
I have assumed you are using 10.2
There are examples in
http://download.oracle.com/docs/cd/B19306_01/server.102/b14257/toc.htm
about using multi-consumer queues/topics. There are demos in $ORACLE_HOME/rdbms/demo if you have installed the companion cd.
Thanks

Publish Subscribe Server with Filters

Has anyone managed to get the WebLogic Server 10.3 HTTP Publish/Subscribe server to work with message filters?
With a message filter configured, running with the Sun JVM I see errors of the following type (JRockit gives an error at the same point but it has less information) when I send a message via JMS:
<02-Sep-2008 10:43:23 o'clock BST> <Warning> <HTTP Pubsub Server JMS support> <BEA-2152103> <Error occurs when retrieving message from JMS topic.

My filter is not being invoked (I just throw an exception in the filter and I've also tried setting a breakpoint there in debug mode and neither get hit).
My weblogic-pubsub contains the following:
<wlps:message-filter>
<wlps:message-filter-name>myFilter</wlps:message-filter-name>
<wlps:message-filter-class>pubsubtest.filters.SecurityFilter</wlps:message-filter-class>
</wlps:message-filter>

<wlps:jms-handler-name>abcJmsHandler</wlps:jms-handler-name>
<wlps:message-filter>myFilter</wlps:message-filter>
</wlps:channel>
The class name is definitely correct because the app fails to publish entirely if it is not. I have the pubsub library referenced in my weblogic.xml and it works without the filter so that suggests that the pubsub server is deployed.
Anyone have any ideas?
-Shaun

I'm not familiar with HTTP pub/sub.
My one guess is that the server is attempting to deserialize an Object that's embedded within a JMS Object message, but the classpath is missing required classes in order to instantantiate the Object. In which case the solution is to ensure that the classpath includes any classes that might be embedded within the message object.
If this doesn't help, can you post the full stack trace? The posted stack trace is truncated but the full trace should be in the log, as per the message "Truncated. see log file for complete stacktrace".

Publish data model with designer

Hi,
so far I used ERwin for data modelling. ERwin can generate HTML output consisting of the graphical data model plus hyperlinks on the tables. If you click on a table a report pops up with all details, e.g. table and column comments.
I find this very useful to publish the data model.
Is there something similar available with Oracle Designer?
I found this announcement, but no product: http://otn.oracle.com/products/designer/pdf/ROB_Announce.pdf
Best Regards,
Jens

If you have any recent release of Designer installed, then you have the ROB automatically installed. Select your Start menu in Windows and then navigate through your menus to the Designer sub menu and you'll see a link for setting up the ROB.
The ROB was made available as part of Designer from March 2003. The lastest release of Designer, viz Designer 10g (9.0.4.4) and the equivalent 9i and 6i releases, all now avialable on OTN, have additional support for the ROB. This offers the ability to save and ERD or Server Model Diagram directly to the ROB.
You do need to add the "hotpost" functionality manually. The ROB help gives a step by step apporach on adding these hotspots. There are a number of demos on the Designer demo page on using the ROB and configuring the App Server to use it. http://otn.oracle.com/products/designer/demos.htm

Interactive SAP GUI Application - Publish-Subscribe Model

Customers want to pay for such interactive applications: SAP GUI subscribes to external events, provides visual feedback for these events, and popups other screens related to events. And all this without user action (almost:).
From my preliminary investigations, SAP implements https://www.sdn.sap.com/irj/sdn?rid=/webcontent/uuid/04291088-0901-0010-ebab-ccfd2c848355">web [original link is broken] [original link is broken] but this is a reference to the standards only without any clues how this is related to SAP GUI applications. What techniques has been really and successfully used?
Sharing your experience writing interactive application will be greatly appreciated.

You can deploy both Applications and Packages using the Application Catalog.
Just make sure to target a user collection.
Deploy to users as "Avaliable" and it will show up in the Application Catalog.

¿How can I publish a Camera with a different UserID?

First of all, Happy New Year 2011!
I've tried WebcamPublisher webCamPub.publish("userPublisher") method to publish a WebCam to a room with a different user that the "myUserId" logged at the session, but the subscribers attached to the room they never receive the video. If I check the Room console I can see the new user has been created and the camera stream assigned. If i use the normal Publisher-Subscriber example with webCamPub.publish() everything works correctly. One difference, on the normal example when I publish the Publisher, the Flash Player Configuration will ask me permision to access the Camera, but on my new code i will never be asked for this access. It looks like if a Camera start is needed to be executed. ¿What am i missing?
Here is my specific code
 private function onCreationComplete():void
 cSession.roomManager.autoPromote = true ;
 cSession.roomManager.guestsHaveToKnock = false ;
 userPub1= new UserDescriptor();
 userPub1.userID="userPublisher";
 userPub1.displayName="userPublisher";
 userPub1.role=100; //Tried also with 50 obtaining the same behaviour
 cSession.userManager.createUser(userPub1);
 sharedProperty = new SharedProperty();
 sharedProperty.isSessionDependent = true ;
 sharedProperty.sharedID = "webcamShare" ;
 sharedProperty.connectSession = cSession ;
 sharedProperty.subscribe();
 sharedProperty.addEventListener(SharedPropertyEvent.CHANGE,onChange);
I've tried to create the Publisher on two different methods.
 private function onChange(p_evt:SharedPropertyEvent):void
 if ( webCamPub != null ) {
 webCamPub.close();
 webCamPub. = null ;
 webCamPub = new WebcamPublisher();
 webCamPub.connectSession=cSession;
 webCamPub.sharedID="webcamShare";
 webCamPub.publish("userPublisher");
 private function onBtnClick(p_evt:MouseEvent):void
 if ( p_evt.currentTarget.label == "Start" ) {
 webCamPub.connectSession=cSession;
 webCamPub.sharedID="webcamShare";
 webCamPub.publish("userPublisher");
 webCamPub.initialize();
Here also is a part of the code of the Webcam example that is working ok.
if ( p_evt.currentTarget.label == "Start" ) {
 webCamPub.connectSession=cSession;
 webCamPub.sharedID="webcamShare";
 webCamPub.publish();
<rtc:ConnectSessionContainer id="cSession" authenticator="{auth}" width="100%"

 <mx:VBox id="vbox1" width="100%" height="15%" horizontalAlign="center" horizontalGap="5">

 </mx:VBox>
 </mx:Repeater>

 </mx:Panel>
</rtc:ConnectSessionContainer>
I can attach my complete code if you think is usefull. Thanks in advance.

PLSQL Notification on a multi-subscriber queue with sys.aq$_jms_text_messag

Hi all,
I am trying to get PLSQL notification working on a multi subscriber queue with sys.aq$jms_text_message as the payload type. The commands to create my queue are as follows:
dbms_aqadm.create_queue_table(
queue_table => 'SOA_JMS.RJMTESTxx_QTAB',
multiple_consumers => true,
queue_payload_type => 'sys.aq$_jms_text_message'
dbms_aqadm.create_queue(
queue_name=>'RJMTESTQ',
queue_table => 'SOA_JMS.RJMTESTxx_QTAB',
retention_time => 86400, --Keep processed messages for 24 hours
max_retries => 3,
retry_delay => 1
dbms_aqadm.start_queue('RJMTESTQ');
dbms_aqadm.add_subscriber(
queue_name => 'SOA_JMS.RJMTESTQ',
subscriber => sys.aq$_agent('SUBSCRIP1',null,0),
rule => NULL,
transformation => NULL,
queue_to_queue => FALSE,
delivery_mode => dbms_aqadm.persistent
I then create a procedure with the following signature:
create or replace procedure SOA_JMS.EXCEPTION_QUEUE_NOFIFYCB_1(
p_context in raw,
p_reginfo in sys.aq$_reg_info,
p_descr in sys.aq$_descriptor,
p_payload in raw,
p_payloadl in number
And register it as follows:
reginfo := sys.aq$_reg_info(
'SOA_JMS.RJMTESTQ:SUBSCRIP1',
DBMS_AQ.NAMESPACE_AQ,
'plsql://SOA_JMS.EXCEPTION_QUEUE_NOFIFYCB_1?PR=0',
--utl_raw.cast_to_raw('STANDARDJMS')
HEXTORAW('FF')
reg_list := sys.aq$_reg_info_list(reginfo);
dbms_aq.register(reg_list,1);
The problem is the notifications are not firing as they should be.
I have done some tracing and found an error:
Error in PLSQL notification of msgid:BA964334E5A057A4E040C69BAF397075
Queue :"SOA_JMS"."RJMTESTQ"
Consumer Name :SUBSCRIP1
PLSQL function :SOA_JMS.EXCEPTION_QUEUE_NOFIFYCB_1
: Exception Occured, Error msg:
ORA-00604: error occurred at recursive SQL level 2
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'EXCEPTION_QUEUE_NOFIFYCB_1'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
This says that the parameters I have for my procedure is wrong. Looking through the documents I think it is something to do with the ?PR=0 used in the register call, but I can’t find any documentation telling me what the required parameters are.
Does anyone here know?
Thanks
Robert

Hi,
I have found the solution and I am posting here in case it helps anyone else.
The paramater names must match the callback not just the types and in/out.
So the following works:
create or replace procedure SOA_JMS.EXCEPTION_QUEUE_NOFIFYCB_2(
context in raw,
reginfo in sys.aq$_reg_info,
descr in sys.aq$_descriptor,
payload in raw,
payloadl in number

Can anyone tell me what is "publish and subscribe model"?

hi experts:
can anyone tell me what is "publish and subscribe model" in detail?

Publish-Subscribe Model
Purpose
This model defines how you publish messages to and receive messages from a well-known node. Such nodes are referred to as topics. You can use the model for:
·        Creating Message Producer to a Topic
·        Creating Message Consumer to a Topic
·        Managing Durable Subscriptions
Chk this for more.

Asynchronous Publish Subscribe with Session.Client_Acknowledge

Is it possible to do Asynchronous Publish Subscribe with Session.Client_Acknowledge in JMS? If no, then is there any way to acknowledge each message in an Asynchronous Publish Subscribe application?
Any code samples will be helpful..
Thanks in Advance,
Jo

CLIENT_ACKNOWLEDGE does work in asynchronous mode.
I am using Sonic MQ. The sending session is created with CLIENT_ACKNOWLEDGE, in my onMessage(), I am testing the acknowledgement as:
if ( 1 == 2) msg.acknowledge();
else {
Thread.sleep(1000);
sendsession.recover();
Since the condition is never true, the message is never acknowledged by the receiver and stays in the queue all the time.
The confusing point: If you don't call the recover() function and your receiver is running, there would be no more messages to consume. As for SonicMQ, refreshing the Explorer will also show the number of messages in the queue is 0. However, if you Ctrl-C your receiver or call the sendsession.recover(), then you'll find out that the messsages are still in the queue by running the receiving program again or refreshing the queue.
However, the behavior of this may be vendor-dependent. I am just happy that Sonic MQ is doing what I expect.

Publish subscribe with XI

How do u do publish subscribe with XI? I dont see that in XI as opposed to webMethods or TIBCO. Any thoughts?
gayatri

Hi,
To my knowledge XI dose'nt work on the principle of Publish and Subscribe. XI is Message Driven rather then Event driven. But still we can make even driven message processing but that dose'nt fall under Publish and Subscribe.

Need to "publish/subscribe" my Contacts info like we could in Addressbook. Any ideas?

Being a LONG TIME Mac User (yes, I owned a Lisa in the early 80’s and it still runs!) I have lived thru the transition from OS 6 and 7, then 8, 9 and finally the upgrade to OSX and thru its incarnations up to my current Maverick (aka OS 10.9.4). I am no stranger to changes on the Mac OS. But the new Contacts file within iCloud has me lost. For many years my spouse and I would cross share portions of our personal AddressBook using that softwares publish/subscribe function. It worked great! I could have a list of his relatives/names/phones/addresses in case I needed them - and he had the same for me. With a glance he could see that my sisters middle name was Louise and she hated it. Useful info for when she was being icy to him on a phone call. <grin> We had the shared groups identified as coming from my AddressBook or his, and we could share subgroups or the entire thing as we might choose.
When we went to iCloud and now Maverick, there is no longer a way to share the contact info short of buying the Apple Server software and setting up our own server in house. While I might be able to justify doing so, it is a huge hassle for a very small gain in our case. So that is a last-resort solution, so far.
I would again like to be able to share portions (groups/or sub-groups) of my contact database files with specific individuals, using something like a publish/subscribe feature that would require both parties to agree to the sharing and then once that was done, it should implement automatically and update every time an items is changed, added, deleted on the owners main copy of Contacts. Ideally this would work thru iCloud and its “push update” function. But just to have it working is the goal here. I really do not care HOW it works.
Ive searched, even called a buddy who works the Genius Bar at my local Apple Store. So far, no one seems to have any suggestion other than the aforementioned Maverick Server idea. Frankly with three computers, two printers, a few iPads and iPhones, and a couple of Apple TVs in the house, I am hard pressed to justify the time and energy running a server would require. There has to be a better way to do this. If friends can push their Contact Info to their Android Phones, I should be able to share my Contact files with my spouse! Thanks for your thoughts/suggestions/and hopefully for a solution.

BIP: Upload error (Invalid BI Publisher Security model SBL-RPT-50532)

Hi, We have Siebel 8.1.1.5 running and having trouble integrating with BI Publisher 10.1.3.4.2 . I have setup and configure BIP as per the instructions.
When we try to upload reports from Reports - Standard Templates View, getting the following error messages:
Invalid BI Publisher Security Model Setting (SBL-RPT-50532) && Error (null) invoking method (null) for business service (null).
I have setup the security model to siebel in BIP and able to login tot he console using SADMIN/SADMIN. All the required components are also online and updated the params as per the instructions.
Any help would be greatly appreciated. Thanks in advance!

Hi Hakan,
Please check whether your EAI Object manager is using different srf to one that application set to. In that case try to
set the EAI to same srf Or compile report stuff to that particular srf. And befiore that have you declared the Siebel securiy model setting in BIP.
Please reach me at [email protected] for any issues.
Thanks,
Ravi

XControl publish subscribe?

Hi all
I'm trying to implement a publish subscribe messaging pattern using XControls and LVOOP.
I have various XControls which represent different views of the state of an object.
I want all my XControl (clients) to be updated when the object (publisher) changes its state.
I've achieved this sort of functionality before using VI's running in sub-panels that wait on a user event created by the publisher.
I gather dynamic events are not available with XControls, so have tried to create a list of XControl clients that could be notified by a XControl method call.
I've found a way of notifying individual clients by creating a method that fires the Display State ability but really want to manage all the XControls as a collection.
An array can't seem to store references for the XControls as each is a different type.
I've also tried using a Data Value Reference for each XControl reference hoping that this generic type could be stored in an array but no joy.
The only way I've found is for the main vi to register for the publisher user event and then call the notification method of each XControl explicitly. This messes up the main vi and is not an elegant solution.
Does anyone know a way of achieving my desired functionality?
Thanks in advance for any responses!

I have attached a little sample of what I thought might be nice.
I am building a P&I diagram out of DSC elements.
The valve will ultimatly get more properties like OPC tags, names etc.
I thought to attach the pipes to it so they get automatically activated, when the valve turns on.
But I guess that would require some extra programming anyway because there will be two endpoints on the sides of the pipe to control a flow.
Casting to more generic, even only a control, is obviously not possible.
Hierarchy for Xctrl is also not provided, no inheritence.
Is there any another way to have a class with a Control style FP ?
I am still at the beginning of the project so I have more options to think of......

Publish/Subscribe

hi,
i want to try out publish/subscribe, but i dono where to start with and how to go abt. can anyone advise me like the softwares and tools i can use, what do i study for that would be very much useful.
thanks in advance !

I am not sure about 8i, but if you use Oracle9i, then administration of AQ is included in Enterprise Manager.
However you cannot see there the content of messages on the queue; just the number of messages in individual states.
Anyhow, I would advice you to move to Oracle 9i, if you can; queues have some fine new features there.

Entity Object Publish/Subscribe Events Wizard

Hi,
I'm interested in knowing how exactly works the Entity Objects Publish/Subscribe Events, anybody could help me? Redirecting me to any doc web page, pdf, .... or maybe telling me a little bit more that I can imagine about how it works.
Thanks in advanced.

Repost for a better format, sorry...
I did a quick test on Departments and Employees tables in HR schema.
1, Added CommissionChangeEvent as published event for Employees entity. Set the new commission value (Number) as parameter. These are the generated methods:
* Adds <code>l</code> as an event listener for the event CommissionChangeEvent
public void addCommissionChangeEventListener(JboEventListener l)
((EmployeesDefImpl)getDefinitionObject()).addCommissionChangeEventListener(l);
* Removes <code>l</code> as an event listener for event CommissionChangeEvent
public void removeCommissionChangeEventListener(JboEventListener l)
((EmployeesDefImpl)getDefinitionObject()).removeCommissionChangeEventListener(l);
* Publishes the event named CommissionChangeEvent
public void CommissionChangeEvent()
((EmployeesDefImpl)getDefinitionObject()).publishCommissionChangeEventEvent(createCommissionChangeEventEventData());
* Creates event data method for event CommissionChangeEvent
public JboEventObject createCommissionChangeEventEventData()
JboEventObject eo = new JboEventObject(this, "CommissionChangeEvent");
try
eo.put(new String("CommissionPct"), getAttribute("CommissionPct"));
catch(Exception ex)
ex.printStackTrace();
return eo;
2, Change setCommissionPct method as this:
* Sets <code>value</code> as the attribute value for CommissionPct
public void setCommissionPct(Number value)
setAttributeInternal(COMMISSIONPCT, value);
System.out.println("From EmplyeesImpl.java, Commission Pct is being changed. Firing the event...");
//fire event
CommissionChangeEvent();
System.out.println("Event fired from EmplyeesImpl.java on department ID: " + this.getDepartmentId());
3, Created a method in DepartmentsImpl.java like this:
public void eventFired(Number theNewPct)
System.out.println("In departmentsImpl: event fired with param: " + theNewPct + " on department id: " + this.getDepartmentId());
4, In Entity editor, set enentFired method as to be invoked on event.
Here's the output when change commission:
From EmplyeesImpl.java, Commission Pct is being changed. Firing the event...
In departmentsImpl: event fired with param: 0.5 on department id: 100
Event fired from EmplyeesImpl.java on department ID: 100
Looks like this is a nice inter-entity communication mechanism. It can pass paramter and recognize FK link correctly. Not sure whether it can be used to interact with external message queue, though...

Multiple listeners don't work for publish subscribe?

We wrote a publish/subscribe system based on JMS. It works fine so long as there is only one subscriber/listener. Normally this listener resides in the ejb space. Once we introduce another listener (e.g. by running another java program on the same host), the
          original listener STOPPED receiving messages -- is this a WLS bug ?


Well pub/sub wouldn't be pub/sub unless it allowed for multiple
          subscribers.
          I think that 6.1SP2 had problems with certain combinations of listeners,
          in particular MDB and non-MDB. (Not sure.)
          What is your version and service-pack level?
