Dequeueing messages in enqueue order

Is it possible to determine the order in which messages were enqueued when two or more processes are running concurrently and enqueueing messages to the same queue? In the FAQ section of the AQ documentation it states that if two or more messages are enqueued at the same time the STEP_NO column of the queue table can be used to determine the enqueue order. But apparently this only works when the messages are enqueued in the same queue session.
In my situtation I'm using Oracle8i Enterprise Edition Release 8.1.6.0.0 and I have two or more processes, each with its own queue session, enqueueing and dequeueing messages to the same queue. I have to be sure that the messages are dequeued in exactly the same order that they were enqueued. How do I determine the order that two messages with the same enqueue time were enqueued when each message was enqueued a in different queue session?
Thanks for your help.

The solution I found is to use a loop to dequeue messages in order, rather than by the supplied msgid, and to use DBMS_LOCK to prevent the callbacks from processing messages in parallel.
create or replace PROCEDURE notifycb(
context IN RAW,
reginfo IN SYS.aq$_reg_info,
descr IN SYS.aq$_descriptor,
payload IN RAW,

dbms_lock.allocate_unique( 'NOTIFYCB_LOCK', lockhandle );
lockstatus := dbms_lock.request( lockhandle, DBMS_LOCK.X_MODE, release_on_commit => TRUE );
IF lockstatus != 0 AND lockstatus != 4
THEN
RETURN;
END IF;
BEGIN
LOOP
dbms_aq.dequeue(
descr.queue_name,
dequeue_options, message_properties,
message, msgid );
INSERT INTO xmltest

DEQUEUING ORDER DIFFERS FROM ENQUEUING ORDER,URGENT ONE, PLS HELP

Hi ,
we are using ORACLE ADVANCED QUEUING for queue functionality.
our Oracle version is Oracle 8i release 8.1.5
Sometimes dequeuing order differs from enqueuing order. we are
enqueuing to the queue using default options only , i mean we
are not setting any prriority for messages .We are enqueuing 100
messages continuously to the queue.After completing enqueuing we
are dequeuing from the queue first in browse and then in remove
mode. We are using thin driver for database connectivity. If U
have any idea about this problem pls feel free to share with me .
Thanx in advance
Regards
Shilda Joseph
see the code snippet
enqueuing
aqMsg = qOracleQueue.createMessage();
aqRawPayload = aqMsg.getRawPayload();
byMsg = sMsgInfo.getBytes();
aqRawPayload.setStream(byMsg, byMsg.length);
AQEnqueueOption aqEnqueueOption = new AQEnqueueOption
qOracleQueue.enqueue(aqEnqueueOption, aqMsg);
dequeuing
aqDequeueOption.setWaitTime(1);
aqDequeueOption.setDequeueMode
(aqDequeueOption.DEQUEUE_BROWSE);
aqMsg = qOracleQueue.dequeue(aqDequeueOption);
//removing
AQDequeueOption aqDequeueOption1 = new AQDequeueOption
aqDequeueOption1.setDequeueMode
(aqDequeueOption.DEQUEUE_REMOVE);
AQMessage aqRemMsg = qOracleQueue.dequeue
(aqDequeueOption1);

As other members adviced
Please check the following as a list
1) Check first fi the Material is in APO relevant
2) Check if it has active integration model in cfm5 (R/3)
3) Check if the material has no blocked queues in /n/sapapo/cq (APO)
If there are any blocked queues please clear them accordingly.
4) After that perform a reconciliation of the transactional data through.
/n/sapapo/ccr(APO). perform it only for that material and on planned orders.
If there are any errors it will usggest you to follow few steps.
5) then again go back and check the /n/sapapo/cq transaction.
6) Check if the material and its location has publication Types maintained in SPRO transaction.
7) Check if the change pointers of this Planned order exists in /n/sapapo/c5
This si change pointers transaction , soemtimes you can release ti from there also.
If you still have problem, give the resutls of the following for reference.
Let us know once you perform all these.
8) Incase you need to perform the consistency checks externally.

Dequeue message enqueued by different Oracle user

I have two applications say A and B both are connected to same DB using differenct users i.e. UserA and UserB. The A application is enqueuing messages in AQ such as AQ_QTAB.ENQ_UI = 'UserA'.
My spring based application(using spring AQ api) is connected with DB using UserB and listening on same AQ but I am not able see/dequeue message placed by UserA. However, if enqueue any message using UserB, it is properly dequeued by my listener.
Can any one please help me out? What sort of preliviges / propertiese I need to set.
Thanks

Do you get an error or is it simply not getting a message? If you have insufficient privileges I'd expect an error e.g. ORA-01031:Insufficient Privileges
Here is the procedure for granting enqueue/dequeue privileges to other users of a queue:

Dequeuing messages not working

I am trying to dequeue messages through the use of a java durable subscriber. That is the only subscriber. I successfully get the message and then call the method _session.commit();. Neither throw any errors and I am confused as to why the queue shows the message as processed yet it is still in the queue. Is there an orcale process that needs to be running to remove these dequeued messages? Propagation between databases is not a valid solution. So, some of the examples do not hold for my current setup.
my setup:
oracle 9i
create table, schema, objects, trigger to push jms messages into queue
java client to dequeue messages.
One strange thing I notice, at least to me, is that in order for the trigger to place messages into the queue, i need to either start the java durable subscriber up so it creates a subscriber or run the following: EXECUTE create_subs ( "name", "queue_name", null, null );. Now do I now have two subscribers once I start the java client up after running the PL/SQL command?
per my requirements I need to be able to queue things through a trigger, thus I need to be able to queue messages without having a java durable subscriber running.
Is there a way to determine who is subscribed? For some reason I am not seeing the information i need in any document or on any list.
Any help would be greatly appreciated.
Thanks,
James

createDurableSubscriber creates a new subscriber or gets an handle to an existing subscriber.
When you enqueue a message - you must either have created the subscriber or explicitly specified the recipient during the publish. From what you are seeing it seems that you are trying to enqueue a message without creating the subscriber.
If you want to do this then you must explicilty specify the recipient in the publish call. You'll need to use OJMS extensions in AQjmsSession to do this. The recipients can be specified as an array of AQjmsAgent s

Dequeue Messages queued by caprture process

RDBMS Version: 10.1.0.4
Operating System and Version: WINDOWS 2003 SERVER
Error Number (if applicable):
Product (i.e. SQL*Loader, Import, etc.): Oracle Streams
Hi,
Can I do the following.
I had set up couple of databases for replication using ORACLE STREAMS in hub configuration(One central and many local). My problem is that sometimes some of the connection between them will not work for a significant period of time. That's why I need some tool to move the data.
So I decide to dequeue the which are captured by the CAPTURE process and to process them with a PL/SQL program, save their payload in a file or external table and then trough some way to bring this data to the master server and the other way round.
But I can't dequeue messages because the agent created for the propagation process has no name and I can't dequeue messages if I don't have the CONSUMER.
All examples that I saw in Metalink use already propagated messages with a propagation process.
So I need some other way to propagate my messages different then propagation process! The task is even more complicated because at the central DB some of the messages has a multiple consumers...
Any suggestions?

Wel in 10g it is just as simple as: create a apply-process by adding a table/schema rule that matches the enqueued messages. If you have a captureprocess for several tables off a schema, then a schema rule for that schema owning those tables would do. Then with the set_enqueue_destination api you can add a queue on this rule. Which means that the apply process won't apply those messages but reroutes them on your user-queue. This queue you can create by yourself but it must be of type 'sys.anydata'.
The messages enqueued on that queue by the apply process can be dequeued by a user process.
So just put-in an apply process that dequeues the captured LCR's for you and enqueues them on your user-queue. And then you can dequeue them.

Martien

AQ message notification dispatch order

Hi,
My apologies if the answers to these questions are in the docs, but I cannot find them!
I need to understand the order in which asynchronous notifications will arrive at a client, as it will be a large overhead to check whether a new message has been superceded by a by an earlier arrival (determined using message enqueue times).
Two issues:
1. Is there a strict order in which notifications for a specific client are dispatched? I.e. can we guarantee that the order in which notifications are made matches the order messages where enqueued?
2. How does the client receive these notifications? Are there multiple threads listening for the notifications, or just a single thread?
Pointers to relevant doc would be welcomed!
Thanks,
Richard.

Actually, I think I can answer much of my own question...
It doesn't matter when notifications are posted! As long as we explicitly DQ the messages, because we choose to DQ the oldest unread message. This message is marked as read and the next DQ picks up the next message in the sequence (note: assumption here is queue table orders on enqueue time).
The only problem then is if the client has multiple (notification) threads which can asynchonously receive notifications (and aysnchronously DQ the notifications - which may result in out of sequeunce messages if there is a network delay?). We can, of course, do something about that ourselves by synchronizing the callback functions.

Does listen get unblocked if there is uncommitted dequeued message

Here is the scenario.
I have 2 threads.
1 comes in; Does listen on a multi consumer queue. Gets a message and starts
processing.
At this point 2 comes in; Does the listen; At this point there are no new messages
on the queue. But thread 1 has not committed the dequeue. Will the listen wait
for the duration specified ? or will it return right away?
If it did return right away, then I cannot really do a listen until the thread 1 has committed.
What is expected behavior?
Thanks
Vijay

The answer to your question is I don't know because I would never enqueue or dequeue messages with default parameters. Not only is it a bad practice in that behavior can potentially change after upgrading or applying patches but doing so makes maintenance infinitely more difficult, as you are now discovering, because no one necessarily remembers for each version what the default behavior is.
When you want a specific behavior you code that specific behavior.
Read the docs on the following:
dbms_aq.dequeue_options_t
dbms_aq.enqueue_options_t
dbms_aq.message_properties_t
Then define the properties you want.
You can find some information about them here:
http://www.psoug.org/reference/dbms_aq.html
The docs are at http://tahiti.oracle.com. Search for them by name.

Code sample to dequeue messages

I am looking for a code sample to dequeue messages from CRM OD? How do I retrieve the xml file after it is generated. Do I need to use a web service to retrieve that?
Preference would be to get the code snippet in java, but not necessary.
Thanks.

Hi,
I'm assuming you are referring to integration event messages? If so, then yes, you do need to use WS in order to retrieve them from CRMOD. Please refer to the CRM On Demand online help for Integration Events. It will provide details on downloading the WSDL file for Integration Events and the schema files which are required to process the events once they are retrieved. The WS User Guide contains details regarding the use of the GetEvents and DeleteEvents methods to retrieve and delete events from the queue.
Sorry, I don't currently have a code sample that I can provide.
Thanks,
Sean

"Error while reading Exceptions" - Message No. /SCMB/ORDER 351

Hello,
An error message that we are getting as "Error while reading Exceptions" - Message No. /SCMB/ORDER 351 while entering a Work Order Number in the 'Work Order details' screen in the SNC Web UI. So, please let us know how to tackle this error in SNC.
Regards,
PCN

Hello Pavan,
This message can occure at multiple places. Most of these are status reading and checking in the /SCA/CL_SVORDER class. The following methods can throw this message:
CHECK_ITEM_EXCEPTION_STATUS
You can set a BP at line 20 and debug the STATUS_CHECK function.
GET_ITEM_EXCEPTION_STATUS
You can set a BP at line 29 and debug the STATUS_READ function.
READ_ITEM_EXCEPTION_STATUS
You can set a BP at line 31 and debug the /scmb/cl_odm=>get3_by_id method.
I hope this will help you.
Regards,
Richard

How to Configure a Pop Up Message in Sales Orders

Hi,
How can I display a message when creating or changing sales orders? I need the configuration steps for 4.6.
Thanks,
Sai.

Hi,
First you need to make an entry of your pop up message in the sales text view of the material master and when the user enters that material, he will be able to see that message. The Config part is in spro/sd/basic func/text control. You need to define the text types, access sequences and the text determ procedures.
You have to maintain the desired text in the material master sales text editor and turn on the indicator 'Display texts during transfer' under Text control in configuration for the sales order-item for the material sales text. This will display a Pop-up message when booking orders
Reward points if found helpfull...

Customer error message in sales order on save

Hi Friends,
as per requirement i have to raise the error message and system should enable the field to change values. This should happen when condition is not met on Saving of Sales order.
For this, i have used the user exit USEREXIT_SAVE_DOCUMENT_PREPARE. But the problem is system throwing error message and all r in display mode only. as per my requirement system should allow to change the error value field.
i have verified many posting in this SDN, but nothing is working out.
Please guide me, how to raise the error message and system should enable that filed.
My doubt is where should i raise the error message in sales order (MV45AFZZ)??? if any badi to raise the error message also fine for me. I tried many ways like... message with display like..... and set / get parameters and badis.... but not able to find the correct solution.
Thanks in Advance.
Bala

Hi
You need to use check for enahcement spot, which will be help to you.
Bcz you are throwing custom error message in the standard transaction, once the error is display, you could not able to change the values. your prob can be solved by using the enhancement sport.
This is include name (Include:MV45AF0B_BELEG_SICHERN).
In the above include, you need to create a enhancement spot after this spot (ENHANCEMENT 16 OI0_COMMON_SAPMV45A.)
write your custom code and while displaying an error message. set flag = 'x', then use below code. It will display error message once you press ENTER, you will get the sale order in change mode, you change the values.
IF flag = 'X'.
          fcode = fcode_gleiche_seite.
          perform fcode_bearbeiten.
          ch_subrc = 4.
          exit.
        ENDIF.
